Blueprint: Beyond 100G in Core Networks – Is Coherent Technology Reaching a Plateau?

by Maxim Kuschnerov, Coriant

100G coherent technology has paved a successful path in terrestrial core and submarine networks since its introduction in 2010. In core networks, a figurative marketing war on beyond 100G capacity has been taking place for some time, with vendors announcing 200G, 400G, and IT transport solutions. However, it has been impossible to ignore the fact that beyond 100G tunable line side interfaces do not live up to the general evolutionary trend of 10G to 100G. While the previous per-channel capacity step represented a 10-fold increase without sacrificing reach or channel-count, a similar step seems very unlikely for interfaces beyond 100G.

Flexi-rate Interfaces - Not Quite Yet What you Would Expect

100G connectivity in the core started out with a 4QAM/QPSK modulation scheme, as shown in Figure 1, where binary electrical signals are converted to a format with four constellation points, which is transmitted in two orthogonal polarizations. The applied coherent detection technology is capable of detecting arbitrary multi-level schemes, which can be used to transmit more bits per time slot. Borrowing from a 30 to 40 year old playbook from wireless communications, optics turned its eyes to more flexible modulation formats like 200G 16QAM (see Figure 1) to increase capacity throughput. While the capacity increases by 100% compared to the classic 100G 4QAM, the reach is roughly a quarter. After a limited market introduction in 2014, this year we will see the first wave of commercial 100G/200G 16QAM interfaces. However, 200G 16QAM leaves no room for margin in manufacturing and does not have the wide appeal of a carrier-grade interface due to its inherent performance limitations. While sufficient to cover a portion of demands in long-haul networks, it is not quite the game changer.

When analyzing the actual reach requirements of core network demands it is clear that a more powerful solution to the minimal reach of 16 QAM transmission is required. Fully flexible transceivers should include a middle ground format of 8QAM. With reach of up to 2,000km 8QAM based solutions hits an ideal sweet spot in core networks while still providing an increase in spectral efficiency of 50%. Wide deployment of flexi-rate interfaces in core networks will not come until the adaptation of the 8QAM format is included in the solution, then living up to the promise of a single-spare fully flexible line interface. Figure 1 illustrates the reaches of a flexi-rate interface with multiple modulation schemes on a cumulative distribution of demands in core networks. 8QAM is clearly the undeniable working horse.


Figure 1: Applying flexi-rate interfaces to core networks with Raman amplification (Note: absolute distances of each scheme depends on fiber and amplifier type, span losses, channel counts, end of life margins, and error correction limits.)

Pushing the Limits – What’s Next in Terms of Differentiation

Flexi-rate interfaces for core optical networks are coming close to the theoretical boundaries of maximum channel capacity. It is virtually impossible to deliver a 400G or 1T long-haul interface while keeping channel count and network architecture the same. Digital signal processing offers still some room for improving error correction codes or the holy grail of fiber optic communication – i.e., algorithms for the compensation of fiber nonlinearity – but the return on investment diminishes drastically. Going forward, optical layer technology like Raman amplification or C+L band systems will be quintessential to increase core network capacity without requiring completely new fiber transmission technologies. Figure 2 shows an overview of techniques going forward for fiber capacity increase.
Figure 2: Improvements for core network channel capacities going forward vs. state-of-the art coherent interfaces

It is clear that the majority of innovation for capacity resides in the optical layer and no longer in signal processing chips. Since these integrated circuits become more expensive with each generation, their product definition has to find a good balance between development costs, power consumption, and feature set. Fighting for a 10% reach improvement with a disproportionately high investment cost is unlikely to lead to a profitable business model for many vendors. Moreover, optimization for very high-end optical performance is likely to reduce the viability of these solutions for lower end applications such as metro transport or datacenter interconnects, which are driven by low power and high density requirements. Thus, the trend for 400G/1T interfaces will shift away from pure optical performance improvements which are valuable only in long haul applications and instead focus more on solutions that can leverage the same design across multiple markets spaces, while delivering the most flexible level of architectural feature integration at the lowest power consumption. This reflects a similar experience in consumer market. While processing speed was one of the major buying criteria in the first age of personal computing, the value perception has shifted towards the application or the battery life of the device. The actual processing abilities of a smart phone or a laptop become of much lesser importance if not practically irrelevant.

Evolution of Core Networks in Light of the 100G Metro Surge

100G is on its path conquering the metro market using a mix of coherent and direct detect pluggable interfaces. Coherent technologies designed for the higher end of the metro market (>40-80km) will inevitably take a large share of the long-haul market. This mostly depends on each vendor’s ability to deliver low power flexi-rate interfaces. While these do not require high-end error correction abilities or highest performing optics, the reach and cost position of these interfaces will make the long-haul market an offer that it simply can’t refuse. A true long-haul network equipment manufacturer will not be able to survive without the mix of high-end and low-end coherent interfaces. While the earlier are likely to be proprietary and more power hungry, the lower end segment is on its way towards generic pluggable interconnects. Figure 3 highlights possible market coverage of several competing interface technologies. 

Figure  3 – Technology market segmentation for colored interfaces

In conclusion, the way forward to 1T interfaces is not a naturally outlined evolutionary step. Multi-channel interfaces will be required for both short reach and long-haul. While the war on costs in core networks is far from over, it looks like the industry is about to experience a different innovation pace in the optical performance craze.

With the performance of digital signal processing chips leveling out, the further evolution of photonic components could be key to enabling the next wave of core interconnects.

Infinera Charts Network Transformation with PICs for Sliceable Photonics

Infinera unveiled two photonic integrated circuits (PICs) for new optical transport systems and line cards scheduled for delivery later this year. The introductions include a sliceable, enhanced PIC, ePIC-500, and an application-optimized PIC, oPIC-100.

Infinera said its new sliceable photonics technology enables the large pool of capacity in a PIC to be divided at a granular optical level.  Each slice can routed in a different direction as it exits the line card or the system housing, usually at the hub. The recipient of the individual slice is a line card or system that matches the capacity, usually at the spoke. For instance, a 500G superchannel originating at a hub location could be sliced into 100G chunks for delivery to multiple spokes.

The new ePIC-500 provides sliceable 500G capacity at the hub location, while the new oPIC-100 provides 100G capacity at the spoke location. While these two new PICs are applicable across all network locations they were developed specifically to support Layer T in the metro.

The introductions come as Infinera positions for a major transformation in network architecture driven by scale and virtualization.  Infinera sees the emergence of two layers:
  • Layer C -- a cloud services layer that supports NFV plus other Cloud delivered services  
  • Layer T --  the transport layer, which is founded on scalable photonics capable of delivering more capacity per line card and system while simplifying the network.
Infinera believes that PICs are integral to the evolution of the transport network and provide significant benefits when integrated into a packet-optical DWDM transport system, there creating an efficient Layer T and ultimately allowing Layer C to thrive.

The company said it has modeled a wide range of applications from metro aggregation to regional long-haul where hub-and-spoke, mesh or ring topologies are common. When using the new PICs, these models showed an estimated average reduction of 28 percent in modules, 31 percent in power and 45 percent in bandwidth inefficiencies as compared to conventional, commercial off the shelf technologies that deliver single-wavelength or super-channel solutions for 100G, 200G or 400G.

“Infinera has been shipping PICs in transport systems, that have been designed from the ground-up, for over a decade," said Dave Welch, co-founder and president at Infinera. "During this time the technology has surpassed over 1.5 billion hours of field operations. Sliceable photonics allows our customers to build networks with scale and flexibility for a wide variety of applications ranging from the metro to the long-haul. It provides a comprehensive tool set for us to be nimble and build market-specific platforms for Layer T as our customers’ needs continue to evolve."

Corning Intros SMF-28 Ultra 200 Fiber

Corning introduced the industry’s first 200-micron fiber with a 9.2 micron nominal mode-field diameter (MFD).

The new Corning SMF-28 Ultra 200 fiber enables the design of smaller, lighter, fully backwards compatible high-fiber, high-density cables. The company said its new fiber complies with the ITU-T G.657.A1 specification while also delivering enhanced bend resistance and seamless integration with the installed ITU-T G.652 fiber base in a 200-micron product. In addition, Corning claims the fiber’s low attenuation improves signal reach up to 10 percent over conventional ITU-T G.652 fiber types and increases coverage as much as 20 percent when served by a point-of-presence or central office.

“Corning SMF-28 Ultra 200 fiber helps solve one of the world’s toughest network challenges – increasing fiber capacity without taking up more space,” said John Igel, vice president and general manager of Corning Optical Fiber and Cable. “With the problem of MFD compatibility eliminated, network operators have the freedom to deploy fiber-rich 200-micron cables to address capacity and congestion – with the proven performance of SMF-28 Ultra fiber.”

Corning's SMF-28 Ultra fiber portfolio can be used for high-performance applications at 100G and beyond, and for next-generation passive optical networks (PONs) and wavelength division multiplexed passive optical networks (WDM-PONs).

Blueprint: The Future of Cloud Communications

by Pejman Roshan, VP of product management at ShoreTel

Who knows what the future holds? Analysts look for the future in current trends, and businesses attempt to create it by meeting their customers’ present needs. At ShoreTel, we make no claims of omniscience, though we do boast a record of impressive foresight into the future of cloud communications, and strive to make that future a reality.

Hybrid UC

The future does not lie solely in the cloud or on-premises; rather, patterns point toward hybrid solutions being the way of the future. The cloud is an incredibly useful tool for storing, accessing, and managing virtualized applications and data. Yet at the same time, on-site phone systems still offer control, availability and resiliency that softphones can’t guarantee. Fortunately, the choice isn’t an either/or situation, and one can get both through a hybrid cloud communications platform.

However, not all hybrid solutions offer the same balance of cloud and premises features, and are often weighted more toward one or the other – based in the cloud with some on-premises features, or vice-versa. So while hybrid will see more growth than cloud or premises solutions on their own, users will be free to decide what balance works best for them. Regardless of what they go with, though, there’s little doubt that vendors offering hybrid solutions will be set for success.

As communications become a blend of physical and virtual, the workspace will follow. The cloud will continue to expand as more users migrate to it, bringing their work and tools with them. Their own “personal” clouds will be a combination of the various components they need, so working virtually is as effective as working from a corporate office. We’re already seeing a continuous rise in mobility, and it shows no signs of slowing, which will lead to a growing virtual workspace that complements and works in tandem with the physical office.

BYOD and WebRTC

In order to support the mobile BYOD environment, applications that let people communicate through and between their various personal devices will be necessary. IT departments will need to put more focus on software apps for that, but technology like WebRTC will make it easier to launch Web collaboration meetings right from the client, which will in turn make it easier to create and join meetings.

Yet no matter what tools you can use to work and communicate with, the user experience can make or break the technology. Now that technology is at the point where we can reach across cyberspace to work and collaborate from anywhere, it needs to be doable in a way that doesn’t drive users mad.

The way we see it at ShoreTel, the best way to provide a good user experience is through a good interface. You need a clean user interface, one that makes good use of space to remain clear and easy to use, which remains singular for different modes of communication. The less people have to switch between screens, apps and interfaces, the better the experience will be for them, which leads to improved efficiency and growth all around.

With all this advancement, what will Unified Communications become? It is our view that UC will advance beyond merely transmitting information back and forth, but will incorporate intelligent organization, providing vital context and sorting for the information transmitted. Unified Communications will continue to grow and incorporate both cloud and premises-based communication platforms and include an ecosystem of integrated applications.

The future is not some far-off thing these days; our predictions follow current trends to see what this year will contain, so in many regards, we are already living in it. It’s never too soon to prepare for what’s ahead, so the time is right to get ahead of the curve.

Acacia Announces Coherent 400G Transceiver Module

Acacia Communications introduced the first flex-rate coherent 400G Transceiver module. Sampling is underway and generally availability is expected in Q2-2015.

The new transceiver, which targets LH/ULH, metro and Data Center Interconnect networks, is powered by the industry’s first dual-core ASIC supporting two optical channels and up to 400Gbit/s capacity including a clear channel single 400Gbps traffic flow, optimized for IP packet transport. Built-in framing functionality supports 100G and 400G OTN and Ethernet clients.

“100G coherent transceivers are currently being deployed in large volumes in long haul, metro and Data Center Interconnect networks,” said Acacia Communications President and CEO Raj Shanmugaraj. “With the availability of Acacia’s low cost flex-rate coherent AC-400 MSA module, we expect to bring even better economies for coherent applications at multiple rates from 100G to 400G.  Powered by the Acacia’s ASIC/DSP and extensive silicon photonic integration for metro and Data Center Interconnect applications, we have been able to extend the performance advantages of an AC-400 module while reducing cost, size and power consumption dramatically. Our new AC-400 provides carriers and content providers with a compelling solution to cost-effectively address capacity needs in their ULH/LH, metro and Data Center Interconnect networks.”

“The ability to launch 400G off a 5x7 Transceiver Module with advanced features like 8QAM and low power is well timed with the growth of the Data Center Interconnect transport market and Acacia’s flexibility to scale from 100G to 400G is a major advantage,” said Simon Stanley, Contributing Analyst, Heavy Reading. “The module demonstrates Silicon Photonics PIC performance for the higher order modulation schemes and makes solutions like these very cost-effective for the market.”

The OpenOptics MSA Consortium has published the first foundational Wavelength Division Multiplexing (WDM) specification for an interoperable 100G WDM standard for 2 kilometer reach, addressing data center interconnect (DCI) requirements.

RANOVUS said this new WDM specification brings together 1550nm WDM laser and silicon photonics for QSFP and optical engine based solutions, enabling lowest-cost, highest density, and highest bandwidth with single mode fiber pair connectivity, to enable data centers to use up to 32 or more channels per fiber strand.

“Our OpenOptics MSA collaboration with industry leaders has resulted in the definition of a foundational WDM specification for data center network connectivity, and having terabit scalability on a single mode fiber pair infrastructure,” said Saeid Aramideh, chief marketing and sales officer for RANOVUS.  “The availability of this specification is a major milestone for our industry which we believe will not only accelerate the adoption of silicon-photonics based WDM solutions for the data center market, but also allow for a scalable terabit infrastructure for next generation datacenter architectures.”
 
“Previously, there was no standard for anything beyond 100Gbs,” said Gilad Shainer, vice president of marketing at Mellanox Technologies. “Now, the industry will have an architecture standard that scales to a terabit and beyond on existing fiber, substantially reduces the cost of hyperscale data center networks.”

Earlier this month, the OpenOptics Multi-Source Agreement group said it plans to contribute its developed wavelength specifications to the Open Compute Project (OCP). The new specification enables data to be streamed at terabits per second over a single fiber.

The founders and supporters for the OpenOptics MSA for Highly Scalable Interconnect Solutions include Mellanox Technologies, RANOVUS, Ciena, Oracle, Vertilas, and Ghiasi Quantum. The MSA combines 1550 nm WDM laser and silicon photonics for optical networking solutions enabling the lowest cost, highest density, and highest bandwidth single mode fiber (SMF) connectivity, significantly improving terabit-scale data center infrastructure ROI.

NeoPhotonics Intros Low Power 100G Transceiver

NeoPhotonics introduced a new compact and dual rate 100G CFP4 LR4 that requires much less power and is half the size compared to the current generation CFP2 form factor.

The new 100G CFP4 transceiver module, which is targeted at both telecom and datacom applications, is designed to fully comply with the IEEE 802.3 100GBASE-LR4 and CAUI-4 Electrical Interface and OTN OTU4 standards for links up to 10km.  It combines CFP4 MSA and MDIO functionality and is interoperable with previous generation of CFP and CFP2 modules.  The 4-channel PIC-based integrated transmitter utilizes NeoPhotonics proven performance and high volume manufacturing platform of 28G EML lasers and drivers, which enable the best in class module performance, especially in OTN applications, inter-operabability and easy deployment.

“The introduction of our new 100G CFP4 LR4 Client transceiver module underlines our commitment to the ultra-high speed segment of the transceiver market,” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “We are pleased to support our customers with their growing demand for 100G by adding production capacity for our CFP2 LR4, which was released last year,” continued Tim Jenks.

In addition, NeoPhotonics announced a micro-Integrated Coherent Receiver (Micro-ICR) which is designed to fully support the OIF implementation agreement OIF-DPC-MRX-02.0, Type 1. The Micro-ICR has a compact form factor that is approximately one quarter the size of the standard OIF 1.2 Type 1 ICR and one half the size of the new OIF 1.2 Type 2 ICR. It is designed to be used in coherent analog CFP2-ACO pluggable modules as well as in high density line cards.

This week at the Optical Fiber Communications (OFC) Conference in Los Angeles, Neophotonics also plans to demo a 16x16 multicast switch (MCS) without drop side amplifiers. The 16x16 MCS will consist of four modular 4x16 MCSs which can be cascaded to encompass 16 directions.
