100G and Beyond - @Huawei Comments at #OFC2015

What changes will we see as network transport evolves to 100G and beyond? Peter Ashwood-Smith, Technical VP of Optical Product Line at Huawei, breaks it down into a discussion of the control layer and the physical interface.  He sees 100G as the "workhorse" of optical transport for the next 3-5 years. We'll see improvements in density and the adoption on pluggable formats in 100G interfaces. Another factor for 100G is silicon photonics.

Huawei Unveils ONOS-based IP + Optical and Transport

Huawei demonstrated an IP + optical and Transport Software-Defined Networking (TSDN) implementation the based on the Open Network Operating System (ONOS).

The application shown at this week's #OFC2015 show in Los Angeles comprised a number of features including a graphical multi-layer network view of the SDN application system, automatic resource discovery, automatic IP link setup, automatic service provisioning and multi-layer network protection. Huawei also presented bandwidth-on-demand (BoD), transport network virtualization and innovative VTS2.0 applications, which provide network level services that can be customized by tenants, as well as cloud-like resilience.

The demo used the Huawei ONOS-based Smart Network Controller (SNC) and NetMatrix service synergy platform to remotely control a real network constructed with Huawei NE series routers and Huawei OptiX OSN series smart optical devices located in Dallas, Texas.

OIF Shows 56G Electrical Interfaces & CFP2-ACO

At this week's OFC exhibition in Los Angeles, the Optical Internetworking Forum (OIF) is showcasing the first electrical interfaces running at 56 Gbps, effectively doubling the current 28G electical interface specification.  The OIF has five CEI-56G specifications are under development, such as platform backplanes and links between a chip and an optical engine on a line card.

To address power consumption issues, the OIF is pursuing two parallel tracks: using 56 Gigabit non-return-to-zero (NRZ) signalling and 4-level pulse amplitude modulation (PAM-4) which encodes two bits per symbol such that a 28 Gbaud signalling rate can be used. The 56 Gig NRZ uses simpler signalling but must deal with the higher associated loss, while PAM-4 does not suffer the same loss as it is similar to existing CEI-28 channels used today but requires a more complex design.

Luxtera Debuts 100G QSFP28 Module and Silicon Photonics Chipset

At this week's #OFC2015 in Los Angeles, Luxtera confirmed commercial availability of its 100G-PSM4 compliant chipset and QSFP optical module. The company said its low cost single mode products  make it well positioned for an industry-shift from copper and legacy multimode fiber to single mode fiber at volume scale.

LUX42604 Key Features

  • 100Gb optical transceiver
  • QSFP28 compliant module form-factor
  • Four 4 x 26 Gbps independently operating channels, full-duplex operation
  • Multirate: 1 – 25.78 Gbps (per channel)
  • FEC not required for error free operation but also supports Clause 74 and 91 FEC
  • 1310nm PSM4 MSA compliant – as described by www.psm4.org.
  • Proven Light Source and Packaging Technology
  • Extended Reach Up to 2000 Meters
  • Less than 3.5W worst case power

“In 2015, hyperscale data centers are undergoing a tectonic shift as the industry moves to 100Gb, and single mode photonics replace copper to become the mainstream interconnect. Luxtera is at the forefront of this transition with the only optical transceiver technology that can deliver 100Gb speeds with up to 2km of reach at the aggressive cost points needed for these high volume deployments. Today we are introducing our first Hybrid Silicon Photonics architecture products including the industry’s first 1310nm 100G-PSM4 MSA compliant QSFP28+ pluggable module and a fully integrated SiP PSM4 chipset,” said Greg Young, President and CEO of Luxtera.  “Luxtera pioneered the field of Silicon Photonics starting in 2001 and has been in continuous production since the original introduction of 40Gb SiP AOCs in 2008. With these new products we are addressing connectivity needs of hyperscale/cloud and enterprise datacenters with standard compliant products. We look forward to moving further into these core markets by delivering additional high performance single mode fiber solutions."

GigOptix Samples its 3rd Gen 100Gbps Ethernet Chipset

GigOptix announced its 3rd generation chipset for 100Gbps Ethernet datacenter and cloud computing applications.

The HXT8204 28Gbps 4 channel VCSEL driver array and HXR8204 28Gbps trans-impedance amplifier (TIA) receiver array enable the next generation of lower power 100Gbps Ethernet SR4 module and Active Optical Cable (AOC) solutions.

The HXR8204 four channel receiver with integrated TIA provides 60uAPP input sensitivity at 28Gbps with 10-12 Bit Error Rate (BER), AGC and ATC, and a limiting post amplifier stage. The HXT8204 four channel VCSEL driver supports modulation and average VCSEL currents up to 10mA with a dedicated BURNIN capability up to 15mA average current. The 1MHz I2C interface enables full control of all driver functions including input equalization, output peaking and peaking duration, Signal Detect and Squelch, channel polarity inversion, diagnostics such as average current and temperature monitoring as wells as user maskable Interrupts and VCSEL voltage supervisory functions.

“GigOptix is proud to announce our latest 100Gbps Ethernet chipset for the Datacom Ethernet market, which is expected to show 60% CAGR over the next seven years,” said Tom Kapucija, Datacom Marketing Director. “Our third generation solution enables a 20% typical reduction in power dissipation over our earlier chipset solutions without sacrificing performance or robustness. In addition, in certain applications such as Active Optical Cables we see up to 30% power reduction.”

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).
