Coriant Outlines Dynamic Optical Cloud Architecture for On-Demand Services

Coriant outlined its vision for bringing a high degree of programmability, automation and control to multilayer, multi-vendor transport networks.

The Coriant Dynamic Optical Cloud will couple the company's metro-to-core packet optical networking capabilities with software-defined networking (SDN) intelligence.

Coriant cited several Dynamic Optical Cloud use cases that it has developed in partnership with Tier 1 operators around the world, including:

  • Application-driven TaaS/bandwidth on demand
  • Multilayer defragmentation
  • Network analytics and workflow management
  • Dynnamamic mobile backhaul resiliency
  • Cloud-bursting

The Coriant Dynamic Optical Cloud includes the company's 7100 and hiT 7300 packet optical networking platforms, the 8600 mobile edge router, and a suite of applications, open orchestration and controllers. It also includes the new mTera Universal Transport platform.

Coriant said it is working to integrated third party routers into these use cases as an initial step toward multivendor implementation. The company is currently engaged in multiple customer trials and will be trialing the commercial offering in the third quarter of 2014.

“Coriant‘s Dynamic Optical Cloud solution reinforces our market leadership in end-to-end packet optical networking following the merger of Tellabs and Coriant,” said Pat DiPietro, Chief Executive Officer, Coriant. “With greater scale, deeper R&D resources and technology expertise, and an expanded portfolio of SDN-enabled products and capabilities, we are well positioned to be the preferred supplier to our customers as their network and service requirements evolve in a cloud-centric world.”



Coriant's Debuts mTera Universal Transport Platform

Coriant introducted its mTera Universal Transport Platform designed to serve a variety of roles in next-gen packet optical networks, including metro-to-LH gateway applications and on-demand data center connectivity. The Coriant mTera platform, which is the first product to come to market since the merging of Coriant and Tellabs, brings together compact, simplified and efficient traffic grooming from Tellabs and photonic-layer technology and system performance from Coriant.

Key attributes of the mTera platform include:

Huawei's 400G WDM Prototype Promises 'Faster than Nyquist'

At the OFC 2014 Conference in San Francisco, Huawei introduced a 400G WDM prototype for ultra-long-haul transmission that employs Faster Than Nyquist (FTN) technology to increase the 400G transmission distance beyond 3000 km.

Huawei said its FTN technology breaks the limit of the Nyquist sampling theorem, which defines a maximum transmission speed for a fixed channel bandwidth, by leveraging spectrum compression and signal distortion compensation algorithms.  This enables the FTN technology to achieve long-haul transmission of high baud-rate signals on existing networks (similar to transmitting a large file that has been compressed, which requires less bandwidth than transmitting the original file).

The technology enables two types of 400G WDM solutions based on 100 GHz channel spacing — a short-haul solution and the ultra-long-haul solution unveiled at OFC 2014. The ultra-long-haul solution, which applies to backbone transmission, adopts 2SC-PDM-QPSK modulation and supports a record transmission distance of over 3000 km. The short-haul solution, which applies to metropolitan area network (MAN) transmission, adopts 1SC-PDM-16QAM modulation and allows high-quality 400G transmission over a single carrier wave. Huawei's single-carrier 400G solution was recently tested on EXATEL's live network in Poland.

“Huawei has been investing heavily in the high-speed WDM field. The new FTN technology introduced in the prototype exceeds traditional technological limits to deliver ultra-long-haul 400G transmission, breaking new ground for the 400G industry,” said Jack Wang, President of the Huawei transmission network product line.

Bright House Tests 400G and 800G Over Live Network with Fujitsu

Bright House Networks, which is the sixth largest owner and operator of cable systems in the U.S., has successfully trialed Fujitsu’s 400G transport technology in its live network.

The trial was Fujitsu’s first 400G trial with a cable MSO used Fujitsu’s 400G optical networking transceivers over the Fujitsu FLASHWAVE 9500 Packet Optical Networking Platforms (Packet ONPs). Upon completing the 400G trial, an error-free rate of 800 G was also attempted and achieved–maximizing the potential of future networking capabilities while showing their commitment to leveraging customers’ investment in their networks.

Fujitsu noted several key technical advancements demonstrated by this trial:

  • Fujitsu’s 400G and 800G Super Channel capabilities enable higher per-channel scalability; 
  • Support for adaptive modulation schemes, including DP-QPSK and DP-16QAM, opens up the ability to optimize spectral efficiency while accommodating dynamically changing reach demands
  • Increased spectral efficiency was achieved with Nyquist filtering techniques reducing optical signal bandwidth.  
  • Nonlinear compensation (NLC) techniques were employed to reduce the resulting optical penalties and extend the achievable transmission distance to overcome nonlinear fiber impairments due to optical transmission.

“Our work with Fujitsu allows us to further advance our current transport infrastructure, from 10G to 100G and now 400Gbps and beyond,” said Craig Cowden, Senior Vice President, Network Engineering, Operations and Enterprise Solutions, Bright House Networks.  “Our technology is part of people’s lives, so we continually invest in our network to deliver new and innovative solutions. This initiative provides us with the ability to upgrade the amount of bandwidth available on our existing DWDM infrastructure to support the ever-increasing High Speed Data requirements of our customers and new initiatives, such as fiber to the home, for years to come.”

Huawei Releases Wavelength-based Multidimensional All-optical Cross-connect

At the OFC 2014 show in San Francisco, Huawei showcased a wavelength-based all-optical cross-connect technology that operates in 8-dimensions (80 waves per dimension).  The optical cross-connect prototype implements a free cross-connect of 640 x 640 waves.

Huawei said its optical cross-connect prototype uses an industry-leading optical engine that enables a programmable million-pixel array to be integrated into a 1 cm2 silicon wafer. This is like integrating a million tiny mirrors into a space no larger than a coin; the engine can then control the cross-connect directions of the wavelengths by manipulating these "mirrors".

The innovation is seen as an important step in the evolution from transport networks to all-optical networks.
