Huawei to showcase new products for high-capacity transmission at OFC/NFOEC 2012

Telecom Lead India: Chinese gear maker Huawei is
demonstrating new products and solutions for high-capacity transmission at


A press release said Huawei develops optical network
solutions to address traffic growth while minimizing total cost of ownership,
energy consumption, and footprint. These new solutions address bandwidth
requirements for telecom operators for video content and business services.


“Optical technology leadership is a key priority
within Huawei’s research and development groups. We are positioned well to
address the exponential growth of our customer’s networks as we move into and
beyond the 100G era,” said Reg Wilcox, vice president of Network Marketing
for Huawei USA.


Huawei is showcasing the following:


100G Coherent Solutions with Hard-Decision Forward Error
Correction (HD-FEC) and improved performance Soft-Decision Forward Error
Correction (SD-FEC) for high-capacity, Ultra Long-Haul (ULH) applications.


Next-generation 400G technology providing a sneak-peek at
what is on the horizon for improving spectral efficiency by unlocking higher
bit-rate capacities beyond 100G.


Petabit/s Photonic Cross-Connect (PPXC) technology
utilizing a scalable, high-capacity switching architecture for management of
100G+ wavelengths at large add/drop sites of the future.


Huawei is also demonstrating its second-generation 100G
solution, a single wavelength, Optical Interoperability Forum (OIF) compliant
technology utilizing SD-FEC which improves 100G system reach up to 30


The company claims that Huawei is involved in standards
efforts and research to unlock the next capacity leap beyond 100G.


The company is spotlighting its 400G technology utilizing
Orthogonal Frequency Division Multiplexing (OFDM) Polarization Division
Multiplexing-16 Quadrature Amplitude Modulation (PDM-16QAM), enabling up to 16
Tbps of capacity at 100 GHz spacing or 21 Tbps of fiber capacity by removing
guard bands with flex-grid technology.


As 100G and 400G wavelengths proliferate in the network,
new switching architectures will be required to manage increasing bandwidth at
nodal sites. An innovative, highly-scalable cluster switching system is being
demonstrated using Huawei PPXC technology.


This technology leverages Huawei’s expertise in Optical
Transport Network (OTN) and enables switch scalability to multi-Petabit/s
capacity to manage multiple 100G+ wavelengths while providing Gigabit Ethernet
(GE) granularity grooming for bandwidth management.


Huawei and Beltelecom test 100G coherent transmission on
Beltelecom’s live network


Recently, Huawei tested the first 100G coherent
transmission on the live network of Beltelecom, a telecom operator of the
Republic of Belarus.


The trial was performed on a link in the Beltelecom
backbone wavelength-division multiplexing network that connects Russia and
Poland and travels across Belarus. During the trial, 100G services were
transmitted together with existing 10G and 40G services over the same fiber,
while achieving non-regeneration transmission over a distance of 900
