Huawei introduces programmable 2T WDM prototype

Telecom Lead China: Huawei has launched programmable 2T
WDM prototype.

The Chinese telecom equipment maker said the prototype
increases the maximum data rate by 20 – fold, from 100Gb/s to 2Tb/s per-channel,
and expands the fiber capacity to 56Tb/s by utilizing both the C and L band’s

Industry will benefit as it is now possible for two
billion people to communicate simultaneously through just one pair of fibers.

“As our world becomes ever more digitized, Huawei
works to accelerate the development of next-generation optical
telecommunications networks in order to provide the highest quality
communications services to our customers around the world,” said Jack Wang,
president of Huawei Transport Network Product Line.

In 2012, we launched the world’s first 10 petabit
all-optical switch prototype, the highest spectrum efficiency WDM prototype,
the first pan-European 400G field trial, and the programmable 2T WDM prototype
this time,” Wang added.

Huawei prototype is designed to improve spectrum
efficiency and increases the maximum transmission capacity. Along with G.652
fiber and common EDFAs, the 2T signals with 300GHz spectral width can transmit
over a distance of 1,000km without electrical regeneration, symbolizing a
breakthrough in the high-speed transmission telecommunications industry.

The prototype uses flex transceiver technology that
enables a programmable network controller to configure parameters such as the
number of subcarriers, subcarrier spacing, modulation codes and FEC modes,
achieving flexible adjustments in areas including line rates, transmission
distances and transmission capacity. This allows the transport network to turn
the resources into the programmable resilient tunnels, and as a result, offer a
more flexible network and efficient system to users.

Huawei has deployed 100G WDM networks for more than 30
operators worldwide. According to the consultancy firm Ovum, Huawei ranked No.
1 in the global optical network, WDM/OTN, and 40G and 100G network markets as
of Q1 2012.
