Microsemi and China Telecom to optimise 5G with OTN Solutions

By News Desk On Jun 14, 2018

Microsemi Corporation has announced its collaboration with China Telecom Beijing Research Institute. The joint efforts will go in developing next-generation optical transport solutions to meet the stringent requirements of 5G. China Telecom is leading the Next-Generation Optical Transport Network Forum (NGOF) consortium formed to drive industry collaboration and technological innovations to define converged optical transport network (OTN).
As part of this collaboration, Microsemi is bringing to market the DIGI-G5, the newest member of DIGI OTN processors, supporting new 5G optimized architecture. This enables the stringent synchronization, latency and network slicing requirements being placed on optical networks to support 5G deployments.
“China Telecom plans to be the pioneer in both 5G commercial service and 400G OTN network commercial deployments. A mobile-optimized converged metro, multiservice and cloud-based OTN transport network is critical to both initiatives. The availability of Microsemi’s DIGI-G5 will help the industry deliver a new generation of OTN equipment to enable the 5G era,” said Zhang Chengliang, vice president, China Telecom Beijing Research Institute.

“As a founding member of NGOF along with China Telecom, Microsemi is innovating and optimizing OTN for mobile applications and DIGI-G5 is bringing together the critical pieces like synchronization, latency, and network slicing needed for 5G,” said Babak Samimi, vice president and business unit manager for Microsemi’s Communications business unit.

With the promise of up to 50x lower end-to-end latency, the optical transport network will play a critical role in enabling ultra-reliable low latency communication (uRLLC) applications such as autonomous vehicles. New architectures leveraging hard traffic isolation will further enhance the business opportunities network slicing is set to bring for mobile operators.

DIGI-G5 offers differentiating features and innovations to support the 5G era:
· New OTN 3.0 rates, enabling flexible (FlexO) and fractional 100G+ transmission
· Comprehensive Ethernet support including 25GE, 50GE and 100GbE
· Close to 1 microsecond datapath latency
· Supports hard traffic isolation and slicing over OTN
· High precision nanosecond level IEEE 1588 PTP timestamping accuracy
· Integrated G.HAO bandwidth-on-demand processing for OTN switching networks closer to the access
