ALISO VIEJO, Calif., Jun. 13, 2018 – Microsemi Corporation, a wholly owned subsidiary of Microchip Technology Inc. (Nasdaq: MCHP), today announced its collaboration with China Telecom Beijing Research Institute to define and develop 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) which meet the needs of 5G deployments. As part of this collaboration, Microsemi is bringing to market the DIGI-G5, the newest member of its award-winning DIGI OTN processors, supporting new 5G optimized architecture that enables the stringent synchronization, latency and network slicing requirements being placed on optical networks to support 5G deployments.

5G's variety of use cases will impose new requirements like network slicing, stringent latency and timing synchronization on the underlying optical transport networks. With 25G, 50G and 100Gbps port rates planned for 5G remote radio heads, the traffic flow from the radio to the mobile edge will dramatically increase. With the promise of up to 50x lower end-to-end latency, the optical transport network will play a critical role in enabling ultrareliable 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. 

"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," said Zhang Chengliang, vice president, China Telecom Beijing Research Institute. "The availability of Microsemi's DIGI-G5 will help the industry deliver a new generation of OTN equipment to enable the 5G era."
