PMC Unveils OTN-based Fronthaul for C-RAN Architecture

PMC-Sierra unveiled an OTN-based solution for fronthaul networking in Centralized Baseband RAN (C-RAN) architectures used for LTE and LTE-Advanced systems.

The OTN solution meets the 3GPP specifications for end-to-end latency and jitter while multiplexing multiple CPRI signals onto a single 10G wavelength. PMC said this OTN fronthaul architecture substantially reduces fiber consumption in the access network. The company is offering a reference design based on its existing HyPHY 20Gflex and HyPHY 10Gflex devices.

“Solving the mobile fronthaul networking challenge is the key to enabling C-RAN,” said Dr. Chih-Lin I, chief scientist of wireless technologies, China Mobile Research Institute, CMCC. “CMCC is looking for more cost-effective, scalable and carrier-grade fronthaul solutions. As the standard protocol for carrier-grade transport, OTN is a very compelling option and we’re excited to see ecosystem partners like PMC innovating to deliver solutions that address the networking needs of mobile fronthaul.”


“Distributed remote radios in a C-RAN architecture has tremendous potential to address expanding mobile capacity and coverage needs, but it creates a fronthaul networking problem that PMC has now solved,” said Babak Samimi, vice president of marketing for PMC’s Communications Business Unit. “PMC’s new OTN-based mobile fronthaul solution not only meets operator needs, it also allows carriers to build on their end-to-end OTN strategy and benefit from the operational efficiency and management simplicity that comes with a converged network.”
