New video: CPRI over OTN demo at OFC 2015 points way to future C-RAN networks for mobile

The following 3-minute video shows a working demo of IP Light’s new Mobile Fronthaul (MFH) IP that packages CPRI streams from remote radio heads (RRHs) and maps them into OTU2r containers for transmission over OTNs (Optical Transport Networks) to centralized baseband units (BBUs) using the new ITU-T SG15 TD 289 specs for mobile fronthauling. CPRI is the digital interface standard for mobile base station analog front ends. OTN is the existing, high-speed optical infrastructure for long-distance digital communications. CPRI over OTN is one promising approach to fronthauling that can make C-RANs (Cloud or Centralized Radio Area Networks) possible. IP Light’s MFH IP is shown running on a Xilinx Kintex-7 FPGA at OFC 2015.
