The SPS-7110V-1T1RG is a optical single mode transmitter/receiver module designed to transmit/receive optical serial digital signals as defined in SMPTE 292M/297M/259M. It supports from 50 Mbps to 1.5 Gbps and is specifically designed for transmitted the SMPTE 292M, SMPTE 297M and SMPTE 259M SDI pathological patterns. It is with the SFP 20-pin connector to allow hot plug capability. It is with 1310 nm laser transmitters. The transmitter can transmit signal from 50 Mbps to 1.5 Gbps with up to 30 km of single-mode fiber. A maximum distance of 21 km is achievable with 1.5 Gbps pathological signals.
