The SPS-7110V-2TG is a dual channel optical single mode transmitter module designed to transmit 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 two independent 1310 nm laser transmitters. Each transmitter can transmit signal from 50 Mbps to 1.5 Gbps with up to 30 km of single-mode fiber when using the SPS-7110VW-2RG as the receiver. A maximum distance of 21 km is achievable with 1.5 Gbps pathological signals.
