2×12G-SDI Extender

GIGALIGHT’s 2-channel 12G-SDI optical extender supports a transmission rate ranging from 125Mbps to 11.88Gbps, which can realize the bidirectional transmission of up to 20km of 20km of 2-channel 12G-SDI video signals (the transmission of the two SDI signals is carried out independently), and is backward compatible with MADI, DVB-ASI, SD-SDI, HD-SDI, 3G-SDI and 6G-SDI standards. With GIGALIGHT’s 3G/6G/12G-SDI optical module, one to two SDI signal channels can be expanded for customers.
