FDT-6604-55 is a serial digital SDI to fiber optic converter that supports serial digital data rates from 143Mbps up to 2.97Gbps (1080p). SDI outputs are reclocked copies of the input providing excellent jitter and return loss specifications. It is fully hot-swappable with all active components on the front removable module. No active components are installed on the rear I/O connection module. This design greatly reduces down-time eliminating any need to access the back of the rack frame.
