1-Channel Bidirectional HD-SDI Fiber Transmitter & Receiver Set with Audio & Data

The FT-3935 is a 1-channel HD-SDI fiber-optic transmitter and receiver pair for bidirectional operation on a single fiber. The transmitter takes HD/SD-SDI video through a 75 ohm BNC input, equalizes and re-clocks it, and sends it up to 20 km over single-mode fiber; the return path carries one channel of RS-485/RS-232/RS-422 data and one channel of balanced analog audio. Rates from 19.4 Mb/s to 1.485 Gb/s cover SMPTE 292M, 259M, 305M, 310M, 344M, M2S and DVB-ASI. Wavelength options include 1310 nm, 1550 nm and 16 CWDM wavelengths via hot-pluggable SFP transceivers, with LED indicators reporting status on both units.
