The OSD391/393 fiber-optic multiplexer transmits two, three, or four video signals and optionally transmits four audio and data channels in one or both directions. An optional reverse channel provides video synchronization. The unit operates to 50 km, although 100 km is possible with optional 1550-nm operation. The multiplexer is immune to electrical interference.
