1 Baseband Video / 2-8 Audio / 1-4 DVB-ASI or SDI Fiber Optic Multiplexer

The F-1V2A1ASI is a broadcast quality baseband - composite video audio and  SDI or DVB-ASI  over fiber multiplexer. 
This unit also incorporates baseband video / Audio and digital  serial channel for transporting DVB-ASI or SD-SDI transport streams.
We offer off the shelf and custom solutions for multiplexing many types of signals onto a single fiber.  DVB-ASI is a common carrier for MPEG-2 and MPEG-4 Transport Streams.  Depending on the bitrate of the MPEG TS, 10 or more streams can be carried in a single ASI signal.  These signals are used frequently in Digital Video Broadcast.  A common request is to transport DVB-ASI channels over fiber in addition to baseband video and audio.  The F-1V2A1ASI is a video multiplexer and video to fiber system that carries one channel of baseband video, two channels of audio, and one DVB-ASI or SDI channel over a single fiber.  We can also build units with more video, audio, or ASI channels by request.  We also offer bi-directional transport over a single fiber.  Meaning we can transport signals in both directions at the same time over just one fiber.  The video and audio signals are transported by 10 bit digital transmission techniques which eliminates signal degradation and produces broadcast quality transport.  Our units work with standard singlemode or multimode optical fiber with fiber optic transmission distances of up to 120 km when used with singlemode fiber.
