DESCRIPTION
 The
standard 271/272 system is designed to transmit
one (1) NTSC/PAL base band video channel in one
way, with bi-directional one (1) audio channel
and/or one (1) serial data (RS-232/RS-422) channel
over one multimode or singlemode fiber. Versions
with multiple audio/data channels are also available.
The 271/272 Series is a low-cost and high-performance
Unidirectional Fiber Optic Video Transmission
System with Bi-directional Audio and/or Data.
The 271/272 comes with two packaging options:
a rugged, standalone, and compact unit, or a plug-in
card for a card cage system. Panel connectors
are provided for video (BNC), audio/data (terminal
block), and fiber connection (SC-type for singlemode
and multimode fiber). They are also easily monitored
by separate LED indicators for power, optical
link, and channel activity. The units are powered
by +12VDC. The 271/272 design is capable of addressing
a variety of non-standard configurations.
