DESCRIPTION
 The
320 (322/324/328) Series is a high performance
Bi-directional Fiber Optic Video/ Audio and optional
Data Transmission System. It provides simultaneous
transmission of two, four or eight baseband digitized
video channels, stereo audio (balanced or unbalanced)
and RS232 or RS422 data channels over a pair of
optical fiber. It supports 850nm or 13OOnm multimode
operations and 13OOnm or 1550 singlemode operations.
The 320 Series offers reliable performance at
distances up to 50km for singlemode operations
with DFB lasers, and up to 1 km for Multimode
operations. The 320 Series provides BNC connectors
for video Ports, terminal block type connector
for the audio ports and DB9 connector for data
ports. Standard optical connectors are ST type
for multimode and FC-type for singlemode. The
power, optical link and channel activities can
be monitored by front panel LED indicators. The
units are contained in I .71" high x 17.03" wide
x 12.0"deep (four channel) or 3.46" high x 17.03"
wide x 12.00" deep (eight channel) modules.
