The fiber optic FM video transmitter/data
and audio transceiver shall be an IFS
VADT4930WDM interface. The unit shall
use lasers and wavelength division
multiplexing to transmit video and receive
audio and data signals over one optical fiber.
Compatible video receiver/data and audio
transceiver shall be an IFS VADR4930WDM
interface. The unit shall use integrated
wavelength division multiplexing devices. The
transmitter shall have LED power indicator
to show presence of input power and shall
be fully color compatible. The unit shall
provide for transmission of video, data and
audio signals over distances of 41 miles (66
km) without requiring manual adjustments.
All printed circuit boards shall be
manufactured from Mil-Grade specification
circuit board material. The housing shall be
all metal construction with all connections
identified with silk screened labels. The unit
shall be available in both rack mount and
surface mount versions. The units shall have
solid state limiters on all power lines which
shall provide for automatic reset. The rack
mount configurations shall have an internal
D.C. power supply and a short circuit in one
unit shall not affect operation of other units
powered from the common power supply.
The rack mount units shall be hot swappable
with no risk of damage to other units during
replacement. The unit shall be U.L. Listed.
