The FTD4/FRD4 fiber transmitter and receiver provide transmission
of four bidirectional data channels over one optical fiber in a two-slot
wide design. The FTD4 transmitter and FRD4 receiver can be used
with multimode or single-mode optical fiber. When using
single-mode fiber, the FTD4/FRD4 transmitter and receiver offer an
optical budget of 23 dB and provide a transmission distance of
69 km (42.9 mi).
The FTD4/FRD4 plug-and-play design ensures ease of installation by
requiring no electrical or optical adjustments. Modular in design,
FTD4 and FRD4 units can be rack-mounted using the EURACK/
USRACK chassis, or stand-alone modules can be placed on a desktop
or mounted to a wall (wall mount kit not required).
For stand-alone and wall mount installations, external power is
required for the FTD4/FRD4 units. The units can be powered with
the recommended FEXTPS fiber external power supply.
