WDM Transport
Model 2823 offers high crosstalk
rejection and low optical insertion loss.
Allows the user to configure most
standard single-mode Force, Inc.
fiber optic data links.
Accommodates two signals being sent in
the same direction on one fiber.
Excellent for use with DBS/
CATV systems.
A wide operating temperature
range makes the Model 2823
ideal for a variety of applications.
Model 2823: Multiplexer/Demultiplexer
The Force Model 2823 Wavelength-division
Multiplexer (WDM) allows a single fiber to be
used to simultaneously transmit two optical
signals of different wavelengths. The WDM at
the transmit end combines a 1310 nm signal
and a 1550 nm signal for output onto a single
fiber. The WDM at the receive end separates
the two signals onto two output fibers with
minimal crosstalk and low insertion loss.
There are two basic models; the 2823 WC,
which offers high levels of optical isolation,
and the Model 2823WD, which offers ultra
high levels of optical isolation. Over one fiber,
the Model 2823 can transmit either dual
unidirectional data or video, bidirectional
data or video, or video and pan-tilt-zoom
control.
