The WDM Lite
(TM) Bi-directional Coupler is
a passive device that allows for optical
transmissions in both directions in
one fiber. It is independent of optical
transmission equipment and therefore
existing transmission equipment can
be used with these devices. It operates
with any wavelength in the 1550 or 1310
nm window (must be specified on order).
For an installation, two units are required
per fiber, one at each end of the fiber.
The communication equipment's optical
transmit and receive connections are
made to each unit’s In and Out ports.
One cable fiber is connected to the
common ports of both units to complete
the installation. This enables optical
transmission in both directions on one
fiber.
As shown in the
implementation diagram, the number
of fibers required for a bi-directional
communication system is reduced from
two to one, therefore in effect doubling
the fiber’s transmission bandwidth.
