Features:
The Finisar OADM-4 Plug-in Module is a passive optical add/drop multiplexer
designed for metro access applications that represents the state of the art in fiber
optics design. The OADM-4 Plug-in Module adds/drops four CWDM wavelength
channels from network traffic and passes the other channels. Finisar's unique CWDM
design maps the channel into separate two-fiber paths, going in opposite directions
into the network (East/West).
Added/dropped channels are interfaced to any of Finisar's CWDM transceivers on the
equipment side. A grid of eight CWDM wavelengths is available from Finisar. The
OADM-4 Plug-in Module plugs into one half of a 1RU, 19" rack mount chassis for
simple installation and modularity. This Chassis based system allows a network
equipment manufacturer to add WDM capability to any existing network device that
supports GBIC and SFP interfaces.
The equipment ports of the OADM-4 plug-in module are color coded to match the
wavelength of Finisar's CWDM transceiver. This allows ease of installation and
trouble shooting without having to remove the transceiver from the local equipment.
The Finisar OADM-4 plug-in module delivers dramatic cost savings to network
equipment manufacturers, enabling them to develop metro access systems that are
lower in cost, easier to provision and simpler to operate.
