interfacing The Finisar MUX/DEMUX-4-EX plug-in module is a passive optical
multiplexer/demultiplexer designed for metro access applications that represents the
state of the art in fiber optics design. The MUX/DEMUX-4-EX plug-in module
multiplexes and demu ltiplexes four CWDM wavelen gth chann els from a t wo-fiber circui t
and passes the other channels. Finisar’s design allows the creation of cost-effective
unidirectional network traffic rings or point-to- point links.
Multiplexed wavelengths are interfaced to any of Finisar’s CWDM transceivers on the
equipment side. A grid of eight CW DM wavelengths is available from Finisar.
The MUX/DEMUX-4-EX plug-in module plugs into one half of a 1RU, 19” rack mount
chassis for simple installation and modularity. This Chassis based system allows
network equipment manufacturers to add WDM capability to any existing network
device than supports GBIC and SFP interfaces.
Each equipment port of the MUX/DEMUX- 4-EX plug-in modu le is color coded to match
the wavelength of Finisar’s CWDM transceiver. This allows ease of installation and
troubleshooting without having to remove the transceiver from the local equipm ent.
The Finisar MUX/DEMUX 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.
