Wavelength Management

The Finisar 1550/CWDM plug-in module is a passive optical multiplexer/demultiplexer designed to add CWDM wavelengths to an existing 1550nm backbone ring. The module multiplexes and demultiplexes a single 1550nm wavelength and five additional CWDM wavelengths in a two-fiber ring network.

"Finisar's UltraSpan® Raman is a 1RU rack-mountable intelligent amplifier. It can be operated as a fully independent stand-alone network element, and the network-ready hardware and software support SNMP communication protocol. The UltraSpan® Raman is qualified as Class 1M with respect to laser safety. The amplifier incorporates three parallel, nondependent eye safety mechanisms that shut down the amplifier in case of a fiber link disruption, including open connectors (both PC and APC) or broken fiber even at a distance of few tens of kilometers from the unit. This unique and comprehensive safety mechanism is extremely important due to the Raman amplifiers’ high output power. This amplifier is comprised of an intelligent Raman pump unit containing up to three 14xx nm semiconductor diode pump lasers, and full comprehensive electronic control. The pump unit provides up to 18 dB Raman gain for G.652 fiber (SMF), allowing a repeaterless link to be extended by up to 7 dB. Using patent pending technology, the Raman pump unit can operate in full automatic gain control (AGC) mode, thus allowing the Raman gain to be set with an accuracy of +/-0.7 dB."

The Finisar forty channel DWDM module is a passive optical multiplexer/demultiplexer designed for metro access applications that represent the state of the art in fiber optics design. This MUX/DEMUX module multiplexes and demultiplexes forty DWDM wavelengths of 100GHz channel spacing into a ring or point-to-point network.

The Finisar sixteen channel DWDM Plug-in module is a passive optical multiplexer designed for metro access applications that represent the state of the art in fiber optics design. This MUX module multiplexes sixteen DWDM wavelengths of 100GHz channel spacing into a ring or point-to-point network.

"The Finisar one channel DWDM plug-in module is a passive optical add/drop multiplexer designed for metro access applications that represent the state of the art in fiber optics design. Finisar's unique one channel DWDM design maps one pair of add/drop channels of same wavelength with 100GHz channel spacing into two-fiber paths, going in opposite directions into a network (east/west)."

The Finisar four channel DWDM Plug-in module is a passive optical add/drop multiplexer designed for metro access applications that represent the state-of-the-art in fiber optics design. Finisar’s four channel DWDM design maps four pairs of add/drop channels with 100GHz channel spacing into two-fiber paths, going in opposite directions into a network (east/west).

The Finisar four or eight channel DWDM Plug-in module is a passive optical multiplexer/demultiplexer designed for metro access applications that represent the state of the art in fiber optics design. These MUX/DEMUX modules multiplex and demultiplexe four or eight DWDM wavelengths of 100GHz channel spacing into two-fiber paths, going in opposite directions into a network (east/west).
