FS 1x2 DWDM Red/Blue C-band Filter is a high-performance passive micro-optics device that leverages environmentally stable thin-film filter (TFF) technology to deliver exceptional wavelength management. FS R/B has three ports. One port is called the ”Common” port. The other two ports provide the conduit for the two wavelength bands. The two bands are the Blue band (1529.35 - 1541.55nm) and the Red band (1548.31 – 1560.81nm). One band goes thru the Reflect band leg, and the other band which requires the highest isolation goes thru the Pass band leg. It is characterised with wide passband, low insertion loss, high return loss, excellent environmental stability and high power handling capability. Designed for maximum configuration flexibility, this module can plug directly into the FMT managed chassis, each module occupying one slot.
The FS 1x2 DWDM Red/Blue C-band Filter offers versatile deployment options, functioning as both a high-efficiency band combiner and band splitter to meet diverse network requirements. As a combiner, the device intelligently merges the Blue and Red bands through the Common port, while as a splitter, it precisely separates composite signals from the Common port into their respective wavelength channels. This module can facilitate an integrated cost-effective and flexible optical layer solution by incorporating a variety of optical layer boards, such as OEO/EDFA/DCM/MUX/OSW/OLP, and can be applied to DWDM single-fibre/optical cable monitoring systems to separate or combine wavelength signals to meet the diverse needs of scenarios.
