The 4CH Mux Demux, based on TFF technology, is a passive CWDM device featuring high density, low loss, and long-haul transmission suitability. It is integrated with an expansion port, which supports expanding the capacity of existing fibre infrastructure. It utilises 1550nm CWDM channels to transmit multiple DWDM wavelengths within a single CWDM channel, providing a cost-effective and easily scalable solution. In addition, this unit can act as a multiplexer or a de-multiplexer (Mux/Demux). It combines 4-channel of CWDM wavelengths into a composite signal or separates the combined CWDM signal into 4-channel individual wavelengths over a single-mode optical fibre. In accordance with the ITU-T G.694.2, it maximises the capacity of the C-band range. Designed for maximum configuration flexibility, the CWDM Mux Demux can plug directly into the FMU chassis, each module occupying one slot.
It supports 1G/10G/25G Ethernet, SDH/SONET, 16/8/4/2/1G Fiber Channel, FTTx and CATV. When deployed with FS CWDM optical transceivers, OEO and OADM modules, it seamlessly enables flexible network architectures ranging from simple point-to-point connections to amplified ring configurations.
