4 Channels CWDM Mux or Demux, 1550-1610nm, with Expansion Port, 1.5dB Typical IL, LC/UPC, Single Fiber, FMU Plug-in Module

The 4CH Mux Demux, based on TFF technology, is a passive CWDM device featuring high density, low loss, and short-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, 1/2/4/8/16G 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.
