4-Channel Coarse Wavelength Division Multiplexer (CWDM)

The multiplexer is specially designed for line monitoring in WDM networks, access networks, metropolitan networks (MAN), cellular application, fiber optic amplifiers and telecommunication systems. This 4-channel CWDM enables a dual fiber strand to support multiple network topologies and data rates to exponentially increase bandwidth capacity.

It also allows for great flexibility by increasing the capacity of existing fiber infrastructure eliminating the need to lay new fiber at full capacity locations. Since the wavelengths are relatively far apart compared with DWDM, the CWDM is envisaged as a cost-effective solution for Metro Access and Metro Core/Regional network environments where more emphasis is on the network nodes with fairly short spans. Encapsulated within a non-flux metal bonding micro optic case, the multiplexer performs stably even in demanding environments.
