CWDM and WDM Applications Coarse Wave Division Multiplexing (CWDM) CWDM is a simple and affordable method to maximize existing fiber by decreasing the channel spacing between wavelengths. The benefits of CWDM include: • Passive equipment that uses no electrical power • Extended Temperature Range (0˚C - 70˚C) • Lower cost per channel than DWDM • Scalability to grow fiber capacity with little or no increased cost • Protocol transparent • Simple to install and use Since CWDM is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10 Gbps Ethernet at 1590nm). Because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed, CWDM can help to future proof the networking infrastructure. Another benefit to the passive CWDM technology is that no configuration is necessary, which makes CWDM a low-cost and effortless technology to implement. The most complex step in CWDM integration is aligning and connecting the patch cables from the correct wavelength optic to the correct port on the multiplexers on each end of the link. BWDM Transition Networks offers a variety of products with bi-directional optics, which accommodate bi-directional SFPs, to double your fiber capacity. Typically a BWDM deployment will use the 1310nm and 1550nm wavelengths. BWDM products are deployed in pairs to ensure the TX and RX of each device are not using the same wavelengths. In the example below, the multiplexers could be Ethernet, DS1 - T1/E1, DS3 - T3/E3, or any other protocol.
