comparison between CWDM and DWDM

by www.fiber-mart.com CWDM, just as DWDM, use multiple light wavelengths to transmit signals over a single optical fiber. However, there are still some differences betwwen the two techologies in many ways.   CWDM uses a 20-nm wavelength spacing that is much wider than the 0.4 nm for DWDM. The wider [ Continue reading…]

Different Ports on WDM Mux/Demux

by www.fiber-mart.com In the WDM (wavelength-division multiplexing) system, CWDM (coarse wavelength-division multiplexing) and DWDM (dense wavelength-division multiplexing) Mux/Demux (multiplexer/demultiplexer) modules are often deployed to join multiple wavelengths onto a single fiber. Multiplexer is for combining signals together, while demultiplexer is for splitting signals apart. On a WDM Mux/Demux, there are many kinds [ Continue reading…]

Choose Duplex Fiber or MPO/MTP Fiber for 40G Solutions?

by www.fiber-mart.com There’s been a lot of talk lately surrounding bidirectional 40 Gb/s duplex applications, or BiDi for short. Currently offered as a solution by Cisco®, BiDi runs over duplex OM3 or OM4 multimode fiber using QSFP modules and wavelength division multiplexing (WDM) technology. It features two 20 Gb/s channels, [ Continue reading…]
