Single-Fiber CWDM MUX/DEMUX Analysis

Dual-fiber CWDM MUX/DEMUX is typically used in CWDM network to achieve dual way transmission, which transmits and receives signals with the same wavelength. A duplex fiber links two dual-fiber CWDM MUX/DEMUXs, supporting the same wavelengths installed on each end of the optical network. Two fibers with the same wavelength enable duplex transmission on different directions. […]

Introduction to the Components Used in CWDM System

CWDM system is a passive optical solution for increasing the flexibility and capacity of existing fiber lines in high-speed networks. It increases fiber capacity by placing widely spaced, separate wavelengths (between 1310 nm and 1610 nm) from multiple ports onto a single-mode fiber pair on the network. The CWDM system components are passive and require […]

Traditional CWDM Mux/DeMux vs. FMU Series CWDM Mux/DeMux

With the need for bandwidth increasing, the WDM (wavelength division multiplexing) technology was developed to expand network capacity over a single fiber. It uses a multiplexer (Mux) at the transmitter to combine several signals together, and a demultiplexer (DeMux) at the receiver to split them apart. Most WDM systems operate on 9µm single-mode fiber optical […]
