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 in different directions. But […]

How to Install and Connect CWDM System?
CWDM system is able to provide optical networking support for high-speed data communication for metropolitan area networks (MANs). And in some previous articles, I have talked a lot about CWDM, such as the components used in CWDM system. In this article, I’d like to have an introduction to CWDM system installation and connection. Procedures for […]
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 increases, 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 […]
CWDM & DWDM Mux/Demux Overview
As we all know, WDM (wavelength-division multiplexing) is a method of multiplexing a number of optical carrier signals onto a single optical fiber by using different wavelengths (colors) of laser light. It enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. In a WDM system, a multiplexer (Mux) is used […]
An Introduction of CWDM Fiber Optic Splice Tray
When we talk about CWDM Tray, it means the CWDM splcie tray but not the rack mount “CWDM Tray”. A CWDM splice tray is a fiber optic splice tray that can be integrated with CWDM components (e.g. CWDM MUX). The CWDM tray allows for easy integration in enclosures, wall-mount boxes, or Optical Distribution Frames (ODFs). […]
