Understanding Ports on CWDM MUX/DEMUX

WDM (Wavelength Division Multiplexing) is a commonly used technology in optical communications. CWDM and DWDM MUX/DEMUX are two important components in WDM systems, which are often deployed to join multiple wavelengths onto a single fiber. There are some ports on CWDM and DWDM MUX/DEMUX like channel port, line port, monitor port, etc. This article will focus on discussing the functions of ports on CWDM MUX/DEMUX. What is…

How to Identify the Fiber Patch Cord Color Code?

Fiber patch cord, often called fiber patch cable or fiber jumper, is a fiber optic cable terminated with fiber optic connectors (LC, SC, MTRJ, ST etc.) at each end. Fiber patch cord can be classified into various types based on different standards, such as fiber cable mode, transmission mode, jacket type, connector type, and polishing type. And fiber patch cord plays…

Copper SFP vs Fiber SFP – Which One is Better?

The battle between copper and fiber has raged for many years. Copper has been used for a long time while fiber has already established a niche in the industry. Someone even held that fiber might replace copper. This competition of copper and fiber also exists in the field of a transceiver module. Actually, there is a measurable distinction between copper SFP…

Fiber Optic Core-How Much Do You Know About It?

For anyone who wants to know fiber optic cable, it’s a must to know the structure of an optic fiber. An optical fiber consists of three basic parts: the core, cladding, and the coating layer outside the cladding. What is the Core of an Optical Fiber? An optical fiber core is a glass or plastic made cylinder running along the fiber’s…
