What is Fiber Optic Patch Cord?

Fiber optic patch cord is also known as fiber optic patch cable and fiber optic jumper. It is always protected by a thick layer of sheath and used as a jumper wire to connect device and fiber optic cabling link. This passage intends to give a brief introduction to fiber optic patch cord, and let’s ...

An Introduction to WDM Technology

Wavelength-division Multiplexing Technology makes signals of various wavelengths transmitting over one fiber, which dramatically increase the transmission capacity. Here, let us read the article and get further understanding about the technology. Development Background As the development in the information-based society and rapid rise of the information industry, the demands for transmitting high-speed data, high-definition image ...

Cisco CWDM SFP Solution Overview

Cisco Coarse Wave Division Multiplexing (CWDM) solution has made scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services possible in their networks. This solution mainly combines several different CWDM SFPs (small form-factor pluggable) and a set of CWDM passive multiplexers/demultiplexers or OADMs (optical add-drop multiplexers) to enable flexible network services. This kind of solution is ...

Introduction to Wavelength-division Multiplexing

Wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using differentwavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. A WDM system uses a multiplexer at the transmitter to join the signals ...

WDM Technology Overview

Traditionally, each fiber connection requires two strands of fiber, one for TX and one for RX, namely, transmission and reception. What will you do when all of your installed fibers are used up and you need to add more links? Will you choose to install more fibers or to lease more fibers? Actually, you can ...

Introduction of Wavelength-Division Multiplexing

As the explosive growth of 4G users in China, the speeding up of broad service and the rapid development of tri-networks integration, optical communications industry has gained great development in recent years. And as one of the core products in this industry, the demands of WDM products are also increasingly growing. In fiber-optic communications, wavelength-division ...

Differences between CWDM and DWDM

Coarse Wavelength Division Multiplexing (CWDM) and Dense WaveLength Division Multiplexing (DWDM) are two kinds of wavelength-division multiplexing (WDM) which is a technology multiplexing a number of optical carrier signals onto a single optical fiber by using different wave lengths of laser light. Seeing from their development, DWDM came well before CWDM. DWDM appeared only after ...
