CWDM SFP

The CWDM SFP optical module is an optical module that uses CWDM technology, which is similar to conventional SFP modules and supports hot-swappable, and the CWDM SFP optical module can be plugged into the SFP port or slot of the switch or router to connect the port to the fiber optic network. CWDM SFP optical modules are widely used in peer-to-peer networks of Gigabit Ethernet and Fibre Channel network equipment in telecommunications and data centers. The CWDM SFP optical module is a multi-rate optical module with a transmission distance of 20-40km, 40-80km and 80-120km, with different color markers of different wavelengths of lightc cables for more practical.

CWDM Introduction

CWDM (Coarse Wavelength Division Multiplexing) is a low-cost WDM transmission technology for the metro network access layer. In principle, CWDM is the use of optical multiplexers to multiplex different wavelengths of optical signals to a single fiber transmission, in the receiving end of the link, with the help of optical duplex to break down the mixed signal in the fiber into different wavelengths of the signal, connected to the corresponding receiving equipment. The main difference with DWDM is that the CWDM has a wider wavelength interval than the 0.2nm to 1.2nm wavelength interval in the DWDM system, with the industry-wide standard wavelength interval of 20nm.

SFP Transceivers

The SFP optical module is a hot-swappable small package module in the SFP package, with an interface for LC. The SFP optical module is mainly composed of lasers. SFP classification can be divided into rate classification, wavelength classification, pattern classification. CWDM SFP is a low-cost WDM transmission technology for metro network access layers. CWDM SFP optical module using CWDM technology, through the external wave division multiplexer, the different wavelengths of optical signals together, through an optical fiber transmission, thereby saving fiber resources. CWDM provides different speeds of protocol-transparent transmission channels on a single fiber.

In principle, CWDM is the use of optical multiplexers to multiplex different wavelengths of optical signals to a single fiber transmission, in the receiving end of the link, with the help of optical duplex to break down the mixed signal in the fiber into different wavelengths of the signal, connected to the corresponding receiving equipment. The CWDM optical module is an optical module using CWDM technology for connecting existing network equipment to CWDM multiplexers/de-multiplexers.

When used with the CWDM multiplexer/de-multiplexer, the CWDM optical module can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270nm to 1610nm) over the same single fiber.
