Guide about CWDM optical transceiver module
With the continuous development of the optical communication industry, CWDM optical modules are widely used in Gigabit Ethernet and Fibre Channel applications as a highly economical network connection solution. This article will focus on CWDM optical transceiver module .
Introduction
The CWDM optical transceiver module is a fiber optic transceiver module that combines CWDM technology. Which can be used in conjunction with a wavelength division multiplexer(WDM). uses a multiplexer to make the signals togethe at the transmitter, and a demultiplexer to split the signals apart at the receiver, Therefore, CWDM optical transceiver modules are known as a cost-effective network solution.
The classifications of CWDM optical transceiver module
CWDM optical transceiver modules can be classified into CWDM SFP optical modules, CWDM SFP+ optical modules, CWDM XFP optical modules, CWDM X2 optical modules, and CWDM LX-4 optical modules.
CWDM SFP optical transceiver modules combine the space savings of SFF and the flexibility of GBICs with the low power consumption of SFP optical modules, while meeting the functional and dimensional advantages, mainly used in Gigabit Ethernet and 2.5 Gbps SONET.
CWDM 10G optical transceiver modules include CWDM SFP+ optical modules, CWDM XFP optical modules, CWDM X2 optical modules and CWDM LX-4 optical modules.
The IEEE Association has developed a CWDM standard for the design of these high-rate devices. IEEE 802.3 AE-2002, so CWDM 10G optical transceiver modules can reach longer transmission distances at 10 Gbps.
