SFP stands for “small form-factor pluggable.” SFP transceivers are compact and hot-pluggable devices that act as an interface between networking equipment (switch, router, network card) and interconnecting cabling (copper or fiber).
The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer.
When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.
The composite optical signal is decomposed at the receiving end using a wave decomposition multiplexer, thereby conserving fiber resources. Therefore, CWDM optical modules are called a low-cost and efficient network solution.
Secondly, the classification of CWDM optical modules
CWDM optical modules can be classified into CWDM SFF optical modules, CWDM SFP optical modules, CWDM GBIC optical modules, CWDM SFP+ optical modules, CWDM XFP optical modules, CWDM X2 optical modules, CWDMXENPAK optical modules, and CWDM LX-4 optical modules.
Third, CWDM optical module application field
CWDM optical modules are widely used in CATV (cable TV), FTTH (Fiber to the Home), 1G and 2G Fibre Channel, 100M and Gigabit Ethernet, Synchronous Optical Network SONET OC-3 (155Mbps), OC-12 (622Mbps) And OC-48 (2.488Gbps), security and protection systems.
Fourth, the advantages of CWDM optical modules
1. Data transmission is transparent;
2, large capacity, so that the huge bandwidth resources of fiber can be fully utilized;
3. CWDM technology greatly saves fiber resources and effectively reduces construction costs;
4. It has networking flexibility, stability and reliability;
5. Compatible with all-optical network switching to realize long-distance non-electrical relay transmission;
6. The simplification of the laser module reduces the size of the equipment and greatly saves the space of the equipment room;
7. The optical layer recovery has independence and can effectively protect data transmission;
8, low insertion loss, low polarization dependent loss
