In modern Internet era, optical transceiver modules and fiber network switches are indispensable for enterprise network deployment and data center construction. Optical transceiver modules are used for converting electrical signal and optical signal, while fiber network switches are used for electrical (optical) signal forwarding. Common optical transceiver modules include SFP, SFP+, XFP, SFP28, QSFP+ and QSFP28, among which SFP+ optical modules are the most widely used, connected with fiber network switch to realize different network requirements. https://www.glsun.com/article-p79-optical-transceiver-module-and-fiber-network-switch-matching-tips.html
