A router is a hardware device that connects two or more networks. It acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. Routers can be divided into backbone routers (core routers), enterprise-level routers, and access-level routers.

Generally, backbone routers have multiple optical ports. Take H3C CR series core routers as an example. The port types of H3C CR series core routers are SFP, SFP+, XFP, QSFP+, CFP2, QSFP28 optical interfaces, which can be matched with 1.25G SFP series optical modules. , 10G SFP+ series optical modules, 40G QSFP+ series optical modules, 100G QSFP28 series optical modules, etc. Below, ETU-LINK will give you some examples of commonly used optical module types.

The optical modules listed in the above table are relatively common optical modules. Among them, multi-mode optical modules can be equipped with multi-mode patch cord, and single-mode optical modules can be equipped with OS2 single-mode patch cord.

Enterprise routers are mainly used to connect enterprise LANs and WANs. Its advantage is that it is suitable for large-scale enterprise network connections. It can adopt complex network topologies, load sharing and optimal paths, and can better handle multimedia with high security; The bandwidth of the local area network isolates unnecessary traffic and reduces the burden on the host. H3C enterprise-class router interfaces are mainly network ports. The access-level routers are mainly used to connect small business customers in homes or ISPs, and their main interface types are network ports. ETU-LINK can provide optical modules of various specifications that are compatible with H3C equipment. All optical module products have passed the real machine test to ensure compatibility and undergo a number of high-quality tests to ensure their stability before shipment. Users provide system solutions to help users build a stable network with low cost, high efficiency and easy management.
