What is an optical module? What kind of optical module is used in what scene?
Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. There are various optical modules on the market. Which optical modules are used in what scenarios?
The downstream optical modules are mainly used in three scenarios: telecom bearer network, access network, data center and Ethernet.
Both the telecom bearer network and the access network belong to the telecom operator market. Among them, wavelength division multiplexing (xWDM) optical modules are mainly used for medium and long-distance telecom bearer networks, and optical interconnects (Opitcal interconnects) are mainly used for backbone networks and long-distance core networks. Large-capacity transmission; and the access network market is the "last mile" from operators to users, including fiber-to-the-home passive optical networks (FTTH PON, PON optical modules currently have a maximum transmission rate of 10Gbs),
Wireless fronthaul (5G optical module, the current maximum transmission rate is 25Gbs) and other application scenarios.
The data center (above 40G) and Ethernet market mainly include scenarios such as data center interconnection, data center interconnection (DCI), and enterprise Ethernet (Ethernet).
