Data communication scenario: A large number of network switches, server clusters, etc. are placed in the host rooms of enterprise data centers and internet data centers. They are the core of comprehensive cabling and information network equipment, and also the data aggregation center of information network systems. The connection between servers, the connection between switches, and the connection between servers and switches need to use Optical module, optical fibers and other transmission carriers to achieve data interoperability.?

The connection between servers, the connection between switches, and the connection between servers and switches need to use Optical module, optical fibers and other transmission carriers to achieve data interoperability.

    Enterprises and large Internet companies are the main end customers of the datacom market, and large Internet companies usually purchase Optical module directly when building data centers.

    Telecom scenario: On the mobile access network side, the interconnection of RRU and BBU devices needs to rely on Optical module and fiber jumpers. The metropolitan access layer, convergence layer, core layer/provincial trunk line of the bearer network are used to realize the forward and middle back transmission of 5G services, and the devices at each layer mainly rely on Optical module to achieve interconnection.

    In fixed network optical communication, optical fiber access, Metropolitan area network and Backbone network all use Optical module to support high-speed connection. In order to save the use of optical fiber and cable in long-distance communication, Wavelength-division multiplexing (WDM) technology is commonly used. Therefore, CWDM Optical module and DWDM Optical module are widely used. Through external Wavelength-division multiplexing, optical signals of different wavelengths are combined together and transmitted through one fiber.
