The optical module is mainly used in the field of data communication, and its function is to realize the transformation of photoelectric signals. Because of the rise of big data, blockchain, cloud computing, Internet of Things, artificial intelligence, and 5G, data traffic has increased rapidly, and the light of data centers and mobile communication has become a research hotspot in the optical communication industry. Next, you will introduce in detail which areas can the light module be applied in detail.
1. Data Center
A large number of network switches, server groups, etc. are placed in the main room of the data center. They are the core of comprehensive wiring and information network devices, and they are also data convergence of the information network system. The connection between the server, the connection between the switch, the connection between the server and the switch, the optical module (direct connection copper cable, active optical cable), optical fiber jump, and other transmission vectors need to be used to achieve data interoperability.
With the increasing demand for data transmission, IDC machine rooms can enhance the business competitiveness of small and medium -sized enterprises. The diversification of the interconnection scenarios of the data center and the personalization of customer needs have spawned different types of network devices and transmission carriers (with source optical cables, direct copper cables, optical modules, optical fiber jump lines). Therefore Or when accessories, you need to choose according to the actual application scenario.
2. Mobile communication base station
The operator's mobile communication base station also needs light modules to achieve interconnection between devices. The base station has RRU and BBU devices. In the application, we need to connect the links of these two devices. This requires our light module The fiber jumper is over. In the 4G network, the devices used for BBU and RRU are mainly 1.25G light modules, 2.5G light modules, 6G light modules, and 10G light modules.
Third, source wave division system
The passive wave division system is mainly used in the urban area network, backbone network, and wide area network. The CWDM light module and DWDM light module are commonly used. Among them, the CWDM optical module uses CWDM technology, which can reinstate the optical signal of different wavelengths through an external wavelength division and transmit it through a fiber to save fiber resources. At the same time, the receiving terminal needs to use the wave decomposition to decompose the compound signal.
The channel interval of the passive wave division reuse technology (CWDM) is 20nm, the working wavelength is 1270-1610Nm, and the CWDM light module of 40km and above is the rear wave (1470-1610Nm). The module uses a full band (1270-1610Nm).
The CWDM optical module is usually used in the CWDM system, which is lower than the cost of DWDM light module and is widely used. In a CWDM system, the CWDM light module is inserted in the switch, and the CWDM light module with the CWDM decomposer or OADM light is inserted into the connection with the jumper.
