The optical module is composed of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of the optical module is photoelectric conversion. The sending end converts the electrical signal into an optical signal. After transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal. Now, the optical module is getting more and more attention in the communication operation department, and the SFP optical fiber module is the most popular one among the modules.
As an optical module supplier, we are pleased to explain the definition of optical module: SFP optical fiber module The packaging form of SFP optical module is a hot-swappable small package. At present, the highest rate can reach 10G, and there are many LC interfaces. SFP can be simply understood as an upgraded version of GBIC. The size of the SFP optical fiber module is half that of the GBIC optical module, and more than double the number of ports can be configured on the same panel.
Composition of optical module: SFP optical fiber module is composed of laser, circuit board IC and external accessories. External accessories include shell, unlocking piece, buckle, base, pull ring, rubber plug, PCBA, and the color of the tab can help you identify the parameter type of the module.
The development of SFP optical fiber module: GBIC and SFF are in the optical module, and with the rapid development of the network, it is gradually replaced by the SFP optical module. It is developing in the direction of miniaturization and hot plugging. The SFP optical module inherits the hot-swappable feature of GBIC and also draws on the advantages of SFF miniaturization. The use of LC headers greatly increases the port density of network equipment, adapts to the trend of rapid network development, and has been widely used. Although many higher-tech and newer optical transceiver products have appeared, SFP optical transceivers will continue to exist for a long time. After SFP, the development of optical modules is mainly towards higher speeds, and now 10G, 40G, 100G and other optical modules have appeared. 100G optical modules are high-speed transceivers that use optical signals to transmit data over short and long distances in data centers and other networking environments.
Improper operation of the module during use can easily cause the failure of the optical module. In this case, don't worry, check carefully and analyze the specific reasons. Generally, there are two main types of SFP optical fiber module failures, namely, the failure of the transmitting end and the failure of the receiving end. The most common reasons mainly include the following aspects:
1. The end face of the optical fiber connector used has been polluted, resulting in secondary pollution of the optical port of the optical module;
2. The optical port of the optical module is exposed to the environment, and dust enters to pollute it;
3. Use inferior fiber optic connectors, etc.
The transceiver modules compatibility matrix is a helpful tool for ensuring that the transceiver modules selected for a network are compatible with the specific hardware and software components being used.
Therefore, pay attention to the cleaning and protection of the SFP optical fiber module in daily use. After use, it is recommended to plug the dust plug. Because the optical contact of the module is not clean, it is likely to affect the signal quality, which may lead to line problems and bit errors.
