In the cognition of many people, what is an optical module? Some people answered: it is not composed of an optoelectronic device, a PCB board and a housing, but what else does it do?
In fact, to be precise, the optical module is composed of three parts: optoelectronic devices (TOSA, ROSA, BOSA), optical interface (housing) and PCB board. Secondly, its function is to convert the electrical signal into an optical signal from the transmitting end. After transmitting through the optical fiber, the receiving end converts the optical signal into an electrical signal, which is simply an electronic component for photoelectric conversion.
But perhaps you did not expect that the application range of optical fiber modules is so wide. Today, ETU-LINK will talk to you about which range and equipment the optical fiber modules are used in.
First of all, optical fiber modules are mainly used in the following equipment:
1. Optical fiber transceiver
This optical fiber transceiver uses 1*9 and SFP optical modules, which are mainly used in corporate intranets, Internet cafes, IP-hotels, residential areas and other fields, and the application range is relatively wide. At the same time, our company not only sells optical modules, cables, jumpers and other products, but also prepares some ancillary products, such as transceivers, pigtails, adapters and so on.
2. Switch
Switch (English: Switch, meaning “switch”) is a network device used for electrical signal forwarding, mainly using electrical ports, 1*9, SFP, SFP+, XFP optical modules, etc.
It can provide an exclusive electrical signal path for any two network nodes connected to the switch. Among them, the most common switches are Ethernet switches, followed by telephone voice switches, optical fiber switches, etc., and we have more than 50 brand switches. The optical modules will be tested for compatibility with real devices before they leave the factory, so the quality is high. You can rest assured.
3. Optical fiber network card
Fiber optic network card is a fiber optic Ethernet adapter, so it is referred to as fiber optic network card, mainly using 1*9 optical module, SFP optical module, SFP+ optical module, etc.
According to the transmission rate, it can be divided into 100Mbps, 1Gbps, 10Gbps, according to the motherboard socket type can be divided into PCI, PCI-X, PCI-E (x1/x4/x8/x16), etc., according to the interface type is divided into LC, SC, FC , ST, etc.
4. Optical fiber high-speed ball machine
The fiber optic high-speed dome mainly uses SFP optical modules, and the high-speed dome, in simple terms, is an intelligent camera front end. It is the most complex and comprehensive performance camera front end of the monitoring system. The fiber optic high-speed dome is in the high-speed dome. Integrated network video server module or optical transceiver module.
5. Base station
The base station mainly uses SFP, SFP+, XFP, SFP28 optical modules. In the mobile communication system, the fixed part and the wireless part are connected, and the equipment is connected to the mobile station through wireless transmission in the air. With the advancement of the construction of 5G base stations, the optical module The industry has also entered a period of demand for production.
6. Optical fiber router
Optical fiber routers generally use SFP optical modules. The difference between it and ordinary routers is that the transmission medium is different. The network port of ordinary routers uses twisted pair as the transmission medium, and the network cable that it leads out is an electrical signal; while the network port of the optical fiber router It uses optical fiber, which can be used to analyze the optical signal in the home fiber.
Secondly, there are many applications of optical fiber modules, such as:
1. Railway system. In the communication system network of the railway system, the application of optical fiber communication technology always plays an important role. It can not only improve the efficiency of ordinary optical fiber communication, but also can enhance the efficiency of information utilization in the railway communication network by virtue of its good data transmission stability advantages.
2. Tunnel traffic monitoring. As the urbanization process continues to accelerate, the urban population’s travel is increasingly dependent on the subway. It is imperative to ensure the safety of the subway. The application of temperature-sensing optical fiber to subway tunnels can effectively play a role in fire warning. .
In addition, the application scope of optical modules is still in intelligent transportation systems, building automation, ISP network solution providers and automotive networks. Not only optical fibers can be used for communication transmission, but optical modules also save space and cost, and are convenient and quick. specialty.
At the same time, as the main pillar of modern information exchange, processing and transmission, the optical communication network has been continuously developing towards ultra-high frequency, ultra-high-speed and ultra-large capacity. The higher the transmission rate, the greater the capacity, and the cost of transmitting each information is getting smaller and smaller. In order to meet the requirements of modern communication equipment, optical fiber modules are also developing into highly integrated small packages. Low cost, low power consumption, high speed, long distance, and hot plugging are also its development trends.
