It turns out that the application of fiber optic modules is so widely used?

In the cognition of many people, what is an optical module? Someone replied: it is not composed of an optoelectronic device, a PCB board and a shell, but what role does it have?

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 by the sending end, and after transmission 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 what you didn't expect is that the application range of fiber optic modules is so wide. Today, ETU-LINK will talk to you about the scope and equipment that fiber optic modules are used in.

First of all, fiber optic modules are mainly used in the following equipment:

1. Optical fiber transceiver;

This fiber optic transceiver adopts 1*9 and SFP optical modules, which are mainly used in enterprise 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 supporting products, such as transceivers, pigtails, adapters and so on.

2. Switch;

A 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 of the access switch. Among them, the most common switches are Ethernet switches, followed by telephone voice switches, optical switches, etc., and we have more than 50 brand switches in Yitian. The optical modules will be tested for compatibility with real devices before leaving the factory, so the quality is high. You can be absolutely assured.

3. Optical fiber network card;

The fiber optic network card is an optical fiber Ethernet adapter, so it is referred to as a fiber optic network card. It mainly uses 1*9 optical modules, SFP optical modules, SFP+ optical modules, etc.

It can be divided into 100Mbps, 1Gbps, 10Gbps according to the transmission rate, PCI, PCI-X, PCI-E (x1/x4/x8/x16), etc. according to the motherboard socket type, LC, SC, FC according to the interface type , ST, etc.

4. Optical fiber high-speed ball machine;

The optical fiber high-speed dome mainly uses SFP optical modules, and the high-speed dome is simply an intelligent camera front-end. 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 production demand.

6. Optical fiber router;

Optical fiber routers generally use SFP optical modules. The difference between them and ordinary routers is that the transmission medium is different. The network port of ordinary routers uses twisted pair cables as the transmission medium, and the network cables it leads are electrical signals; while the network ports of fiber optic routers It is the use of optical fiber, which can be used to analyze the optical signal in the home optical fiber.
