What is an optical fiber transceiver?
Question 1: What is an optical transceiver? Hello, optical fiber transceiver is a small intelligent device, which extends the transmission of network signals (Ethernet data) through optical fiber. It is plug-and-play and does not need to be set.

The popular name in the industry is also photoelectric converter. But there are essential differences between optical fiber transceiver and photoelectric converter. Optical fiber transceiver refers to the extended transmission of Ethernet signals. Photoelectric converter refers to the mutual conversion between optical signals and electrical signals.

Two optical fiber transceivers must be used together.

Divided into 100M and Gigabit, and also divided into single fiber and double fiber. Regardless of single fiber and double fiber, the conventional transmission distance is 25km. For more knowledge of optical fiber transceiver, you can also search for "Guangzhou Optical Communication". They specialize in producing communication equipment.

I hope my answer can help you! Wish you all the best.

Question 2: What is the main purpose of optical fiber transceiver? Electrical signals can be converted into optical signals and optical signals can be converted into electrical signals. For example, you have a computer somewhere and a computer in another city. If you want to connect these two computers to the internet, it is definitely not possible to use a network cable. You can connect them with the optical fiber transceiver on the optical cable side. One end of the transceiver is connected to the network cable to connect to your computer, and the other end is connected to the optical fiber transceiver at the other end of the optical cable, which is a computer in another city. You can connect to the Internet! A little simple, but it should be easy to understand!

Question 3: What is the function of optical fiber transceiver? Optical fiber transceiver is a small box, which converts optical signals in optical fiber transmission medium into electrical signals transmitted in network cables.

When you say10m/100m/1000m, you mean its transmission rate. How many megabytes, tens and hundreds of megabytes can be transmitted per second, or10/00 megabytes are all adaptive. At the beginning of the connection, we will negotiate with the peer device, and the peer is ten megabytes. Take the highest speed at which both parties can communicate.

The difference between optical fiber transceiver and switch. . .

A switch is a device that connects multiple terminal devices (computers, servers, etc.). ), multiple ports access multiple terminals at the same time.

Optical fiber transceiver has only one optical fiber port and one network cable port. It can be regarded as the middle section of the network cable, which is used to convert digital signals transmitted in two different media: optical fiber and network cable.

Question 4: What are the classifications of optical fiber transceivers? Introduction of various optical fiber interface types

fibre optic splice

FC: Round thread (most commonly used in distribution frames)

ST: snap-in circle

SC: Card Square (most commonly used in router switches)

PC: micro-spherical grinding and polishing

APC: The angle is 8 degrees, polished with microspheres.

MT-RJ: square, single-ended dual-fiber transceiver (useful on Huawei 8850) Optical fiber module: generally supports hot plug.

GBIC gigabit rate interface converter, the optical fiber interface used is mostly SC or ST type, SFP small package GBIC, and the optical fiber used is LC type.

Optical fiber transceiver is also composed of various components, so the diversity of components leads to the diversity of transceiver varieties.

Optical fiber used:

Single mode: L, wavelength 13 10 Single mode long-distance LH wavelength 13 10, 1550.

Multi-mode: SM wavelength 850

When using optical fiber transceiver to connect different devices, be sure to pay attention to the different ports used.

1. Connection between optical fiber transceiver and 100BASE-TX equipment (switch, hub): ensure that the length of twisted pair does not exceed100m;

Connect one end of the twisted pair to the RJ-45 port (upstream port) of the optical transceiver, and the other end to the RJ-45 port (public port) of 100BASE-TX.

2. Connection between optical fiber transceiver and 100BASE-TX equipment (network card): ensure that the length of twisted pair does not exceed100m;

Connect one end of twisted pair to RJ-45 port of optical transceiver (100BASE-TX port) and the other end to RJ-45 port of network card.

3. Connection between optical fiber transceiver and 100BASE-FX:

Confirm that the length of optical fiber does not exceed the distance range that the equipment can provide;

One end of the optical fiber is connected to the SC/FC/ST connector of the optical transceiver, and the other end is connected to the SC/ST connector of 100BASE-FX equipment.

Question 5: What is a plug-in optical fiber transceiver? In other words, there is a transceiver at the central end.

Chassis, there are many holes in the chassis, and then there are transceivers, each hole corresponds to a board, so that each board corresponds to a transceiver in the previous section to complete point-to-point link connection.

Question 6: What are the functions of switches and optical terminals? The difference between an optical switch and an optical transceiver is that:

1, optical fiber switch is a kind of high-speed network transmission relay equipment. Compared with ordinary switches, it uses optical cable as transmission medium. The advantages of optical fiber transmission are high speed and strong anti-interference ability;

2. Optical fiber transceiver is an Ethernet transmission medium conversion unit used to exchange short-distance twisted pair electrical signals and long-distance optical signals, also called optical fiber converter); In many places;

3. The optical fiber switch is connected with the server network, the 8-port optical fiber switch or the internal components of the SAN network through the optical fiber channel with high transmission rate, which makes the whole storage network have a very wide bandwidth and provides a guarantee for high-performance data storage;

4. Optical fiber transceiver provides ultra-low delay data transmission and is completely transparent to network protocols. Realization of data line speed forwarding with special ASIC chip. Programmable ASIC integrates multiple functions on one chip, which has the advantages of simple design, high reliability and low power consumption, and can make the equipment obtain higher performance and lower cost.

Question 7: What's the difference between an optical terminal and an optical module? Optical transceiver is mainly connected with optical fiber. Optical transceiver converts optical signals, and router performs NAT conversion between internal and external networks.

Question 8: What is the difference between optical fiber transceiver and optical transceiver? Similarity: photoelectric conversion is needed.

Difference: the transceiver only performs photoelectric conversion, does not change the code, and does not do other data processing. The transceiver runs the Ethernet 802.3 protocol and is only used for point-to-point connections.

Besides photoelectric conversion, optical transceiver also needs to multiplex and demultiplex data signals. Usually, the optical transceiver comes from E 1 line, and SDH and PDH optical transceiver are mainly used for telecom operators to provide multi-point-to-point data circuits. Video optical transceiver is mainly used in security monitoring, distance education, video conferencing and other fields that require high real-time video transmission. At the same time, it can transmit control, switch, language, Ethernet and other signals to meet the needs of multi-service applications, so we sometimes call it integrated optical transceiver. The optical fiber transceiver and optical transceiver that can be found on the Internet should be able to meet the energy demand, and I hope it can help you.

Question 9: What's the difference between an optical fiber transceiver and an optical cat? The so-called optical cat refers to a transceiver that converts optical Ethernet signals into signals of other protocols. Optical cat is the common name of optical modem, which has the function of modulation and demodulation. Optical cat, also known as single-port optical transceiver, is a product designed for special user environment. It uses a pair of optical fibers for single E 1 or single V.35 or single 10BaseT point-to-point optical transmission terminal equipment. As the relay transmission equipment of local network, this equipment is suitable for optical fiber terminal transmission equipment and private line equipment of base station. For multi-port optical terminals, they are generally called "optical terminals", and for single-port optical terminals, they are generally used at the user end. Their working principles are similar to those of baseband modems commonly used in WAN private line (circuit) networking, and some of them are called "optical modems", "optical cats" and "optical modems". Some people often mistake optical fiber transceiver or photoelectric converter for optical cat, which is actually a wrong name.

Optical fiber transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pair electrical signals with long-distance optical signals, and is also called optical fiber converter in many places. Products are generally used in the actual network environment where Ethernet cables cannot cover and optical fibers must be used to extend the transmission distance, and are usually located in the access layer of broadband metropolitan area networks. At the same time, it also plays a great role in helping to connect the last mile optical fiber line to metropolitan area network and external network.

Question 10: What is the difference between an optical module and an optical transceiver? The English name of optical transceiver is optical transceiver, which is an important device in optical communication system. These products are mostly used in the backbone of optical fiber networks. For example, if you open an Internet cafe and want to rent the bandwidth of 10M from an operator (such as telecom), they will pull the optical cable from the telecom data room to your Internet cafe, and then connect the optical fiber transceivers at both ends, and the other two ends of the transceiver are connected with network cables, which are respectively connected to the data room of your Internet cafe and the switch or router, so you can distribute the network cable to each machine through the switch. To put it bluntly, it is the equipment to extend the network cable. Generally, there are not many single-mode devices above 20KM, 25KM, 40KM and 60KM, and there is generally not much demand for ultra-long distance. At present, 10/ 100M adaptation is widely used, and 1000M adaptation is also available, but it is not widely used in many occasions. Multimode is rarely used now, and the cost of single-mode optical cable is not more expensive than multimode, which is generally within 2 kilometers. Transceivers are also divided into internal and external power supply, optical port single fiber and double fiber, centralized and single fiber type. In short, it is to choose according to customer needs and occasions. At present, the quality of products on the market is mixed and chaotic. As you said, laying optical fiber at a distance of 300 meters can satisfy both of them. . . It's up to you.
