We should know the nine common senses of optical transceivers.

First, what is the main purpose of the optical transceiver and the market price?

Simply put, the optical transceiver mainly transmits optical signals and is a kind of optical communication equipment.

The market price of optical transceivers is not to say that a price can be reported casually. There are thousands to tens of thousands or even hundreds of thousands of optical transceivers on the market, and optical transceivers are used in pairs. Optical transceiver products from different manufacturers are not universal at present; Therefore, the price of the optical transceiver, according to the customer's application environment, transmission purposes, targeted configuration of optical transceivers, the price of different configurations of optical transceivers vary greatly.

Second, the difference between optical transceivers and protocol converters?

The Ethernet converter is also called the protocol converter, and the protocol converter is also called the gateway. Xiaobo remembers that the three devices refer to the same type of device, which enables the hosts on the communication network to adopt different high-level protocols to cooperate with each other to complete various kinds of devices. Distributed application. It works on the transport layer or higher.

The optical transceiver is a device that converts multiple E1 (a data transmission standard of a trunk line, usually at a rate of 2.048 Mbps, which is adopted in China and Europe) into an optical signal and transmits it.

The biggest difference is that the Ethernet converter is a protocol conversion device, and the optical transceiver is a photoelectric conversion device.

Third, how to use PFM modulation technology for optical transceiver equipment?

The video optical transceiver is a device that converts one to more analog video signals into optical signals through optical fibers through various codes. Since the video signals are converted into optical signals, the analog conversion and digital conversion technologies are used. Video optical transceivers are further divided into analog optical transceivers and digital optical transceivers.

Fourth, in the optical transmission network, with a video optical transceiver, but also use a decoder?

The optical transceiver is used when the front camera is far away from the control center. It is divided into a transmitting end and a receiving end. The transmitting end converts the electrical signal transmitted by the camera into an optical signal and transmits it to the receiving end of the optical transceiver through the optical fiber, and the receiving end passes through the transmitting end. The optical signal transmitted from the optical fiber is reduced to an electrical signal. The principle is this.

Both video optical transceivers and video codecs are used for video transmission. The difference is that video optical transceivers are often uncompressed real-time transmissions, and codecs are often compressed and transmitted, and are not real-time. Demand. The data interface is generally a crimp terminal block. The E1 interface is generally a BNC or E1 card port. The fiber interface is generally FC or ST, and the FC is more. It is a dedicated interface for optical communication. With the video optical transceiver, no other need is required. It is set up, the console signal is connected to the optical transceiver, and the front-end optical transceiver is connected to the cloud platform to realize the control.

So, in summary, do you want to use the decoder, which is based on the use environment.

5. What role does the optical transceiver play in the security monitoring platform?

The role of the optical transceiver in security is mainly to play the role of the optical transceiver itself. The function of the optical transceiver is to convert some signals with relatively short transmission distances into signals with relatively long transmission distances. The main function is to increase the transmission distance and save costs in monitoring (multiple video signals can be used with one Optical fiber transmission).

Sixth, how to deal with the lack of light in the optical transceiver?

First, use the optical power meter to measure the light collection of the optical transceiver, see if the opposite end is illuminated, or use the fiber optic cable to self-loop the optical port of the device to see if there is any alarm; if the opposite end is not sent, it may be right. The problem of the end device or the optical fiber. If the self-loop device also has an alarm, it is that the device itself is faulty and needs to be replaced and returned to the factory for maintenance.

Shenzhen Tianbo has a perfect after-sales service system and strong technical support.

Seven, how to maintain the optical transceiver?

When the control signal of the gimbal is sent to the other end of the fiber-connected transmitter, the RD indicator is always on, or flashes following your operation, and the electrical connection is correct, but the camera control still does not work properly. , indicating that the transmitter has a problem and should be replaced. If the RD indicator is off, there may be a problem with the transmitter or a problem with the receiver. Contact the optical transceiver manufacturer for further guidance.

8. What is the relationship between optical transceivers and switches?

Generally, the 2M on the optical transceiver is connected to the transmission relay board on the switch, and there are dedicated connection heads at both ends. Some of them are welded by welding, and must be received and sent at both ends, and the general 2M line. In the middle of the cable is the transmission signal line, and the outer mesh line is the shielded line.

9. What is a digital video uncompressed optical transceiver?

The digital video uncompressed optical transceiver is developed on the basis of the original technology of the optical transceiver, and is used for more application environments in order to transmit longer distances.

The digital video uncompressed optical transceiver uses optical fiber as the transmission platform, which has several advantages that are unparalleled in the field of wired transmission: 1 fiber transmission frequency bandwidth, large capacity, can reach terahertz level; 2 low transmission loss, can reach 100 Kilometers without relay transmission; 3 is not an electrical conductor, is not subject to electromagnetic interference, and has excellent security and confidentiality; 4 is rich in fiber resources and belongs to non-metallic resources. A small reserve can save considerable repetitive construction costs.

The R&D and production of the domestic optical transceiver, a well-known manufacturer of optical transceivers, has continuously introduced new technologies and new concepts, keeping up with the development trend of the security industry, and its safety, functionality, practicability and stability have been greatly developed.
