Tips for the Selection and Use of Optical Transceivers

Selection and use of optical transceivers

The optical transceiver is composed of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving.

The optical transceiver can convert electrical signals into optical signals at the transmitting end through photoelectric conversion, and then convert the optical signals into electrical signals at the receiving end after being transmitted through optical fibers.

Any optical transceiver has two functions of sending and receiving, performing photoelectric conversion and electro-optical conversion, so that the optical transceivers are inseparable from the devices at both ends of the network.

Nowadays, there are often tens of thousands of devices in a data center. To realize the interconnection of these devices, optical transceivers are indispensable. Today, optical transceivers have become a segment of the data center.

With the wide range of optical transceivers, more and more customers have begun to pay attention to the stability and reliability of the transceivers themselves. There are three kinds of popular optical transceivers on the market now: original optical transceivers, second-hand optical transceivers and compatible optical transceivers.

As we all know, the price of original optical transceivers is very high, and many users can only stay away. As for second-hand optical transceivers, although the price is relatively low, the quality is not guaranteed, and packet loss often occurs after a period of use.

Therefore, many manufacturers have turned their attention to compatible optical transceivers. Indeed, when compatible optical transceivers are in use, their performance is almost the same as that of original optical transceivers, and the price is several times cheaper than original optical transceivers. This is also compatible with optical transceivers. The reason for the heat.

However, the products on the market are mixed, and many merchants are shoddy and confused, which makes the selection of optical transceivers difficult. The following will discuss the selection of optical transceivers in detail. The transceiver modules compatibility matrix provides a comprehensive overview of the compatibility between different transceiver transceivers, enabling users to ensure seamless integration and optimal performance within their network infrastructure.

1. The selection of optical transceivers

We cannot ignore optical transceivers market. First of all, the first question, is how do we distinguish between new optical transceiver transceivers and second-hand optical transceivers? Second-hand optical transceivers often lose packets after a period of use, which is caused by unstable optical power and reduced optical sensitivity.

If we have an optical power meter, we can take it out and test it to see if its optical power is consistent with the parameters on the data sheet. If the discrepancy is too large, it is a second-hand optical transceiver.

Then observe the after-sales use of the optical transceiver. The service life of a normal optical transceiver is 5 years. It is basically difficult to see the quality of the optical transceiver in the first year, but it can be seen in the second or third year of its use.

Secondly, it depends on the qsfp compatibility matrix between the optical transceiver and the device. Before purchasing, consumers need to communicate with the optical transceiver manufacturer to inform which brand of equipment they need to use.

Finally, we also need to see how the temperature adaptability of the optical transceiver is. The temperature generated by the optical transceiver itself during operation is not high.

However, its general working environment is in the computer room or on the switch. Too high or too low temperature will affect its optical power, optical sensitivity and other parameters.

Under normal circumstances, the temperature range of the China optical transceiver used is 0~70°C . If it is in an extremely cold or extremely hot environment, an industrial-grade -40~85°C optical transceiver is required.

2. The use of optical transceivers

If you find that the function of the optical transceiver fails during use, don't worry, check carefully and analyze the specific reasons.

Generally, there are two main types of optical transceiver function failures, namely, the failure of the transmitter and the failure of the receiver. The most common reasons are as follows:

The optical port of the optical transceiver is exposed to the environment, and the optical port is polluted by dust; the end face of the optical fiber connector used is polluted, and the optical port of the optical transceiver is polluted twice; the end face of the optical connector with pigtail is not used properly, and the end face is scratched, etc.; use Poor quality fiber optic connectors.

Therefore, after purchasing an optical transceiver correctly, you should also pay attention to the cleaning and protection of the optical transceiver during use. After normal use, it is recommended to plug the dust plug when not in use. Because if the optical contact is not clean, it may affect the signal quality, which may cause LINK problems and bit error problems.

Compatible Optical Transceiver Types

Equipment manufacturers of optical transceivers will encrypt their devices to varying degrees, also known as compatibility. transceivers of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical transceivers. Compatibility manufacturers need to conduct different compatibility adaptations on the optical transceivers. Whether or not they can perfectly solve compatibility issues is particularly important.
