Comparing the advantages and disadvantages of the

Comparing the advantages and disadvantages of optical fiber transceivers, we know that these three purchases will not be fooled

the era of all light is no longer far away! First of all, we are no longer unfamiliar with networks. With the popularization of information technology and the growing maturity of communication technology, optical communication has become an inevitable trend to meet people's needs for communication networks. From the five kinds of cables in the industrialization of bio based chemical fibers to the use of optical fibers today, as an important link in the optical communication transmission process, do you know how to judge the advantages and disadvantages of products

today, I'll teach you how to choose a transceiver with guaranteed quality

(1) optical fiber transceiver is an active product, and its normal use should ensure continuous and normal power supply. Key words: power supply, power supply connector

high quality power supply is an important supporting component that directly protects the transceiver, so how to distinguish the quality of the power supply

first, the certified power supply with isolation and anti-interference should be used. The power supply with incomplete or nonstandard marks, specifications, models, power supply properties, rated power supply voltage range, etc. and incomplete information should be used with caution

second, good power adapters generally have a structure similar to that of polymer materials, which have a high elongation and are compact. They can be judged intuitively on the hand. Those with obviously light weight are likely to be Jerry built

finally, as an insignificant small role, the power connector often produces oxidation in lightning strikes, long working hours, etc. Cause failure, so you should also start with details when choosing suppliers to avoid the probability of failure caused by small mistakes as far as possible

(2) how to keep the operation stable during the use of optical fiber transceiver, without network blockage, packet switching, high and low temperature resistance and crash. Key words: chip, shell material selection, ventilation design

the core component of the transceiver is the chip, which is equivalent to the human brain. The speed and reliability of data processing directly affect its stability. When choosing a chip, we must insist on refusing to use second-hand chips and foreign garbage to ensure the reliability and stability of operation

in addition, the perforated shell with good ventilation performance should also be used in the design to ensure that the heat can be ventilated and dissipated in time. Now, in order to improve competitiveness, some manufacturers also use aluminum fins as an auxiliary, so as to increase the stability of products. The optical fiber transceiver itself will generate high heat when used, and the temperature is too high or too low, which is not conducive to the normal operation of the equipment (generally not higher than the ambient temperature: -30 ℃ - +75 ℃ storage temperature: -40 ℃ - +85 ℃). Is the optical fiber transceiver working normally? What is the maximum allowable working temperature? For equipment that needs long-term operation, this item is very worthy of our attention

(3) how to ensure the small attenuation of optical signals in the transmission of optical fiber transceivers and the non packet switching in the transmission of electrical signals, key words: optical modules, RJ45 connectors

new optical modules are used, and all accessories have passed the aging test. Second hand modules are resolutely not used

rj45 interface uses all metal components, and does not use inferior non whole body metal connectors, so as to avoid plastic cracking, loosening, short circuit, poor contact and other faults caused by use for a period of time
