How to choose an industrial-grade fiber optic transceiver?


In the actual purchase of industrial optical transceivers, one of the important factors is the price. We believe that a few hundred yuan of products is enough to meet the needs of general enterprises, unless it is a special industry, such as telecommunications, military and so on. Of course, in addition to the price, it is also necessary to consider the compatibility of the product with the surrounding environment and the stability and reliability of the product itself. Otherwise, no matter how low the price is, it is useless to buy it. In order to purchase suitable products, we list the purchasing points of industrial-grade optical fiber transceivers as follows:

(1) Can it support full-duplex and half-duplex, because some chips on the market can only use full-duplex environment and cannot support half-duplex. If it is connected to other brands of switches (N-way switches) or hubs (hubs), using half-duplex mode will definitely cause serious collisions and packet loss.

(2) Whether it has been tested with other optical fiber connectors. There are more and more fiber optic transceivers on the market. If the compatibility of different brands of transceivers is not tested in advance, there will be packet loss, long transmission time, and different speeds.

(3) Is there a safety device to prevent packet loss, because many manufacturers often use the register data transmission method to reduce costs when making fiber optic transceivers. The biggest disadvantage of this mode is that data transmission will be unstable, resulting in packet loss. The best way is to use a buffer circuit design, which can safely avoid packet loss.

(4) Whether the product has been temperature tested. Because the fiber optic transceiver itself will generate high heat during use, and the installation environment is usually outdoors, the user needs to consider whether the fiber optic transceiver can work normally when the temperature is too high (not more than 50°C). A very important factor! What is the maximum allowable operating temperature of an industrial-grade fiber optic transceiver? For a long-running device, this is very concerning!

(5) Does the product conform to the IEEE802.3 standard? If the optical fiber transceiver conforms to the IEEE802.3 standard, if it does not conform to this standard, there will definitely be compatibility problems.

(6) Measure the after-sales service of the manufacturer. Just imagine, if your equipment is broken and the manufacturer has not solved the problem for a few days, how much will your loss be? Therefore, in order to enable the after-sales service to respond in a timely and early manner, we recommend that you choose a company with strong strength and superb technical force. , a professional company with a good reputation in the local area. Only the technical engineers of professional companies have rich troubleshooting experience and advanced fault detection tools!

(7) When purchasing, carefully observe the appearance of the product to see if the fiber optic module shell of the product is aging, shiny or worn. Now many manufacturers in the market use second-hand or old equipment on fiber optic transceivers, fiber optic switches and other equipment to make huge profits. The products of these second-hand fiber optic modules cause great hidden dangers to network transmission. For example, the optical path pollution of the fiber optic module will definitely affect the signal transmission and reduce the transmission quality, but the decrease in the transmission quality will also reduce the receiving sensitivity. , which will also cause packet loss. Coupled with the use of second-hand optical fiber modules, the service life will be reduced, and parts will fail at any time.
