Tips for choosing optical fiber transceiver;
(1) See if it can 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, and it is in half-duplex mode, it will definitely cause serious collision and packet loss.
(2) See if it has been connected with other optical fiber connectors. At present, there are more and more optical fiber transceivers on the market. If the compatibility of different brands of transceivers is not tested in advance, packet loss, long transmission time and different speeds will also occur.
(3) See if it has a safety device to prevent packet loss, because many manufacturers often use register data transmission in order to reduce the cost when making optical fiber transceivers. The biggest disadvantage of this mode is that data transmission will be unstable, resulting in packet loss, and the best way is to adopt buffer circuit design, which can safely avoid data packet loss.
(4) See whether the product has passed the temperature test, because the optical fiber transceiver itself will generate high heat when used, and its installation environment is usually outdoor, so whether the optical fiber transceiver can work normally when the temperature is too high (not exceeding 50℃) is a very important factor that users need to consider! What is the maximum allowable working temperature? For a device that needs to run for a long time, this item deserves our attention!
(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, there will definitely be compatibility problems.
(6) Measure the after-sales service of manufacturers. Imagine if your equipment broke down and the manufacturer failed to solve the problem for several days, how much would your loss be? Therefore, in order to make the after-sales service timely and early response, I suggest you choose a professional company with strong strength, superb technical force and good reputation in the region. 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 whether the optical fiber module shell of the product is aging, shiny or worn. In order to make huge profits, many manufacturers use second-hand or old optical fiber modules in optical fiber transceivers, optical fiber switches and other equipment. Products using these second-hand optical fiber modules have caused great hidden dangers to network transmission. For example, the optical path of optical fiber modules is polluted, which will definitely affect signal transmission and reduce transmission quality. However, the decline of transmission quality will also reduce the sensitivity of reception and cause the phenomenon of packet loss. Coupled with the use of second-hand optical fiber modules, the service life will be discounted, and parts will fail at any time.
