In the actual procurement, an important factor for enterprises to consider is the price. In addition to the price, they must also consider the compatibility of the product with the surrounding environment and the stability and reliability of the product itself. In order to enable you to choose good products, some purchasing points are listed as follows:

 (1) Check whether it can support full duplex and half duplex. Because some chips on the market can only use full duplex environment, but cannot support half duplex. If it is connected to another brand of Switch (N-way Switch or HUB) and it uses half duplex mode, it will certainly cause serious collision and packet loss.

 (2) See if it has been tested with other optical fiber joints. There are more and more optical fiber transceivers on the market. If the compatibility of different brands of transceivers has not been tested in advance, packet loss, transmission time is too long, rapid and slow, and other phenomena will occur.

 (3) Look at it for packet loss prevention safety device, because a lot of manufacturers in the production of fiber optic transceivers, in order to reduce costs, often using Register (Register) data transfer mode, the chief drawback of this approach, is the data transmission will be unstable, causing packet loss, and the best way is to use the buffer circuit design, is safe to avoid data packet loss.

(4) Check whether the product has been tested for temperature, because the optical fiber transceiver itself will produce high heat, coupled with its installation environment is usually outdoors, so when the temperature is too high (not greater than 50°C), whether the optical fiber transceiver can operate normally is a very important factor for the user to consider. What is the maximum allowable operating temperature? This is of great concern for equipment that needs to run for a long period of time.

 (5) Check whether the product conforms to IEEE802.3 standard? Fiber optic transceivers that comply with the IEEE802.3 standard, if not the standard, then there will certainly be compatibility issues.

 (6) Measure the manufacturer‘s after-sales service.

 (7) Carefully observe the appearance of the product when choosing and buying, to see whether the fiber module shell of the product is old, shiny or whether there are signs of wear. Nowadays, there are other manufacturers on the market for profiteering, such as optical transceiver, optical switch device using the secondhand or old fiber modules, use these second-hand optical module products, cause great hidden trouble to the network, such as: optical module optical path is polluted, the signal transmission is bound to be affected, the transmission quality. And the transmission quality decreases, the sensitivity of receiving also causes a decrease, will also cause the phenomenon of data packet loss. In addition to the use of second-hand fiber module, the service life will be discounted, at any time parts failure and other situations.
