Now there are no less than hundreds of brands and manufacturers of various fiber media converters in the market, so how to choose? In order to enable you to pick a good product, some of the procurement points are listed as follows:

 (1) See whether it can support the full-duplex and half-duplex because in the market some chips can only use the full-duplex environment but cannot support the half-duplex one. If connected to the switches of other brands (N-Way Switch) or concentrator (HUB), which in turn uses half-duplex mode, it will cause serious collision and packet loss.

 (2) See whether it is connected with other fiber optic connectors for the connection test. In the market, there is more and more fiber media converter s. If the compatibility of different brands’ converters has not done the test, it will also produce packet loss, too long transmission time, suddenly slow and quick phenomenon.

(3) See whether it has security devices to prevent packet loss, because of many manufacturers in the production of fiber media converter s, in order to reduce costs, often use register (Register) data transmission mode whose biggest drawback is that the data transmission will be unstable, resulting in packet loss. The best way is to use the buffer line design, which can safely avoid data packet loss.

(4) See whether the product has done a temperature test, because the f fiber media converter itself will produce high heat, coupled with its usual outdoor installation environment, so if the temperature is too high (not greater than 50 ° C), whether fiber media converters are in normal operation is a very important factor for the user to consider! What is the allowable maximum operating temperature? For the device which needs to run for a long time, this is worth our attention!

(5) See whether the product meets the IEEE802.3 standard? If not meeting the standard, then there will certainly be compatibility issues.

(6) Measure the manufacturers’ after-sales service. Imagine that if your equipment is broken and manufacturers do not solve the problem within a few days, how much is your loss ah? So in order to make a timely and early response of after-sales service, it is recommended that you choose the professional company with the strong strength, technical strength, and fine reputation in the local areas. And only the professional company's technical engineers can have more abundant experience to eliminate the fault and more advanced tools to detect fault!

 (7) When purchasing, carefully observe the appearance of the product and observe whether the product’s fiber module shell is old, whether it is glossy or whether it has the wear marks.

There are many manufacturers in the market today using second-hand or old fiber modules in fiber media converters, fiber switches, and other equipment in order to seek to profiteer. The use of these second-hand fiber optical module products has caused great risks for network transmission, such as fiber module's optical path is contaminated, the signal transmission must be affected, the transmission quality declines which has also caused the decline of the sensitivity of the reception and caused the phenomenon of data loss. Coupled with the use of second-hand fiber module, the service life will be discounted, which will cause the failure of parts and so on at any time.
