An important factor in the actual procurement, enterprises consider price, especially small and medium enterprises and SOHO office. We believe that a few hundred dollars of products sufficient to meet the general needs of enterprises, except for special industries such as telecommunications, military and so on. Of course, in addition to price, but also must consider the product with the surrounding environment compatibility with and the product itself, the stability, reliability, otherwise the price is low, buy also no use. In order to be able to pick a good product, and to procurement points are listed below:
(1) if it can support full-duplex and half duplex, because some chips of the market, using the full-duplex environment, can not support half-duplex, connected to the other brands of switches (N-Way Switch) or hub (HUB), using half-duplex mode, will result in a serious collision and packet loss.
(2) whether it is done connection test with other fiber optic connectors, currently available fiber media converter more and more, such as the mutual compatibility of the different brands of the fiber converter not done in advance of the test also have lost packet transmission time is too long, suddenly fast suddenly slow phenomenon.
(3) whether it has to prevent loss of safety devices, many manufacturers in the production of fiber media converter, in order to reduce costs, often using the register data transfer mode, the greatest disadvantage of this way, data transmission instability, resulting in packet loss, and the best way is to use a buffer circuit design, safe to avoid data loss.
(4)whether the product has to do temperature testing, fiber media converter used to produce high fever, coupled with the installation environment is usually outdoors, so the temperature is too high (not greater than 50 ° C), fiber media converter whether the normal operation, users are very important factors to be considered! The maximum allowable operating temperature is how much? This very worthy of our attention to the needs of long-running equipment.
(5)whether the product is in compliance with IEEE802.3 standards? Such as fiber media converters comply with IEEE802.3 standard, if you do not meet the standard, then certainly there will be compatibility issues.
(6) to assess the manufacturer’s service, Imagine if your equipment is broken, the factory a few days do not solve the problem, your loss is how much. Therefore, in order to make after-sales service timely early response, it is recommended to select the region has superb strength, technical strength, reputable professional company. Only the more experienced professional technical engineers to troubleshoot and detect failures of the more advanced tools
(7) When you purchase carefully observe the appearance of the product, take a look at the fiber module shell whether old, whether shiny or whether the signs of wear. On the market today in order to reap huge profits, many manufacturers use in fiber media converters, optical switches and other equipment used or old fiber optic module, the use of these second-hand fiber-optic module products, caused a great deal of hidden network transmission, such as: Fiber module optical contamination of the signal transmission must be affected, the decline in the quality of transmission. Transmission quality, result in reduced receive sensitivity can also cause data loss phenomenon. Coupled with the use of used fiber transceiver, will be discounted on the life of component failure, etc. at any time.
