When we buy fiber optic transceivers, price and performance are important factors, especially for some small and medium-sized enterprises. We generally believe that a few hundred yuan of products is enough to meet the needs of general enterprises, unless it is some special industries, such as telecommunications, military and so on. Of course, in addition to the price, the compatibility of the product with the surrounding environment and the stability and reliability of the product itself must also be considered. In order to help you choose a good fiber optic transceiver product, let me list some purchasing points for you.
1. Whether it supports full-duplex and half-duplex:
Check whether the fiber optic transceiver itself 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 Switch) Or a hub (HUB), which uses half-duplex mode, it will definitely cause serious collision and packet loss.
2. Whether the connection test has been done with other fiber optic transceivers:
See if it has been tested with other fiber optic connectors. There are more and more fiber optic transceivers on the market. If the compatibility of different brands of transceivers has not been tested beforehand, packet loss and transmission time will also occur. Too long, suddenly fast and slow, etc.
3. Whether there is a safety device to prevent packet loss:
See if it has a safety device to prevent packet loss, because many manufacturers often use the register data transmission mode in order to reduce costs when making fiber optic transceivers. The biggest disadvantage of this method is that data transmission will be unstable. , resulting in packet loss, and the best way is to use a buffer circuit design, which can safely avoid data packet loss.
4. Temperature adaptability:
Check whether the product has been tested for temperature, because the optical fiber transceiver itself will generate high heat when used, and the installation environment is usually outdoors, so when the temperature is too high (not greater than 50°C), whether the optical fiber transceiver can work normally Operation is a very important factor for users to consider! What is the maximum operating temperature allowed? For a device that needs to run for a long time, this is very worthy of our attention!
5. Whether it conforms to the IEEE802.3u standard:
See if the product conforms to the IEEE802.3 standard? If the optical fiber transceiver conforms to the IEEE802.3 standard, if it does not conform to the standard, there will definitely be compatibility problems.
6. After-sales service capabilities of manufacturers:
Measure the after-sales service of the manufacturer. Just imagine, if your optical fiber transceiver is broken and the manufacturer has not solved the problem for a few days, how much is your loss? Therefore, in order to enable the after-sales service to respond in a timely manner, it is recommended that you choose the local area It is a professional company with strong strength, superb technical force and good reputation. Only the technical engineers of professional companies have rich experience in troubleshooting, and the tools for detecting faults are more advanced!
7. Observe the appearance of the product:
When purchasing a fiber optic transceiver, carefully observe the appearance of the product to see if the fiber optic module casing of the product is old, shiny, or has signs of wear. In today's market, many manufacturers use second-hand or old fiber optic modules in optical fiber transceivers, fiber optic switches and other equipment in order to make huge profits. Products using these second-hand fiber optic modules will cause great hidden dangers to network transmission, such as: fiber optic The optical path of the module is polluted, which will definitely affect the signal transmission and reduce the transmission quality. The decrease in transmission quality reduces the sensitivity of reception, and also causes data packet loss. Coupled with the use of second-hand optical fiber modules, the service life will also be discounted, and parts will fail at any time.
Well, the above is the introduction of the main points of purchasing fiber optic transceivers. I hope it will be helpful to friends who purchase fiber optic transceivers. ZR optical fiber is mainly engaged in odf, pigtail, optical fiber cable, optical fiber cable, optical fiber jumper, single-mode optical fiber, optical fiber transceiver and other products, providing optical fiber solutions for integrated wiring enterprises in communication equipment rooms.
