As a local area network connector device, the single-mode optical fiber transceiver's main task is how to seamlessly connect the two parties' data. Therefore, it is necessary to consider its compatibility with the surrounding environment, as well as the stability and reliability of its own products. On the contrary, no matter how low the price is, it cannot be used!
Single Mode Fiber Optic Transceivers
1. Whether it supports full duplex and half duplex
Some chips on the market can only use the full-duplex environment at present, and cannot support half-duplex. Serious collisions and packet loss.
2. Has the connection test been done with other fiber optic transceivers?
At present, there are more and more fiber optic transceivers on the market. If the compatibility of different brands of transceivers has not been tested beforehand, there will also be packet loss, long transmission time, and sometimes fast and slow.
3. Is there a safety device to prevent packet loss?
When manufacturing single-mode fiber optic transceivers, some manufacturers use the register data transmission mode to reduce costs. The biggest disadvantage of this method is instability and packet loss during transmission, and the best is to use buffer circuit design. Data packet loss can be safely avoided.
4. temperature adaptability
When the optical fiber transceiver itself is used, it will generate high heat. When the temperature is too high (generally not higher than 85°C), does the optical fiber transceiver work normally? What is the maximum allowable operating temperature? For a device that needs to run for a long time, this is very important. It deserves our attention!
5. Whether there is IEEE802.3u standard
If the fiber optic transceiver conforms to the IEEE802.3 standard, that is, the delay time is controlled at 46bit. If it exceeds 46bit, it means that the distance transmitted by the fiber optic transceiver will be shortened! ! !
The above is the purchase principle of single-mode fiber optic transceiver, I hope it can help you. Friends in need are welcome to consult.
