As is well known, fiber optic transceivers are Ethernet transmission devices that exchange electrical signals from twisted pair cables and optical signals from optical fibers, hence also known as optoelectronic converters. The use of fiber optic transceivers can extend the transmission distance of the network to over 100 kilometers. I believe everyone may encounter some problems during the use of fiber optic transceivers. Recently, some users have inquired about the issue of fiber optic transceivers crashing. Below, we will share with you how to solve the problem of fiber optic transceiver crashing.
1. Many network disconnections are caused by switches, which perform CRC error detection and length verification on all received data. Packets with errors detected will be discarded, and correct packets will be forwarded. However, some erroneous packets during this process cannot be detected in CRC error detection and length verification. These packets will not be sent or discarded during the forwarding process, and will accumulate in the dynamic cache (buffer), never being able to be sent. When the buffer is full, it will cause the switch to crash. Because restarting the transceiver or switch can restore communication to normal at this time, users usually think it's a problem with the transceiver.
2. In addition, the internal chips of fiber optic transceivers may also crash under special circumstances, which is generally related to the design. If the chip crashes, simply power up the device again.
3. Fiber optic transceiver heat dissipation issue. Generally, fiber optic transceivers are used for a long time; Aging. The heat generation of the entire equipment will continue to increase. If the temperature reaches a certain level, it will crash. Solution; Replace the fiber optic transceiver. Or add some heat dissipation measures to the usage environment. The cooling measures are similar to computer cooling, so we won't explain them one by one here.
4. The power supply issue of fiber optic transceivers. Some low-quality power supplies may age and become unstable after prolonged use. This judgment can be made by touching the power supply with your hand; See if it's very hot. If it is necessary to replace the power supply immediately, the cost of the power supply is low; No repair value.
The above is an introduction to the causes and solutions of fiber optic transceiver crashes, hoping to be helpful to everyone. In fact, the best way to avoid problems with fiber optic transceivers is to choose fiber optic transceivers with guaranteed quality when purchasing.
