The Main Cause and Solution of Optical Transceiver Failure

Customers will more or less encounter various failures when using optical transceivers, among which the more common failures are link failure and packet loss. This article will focus on explaining the causes and solutions of optical transceiver failures.

Link Failure

As a responsible and reliable optical module supplier, we remind you that the following causes may lead to failure:

  • Optical link failure caused by optical port pollution and damage: If the optical transceiver is not in use, the dust cap must be covered to avoid link failure caused by dust pollution to the optical port.

  • Pollution or failure of the end face of the optical fiber connector: During the installation, commissioning and maintenance of the network, the optical fiber connector often undergoes multiple plugging and unplugging processes. In this process, often due to the operator not paying attention to the protection of the connector end face, the end face of the optical fiber is polluted, which affects the decline in the transmission performance of the optical link, and in severe cases will lead to the paralysis of the entire optical fiber link.

  • ESD damage: Static electricity will absorb dust, change the impedance between lines, and affect the function and life of the optical transceiver.

  • Use low-quality transceivers: low-quality optical transceivers will have problems such as failure, packet loss, unstable transmission, and large optical attenuation.

  • The wavelength and mode of the optical transceiver at the opposite end do not match: the wavelength of the optical transceiver needs to be matched at each end, and the wavelength mismatch may cause data loss during transmission. In addition, the working mode of the optical transceiver should also be matched at both ends, and the full-duplex optical transceiver should be paired with the full-duplex optical transceiver.

  • The transmitting and receiving optical power is too high or too low: check whether the optical power of the optical transceiver of the peer device is normal, and the transmitted optical power value must not be less than the minimum optical power value.

  • Optical fiber mismatch: In the absence of redundant single-mode optical fibers, multi-mode optical fibers can be used with single-mode optical transceivers, but it is best for single-mode transceivers to correspond to single-mode optical fibers and multi-mode transceivers to multi-mode optical fibers.

  • The conductive metal of the golden finger of the optical fiber transceiver is missing: the missing of the golden finger will cause the optical fiber transceiver to fail to work normally. The conductive metal of the golden finger of the unqualified optical fiber transceiver is missing, and the luster is obviously not enough.

Packet Loss

  • The optical transceiver does not match the electronic function circuit of the device;

  • The main chip does not match the device;

  • Physical line failure;

  • Equipment failure;

  • Wrong routing information;

And we are capable to provide wholesale compatible optical transceiver.

To sum up, in order to greatly reduce the probability of failure of the optical transceiver in use, it is best to choose an optical transceiver with reliable and stable performance and guaranteed quality. lines and other related equipment.
