As soon as the vision station loses a packet, many people immediately want to change the camera or switch. In fact, there are only a few sources of link errors. Eliminating them in order saves time than blind replacement. It can also avoid replacing equipment that is not problematic, wasting budget and delaying the downtime window.

First check whether the error code will follow the device action.

Align the retransmission count with the time axis. If the bit error peak happens to fall at the moment when high-power equipment starts and stops, it is probably common mode interference; if it occurs at a constant low speed, it is more like poor line contact or oxidation of the crystal head. Record the optical power of the receiving end at the same time. Optical port bit errors are strongly related to optical power, while electrical port bit errors are strongly related to shielding and grounding. This step can determine the general direction first.

Isolate a section of line for verification

• Take the suspicious network cable out of the dense wire trough and walk it for a while. If the bit error decreases significantly, it proves the interference coupling.
• Replace it with a known good short wire to eliminate crimping and connector issues.
• Compare the performance of adjacent unmodified segments to confirm whether the bit error is contributed by this segment or common to the entire network.

Finally, determine the boundary of copper modification and keep a comparison

In scenarios such as cabinet backbones, wire troughs and power cables run in parallel and the distance exceeds 100 meters, copper cables are difficult to shield no matter how they are shielded. Optical fiber is directly avoided from the physical layer. There is no need to install all the short jumpers of more than ten meters at the end of the workstation with optical fiber, which will increase joint failure points. useGigabit single mode dual fiber one optical one electrical fiber optic transceiver or PCI-EX8 10 Gigabit single electrical port network card (Intel 82599 chip)For the optical port version, just replace the main trunk. Take the port count of one shift before and after the transformation for comparison. EB-LINK supports sending the on-site phenomena to determine whether optical fiber should be connected.
