The questions called from the scene had similar syntax, but the causes were scattered in three stages: model selection, matching and construction. EB-LINK writes down the most frequently asked questions in consultations as quick questions and quick answers. Each question only gives you what to check first and does not start the growth process.

What should I check first if it is not recognized when plugged in or the link cannot come up?

First check whether the speed file matches the port, and then check whether the A and B marks on both ends of the single fiber are paired. Most of the cases where there is no response when plugged in are due to these two items. If the same speed and wavelength are still not recognized, check whether the port declares that it supports this gear.SFP 2.5G multi-mode dual fiber optical moduleIf installed on a port that does not support 2.5G, the link will not work.

Can connect but packet loss and intermittent disconnection, what should I check first?

Read the receiving and receiving light first, and then see if the distance range is too low. The light collection is close to the sensitivity, and the distance setting is just below the line. This is a common combination that can connect but occasionally causes packet loss. The second step is to check the end face cleaning and jumper bending, focusing on the weak current well and the outdoor lower section.100M single mode single fiber one optical one electrical fiber optic transceiverWhen this type of end is bent, there is often a pattern of normal symptoms in the morning and deterioration in the afternoon.

What should I check first if the readings are wrong or the screen freezes?

• There is a large discrepancy between DDM and network management readings: first confirm whether the module writing caliber is consistent with the equipment brand;
• The light intensity of the short link is too high: first check whether it should be pressed a little instead of repeatedly wiping the connector;
• The screen freezes but there is no packet loss: Check the bandwidth level first. Running multi-channel high-definition files at 100M is bound to be limited;
• If the port alarm occurs after replacing the module: first check whether the encapsulation and rate are consistent with the original port.

What several answers have in common is to check the gear position first, then check the construction, and finally talk about the configuration. After this round of judgment is completed, most phenomena can be identified within ten minutes of powering on. For the remaining situations that require careful judgment, the phenomena and readings can be explained clearly at once. You can call 0755-83179002 for technical support.
