When a fault occurs on-site, it is often too late to wait for engineers to arrive. Whether remote assistance can be used well directly determines the speed of link recovery. EB-LINK's technical support opens three entrances: telephone, email, and QQ, each with its own usage.

Choose the entrance according to the degree of urgency. Don't just focus on one.

If the link is interrupted and business is affected, please call 0755-83179002 or 0755-88844562 directly for real-time communication within working days; if you need to send photos, logs, test screenshots and ledgers, please send the email to sale01@eb-link.com.cn to save the data for easy review; if the discussion period is long and you provide feedback while testing, use QQ 1416090645 to hold the conversation and follow up step by step.

When asking questions, state four things clearly at once

Remote judgment is most afraid of squeezing out toothpaste-like information. When asking questions, organize them according to four aspects: project site environment and equipment brand model, fault phenomenon and occurrence time, link parameters (rate, distance, module model), operations that have been performed and results. For example, industrial site1-way 3G-SDI audio and video optical transceiverIf the picture is interrupted, it means whether it is a regular interruption or an occasional interruption, and whether there was any construction or power supply changes before the interruption.

In the remote demarcation stage, on-site cooperation is like this

Technical support usually provides two or three steps for verification: patching fiber jumpers to eliminate end-face problems, transposing modules and transceivers to locate bad pixels, and reading DDM transmitting and receiving optical power to compare with the acceptance baseline. When cooperating, the results of each step are returned, and the conclusion converges quickly; for strong electromagnetic environments such as electricity, please refer toCommunication transformation plan for electric power and new energy stationsThe isolation idea here determines interference factors.

If the problem cannot be solved remotely, go back to the repair channel and clearly write down the links that have been eliminated, which can save a round of repeated testing. The address is on the 4th floor, Building 3, Hehe Technology Park, Dashuikeng 2 Village, Guanlan Street, Longhua District, Shenzhen. Please call to confirm before mailing the faulty parts.
