EB-LINK extends the free coding service of optical modules to the DAC and AOC product lines. The EEPROM at the cable head can be preset with compatibility information according to the switch brand, and can be written and rechecked before shipment.

Why do cables also need to be coded?

When a non-certified cable is inserted, some switches will report an unknown module on the management interface, limit the port rate, and even require manual release. The manufacturer and model fields in the head-end storage are the basis for its judgment. Although copper cables and AOCs do not have lasers, they also have these fields, so compatibility issues do not only occur with optical modules.

Information required when placing an order and returning to the factory

  • Device brand and specific model, including software version of the port board.
  • Different versions of the same brand have different strictness of identification fields, so the version information must be written clearly together.
  • Port requirements: 10 Gigabit port10G AOC active optical cable, 25G oral25G DAC high speed cable, the two-port type is marked to avoid mismatching.
  • The existing cables on the shelves can be registered in batches and returned to the factory for preset, without the need to process them one by one on site.

After writing, it needs to be rechecked.

Cables with preset compatibility information will go through link and identification checks again to confirm that the field reading is normal before packaging. For those who are renovating old networks, what is saved is the operation of manually releasing ports one by one after being put on the shelf, and there is a basis for replacing the same batch of equipment between switches of different brands. The re-inspection record is bound to the batch number. This parameter can be directly used when the switch of the same model is expanded later.

This service covers the general specifications of the computer room stacking line series. Whether the specific brand and version can be preset is subject to confirmation. You can call 0755-83179002 during working hours or send an email to sale01@eb-link.com.cn.
