Maintain optical connectors

Optical connectors use optical fibers as the transmission medium. Optical connectors need more care than electrical connectors. Its maintenance is also more concerned about users, today we will talk about how to maintain the light connector.

Maintain optical connectors

1 Cabling precautions

When wiring, the optical connector should be protected and the cable should be straightened out, and then laid out; Do not twist, bend or trample the cable at a small Angle. The pulling force should be kept within the allowable range.

Static bending radius R≥10D; Dynamic bending radius R≥20D. (D is cable diameter)

When the cable is more than long, it should be wound and bundled, and it is forbidden to fold and bundle directly.

Optical cable binding should be moderate tightness, excessive binding of optical cable will squeeze the optical fiber, thus affecting the transmission performance of the optical cable.

2 Precautions for use and maintenance

The need for proper maintenance of optical cable lines, including:

Cable line inspection: visual inspection connector is loose, cable is fixed firmly, appearance is damaged or potential risk factors.

Cable line loss test: to determine whether the cable line loss meets the requirements of optical communication system, it is necessary to use OTDR or portable light source, optical power meter and other tests from time to time.

Optical cable line maintenance: the maintenance of optical cable line is divided into on-site maintenance and maintenance.

On-site maintenance includes:

Connecting structure locking: when the locking of the connector is loose, tighten the shell to make the connector lock again.

Contact cleaning: If the connection loss is too high, use a proper cleaning tool to clean the contact end face to remove dust and grease and restore the connector performance.

Replacement of optical cable components: when the damage cannot be repaired, it is necessary to replace the new optical cable components.

Return to factory for maintenance:

When the maintenance conditions are not available on site, remove the optical cable assembly and return it to the factory for maintenance.
