Optical Fiber Cables

Wire the RJ71GN11-SX with optical fiber cables.

Wiring methods

The following describes connection and disconnection of the optical fiber cable.
Connecting the cable
1.
Push the optical cable connector into P1 or P2 until it clicks, paying attention to its orientation.
2.
Lightly pull it to check that it is securely connected.
Both P1 and P2 can be used.
Disconnecting the cable
1.
Press the connector hook down and unplug the optical fiber cable.
Precautions
• Place the optical fiber cable in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the cables or malfunction due to poor contact.
• Do not touch the optical fiber core of the optical fiber cable side connector, and protect it from dirt or dust. If oil from your
hand, dirt or dust is attached to the core, it can increase transmission loss, arising a problem in data link.
• Check that the optical fiber cable is not disconnected and there is no problem with the connector connection.
• Place the attached cover on the unused optical fiber port to prevent foreign matter such as dirt or dust.
• The bend radius of the optical fiber cable is limited. For details, check the specifications of the cable to be used.
• The laser class (JIS C 6802, IEC 60825-1) is class 1. Do not look directly at a laser beam. Doing so may harm your eyes.
