Maintaining Cables that Connect to MX240 DPCs, MPCs, MICs, or PICs

Purpose
For optimum router performance, verify the condition of the cables that connect to the DPCs, MPCs,

from the connector.
Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage
the cable and cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments can cause
