(b) When connecting an optical fiber cable to Q80BD-J71LP21-25, Q81BD-
J71LP21-25, Q80BD-J71LP21S-25, Q80BD-J71LP21G and Q80BD-
J71LP21GE the restrictions on the bending radius should be observed.
For bending radius details, check with the cable to use.
(c) Maintain the bending radius of the optical fiber cable within the allowable
range using a tool for securing the optical fiber cable bending radius.
This tool may be purchased from Mitsubishi Electric System Service, Inc, or
your nearest dealer. Please inquire for more information.
(d) When laying the optical-fiber cables, do not touch the fiber cores of the
cable and module connectors, and do not let dust or particles collect on
them.
If oil from hands, dust or particles adhere to the cores, the accumulated
transmission loss may cause malfunctions in the data link.
Do not detach the cover until the cable is attached.
(e) When attaching or detaching the optical fiber cable to/from the module, pull
or insert the cable by holding the cable connector securely with your hand.
(f) Connect the cable and module connectors securely until you hear a "click"
sound.
(g) When attaching or detaching the optical fiber cable to/from the module,
make sure to power off the personal computer and external power supply.
