D.6.3 Crystal Fiber Cords for Long Wavelength
* Temporary tension applied when the cable is laid. The maxim allowable tension that can be
applied to the neck of the optical connector is 2 kg. The applicable optical connector is FC type
(complying with JIS C 5970 F01).
Note: 1. For cable specifications other than those shown above, contact your Yaskawa representa-
tive.
2. If cables manufactured by another company are to be used, present the above optical fiber
core specifications to that company.
