pull it. Because the combined tensile strength of the two cords is
only 14 kg, however, avoid applying too great a force to the cable
during installation, regardless of whether you have taken the
protective measures.

D Take care to keep both parts of the optical connector (cable side and
PCB side) clean. If they become dirty, wipe them with tissue paper or
absorbent cotton to remove dirt. The tissue paper or absorbent cotton
may be moistened with ethyl alcohol. Do not use any organic solvent
other than ethyl alcohol.
D Fix the reinforcing cover of the external cable or the cord binding
portion of the internal cord type cable by using a cable clamp, as shown
in Fig. D.5, to prevent the weight of the optical fiber cable from being
applied directly to the connecting part of the optical connector.
(Recommended cable clamp):
Recommended cable clamps are listed below. Use a clamp that
grasps the optical cable lightly; the clamp should not apply
excessive pressure to the cable.
For an external cable:

For an internal cord type cable:
