between the fiber cord and optical connector when installing the
cable, you can hold the reinforcing cover of the connector directly
and pull it. In the case of an internal cord, which does not have a
reinforcing cover, apply the same protective measures, as
instructed in Fig. D (d), for that portion of the cable where the two
cords are bound together, in order to prevent a tensile force from
being applied between the fiber cord and optical connector. In the
same way as for an external cable, if no tensile force is applied
between the fiber cord and optical connector during installation,
you can hold the shielded part of the cable directly and 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 (e), to prevent the weight of the 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.
