D. OPTICAL FIBER CABLE

D Before installing an external cable, fix either a wire with a hook
or a tension member to the reinforcing cover of the optical
connector and pull the wire or tension member, as shown in Fig.
D(d). This is done to prevent a tensile force from being applied
between the fiber cord and connector. If no tensile force is
applied between the fiber cord and 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 connector.
In the same way as for an external cable, if no tensile force is
applied between the fiber cord and 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.
