Cautions for installation the SSCNET III cable

SSCNET III cable is made from optical fiber.
If a force is applied to the optical fiber such as a major shock, lateral pressure, haul, sudden bending or twist,
its inside distorts or breaks, and optical transmission will not be available.
Carefully read the precautions in this manual when handling the SSCNET III cable.
For detailed specifications of the SSCNET III cable or details on the assembling procedure, refer to the
following manual.
1) Minimum bend radius
Make sure to lay SSCNET III cable with bending radius greater than the minimum bend radius.
If the SSCNET III cable is less than the minimum bend radius, optical transmission is interrupted and it
may cause malfunctions.

2) Tension
If tension is applied to the SSCNET III cable, increase of transmission loss occurs due to external forces
which concentrate on the fixing part of SSCNET III cable or the connecting part of SSCNET connector. In
the worst case, the SSCNET III cable may break or be damaged. When laying SSCNET III cable, handle
without applying forced tension.
3) Lateral pressure
If lateral pressure is applied to the optical cable, the SSCNET III cable itself distorts, the internal optical
fiber gets stressed, and transmission loss will increase. In the worst case, the SSCNET III cable may
break. To avoid lateral pressure while laying cable, do not bind the SSCNET III cable with things nylon
bands (TY-RAP).
4) Twisting
If the SSCNET III cable is twisted, it is the same as when local lateral pressure or bending stress is
applied. Consequently, transmission loss increases, and in the worst case, the SSCNET III cable may
break.
