(Note-1) : For wiring duct with 50[mm] (1.97 inch) or less height.
(Note-2) : 20mm (0.79inch) or more when the adjacent module is not removed and the extension cable is connected.
(d) Twisting
If the SSCNET cable is twisted, it will become the same stress added
condition as when local lateral pressure or bend is added. Consequently,
transmission loss increases, and the breakage of SSCNET cable may
occur at worst.
(e) Disposal
When incinerating optical cable (cord) used for SSCNET cable, hydrogen
fluoride gas or hydrogen chloride gas which is corrosive and harmful may
be generated. For disposal of SSCNET cable, request for specialized
industrial waste disposal services who has incineration facility for disposing
hydrogen fluoride gas or hydrogen chloride gas.
(f) Wiring process of SSCNET cable
Put the SSCNET cable in the duct or fix the cable at the closest part to the
QD74MH with bundle material in order to prevent SSCNET cable from
putting its own weight on SSCNET connector.
Leave the following space for wiring.
