Superior Essex Communications Announces Expansion of Fiber Optic Cable Manufacturing Facility to Meet Continuing Broadband Demand Nationwide
The $73 million investment will create manufacturing jobs and help connect ...
Copper Premises and Outside Plant (OSP) cables from Superior Essex have a 300 volt working voltage capability when used in communication circuit applications.
Communications cables, commonly referred to as low voltage cables, are not required to be marked with a voltage rating or listed as such by any listing or testing organization.
Although not marked, our copper premises products have a 300-volt rating meeting the requirements of UL Standard 444, which states that wires listed as CMR or CMP are qualified for a 300-volt rating.
In OSP cables, the voltage capability is purposefully omitted from the cable jacket, replaced with a telephone handset to avoid confusion in the field with high voltage power cables.
The working capability of traditional 300-volt applies to OSP copper telecommunications cables manufactured in compliance to specifications including PE-39, PE-89, PE-86, Telcordia GR-421-CORE and GR-492-CORE as well as newer EnduraGain™ OSP Category 5, 5e, 6 and 6A designs.
