Screened Cat 5e cables stand up to sun, extreme temperatures

Feb. 11, 2011
Superior Essex's newest cable can withstand 720 hours of harsh UV and heat.

Superior Essex's newest Category 5e F/UTP cables - the CMR/CMX Outdoor and the CMR/CMX Outdoor Sunlight Resistant - are both resistant to failure when exposed to extreme temperature and prolonged ultraviolet (UV) rays.

Both cables are designed for outdoor applications that require shielding and a ground wire for Power over Ethernet (PoE) devices, Superior Essex says. The jacket of each is designed to resist temperatures between -20 deg. Celsius and +65 deg. Celsius. Additionally, the CMR listing of each allows the cable to be used in riser spaces per UL 1666, eliminating the need to transition to more fire-resistant cables upon entering a building.

The black Cat 5e CMR/CMX Outdoor Sunlight Resistant cable has been tested to resist 72 hours of harsh UV and heat, and is listed as UL 444 Sunlight Resistant-compliant. The level of UV protectings prevents damage from long-term UV sunlight exposure, Superior Essex says. The Cat 5e CMR/CMX Outdoor cable, suitable for more moderate UV exposure, has been UV/heat tested for 300 hours, the company says.
