AFL Introduces Plenum-rated Indoor/Outdoor Loose Tube Cable

SPARTANBURG, SC — AFL is introducing the LQ-Series I/O Plenum Loose Tube Cable, developed to provide a lower cost inter-building cabling solution for campus-based networks. Because the LQ cable is tested and qualified to meet the leading industry cable standards for outside plant (OSP) and inside plant (ISP) plenum-rated fiber optic cables, it can be used as a single-cable solution for OSP and ISP cable installations. This dual-rating functionality eliminates the need to use separate cables for OSP and ISP route segments and the associated requirement to include a splice transition point within 50 feet of the inside plant to connect the two separate cables.

Combined Outside and Inside Plant Ratings
“The National Fire Protection Agency (NFPA) NEC guidelines allow for outside plant-only cables to be routed into a building space for up to only 50 feet,” explained Stephen Martin, RCDD, senior product manager for AFL’s Enterprise Cable division. “If the termination point of the outside plant cable is beyond 50 feet from the point of entrance into the building, the cable must be placed into a fire-protected pathway or spliced to a properly flame-rated inside plant cable.”

Martin continued, “AFL’s LQ-Series Indoor/Outdoor Plenum Loose Tube cable, with combined outside and inside plant ratings, eliminates the need to transition to a separate flame-rated inside plant cable when in-building termination points are beyond 50 feet from the entrance location.”

The cable construction consists of 12-fiber, gel-free buffer tubes stranded around a central strength member. The finished core is jacketed with a highly flame-retardant, UV-resistant thermoplastic. The LQ-Series cable is available with 12 up to 144 single-mode or multimode fibers. Applications include inter-building campus backbone connections, installation in OSP buried pathways or above-ground exposed cable trays, in cable routes that require cables to transit OSP space, and inside plant environments that require cables to be riser or plenum-rated.
