GMLT-SS15 Multi Loose Tube

The PAMIX GMLT-SS15 Outdoor Optical Fiber Cable is a rugged, steel-armored cable engineered for demanding outdoor environments. Suitable for underground ducts, laying on cable trays, and direct buried applications, this multi-loose tube cable provides exceptional mechanical performance, temperature stability, and superior protection against rodents.

General Construction & Application This cable is built around a robust 1.9 mm steel central strength member. It features a multi-loose tube structure made of PBT, with each tube filled with a thixotropic jelly compound and surrounded by a flooding jelly compound for complete water blocking. A 0.2 mm corrugated steel tape armor layer ensures high rodent protection and excellent crush resistance. The entire core is protected by a UV-resistant, 1.5 mm black PE outer jacket equipped with rip cords for easy stripping. This design prevents loose tube shrinking and offers excellent hydrolysis resistance.
