Fiber Optic Splice Closures (FOSC)
Our horizontal (or inline) fiber optic splice closures are durable housings designed to organize, protect, and secure fiber optic splices in long-distance or backbone installations. With an elongated, cylindrical or flat design, they support inline fiber routes where cables enter and exit from opposite ends, and many models feature mid-span access—enabling specific fibers to be tapped without cutting the entire cable. Made from high-tensile plastic with dependable sealing, these closures provide robust protection against water, dust, and harsh conditions. Suitable for wall, duct, aerial, or underground mounting, they offer flexible deployment in both outdoor and indoor environments while ensuring long-term mechanical integrity and reliable fiber management.
HTB-133
The HTB-133 horizontal splice closure features 8 cable ports, 16 drop cable ports, and supports up to 24 splices using a single splice tray. It accommodates cable diameters up to 16mm across 4 ports, 8 mm across 4 ports, and 3mm drop cable across 16 ports while also supporting smaller cables as needed. A mechanical sealing system ensures strong protection against water and dust ingress—with an IP rating of IP68. Internal components are made from durable ABS plastic, and stainless-steel hardware provides added strength and long-term reliability in the field.
