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-119A
The HTB-119A horizontal splice closure features 6 cable ports and supports up to 144 splices across 6 splice trays. Increased capacity is available with the purchase of either TRAY-X2 or TRAY-X5 splice trays. Using the TRAY-X2 splice trays allow the splice closure to support up to 192 splices across 8 splice trays and using the TRAY-X5 supports up to 432 splices across 12 trays. It accommodates cable diameters up to 20mm (×2), 22mm (x2), and 25mm (×2), 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.
