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-TW01
The HTB-TW01 horizontal splice closure features a reliable heat shrink sealing system, providing a secure and airtight seal ideal for demanding outdoor fiber optic installations. Designed with 4 ports—2 on each side—the closure accommodates cables up to 20 mm in diameter, supporting versatile midspan and inline splicing configurations.
Its extended port design facilitates effective heat shrink sealing, ensuring enhanced protection against moisture, dust, and environmental contaminants. With a splice capacity of 96 fibers across 4 splice trays, the HTB-TW01 offers robust fiber management in a compact footprint measuring 356 mm x 232 mm x 60.5 mm.
Built for durability and ease of installation, this closure is well-suited for aerial, duct, and underground deployments where a dependable, heat shrink sealing solution is required.
