What is Horizontal Fiber Optic Splice Closure?
A Horizontal Fiber Optic Splice Closure (HFOSC), often referred to as an inline splice closure, is a robust, hermetically sealed protective unit engineered to safely contain, arrange, and safeguard both fusion and mechanical splices of optical fibers in outdoor and buried fiber-optic communication systems. As an essential passive component, it guarantees signal stability and long service life in backbone networks, distribution networks, and FTTH deployments.
Horizontal Fiber Optic Splice Closure Overview:
Key Features of Horizontal Fiber Optic Splice Closure:
· IP68 Waterproof & Dustproof: The highest ingress protection rating, fully submersible and impervious to water, dust, sand, and soil contaminants.
· Mechanical / Heat-shrink Sealing: Reliable, re-enterable sealing systems (no adhesives required) ensure airtight protection and allow for future network upgrades.
· Wide Temperature Resistance: Operates stably in extreme environments from -40°C to +65°C (or up to +85°C for premium models).
· High Fiber Capacity: Available in various sizes, typically accommodating 24, 48, 72, 96, 144, up to 288 fibers (both loose-tube and ribbon fibers).
· Modular Splice Trays: Internal stackable/semi-circular splice trays (12/24 fibers per tray) with fiber guides to ensure minimum bending radius (>30mm) and optimal fiber management.
· Flexible Port Configuration: Common designs include 2-in/2-out, 3-in/3-out, 4-in/4-out ports, compatible with cable diameters from Φ8mm to Φ25mm.
· Impact & UV Resistance: Robust exterior casing withstands physical impact (IK08 rating) and long-term solar UV radiation.
· Versatile Installation: Supports aerial (pole-mounted), direct burial, duct/manhole, and wall-mounted installations.
