Specifications of the Fiber Optic Splice Box

Fiber optic splice boxes come in a variety of models with capacities from 12 to 256 splices, designed for indoor or outdoor deployment, supporting single fiber or ribbon splicing, and often include splitter and adapter integration.

Common Models and Capacities

The Fiber Cable Splice Boxes: Offer wall- or pole-mount enclosures with splice capacities of 12, 18, 24, or 36 splices, with options for customization. Outdoor models are IP-rated, UV-resistant, and corrosion-resistant, suitable for FTTH/FTTB and campus networks. They include hinged covers, labeled splice slots, bend-radius guides, and cable strain-relief for easy installation and maintenance.

Corning 2178 Splice Closure Family: Includes seven models—XSB, XLB, S, SL, LS, LL, and XL—available in flame-retardant and non-flame-retardant versions. These closures support ribbon and single fiber splicing, feature reusable gaskets for easy re-entry, and offer flexible tray systems for positional or fixed splice inserts. They are optimized for ribbon cables but compatible with all cable types.

Amphenol FS

B Series: Indoor wall-mount enclosures designed for centralized splice-only applications. They support ribbon or single fiber splicing, with removable splice trays, integrated baskets for loose tube storage, and multiple cable port sealing options (rubber grommets, compression seals, or conduit fittings). These enclosures are suitable for DAS, MTU, and MDU networks.

Phoenix Contact FD

X 20 Series: Compact DIN rail-mounted splice boxes for high-speed data transmission. They provide up to 12 duplex front connections, ensuring secure fiber connections in a compact, uniform design suitable for real-time data applications.

BW

N Fiber Splitter Boxes: Designed for FTTH deployments, these enclosures range from 16-port indoor wall-mount to 256-port underground handholes. They house splitters, splice trays, and adapter panels, managing cable strain relief, bend radius, and environmental sealing. They are used as optical distribution points where a single feeder fiber splits into multiple subscriber fibers.
