SPFC-NV-12M-2/2M Fiber Optic Closure
Small Horizontal Splice Type · Up to 12 Cores · 2IN 2OUT
Product Overview
SPFC-NV-12M-2/2M is a compact horizontal fiber optic closure suitable for direct and branch connections (1-to-2 or 1-to-3) of various optical cables with diameter ≤φ10mm. It can be widely used in overhead, duct, direct burial and manhole environments, and is also suitable for all-plastic local telephone cable connections.
The product features a high-strength engineering plastic housing with reliable sealing, independent insulation grounding device, and all-metal components made of stainless steel for repeated opening in various environments.
Key Features
Meets National Standards
All performance indicators meet the requirements of the national YD/T814-2001 standard.
High-Strength Housing
Outer box body made of high-strength engineering plastics with characteristics of light weight, high mechanical strength, strong corrosion resistance, lightning resistance, anti-aging, and long service life.
Reliable Sealing
Box body and cable inlet sealed with silicone rubber, providing IP65 protection rating with reliable sealing performance.
Flexible Configuration
Configured plugs correspond to the entrance and exit, allowing users to make flexible choices according to the actual number of cables.
Independent Grounding
Independent insulation grounding device makes the grounding of the optical cable convenient and safe.
Stainless Steel Hardware
All metal components and fasteners outside the box body are made of stainless steel, which can be opened repeatedly in various environments.

Application Scenarios
- Overhead installation: Compact structure and lightweight design (only 0.99kg), side pressure resistance ≥2000N/10cm, suitable for overhead environment requirements.
- Duct installation: IP65 protection rating with silicone rubber sealing, moisture-proof and waterproof, suitable for underground duct environments.
- Direct burial: High-strength housing with corrosion and aging resistance, operating temperature range -20~+60℃, suitable for direct burial environment.
- Manhole installation: Stainless steel fasteners allow repeated opening and closing, excellent corrosion resistance, suitable for frequent maintenance in manholes.
- All-plastic cable access: Compatible with both optical cables and copper cables, meeting diverse application needs.
Installation Instructions
- Select a cable ring compatible with the cable diameter and penetrate it with the optical cable; strip the optical cable, remove the outer sheath, inner sheath, and loose tube, clean and remove the oil filling paste, leaving optical fiber length of 1.1~1.6m and 30~50mm steel core.
- Fix the cable block and the optical cable. If the diameter is less than 10mm, use self-adhesive tape to wind the fixed place to make the diameter reach 10mm before fixing.
- Introduce the optical fiber into the splicing tray, sleeve the heat shrinkable tube on any pair of fibers to be connected. After splicing, place the reinforced mandrel, ensuring the fusion splice is in the center of the protection tube. Heat appropriately to fuse the fiber and protection tube together, then clamp the connector into the fiber distribution slot (12 fibers per tray).
- Lay the remaining optical fibers evenly in the splice tray, arrange and position the coiled fibers with nylon cable ties.
- Locate and use the grounding wire according to requirements.
- Wrap the optical cable around the corresponding position of the cable inlet, pad sealing strips in the sealing grooves on both edges of the box shells, close the two shells and squeeze the stainless steel bolts symmetrically until fully tightened.
- Locate and fix the hanger for laying, installation complete.
