Fiber Optic Closure BOFC-C2

AJW BOFC-C2 is designed to manage fiber splices with ease of maintenance for installers. Its versatility and durability allow direct buried, underground and aerial applications with flame retardant and UV resistant body. It is a mechanical closure, sealed with a silicone rubber gasket designed and shaped according to the groove of the closure. The sealing gasket can be easily replaced when damaged. The sealing gasket remains water-proof even with opening and closing the closure multiple times. It is easy and convenient to install and helps to reduce installation time and training. It offers mid-span application.

It is compliant with Telcordia GR-771-CORE, IEC 61300-2-22, IEC 60068-2-14, and satisfies Test Methods; IEC 61300-2-38 Method B: IEC 61300-2-38 Method A; IEC 60068-2-17 Test Qc: IEC 61300-3- 1; IEC 61300-2-12 Method B; IEC 61300-2-23 Method 2; IEC 61300-2-34; IEC 61300-2-26; IEC 60068-2-11 Test Ka; IEC 61300-2-22; IEC 60068-2-14 Test Nb; IEC 61300-2-33.
Horizontal sealed box design, assembled from two shell pieces and connected by bolts and screws.
Service Life: more than 20 years, Warranty: 2 years
Reusability: Minimum 10 opening and closing cycles while maintaining technical specifications: tight sealing; no deformation, cracking, or breakage of the switchgear components.
Made of black synthetic resin, resistant to UV rays and rodents; does not age, become brittle, crack, or break over time.
Resistant to chemical corrosion and capable of withstanding a minimum compressive force of 1000N/25cm², and impact from a 1kg steel ball dropped from a height of 2m (for underground connectors) and 1m (for overhead connectors).
Features identifying marks (serial number or engraved year/month of manufacture or warranty sticker that does not peel or flake in water) ensuring easy identification for warranty purposes.
Waterproofing Mechanism:
- The sealing gasket must be seamless, fitted precisely between the two sleeve pieces, and made of elastic silicone rubber material, allowing for multiple opening/closing cycles without replacement, ensuring watertightness (do not use gaskets made of soft rubber).
- At cable entry/exit ports: use sealing plugs made of elastic silicone rubber, allowing for multiple uses, and ensuring watertightness (use soft rubber only in the case of subscriber line connections).
- If using waterproofing gel to enhance watertightness: use a grease-like gel, insoluble in water, easy to wipe clean, and easy to clean when opening/closing the sleeve (do not use hardened silicone sealant).
Fiber optic cable fixing mechanism in a sleeve:
- Securely fix the cable collar using a plastic cover of appropriate size for the cable diameter + bolts, screws, or stainless steel clamps.
- The central reinforcing component of the cable, after fixing, must be parallel to the horizontal plane and not bent or broken. The bolts securing the reinforcing wire must not be stripped, broken, or have damaged threads.
Vibration damping mechanism:
- The splice enclosure meets the vibration damping standard at frequencies of 5Hz => 55Hz => 5Hz, sinusoidal waveform with a minimum amplitude of 1 mm.
- The splice trays are securely installed inside the splice enclosure.
- Requirement: The splice enclosure must be airtight, free from cracks or breakage, and must not affect the quality of the optical fiber (splicing loss should not exceed 0.05 dB) after testing.
Cable tray capacity (number of splices supported) and number of cable entry/exit ports:
- 144Fo cable tray capacity: 6 cable entry/exit ports, and supports 144 splices.
- All cable ports, before cable connection, must be sealed or have stoppers to ensure airtightness and prevent dust and water ingress.
