Article Overview
Telecommunications distribution boxes vary by type, capacity, and mounting, with dimensions, internal clearances, and protection ratings specified for indoor and outdoor applications.
Overview of Distribution Box Types
Telecommunications distribution boxes are designed for indoor or outdoor use and can accommodate various connection modules, back-mount frames, and protective components. They are typically made from metal (GI sheet) or durable plastic, with provisions for earthing, cable entry, and secure locking. Boxes comply with standards such as TIA/EIA568A/B, CE, RoHS, ISO, and may have IP-55 protection for outdoor models .
Key Specifications Table
| Box Type | Material | Capacity / Pairs | Internal Clearance | Mounting | Protection | Features |
|---|---|---|---|---|---|---|
| TOP-TS / TOP-TF / TOP-LS / TOP-PS / TOP-PF / TOP-S | Metal (GI sheet) | 1-way to 36-ways | Varies by model | Wall or pole mount | IP-55 | Reinforced body, slanted roof, Godrej 3-position lock, solid earthing points |
| 100 Pair Telephone Distribution Box | Plastic | 100 pairs | 70mm (low-profile), 90mm (standard) | Wall mount, multiple configurations | N/A | Removable side/end panels, cable tie anchors, jumper rings, connector mountings, secure cover with recessed screws |
| Indoor/Outdoor Telephone Distribution Box | Metal | 8/10 pair, 25 pair, 10 pair STG, MDF, STB modules | Standard DIN rail mounting | Wall, wood, metal, concrete pole | N/A | Quick-connect modules, back-mount frames, rubber grommets, lid snaps open, lockable cover, easy access for terminations |
Additional Details
- Outdoor Metal Boxes: Fabricated from 2 mm GI sheet with reinforced channels, slightly slanted roof with 50 mm overhang, and concealed hinges. Locking is typically a Godrej 3-position system, with additional manual locking options. Earthing points are provided on both sides .
- Plastic Boxes: Designed for modularity, allowing multiple boxes to be joined using base clamps. Covers vary in profile to accommodate different back-mount frames and protective components .
- Mounting and Installation: Boxes can be mounted on walls, poles, or concrete structures. Standard DIN rails are used for module mounting, and rubber grommets protect cables at entry/exit points .
- Compliance and Standards: Boxes are designed to meet TIA/EIA568A/B, CE, RoHS, and ISO certifications. Outdoor boxes are tested for IP-55 protection to ensure resistance to dust and water ingress . This table and specifications provide a comprehensive reference for selecting the appropriate telecommunications distribution box based on capacity, material, mounting, and environmental protection requirements.
