The 288-type optical distribution box typically measures 816 × 616 × 323 mm (H × W × D) and weighs 35 kg.

The 288-type optical distribution box, such as the FDH 288 SIS model, is designed for PON optical networks and can accommodate up to 288 subscribers using 24 modules with 12 SC adapters each. It features a hinged frame for easy module installation, integrated holders for up to 11 PLC splitters, and patchcord management with parking for unused connectors. The cabinet is made of glass-reinforced polyester (SMC), is UV-resistant, and has an IP66 ingress protection rating with IK10 impact protection for outdoor durability (816 × 616 × 323 mm, 35 kg) .

Key Features

• Capacity: Up to 288 SC/LC ports, supporting 11 PLC splitters (1:32)
• Splice Capacity: Maximum of 624 splices
• Patchcord Management: Supports patchcords up to 2 mm diameter and 1.5 m length
• Mounting Options: Wall, pole, pillar, or direct trench installation without a concrete base
• Environmental Protection: IP66, IK10, UV-resistant, flammability V0
• Material and Color: Glass-reinforced polyester, light gray (RAL 7035) Other 288-type cabinets, such as the OHC3-288, are constructed from powder-coated aluminum and provide similar capacity for 288 distribution adapters, with dual access doors and grounding provisions for secure outdoor deployment . These cabinets are suitable for high-density subscriber areas, multi-dwelling units, and both centralized and distributed optical network terminals. In summary, the standard 288-type optical distribution box is compact yet robust, with dimensions of 816 × 616 × 323 mm, designed for high-density fiber distribution and outdoor environmental resilience .
