144 Optical Cross-Connect Box Base Dimensions

A typical 144-core optical cross-connect cabinet measures approximately 590 mm × 420 mm × 300 mm (L × W × H) for the chassis, with a foundation hole line of 405 mm × 170 mm × 300 mm.

Cabinet Body and Material

The cabinet is usually made of high-strength polyester SMC or cold-rolled steel, offering corrosion resistance, aging resistance, and the ability to withstand harsh outdoor environments. It is designed to be moisture-proof, dustproof, waterproof, and salt-spray resistant, with a protection level of IP65 .

Mounting Options

These cabinets can be wall-mounted, pole-mounted, or ground-mounted, providing flexibility for different network deployment scenarios . The cement pedestal or foundation allows secure installation above water level, and expansion bolts can be used for additional stability .

Internal Configuration

• Splice & distribution trays: Typically, 12-core trays are used, with 2 sets of 12 trays for a total of 144 cores. Trays allow direct splicing and storage of optical fibers, with separate sections for splicing and storage .
• Adapter installation: FC or SC adapters are card-mounted at a 30° angle to the front of the cabinet, ensuring a minimum bend radius of ≥40 mm to prevent fiber damage .
• Splitter ports: LGX-type PLC splitters (1:8 or 1:16) can be installed in the cabinet for fiber distribution .

Additional Features

• Load capacity: The cabinet cover can withstand ≥980 N, side surfaces ≥500 N, and hinges ≥200 N .
• Electrical protection: Tank pressure protection between the ground and chassis is ≥3000 V (DC)/1 min without breakdown .
• Service life: Designed for up to 20 years in outdoor conditions . These dimensions and features make the 144-core optical cross-connect cabinet suitable for FTTH networks, telecom, CATV, and data communication networks, providing high-density fiber management and reliable protection for optical fibers .
