The FAB-OFC-BDM-B4 is a compact dome-type fiber optic splice closure, ideal for small to medium FTTx deployments where space efficiency and easy maintenance are priorities. Its mechanical sealing structure provides a reliable and reusable solution for environments requiring frequent access or changes without the need for specialized tools.
This model supports up to 48 fibers in bunchy configuration and 72 fibers in ribbon format, distributed across four internal splice trays. Each tray accommodates single and dual-layer fusion, as well as ribbon fusion, offering versatile cable management in a minimal footprint.
Designed with four 16mm ports and built from high-strength polycarbonate (PC), the closure is resistant to environmental stress and impact. Thermoplastic rubber sealing provides additional protection against dust, water, and temperature fluctuations from -40°C to +65°C.
Perfect for aerial, direct buried, wall-mounted, pipelined, or manhole installations, the FAB-OFC-BDM-B4 ensures robust performance in compact fiber access points or last-mile connections.
