Optical Closures for Underground
FSCO-FB/FB3 Series
The FSCO-FB/FB3 Series is a compact, high-density underground fiber optic in-line closure designed for small handholes. It offers an optional hanging bracket for aerial application. The closure utilizes non-adhesive low-hardness rubber for easy reassembly. It also has an optional leakage detection module for detecting inundation with the optical path monitoring system.

FSCO-FB/FB3 Series
The cable entry section is in-line, making it ideal for use in space-constrained manholes and handholes.
The closure utilizes a band mechanism, simplifying both assembly and disassembly while providing support for SWRTM/WTCTM and loose tube cables.
Moreover, the cable entry section can accommodate a maximum of six cables, including one set of main cables (two pieces) and four branching cables, ensuring efficient connectivity.
