Recessed Steel Enclosure for Optical Fiber Signal Distribution within Residential Units Specifically designed for fiber optic cabling in buildings in compliance with CEI 306-22 guidelines, its compact dimensions allow for versatile use beyond standard applications. It is particularly suitable for structured cabling installations in scenarios where a traditional 19” rack enclosure would be too bulky or aesthetically incompatible with the needs of a single residential unit that lacks a dedicated technical room for system management.
