The AFRM4R-12s provides protection and management for fiber optic splices. The enclosure is equipped with 4 ports for cable entry. The enclosure accommodates (12) standard splice trays or (6) ½” deep splice trays. The AFRM4R-12 is available fully loaded with splice trays. The enclosure is configured for 19” racks but reversible mounting brackets allow quick conversion for 23” racks. Splice only enclosures may be combined with patch only enclosures to increase port density and improve access to splice trays in patch and splice scenarios.
