Closet connector housings (CCHs) provide interconnect or cross connect capabilities between outside plant, riser or distribution cables and opto-electronics. Like other LANscape® solutions hardware, the housings accept CCH connector panels. In addition, the housings accept CCH cassettes and CCH modules. From fiber and cable routing and strain relief, to port labeling and termination, these housings reduce the risk of error that can disrupt networks. The units are designed for rack mounting in 19 in racks or optional 23 in equipment racks (1.75 in EIA hole spacing). They are available in rack space options of 1U (two panels, cassettes or modules), 2U (four panels, cassettes or modules), 3U (six panels, cassettes or modules) and 4U (12 panels, cassettes or modules). The 1U, 2U and 3U options feature a slide-out tray and see-through, removable top covers. The CCH-04U features a clear door, removable front and rear enclosures and a platinum-colored interior for maximum visibility and access. All size housings have field installable lock kits available for both front and rear doors. All CCH housings can also be upgraded for pigtail splicing to full fiber capacity and easy, modular fiber management through the use of CCH splice cassettes (CCH-CS), or for easy, modular fiber management when using field installable connectors through the use of CCH slack cassettes (CCH-CF).
