X 8-position modular jack and plug. • Pin/pair assignments configured T568A or T568B. X 568SC and ST-style fiber connectors. X SFF fiber connectors: LC and MT-RJ. Horizontal Cabling Topology and Design Notes Each outlet connection in the work area has an individual cable run (link) from the TR. This represents a star topology shown in the diagram. This arrangement is most convenient for moves, adds and changes (MAC’s). Any horizontal cable link is limited to 90 meters in length. Locate the TR centrally on each floor to equalize cable run lengths. As a rule, use 40% max fill for cable pathways. Allow one work area per 100 sq. ft. of floor space for design purposes.

X The consolidation point must be mounted to a permanent building structure in an area free from obstructions or furniture. X Cross connections are not allowed in the consolidation enclosure. X Due to the effect of NEXT on multiple connections in close proximity, this standard recommends locating all consolidation points at least 15m (49 ft.) away from the TR. X Consolidation points and transition points cannot be combined in any single horizontal link. X Each consolidation point should serve a maximum of 12 work areas, with consideration for future growth. X Administration should follow the guidelines of ANSI/TIA-606-B. The MUTOA contains multiple telecommunications outlet connectors to service a cluster of individual work areas. X A combination of solid conductor 4-pair UTP cables and fiber optic cables may be run from the TR to the MUTOA. X The MUTOA is permanently mounted to a building structure that is in close proximity to a cluster of work areas. X A MUTOA allows horizontal cabling to remain intact when the open-office layout plan is changed. X Work area cables are either fiber patch cords or stranded conductor copper cords with a modular plug on each end. X Length of all work area cables from the MUTOA must be labeled on both ends. Maximum length is 20 meters for horizontal runs less than 70 meters. X Each MUTOA should serve a maximum of 12 work areas. X Administration should follow the guidelines of ANSI/TIA-606-B. tải về 0.82 Mb. Chia sẻ với bạn bè của bạn:
