Nexans offers LAN cabling solutions
achieving multi-gigabit data speeds The
benefits of LANmark Class E: Performance Full Cat 6 on channel and components Nexans is the first in the industry to offer complete Category 6/Class E performance of the full 4 connector channel using RJ45 connectivity as well as on the separate components, as specified in the most recent ISO/IEC working drafts (Feb. 2000). Definitions A permanent link is the fixed part of the cabling, which is to be tested after installation, and which gives information on installation quality. The
permanent link extends from patch panel at the cabinet side to the
Telecommunications Outlet at the user side. The link can optionally contain a Consolidation Point which makes it possible to allow for open office cabling environments, allowing freedom of including an extra patch facility at a multi-user outlet. The permanent link excludes work area and equipment cords and cross-connections. These three connections (PP, TO and CP) contribute to the worst case model of the permanent link. The channel configuration has been defined for application purposes. It represents the complete end-to-end path between user equipment (PC, phone, printer, video equipment ...) and the active equipment at the cabinet side (switch, hub, PABX, video equipment ...) The channel includes the patchcords at both sides and allows for an extra cross connection at the cabinet side. This cross connection is in certain environments desirable in order to allow or facilitate patching. The
worst case configuration that has to be taken into account for full ISO/IEC
compliance therefore includes the 90 m of horizontal cable, 4 connectors
and a total of 10 m of patchcords. Full 4 connector channel: why is it important Today some installations claim Class E performance using only two non compliant Category 6 connectors. However in the event that a future active device would necessitate additional patching, then these systems may not have sufficient headroom to perform and could fail. To ensure that worst case future scenarios can be achieved, it is necessary to have both a compliant channel and compliant components. This enables a free choice of the preferred system configuration that can be adapted if necessary to accommodate future moves and changes. The LANmark Class E solution uses fully compliant Cat 6 components throughout.
Nexans is the first (and today the only company) to offer a 4 connector RJ45 based Class E system providing improved flexibility over non-RJ 45 solutions. All components comply with the Cat6 requirements, and the Channel respects full 4 Connector Class E. Moreover, the LANmark Class E 4-connector model provides extra headroom on top of the standard requirements, delivering improved throughput and efficiency today with room to grow tomorrow.
