Cable-stayed bridge are as follows: There are four major classes of rigging on cable-stayed bridges: "mono", "harp", "fan," and "star". There are also four arrangements for support columns: "single", "double", "portal" and "A-shaped". Depending on the design, the columns may be vertical or angled or curved relative to the bridge deck. A side-spar cable-stayed bridge uses a central tower supported only on one side. This design allows the construction of a curved bridge. Far more radical in its structure, the Puente del Alamillo (1992) uses a single cantilever spar on one side of the span, with cables on one side only to
Category 6 cable is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100 meter maximum distance as previous Ethernet variants. Cat 6 cable can be identified by the printing on the side of the cable sheath. Cable types, connector types and cabling topologies are defined by TIA/EIA-568. Cat 6 patch cables are normally terminated in 8P8C modular connectors. Connectors use either T568A or T568B pin assignments; performance is comparable provided both ends of a cable are terminated identically. If Cat 6 rated patch cables, jacks and connectors are not used with Cat 6
