Suspension bridge construct special towers, as the buildings can anchor the cables. Cable suspension may also be augmented by the inherent stiffness of a structure that has much in common with a tubular bridge. Typical suspension bridges are constructed using a sequence generally described as follows. Depending on length and size, construction may take anywhere between a year and a half (construction on the original Tacoma Narrows Bridge took only 19 months) up to as long as a decade (the Akashi-Kaikyō Bridge's construction began in May 1986 and was opened in May 1998 – a total of twelve years). Suspension bridges are
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
