Category 5 Multipair Cables
Category 5 25-Pair Cable is constructed of 24AWG (0.5mm) solid-copper conductors insulated with high density
polyethylene. The insulated conductors are tightly twisted into pairs, stranded into mini-units. The cable employs a unique
honeycomb core construction. This design consists of multiple 3-Pair and 4-Pair tightly braided sub-units. A total of seven
uncovered sub-units (six around one) are then braided to encompass the cable core. This construction allows for easy pair
identi!cation and subsequent termination.
Category 5 25-Pair Cable provides excellent high-speed transmission, certi!ed to 155MHz and supports applications such as
155Mb/s ATM, 622Mb/s ATM and IEEE 802.3 1000 Base-T (Gigabit Ethernet) standards, using parallel transmission
technology or as a high performance voice riser cable.
Category 5e 25-Pair Cable allows the use of multi-pair cables in interconnect and zone cabling applications. The 25-pair
cable construction reduces tray and conduit !ll rates whilst allowing high-density interconnections.
