Tyco Electronics has introduced the AMP NETCONNECT XG copper cabling system for 10-gigabit Ethernet applications.
This new twisted-pair system consists of PiMF (Pairs in Metal Foil) shielded cable, shielded connectors, and shielded patch-panel designs that overcome alien crosstalk (ANEXT) effects to fully support the proposed 10GBASE-T standard and enable 10 Gbit/s transmission over a full 100-metre channel.
The 10GBASE-T standard (IEEE 802.3an), currently under development, is targeting an operating frequency of 500 MHz. At this frequency, the signal integrity on existing unshielded (UTP) cabling systems is adversely affected by ANEXT.
Because today's active network equipment cannot cancel ANEXT, the distances over which TIA/EIA-568-B standard compliant UTP can support 10GBASE-T are greatly reduced. The AMP NETCONNECT XG copper cabling system incorporates an individual pair foil shielding that virtually eliminates ANEXT, resulting in a signal/noise ratio proven to support 10 Gbit/s Ethernet data rates over distances of up to 100 metres.
The AMP NETCONNECT XG copper cabling system has been tested to 625 MHz in worst-case scenario installations and has demonstrated a Shannon capacity of greater than 19 Gbit/s, nearly twice the capacity of existing Category 6 UTP systems.

There is an obvious need for the industry to be more energy efficient and pay more attention to the ways in which energy is both used and wasted. Do you think we have the products on the market to meet our needs?
