Arris Pitch: Stop That Noise

12/14/2007 7:00 PM Eastern

Arris Group signed an exclusive deal with British broadband-equipment supplier Technetix Group to resell Technetix products in the United States that reduce the amount of upstream-channel noise on cable networks.

Arris's TeleWire Supply division will sell “Regal by Technetix” splitters, taps, in-home active and in-home networking products as part of its portfolio of Regal drop materials.

Noise — which in this context means interference to a radio-frequency signal as it moves from one place to another — is particularly prevalent in the 5 to 40 Megahertz spectral band used by cable system operators to send signals from subscribers' homes to headends.

So-called ingress noise can degrade available bandwidth and lead to cable-modem outages.

According to Technetix, its Ingress Safe technology can improve carrier-to-noise ratio of upstream signals by between 4 and 6 decibels (dB) when deployed in 50% or more of the subscriber drops in a node.

Technetix Group, based in Burgess Hill in England, has almost 200 employees worldwide. Its Americas subsidiary, Technetix Inc., is based in Englewood, Colo.
