Tyrone was awarded the Eircom VDSL2 project in 2008, for the design, manufacture, integration and supply of street-side cabinets. The trial network consisted of 50cabinets, with 1200more units required in the Dublin region. The rollout shall continue throughout Ireland.
Tyrone is now supplying many other customers with cabinet solutions for VDSL2 projects. VDSL2 (Very High Speed Digital Subscriber Line 2) is an access
technology that exploits the existing infrastructure of copper wires that were originally deployed for POTS (Plain Old Telephone) services. It can be deployed from central offices, from fibre-fed cabinets located near the customer premises, or within buildings.
VDSL2 is the newest and most advanced standard of DSL broadband wireline communications. Designed to support the wide deployment of Triple Play services such as voice, video, data, high definition television (HDTV) and interactive gaming, VDSL2 enables operators and carriers to gradually, flexibly, and cost efficiently upgrade existing xDSL-infrastructure.
It has been standardized as ITU G.993.2. VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at 'source' to 100 Mbit/s at 0.5 km (1640 ft) and 50 Mbit/s at 1 km (3280 ft), but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1.6 km (1 mile) its performance is equal to ADSL2+. ADSL-like long reach performance is one of the key advantages of VDSL2. LR-VDSL2 enabled systems are capable of supporting speeds of around 1-4 Mbit/s (downstream) over distances of 4 to 5 km (2 to 3 miles), gradually increasing the bit rate up to symmetric 100 Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1 systems, are not limited to short local loops or MTU/MDUs only, but can also be used for medium range applications.
