Overview
This Ethernet-over-VDSL system consists of end-user CPEs (Customer
Premise Equipment) connected to a VDSL switch by standard telephone
cable. The VDSL connection delivers an Ethernet data link while
simultaneously supporting standard telephone services. The system can be
deployed in any multi-dwelling/multi-tenant environment (apartment
blocks, hotels, or office complex) to provide both high-speed Internet
access and telephone services without any need for re-wiring.
The VDSL switch has a built-in POTS splitter that combines both the data
and phone signals coming from your Internet and telephone service
providers, and passes these signals directly over standard telephone wiring
to multiple users in the same building. A CPE is then used to separate
these signals and pass them on to a customer’s computer and telephone
equipment. Using the pre-defined profiles, in-building connections can
operate up to 100 Mbps upstream and downstream for runs up to 200
meters (656 ft).
Note:
Type-1 26 AWG (100 ohm)/0.4 mm, or Type-2 24 AWG (100
ohm)/0.5 mm cable may be installed to achieve the maximum
distance. However, typically 24 AWG (100 ohm)/0.5 mm wire
provides better performance than 26 AWG (100 ohm)/0.4 mm wire.
Note the distance may be limited by factors such as how the cable is
bundled, and the interference and noise on the link.
