These
cables are designed for subscriber
access digital networks at the remote
voltage supply of up to 500V d.c.
The basis of all structures is pair
twisting of conductors (the twisted
pair principle). The proposed structures
combine the features required of low
pair-count communication cables for
subscriber access digital networks,
and the characteristics of Class 5
LAN cables, providing a wide range
of resistance values (copper conductor
diameters of 0.40mm; 0.52mm; 0.64mm;
0.90mm).
All this allows to:
(see
references)
- Achieve, in 100-300 meter long
sections, the transfer of data at
the rate of 100 Mbit/s, or digital
stream transfer at the rate of 2 Mbit/s;
- Ensure subscriber access (compression)
using xDSL technologies in sections
of up to 7 km (conductor diameter
0.64mm) or up to 12 km ( conductor
diameter 0.90mm) without regenerators;
- Provide for broadband access in
distribution networks from the distribution
device to the subscriber;
- Use the cable for conventional telephone
communication in urban, corporate,
and rural communication networks,
IP-telephony, and security/fire alarm
systems.
- Use twisted pairs for subscriber
wiring inside buildings and save on
higher-grade cabling.
The products are sized in such a
way as to ensure digital access and
õDSL compression for subscriber lines
where such cable grades as ÒÐÏ, Ï274Ì,
or ÏÐÏÏÌ were earlier used. The ÒÖÏìÏï
2õ2õ0,90 cable grade is, by design,
a cheaper analogue of the ÊÑÏÏ cable
(where ÊÑÏÏ cables can be used without
armor).
All
single-pair cables have declarations
of conformity registered with the
Federal Communication Agency.
