TP Cables

Draka - UC900 SS27 Cat.7 S/FTP 4P LSHF Colour: xx

P/N: UC900-SS27-4P-xx

Technical data

Application
IEEE 802.3: 10Base-T; 100Base-T; 10GBase-T, ISDN; xDSL
IEEE 802.5 16 MB; ISDN; TPDDI; ATM155Mbit/s
The conductor diameter is smaller compared to the standard installation cables. This leads to an increased attenuation and therefore the
operating distance is reduced (60 m instead of 90 m installation cable in standard permanent link).

Standards
IEC 61156-6 work area cable
ISO/IEC 11801 2nd ed.
EN 50173-5
EN 50288-4-2

Flame resistance
PVC IEC 60332-1
LSHF-FR IEC 60332-3-24
IEC 60754-2; IEC 61034

Construction:
Conductor stranded bare copper wire Ø 0.42 mm (AWG 27/7)
Insulation
Foam Skin Polyethylene, Ø 0.98 mm
Twisting
2 cores to the pair
Pair screen
 Al-laminated plastic foil
Cable lay up 4 pairs (PiMF) to the core
Screen
Copper braid, tinned
Sheath
PVC or LSHF, color see “Technical data”
