Appendix D Cable Specifications
This appendix provides fiber and twisted-pair copper cable specifications.
Fiber Cable

: 9 μm
Multimode fiber
(recommended):
62.5/125 μm
Multimode fiber
(optional)
: 100/140, 85/140, 50/125 μm
T1/E1 Cable
Category 3: (minimum requirement)
Connector: RJ-48C
Electrical network connection: Single 4-wire (Tip/Ring - Tip1/Ring1)
Mechanical arrangement: 8-position miniature modular jack
Usage: 1.544 Mb/s access lines
Interface codes: 04DU9 (any applicable)
Cable types:
Long Haul T1/E1: 0db, -7.5dp, -15db, -22db
E1: E1 3.0V, 120 ohm
J1: 0-655’, 110 ohm (future support)
DSX-1: 0-133’, 133-266’, 266-399’, 399-533’, 533-655’, 100 ohm
Twisted-Pair Copper Cable
Twisted pair connection requires two active pairs. The two active pairs in a T1/E1 network are pins 1 & 2
and pins 4 & 5. Use only dedicated wire pairs (such as blue/white & white/blue, orange/white &
white/orange) for the active pins. Category 3 or better twisted-pair copper wire is required. Either
shielded twisted-pair (STP) or unshielded twisted-pair (UTP) can be used.
T1 TP/UTP
Gauge 24 to 22 AWG
Attenuation 2.6 dB/100 meters @ 1.0 MHz

±10%
E1 TP/UTP
Gauge 24 to 22 AWG
Attenuation 2.6 dB/100 meters @ 1.0 MHz
