T100 Series Central Office
The T100 Series Central Office (CO) Cables are designed for use between switching and transmission equipment for distances up to 450 feet. They are manufactured with a longitudinal aluminum-polyester foil shield with aluminum facing the jacket for additional Electromagnetic Interference (EMI) reduction. The pairs are stranded together utilizing distinctive colored insulation in combination with markings of colored ink. The outer jacket is a gray flame retardant PVC. T100 series meets or exceeds all applicable requirements of Telcordia GR-137 specifications.
Applications:
• T1/DS1
• T1C/DS1C
Features:
• 24 AWG tinned copper conductors
• CMR listed
• Solid PVC insulation
• 100 Ohm nominal impedance
• Standard pair lays
• Longitudinal aluminum/polyester foil shield with aluminum facing the jacket
• CMR listed
• 24 AWG tinned copper drain wire
• Rip cord
• Band marked
Benefits:
• Small diameter and light weight result in smaller cable bundles
and easier handling; tinned copper conductors minimize
change in wire-wrap joint resistance
• Suitable for horizontal and riser installations
• Greater crush resistance and improved transmission characteristics
• Impedance mismatch with Outside Plant (OSP) cables is minimized
• Improved crosstalk performance and pair identification
• EMI isolation
• Easier termination and superior grounding
• Added ease of jacket removal
• Easy pair identification
