Product Details
The 1249C Series Central Office (CO) Cables are designed for use between switching and transmission equipment for distances up to 450 feet. With short twist lays, 1249C series offers superior crosstalk performance over standard telephone cable. It is manufactured with a dual foil shield for additional Electromagnetic Interference (EMI) reduction and is double jacketed for protection of the twisted pairs. The 1249C series meets or exceeds all applicable requirements of Telcordia® GR-137 specifications.
Features:
• 26 AWG tinned copper conductors
• Solid Polyolefin insulation
• 100 Ohm nominal Impedance
• Short pair lays/tight twists
• Dual aluminum foil shields
• Tinned copper drain wire
• CMR listed
• Rip cord
• Solid color insulation
Benefits:
• Small diameter and light weight result in smaller cable bundles and easier handling; minimize change in wire-wrap joint resistance
• Greater crush resistance and improved transmission characteristics
• Impedance mismatch with OSP cable is minimized
• Improved crosstalk performance and pair identification
• Higher EMI isolation over a single foil shield
• Easier termination and superior grounding
• Suitable for horizontal and riser installations
• Added ease of jacket removal
• Easy identification of conductor ring mates
