600C Series Central Office
The 600C Series Central Office (CO) Cables are designed for use between switching and transmission equipment for distances up to 650 feet. This series offers the lowest attenuation of all the CO cable products by using 22 AWG conductors. It is manufactured with a dual foil shield for additional Electromagnetic Interference (EMI) reduction. The 600C series meets or exceeds all applicable requirements of Telcordia GR-137 specifications.
Applications:
• T1/DS1
• T1C/DS1C
• DS2
Features:
• 22 AWG tinned copper conductors
• Solid Polyolefin insulation
• 100 Ohm nominal Impedance
• Dual aluminum foil shield
• Tinned copper drain wire
• CMR listed
• Rip cord
• Band marked
Benefits:
• Low attenuation, enabling longer run length; tinned copper conductors minimize change in wire-wrap joint resistance
• Greater crush resistance and improved transmission characteristics; smaller cable over dual insulated type
• Impedance mismatch with Outside Plant (OSP) cables is minimized
• Higher EMI isolation over a single foil shield; smaller cable diameter than 600B Series cables
• Easier termination and superior grounding
• Suitable for horizontal and riser installations
• Added ease of jacket removal
• Easy identification of conductor ring mates
