Switchboard 100 Ohm Central Office
Switchboard 100 Central Office (CO) Cables are designed for indoor use in CO exchanges, or in premises telephone rooms. These cables are used for interconnection of distribution frames and digital switching and transmission equipment systems. Switchboard 100 provides 100 Ohm characteristic impedance. The product line consists of 24 or 26 AWG tinned insulated copper wires that are twisted into pairs. The pairs are stranded together utilizing a standard color code scheme.
Applications:
• T1/DS1
• T1C/DS1C
• 4 Mbps token ring (IEEE 802.5)
• 10 Mbps 10BASE-T ethernet (IEEE 802.3)
Features:
• 100 Ohm nominal Impedance
• Tinned copper conductors
• CMR listed
• Rip cord
• Band marked
Benefits:
• Impedance mismatch with Outside Plant (OSP) cables is minimized
• Minimize change in wire-wrap joint resistance
• Suitable for horizontal and riser installations
• Added ease of jacket removal
• Easy identification of conductor ring mates
