Description
Belden 734C12 008 is a DS3/DS4 central office coax cable with 12 coaxes, designed for 734/735 telecommunications systems, switchboard communications, and central office wiring. It features RG-59 construction with 20 AWG solid silvered copper conductors and a 75 Ohm nominal characteristic impedance. The design includes PE - Polyethylene (Foam) insulation, a Duofoil® tape shield plus an 85% tinned copper braid, and PVC inner and outer jackets in Gray. It is rated CMR for indoor riser installations and has a UL Voltage Rating of 300 V (CMR, CMG).
Belden 734C12 008 Key Features
- This 12-coax DS3/DS4 central office coax design supports multi-channel central office interconnect needs.
- RG-59 construction uses 20 AWG solid, 0.032 in, SC - Silvered Copper conductors.
- A 75 Ohm nominal characteristic impedance supports DS3/DS4 signal transmission.
- Shielding includes Duofoil® tri-laminate tape (Alum+Poly+Alum) at 100% plus an 85% tinned copper (TC) braid.
- PVC - Polyvinyl Chloride inner and outer jackets are Gray; each inner jacket is gray and numbered.
- The cable is CMR rated for indoor - riser installations.
Belden 734C12 008 Applications
- Use it for central office wiring where multiple coax runs are needed in a single cable for organized routing.
- It is designed for DS3/DS4 interconnect links in central office environments.
- In 734/735 telecommunications systems, it supports central office connectivity.
- It fits switchboard communications wiring where consistent coax interconnections are required.
