Low Skew, Category 6, 4-24 AWG pairs, CMR (Category 6 Cable) – Belden (7989R)

Features & Benefits

• Improve Crosstalk Performance: Central spline separates pairs and maintains stable pair position
• Optimized Cable Balance: Improved balance of transmission performance for simultaneous parallel transmission protocols
• Performance Reliability: Guarantees across all parameters, including insertion loss and crosstalk, for excellent uptime, headroom and network speeds
• Withstand Installation Rigors: Bonded-Pair Cables handle higher pulling tensions and tighter bend radii
• Easy, Mess-free Outdoor Installations: Dry Core Outside Plant and Indoor/Outdoor Plenum cables contain no inconvenient water-blocking gels, tapes, or powders
