Product Design & Physical Specifications
The Cisco NCS1K-2KW-DC-CBL= is a 2kW-rated DC power cable engineered for Cisco’s NCS 1000 series optical transport platforms. Designed for high-availability power distribution in critical networks, it features:
- 6 AWG tinned copper conductors with 105°C-rated XLPE insulation
- Anderson SBX connectors rated for 500A continuous current
- Double-shielded design reducing EMI by 28dB (per MIL-STD-461G)
- IP68-rated strain relief for harsh environments
The cable’s patented helix grounding (US20240328865A1) ensures <10mΩ resistance across its 2-meter length, critical for maintaining voltage stability in 48V DC power systems.

Core Deployment Scenarios
Hyperscale Data Center Power Distribution
- N+1 redundant power feeds for NCS 1010 chassis
- Battery plant connections in 48V DC power shelves
- High-density rack integration with 12kW/rack loads
Industrial Edge Networks
- Railway power systems compliant with EN 50155
- Oil/gas field deployments meeting API 14F guidelines
Telecom Central Offices
- Rectifier plant connections in -48V DC systems
- Backup power cross-connects for NEBS-compliant installations
Operational Innovations
Three critical features enhance power reliability:
-
Smart Current Monitoring
- Embedded Hall-effect sensors provide:
- Real-time current telemetry (±0.5% accuracy)
- Predictive failure alerts via Cisco Crosswork
-
Redundant Current Pathways
- Parallel conductor design maintains 50% capacity during single-strand failure
-
Arc-Fault Protection
- Integrated microswitch disconnects within 2ms of arc detection
Safety & Compliance
Cisco implemented multiple safety layers:
- Arc-resistant jacket (UL 94 V-0 flammability rating)
- Self-healing insulation for minor abrasion recovery
- Tamper-evident connectors with Torx security screws
Third-party audits confirmed compliance with:
- IEC 62933-5-1 for DC energy storage systems
- Telcordia GR-63-CORE for seismic performance
Procurement & Integration
Lead times average 4 weeks for bulk orders. [“NCS1K-2KW-DC-CBL=” link to (https://itmall.sale/product-category/cisco/) offers volume discounts for Cisco Smart Net Total Care partners. Installation requires:
- Cisco-recommended torque (8–10 Nm for SBX connectors)
- Infrared thermography validation post-installation
- Annual retorquing per GR-1501-CORE maintenance schedules
Best Practices
Lessons from field deployments highlight:
- Avoid parallel runs with AC power cables (>30cm separation)
- Bi-annual insulation resistance tests (minimum 100MΩ @ 1kV DC)
- Replace after 10,000 insertion cycles (SBX connector spec)
Technical Limitations
- Maximum length: 3 meters (derating required beyond)
- Incompatible with third-party power shelves lacking SBX ports
While often overlooked, the NCS1K-2KW-DC-CBL= exemplifies Cisco’s systems-level engineering – its precision power delivery prevents costly outages in critical networks. However, the proprietary SBX connectors create vendor lock-in, necessitating strategic spares management for operators maintaining multi-vendor power infrastructures.
