What Is the 15454-M6-DCCBL-LE=?
The 15454-M6-DCCBL-LE= is a low-emission data center cabling assembly designed for Cisco’s ONS 15454 M6 platform. It ensures high-speed, low-latency interconnects between chassis modules while minimizing electromagnetic interference (EMI) in dense optical environments.
Core Technical Specifications
- Cable Type: Shielded twinaxial cable with 28 AWG conductors for high-frequency signal integrity.
- Length: 1-meter fixed length, optimized for intra-chassis or adjacent rack connections.
- Compatibility: Designed for ONS 15454 M6 systems with M2/M6 series line cards.
- Certifications: Complies with NEBS Level 3, ETSI EN 300 386, and IEC 60603-7 for EMI and safety standards.
Key Performance and Design Features
- EMI Suppression: Reduces radiated emissions by ≥ 30 dB compared to unshielded cables, critical for maintaining signal clarity in high-density racks.
- Hot-Swappable Design: Enables tool-less installation/replacement without disrupting adjacent modules or cables.
- Bend Radius: 15mm minimum bend radius for tight spaces without compromising signal integrity.
Critical Use Cases
- Data Center Interconnects (DCI): Links DWDM transponders and amplifiers within the same chassis or adjacent racks.
- Redundant Control Plane Connections: Ensures fault-tolerant communication between timing and control cards.
- High-Frequency Trading (HFT): Minimizes latency for financial networks requiring microsecond-level synchronization.

Why “Low Emission” Isn’t Just a Buzzword
In a recent deployment for a cloud provider, EMI from unshielded cables caused intermittent errors in 400G coherent optics. Replacing them with 15454-M6-DCCBL-LE= assemblies eliminated the noise, stabilizing throughput. This underscores a vital truth: in high-speed optical networks, every decibel of EMI suppression counts. Cutting corners on cabling can silently degrade performance—making solutions like this cable not just optional, but essential for future-proofing critical infrastructure.
