15454-M6-DCCBL-LE=: How Does It Enhance Cisco ONS 15454 M6 Connectivity? Features, Compliance, and Applications

​​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​​

1. ​​EMI Suppression​​: Reduces radiated emissions by ​​≥ 30 dB​​ compared to unshielded cables, critical for maintaining signal clarity in high-density racks.
2. ​​Hot-Swappable Design​​: Enables tool-less installation/replacement without disrupting adjacent modules or cables.
3. ​​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.

​​Procurement and Compatibility Notes​​

​​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.
