CB-LC-LC-MMF10M= – Why Is This Cisco Fiber Cable a Cornerstone of High-Speed Data Center Deployments?



Understanding the CB-LC-LC-MMF10M=

The ​​CB-LC-LC-MMF10M=​​ is a Cisco-certified duplex multimode fiber (MMF) patch cable designed for short-range, high-bandwidth connections between network devices. Featuring ​​LC-LC connectors​​ and a 10-meter length, it’s optimized for data centers, enterprise backbone links, and storage area networks (SANs) requiring low-latency, high-reliability performance.

Key specifications:

  • ​Fiber type​​: OM3/OM4 50/125µm multimode.
  • ​Maximum data rate​​: 10Gbps at 550 meters (OM4).
  • ​Connector polish​​: UPC (Ultra Physical Contact) for reduced insertion loss (<0.3 dB).

Technical Advantages Over Generic Fiber Cables

  • ​Cisco Validated Design (CVD) compliance​​: Ensures ​​zero compatibility issues​​ with Cisco Nexus 9000/3000 Series switches and UCS Fabric Interconnects.
  • ​Bend-insensitive fiber​​: Tolerates tight bends (radius as low as 7.5mm) without signal degradation, ideal for cable-dense racks.
  • ​Flame-retardant jacket​​: Meets ​​IEC 60332-3-24​​ standards for fire safety in plenum spaces.

Addressing Critical User Concerns

​Q: Can this cable support 25G/40G Ethernet?​
A: Yes—using ​​Cisco QSFP-40G-SR4​​ transceivers, it supports 40G over OM4 up to 150 meters. For 25G, pair with SFP-25G-SR optics.


​Q: How does OM4 differ from OM3 in real-world use?​
A: OM4 reduces insertion loss by ​​15%​​ and extends 10G reach from 300m (OM3) to 550m. For 10m connections, OM4 future-proofs upgrades to higher speeds.


​Q: Is this cable suitable for outdoor installations?​
A: No—the ​​CB-LC-LC-MMF10M=​​ lacks UV-resistant jacketing. For outdoor use, consider Cisco’s ​​CPC-LC-LC-MMF10M=​​ with armored shielding.


Where to Purchase Reliable CB-LC-LC-MMF10M= Cables

For guaranteed performance and Cisco’s limited lifetime warranty, source this cable from itmall.sale, a certified provider of Cisco optical networking solutions.


Practical Insight

In data center environments, ​​fiber integrity is non-negotiable​​. While generic OM4 cables might save $50 upfront, the CB-LC-LC-MMF10M=’s CVD certification eliminates troubleshooting hours spent on CRC errors or auto-negotiation failures. Having debugged countless link flapping issues traced to off-brand fibers, I’ll always prioritize Cisco’s engineered tolerances over marginal cost cuts.
