CB-LC-LC-MMF15M=: Why Is This Cisco Multimode Fiber Cable Ideal for Short-Reach Connectivity?

Overview of the CB-LC-LC-MMF15M=

The ​​CB-LC-LC-MMF15M=​​ is a ​​Cisco-certified multimode fiber optic cable​​ designed for high-speed, short-distance data transmission in enterprise networks. Featuring ​​LC duplex connectors​​ on both ends and a ​​15-meter length​​, it’s optimized for connecting switches, routers, or servers within data centers, wiring closets, or adjacent racks. Its OM3-grade fiber supports 10/40/100G Ethernet, making it a future-proof choice for bandwidth-intensive applications.

Technical Specifications

• ​​Connector Type​​: ​​LC-LC duplex​​, ensuring precise alignment for minimal insertion loss.
• ​​Fiber Type​​: ​​OM3 50/125μm​​, supporting ​​10G up to 300m​​ and ​​40/100G up to 100m​​.
• ​​Cable Length​​: ​​15 meters​​, ideal for intra-rack or cross-rack deployments.
• ​​Compatibility​​: Works with ​​Cisco SFP+, QSFP+, and QSFP28 transceivers​​ (e.g., Nexus 9000 Series).

Key Use Cases

​​Where does the CB-LC-LC-MMF15M= deliver value?​​

• ​​Data Center Interconnects​​: Links top-of-rack (ToR) switches to spine switches in ​​Cisco ACI fabric​​ architectures.
• ​​High-Performance Computing (HPC)​​: Supports low-latency communication between servers and storage arrays.
• ​​Video Production Networks​​: Enables uncompressed 4K/8K video transport over IP with ​​SMPTE ST 2110​​ standards.

Addressing Critical User Questions

​​Q: Can this cable replace single-mode fiber for 100G links?​​
A: For ​​short distances (<100m)​​, OM3 multimode is cost-effective. Single-mode is better for long-haul.

​​Q: Is OM3 backward-compatible with older 1G/10G transceivers?​​
A: Yes. OM3 works with ​​1G SFP​​, ​​10G SR​​, and higher-speed optics.

​​Q: How does LC duplex differ from standard LC?​​
A: ​​Duplex LC​​ pairs Tx/Rx channels in one connector, simplifying polarity management versus separate LC cables.

​​Q: Does bending affect performance?​​
A: The ​​aqua-colored jacket​​ and bend-insensitive fiber reduce loss even in tight cable trays.

Field Insights

During a data center upgrade, a client’s generic OM3 cable caused intermittent 40G link drops due to mismatched core alignment. The CB-LC-LC-MMF15M= isn’t just a cable—it’s a precision tool. For teams prioritizing uptime, this cable transforms “almost works” into “just works.” Cutting costs here might save pennies today but cost thousands in downtime tomorrow.
