CB-LC-LC-MMF25M=: Why Is This Cisco Fiber Cable a Go-To for High-Speed Data Center Connectivity?

Overview of the CB-LC-LC-MMF25M=

The ​​CB-LC-LC-MMF25M=​​ is a ​​25-meter duplex multimode fiber optic cable​​ designed for short-range, high-bandwidth connections in data centers. Featuring ​​LC-LC connectors​​, it supports high-speed data transmission between Cisco switches, routers, and storage systems. Its OM3-grade fiber ensures compatibility with ​​10G, 40G, and 100G Ethernet​​ standards over short distances.

Key Technical Specifications

• ​​Length​​: 25 meters (82 feet).
• ​​Connectors​​: Duplex LC/LC (male), polished for low insertion loss.
• ​​Fiber type​​: ​​OM3 multimode​​ (50/125µm), optimized for 850nm VCSEL laser sources.
• ​​Bandwidth​​: Supports up to ​​10 Gbps at 300 meters​​ or ​​100G SR4 at 100 meters​​.

Compatibility and Use Cases

A common user question is whether this cable works with non-Cisco devices. While LC connectors are universal, the CB-LC-LC-MMF25M= is tested for seamless integration with Cisco hardware, including:

• ​​Nexus 9000/3000 series switches​​ (e.g., N9K-C93180YC-EX).
• ​​UCS C-Series servers​​ with Fibre Channel or Ethernet interfaces.
• ​​MDS 9000 storage switches​​ for SAN connectivity.

​​Note​​: For 40G/100G speeds, pair with ​​QSFP+ or QSFP28 transceivers​​ (e.g., QSFP-40G-SR4).

Addressing Data Center Deployment Challenges

​​Q: Can this cable be used for outdoor or long-distance runs?​​
No. OM3 fiber is designed for ​​indoor, short-reach applications​​ (≤100m for 100G). For outdoor or longer distances, use single-mode fiber with appropriate transceivers.

​​Q: Does it support legacy 1G/2G connections?​​
Yes, but OM3 fiber is overkill for 1G. Consider cost-effective OM1/OM2 cables for Gigabit-only setups.

Why Source CB-LC-LC-MMF25M= from itmall.sale?

[“CB-LC-LC-MMF25M=” link to (https://itmall.sale/product-category/cisco/).

itmall.sale provides ​​Cisco-certified OM3 cables​​ with factory-terminated connectors to ensure ≤0.3dB insertion loss. Counterfeit cables often have misaligned ferrules, causing signal degradation and CRC errors in high-speed links.

Best Practices for Optimal Performance

• ​​Bend radius​​: Maintain ≥10x the cable diameter to avoid microbending losses.
• ​​Cleaning​​: Use LC-specific cleaning tools to prevent dust-induced attenuation.
• ​​Labeling​​: Tag both ends to simplify troubleshooting in dense patch panels.

Final Insights

In an era where data center agility hinges on reliable physical layer components, the CB-LC-LC-MMF25M= stands out for its balance of performance and durability. While cheaper alternatives might save upfront costs, they risk unplanned downtime—a far costlier scenario. For enterprises prioritizing seamless 40G/100G migrations, investing in certified cables from trusted suppliers like itmall.sale isn’t just prudent; it’s foundational to maintaining competitive edge in data-driven industries.
