Cisco C9300L-48T-4X-E=: What Defines Its Role
Technical Profile and Core Specifications T...
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.
