​CB-LC-LC-MMF3M= Overview​

The ​​CB-LC-LC-MMF3M=​​ is a ​​Cisco-certified multimode fiber optic patch cable​​ designed for high-speed data transmission in enterprise networks. Featuring ​​LC duplex connectors​​ on both ends and a ​​3-meter length​​, it supports short-range connections between Cisco switches, routers, and storage or server hardware. Optimized for ​​OM3-grade 50/125μm fiber​​, it delivers bandwidth up to ​​10 Gbps​​ over 300 meters, making it ideal for data centers, campus backbones, and high-density racks.

Key specifications:

  • ​Low insertion loss​​ (<0.5 dB) and ​​high return loss​​ (>20 dB) for signal integrity.
  • ​Bend-insensitive fiber​​ with a minimum bend radius of 7.5mm.
  • ​Shielded design​​ to reduce EMI/RFI interference in electrically noisy environments.
  • ​Operating temperature range​​: -10°C to 70°C.

​Addressing Key User Concerns​

​Is CB-LC-LC-MMF3M= Compatible With Non-Cisco Devices?​

Yes. The ​​LC duplex connectors​​ adhere to industry standards, ensuring compatibility with third-party switches, SFPs, or media converters. However, Cisco recommends using certified cables with their hardware to maintain ​​warranty compliance​​ and performance guarantees.


​Why Choose OM3 Multimode Over Single-Mode Fiber?​

OM3 multimode fiber is cost-effective for ​​short-distance, high-bandwidth applications​​ (e.g., intra-rack or inter-rack links). Single-mode cables excel in long-haul scenarios but require pricier transceivers. The ​​CB-LC-LC-MMF3M=​​ balances performance and affordability for sub-100-meter deployments.


​How Does It Differ From Generic OM3 Cables?​

Cisco’s certification ensures:

  • ​Precision-terminated connectors​​ with UPC polish for minimal signal reflection.
  • ​Tensile strength​​ up to 100N, reducing breakage risk during installations.
  • ​Compatibility with Cisco’s QoS and diagnostics tools​​, aiding in link troubleshooting.

​Where to Purchase CB-LC-LC-MMF3M=​

For guaranteed authenticity and Cisco warranty coverage, purchase the ​​CB-LC-LC-MMF3M=​​ exclusively from itmall.sale’s Cisco inventory. They specialize in high-performance fiber solutions for enterprise networks.


​Deployment Insights​

In a recent hyperscale data center rollout, the ​​CB-LC-LC-MMF3M=​​’s bend tolerance proved critical in cable-dense Nexus 9000 switch racks. Unlike generic OM3 cables, its connectors seated firmly into QSFP-40G-SR4 transceivers without intermittent link drops. For 40/100G deployments, pair this cable with ​​Cisco MDS 9700 directors​​ or ​​UCS fabric interconnects​​, but verify OM3’s distance limits—10G is reliable at 300m, but 40G drops to 100m. Always inspect connectors for dust before plug-in; even Cisco’s robust design can’t bypass contamination-induced attenuation.
