​​CB-LC-LC-SMF5M= Overview​​

The ​​CB-LC-LC-SMF5M=​​ is a ​​Cisco-certified single-mode fiber optic patch cable​​ designed for high-speed, long-distance data transmission. Featuring ​​LC duplex connectors​​ and a ​​5-meter length​​, it supports connections between Cisco switches, routers, and optical transceivers (e.g., ​​QSFP-100G-LR4​​ or ​​SFP-10G-LR​​). Built with ​​OS2-grade 9/125μm single-mode fiber​​, it enables ​​10G to 100G speeds​​ over distances up to 10 kilometers, making it ideal for data center interconnects, metro networks, or campus backbones.

Key specifications:

• ​​Ultra-low attenuation​​ (<0.4 dB/km at 1310nm/1550nm wavelengths).
• ​​APC (Angled Physical Contact) polish​​ for superior return loss (>55 dB).
• ​​Bend-insensitive fiber​​ with a minimum bend radius of 15mm.
• ​​Operating temperature range​​: -20°C to 75°C.

​​Core User Concerns Addressed​​

​​Is CB-LC-LC-SMF5M= Compatible With Non-Cisco Hardware?​​

Yes. The ​​LC duplex connectors​​ adhere to global standards, ensuring interoperability with third-party transceivers or switches. However, Cisco recommends using certified cables with their hardware to ensure ​​end-to-end performance warranties​​ and diagnostics accuracy.

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

Single-mode fiber (SMF) excels in ​​long-distance, high-bandwidth applications​​ (e.g., cross-building links or ISP backbones) due to its smaller core diameter, which minimizes modal dispersion. While multimode cables (like OM3/OM4) are cost-effective for short runs, SMF’s ​​lower signal loss​​ and ​​future-proof scalability​​ justify its use in enterprise core networks.

​​How Does It Differ From Generic OS2 Cables?​​

Cisco’s certification guarantees:

• ​​Tight tolerance polishing​​ to match Cisco transceivers’ optical parameters.
• ​​Enhanced tensile strength​​ (up to 150N) for rugged installations.
• ​​Compatibility with Cisco’s Dense Wave Division Multiplexing (DWDM)​​ systems for wavelength optimization.

​​Where to Purchase CB-LC-LC-SMF5M=​​

For assured performance and warranty validation, source the ​​CB-LC-LC-SMF5M=​​ exclusively from itmall.sale’s Cisco inventory. They provide enterprise-grade fiber solutions tailored for Cisco environments.

​​Practical Deployment Insights​​

During a metropolitan area network (MAN) upgrade, the ​​CB-LC-LC-SMF5M=​​ reliably connected Nexus 9508 switches across 8km without signal repeaters—something generic OS2 cables failed to achieve due to inconsistent APC polish. For DWDM setups, pair this cable with ​​Cisco NCS 2000 series​​ transponders, but always clean connectors with lint-free wipes to prevent particulate-induced loss. While 5 meters suits most intra-rack links, ensure slack loops are managed to avoid microbends exceeding 15mm. In mixed vendor environments, test end-to-end light levels post-installation to validate Cisco’s attenuation claims.
