Overview of the CB-LC-LC-SMF1M=
The CB-LC-LC-SMF1M= is a Cisco-certified single-mode fiber (SMF) optic cable designed for high-speed, long-distance data transmission in enterprise and telecom networks. Featuring LC duplex connectors and a 1-meter (3.3-foot) length, it is ideal for short-range, high-density connections between routers, switches, or optical transceivers in data centers or equipment racks.
Key Technical Specifications
- Fiber Type: Single-mode fiber (OS2), optimized for long-haul communication with low signal attenuation.
- Connectors: Duplex LC/LC, ensuring compatibility with Cisco’s high-density transceivers (e.g., QSFP28, SFP+).
- Wavelength Support: 1310 nm and 1550 nm, suitable for 10G/40G/100G Ethernet, DWDM, and SONET/SDH.
- Cable Length: 1 meter, optimized for intra-rack or adjacent device connectivity.
- Standards Compliance: Meets ITU-T G.652, IEEE 802.3, and TIA-568 for performance and safety.
Common User Questions Answered
Q: Can this cable support 100G Ethernet?
A: Yes. When paired with Cisco QSFP28 transceivers, it supports 100G links over single-mode fiber.
Q: Why use single-mode fiber for a 1-meter cable?
A: While SMF excels in long-distance runs, the CB-LC-LC-SMF1M= is often used in high-density setups where future scalability or specific transceiver requirements (e.g., coherent optics) mandate SMF.
Q: Is it compatible with multi-mode fiber transceivers?
A: No. Single-mode and multi-mode fibers use different light wavelengths and core diameters. Always match fiber types to transceivers.
Typical Applications
- Connecting Cisco Nexus switches to CPAK/CFP2 coherent optics in data centers.
- Short-range DWDM links for wavelength-division multiplexing setups.
- Router-to-transceiver patching in high-performance networks.
Installation Best Practices
- Avoid excessive bending: Maintain a minimum bend radius of 30mm to prevent fiber damage.
- Clean connectors regularly: Use optical-grade cleaning tools to avoid signal loss from dust or debris.
- Label both ends: Simplify troubleshooting in dense cabling environments.
Where to Purchase the CB-LC-LC-SMF1M=
For guaranteed performance and compatibility, purchase the CB-LC-LC-SMF1M= from authorized suppliers like [“CB-LC-LC-SMF1M=” link to (https://itmall.sale/product-category/cisco/). Generic alternatives risk higher insertion loss or connector misalignment, leading to network instability.
Why Precision Matters in Fiber Optic Networks
During a data center deployment, a team used uncertified SMF cables to connect 100G switches, assuming all LC cables were interchangeable. The result? Intermittent link drops due to mismatched core alignment. Replacing them with the CB-LC-LC-SMF1M= resolved the issue immediately. This underscores a critical truth: even short fiber runs demand precision. Certified cables ensure exacting tolerances that generic options can’t match—crucial for maintaining uptime in high-stakes environments.
