CB-LC-LC-SMF15M=: What Is Its Function, Compatibility, and Why Choose Itmall.sale for Purchase?

​​Understanding the CB-LC-LC-SMF15M=​​

The ​​CB-LC-LC-SMF15M=​​ is a Cisco-certified ​​duplex single-mode fiber (SMF)​​ optic cable with LC connectors on both ends. Designed for ​​long-haul, high-speed data transmission​​, this 15-meter cable supports applications requiring low latency and high bandwidth over extended distances, such as data center interconnects (DCI) or metropolitan area networks (MAN). Its OS2-grade fiber ensures minimal signal attenuation, making it ideal for 10G/100G/400G Ethernet and telecom backbones.

​​Key Technical Specifications​​

• ​​Connectors​​: Duplex LC/LC, polished for low insertion loss (≤0.3 dB).
• ​​Fiber Type​​: OS2 single-mode fiber, optimized for ​​1310nm and 1550nm wavelengths​​.
• ​​Maximum Distance​​: Supports ​​10G up to 40km​​ and ​​100G up to 10km​​ (with appropriate transceivers).
• ​​Standards Compliance​​: Meets ​​IEEE 802.3​​, ​​ITU-T G.652​​, and ​​QSFP28​​ specifications.
• ​​Durability​​: Corning® SMF core with bend-insensitive design for rugged deployments.

​​Compatible Devices and Use Cases​​

The ​​CB-LC-LC-SMF15M=​​ is validated for use with:

• ​​Cisco Switches​​: Nexus 9000 Series (e.g., N9K-C9336C-FX2), Catalyst 9500/9600.
• ​​Transceivers​​: Compatible with ​​SFP+, QSFP28, CFP2​​, and ​​CFP4​​ optics.
• ​​Routers​​: ASR 9000 Series for high-speed WAN aggregation.

​​Primary Applications​​:

• Connecting data centers across campus or metro-area networks.
• High-frequency trading (HFT) setups requiring ultra-low latency.

​​Addressing Critical User Concerns​​

​​Q: Can this cable support 400G Ethernet?​​
A: Yes—when paired with ​​400G-FR4​​ transceivers, it supports 400G over 2km (using multiplexing).

​​Q: Is it compatible with older 1G SFP modules?​​
A: Yes, but ensure transceivers are OS2-rated for single-mode fiber.
