Zebra KT-CLMPT-RS507-01R Mounting Hardware and Stands

The Cisco QSFP-40G-LR4 supports 40 Gigabit Ethernet transmission over single-mode fiber with a maximum distance of approximately 10 kilometers (10KM). This long-reach capability makes it ideal for campus and metropolitan area network deployments where extended optical distances are required.

The Cisco QSFP-40G-LR4 uses LC duplex connectors and is designed for single-mode optical fiber connectivity. This configuration provides reliable, high-speed data transmission over extended distances compared to multi-mode fiber alternatives.

Yes, the QSFP-40G-LR4 is a hot-swappable transceiver module, allowing you to install or replace it without powering down your network equipment. This feature minimizes downtime during maintenance and upgrades in production environments.

The Cisco QSFP-40G-LR4 operates at a 1310 nm wavelength, which is optimized for long-reach transmission over single-mode fiber. This wavelength standard ensures compatibility with enterprise-grade optical networking infrastructure.

The QSFP-40G-LR4 is compatible with Cisco networking equipment that supports QSFP+ modules and 40GBase-LR4 standards. We recommend verifying your specific hardware specifications before purchasing. Contact us today to confirm compatibility with your infrastructure.

The 40G QSFP-40G-LR4 delivers 40 Gigabit Ethernet over 10km of single-mode fiber, while our 100G QSFP-100G-LR4-S-RF modules provide 100 Gigabit Ethernet at the same 10km distance. For ultra-long distances up to 80km, we offer the QSFP-100G-ZR4-S= module. Visit barcodesinc.com to compare all available transceiver options for your specific bandwidth and distance requirements.
