QSFP-40G-LR4-S-RF

QSFP-40G-LR4-S-RF is a professionally remanufactured Cisco 40GBASE-LR4 QSFP+ transceiver module, designed to provide 40 Gigabit Ethernet connectivity over single-mode fiber in enterprise and data center environments. The module transmits up to 10 km over SMF using four wavelength-multiplexed lanes via LC duplex connectors, making it well-suited for long-reach inter-switch and aggregation layer links.

This remanufactured QSFP+ transceiver meets Cisco performance specifications and has been thoroughly inspected and tested prior to shipment. Validation includes optical transmit and receive power levels, wavelength accuracy across all four CWDM lanes, and hot-swap functionality with Cisco Catalyst and Nexus platforms.

Key Features:
• 40GBASE-LR4 standard compliance for 40 Gigabit Ethernet over single-mode fiber
• Four-lane CWDM architecture with wavelengths at 1271, 1291, 1311, and 1331 nm
• Supports link distances up to 10 km over OS1/OS2 single-mode fiber
• LC duplex fiber connector interface for standard SMF patch panels and cabling
• Hot-swappable QSFP+ form factor compatible with Cisco Catalyst 6500, Nexus 3000, 5000, 7000, and 9000 series
• "S" suffix denotes Cisco Spare designation, functionally identical to the standard QSFP-40G-LR4 module
