Inventory quantities are subject to availability and are not guaranteed until the order is placed.
The QSFP-40G-LR4-S-RF is a professionally remanufactured Cisco 40GBASE-LR4 QSFP+ transceiver providing 40 Gigabit Ethernet connectivity over single-mode fiber using four CWDM wavelengths multiplexed onto a single LC duplex fiber pair. Supporting link distances up to 10km over OS2 single-mode fiber, this transceiver is the standard choice for inter-building and campus backbone 40G links where single-mode fiber infrastructure is already deployed. The S designation indicates Cisco's standard variant validated across Cisco Nexus, Catalyst, and ASR platforms supporting QSFP+ interfaces.
This remanufactured 40GBASE-LR4 QSFP+ meets Cisco's optical performance and wavelength accuracy specifications and has been thoroughly tested for transmit power across all four CWDM lanes, receive sensitivity, and platform compatibility. Each unit is validated for use in Cisco Nexus 9000, 7000, 5000, 3000, Catalyst, and ASR platforms supporting standard QSFP+ LR4 interfaces.
Key Features:
• 40GBASE-LR4 over single-mode fiber using four multiplexed CWDM wavelengths
• Up to 10km reach over OS2 SMF for inter-building and campus backbone links
• LC duplex connector for standard single-mode fiber patch cable connectivity
• Compatible with Cisco Nexus 9000, 7000, 5000, 3000, and Catalyst platforms
• Digital optical monitoring for per-channel signal quality diagnostics
• Hot-swappable QSFP+ module for non-disruptive field replacement
This refurbished transceiver is ideal for enterprises and service providers deploying 40G single-mode fiber backbone links on Cisco switching and routing infrastructure. By choosing a remanufactured Cisco QSFP-40G-LR4-S, you deploy extended-reach 40G optical connectivity at substantially lower transceiver cost than new hardware.
