WSP-Q40GLR4L-RF
QSFP 40G Ethernet - LR4 Lite, LC, 2KM REMANUFACTURED
Inventory quantities are subject to availability and are not guaranteed until the order is placed.
The Cisco WSP-Q40GLR4L-RF is a professionally remanufactured 40GBASE-LR4 QSFP+ transceiver module designed for extended-reach 40 Gigabit Ethernet connectivity over single-mode fiber in data center and enterprise network environments. This hot-pluggable optical module provides 40 Gbps throughput over distances up to 10 kilometers using duplex LC connectors and single-mode fiber, making it ideal for data center interconnects, campus backbone links, and metropolitan area network connections. The LR4 variant uses four lanes of 10G transmission over parallel single-mode fibers at 1310nm wavelength via CWDM technology for reliable long-distance performance.
This remanufactured transceiver has been thoroughly tested and certified to meet Cisco's quality standards. Each unit undergoes comprehensive testing including optical power measurement, bit error rate testing, temperature cycling, wavelength verification, and interoperability validation with Cisco switches and routers. The module features Digital Optical Monitoring (DOM) for real-time diagnostics of temperature, voltage, laser bias current, transmit power, and receive power. Compatible with Cisco Nexus, Catalyst, ASR, and other platforms supporting QSFP+ interfaces. Low power consumption (<3.5W typical) reduces operational costs. MSA-compliant design ensures broad compatibility. Three-year warranty with advance replacement support.
