Description
The Cisco WSP-Q40GLR4L is a 40GBASE-LR4-Lite QSFP transceiver designed for reliable short-reach 40-Gigabit Ethernet connectivity over single-mode fiber. Operating at 1310 nm across four wavelengths, this module supports link distances of up to 2 kilometers using standard duplex LC connectors.
Built for data center, enterprise core, and service provider environments, the WSP-Q40GLR4L delivers a cost-effective alternative to full LR4 optics while maintaining interoperability with standard 40GBASE-LR4 interfaces. Its low power consumption and extended link budget make it ideal for high-density deployments where efficiency and performance are critical.
