LR-LINK QSFP+ 40Gbps transceiver module for 40G Ethernet, supporting up to 10km transmission on single-mode fiber.
High-density data center interconnects often struggle with signal integrity and power consumption when scaling to 40G speeds. The LRFQ1340-10ATL addresses these challenges by providing a low-power, high-performance QSFP+ solution that maintains signal quality over extended distances without requiring complex cooling infrastructure.
This transceiver operates at a total data rate of 40Gb/s using four 10.3125Gb/s lanes with CWDM wavelengths. With a maximum power dissipation of only 2.5W and support for commercial temperatures from 0℃ to +70℃, it ensures energy-efficient operation while delivering consistent throughput for demanding network applications.
Ideal for 40G Ethernet deployments in enterprise and cloud environments, this module complies with IEEE 802.3ba standards and SFF-8436 specifications. Its ability to transmit up to 10km makes it a versatile choice for connecting buildings or campus networks, offering a robust alternative to copper solutions for long-reach 40G links.
Supports 40Gb/s data rate via 4x10Gb/s CWDM channels for high-bandwidth applications.
Enables transmission distances up to 10km on single-mode fiber, suitable for campus networks.
Low power consumption of ≤2.5W reduces operational costs and heat generation in dense racks.
Fully compliant with IEEE 802.3ba and SFF-8436 standards ensuring broad compatibility.
Designed for easy installation and replacement without system downtime.
