Long-Range QSFP-40G-LR4-S 40G Transceiver for Single-Mode Fiber
Product Overview
The QSFP-40G-LR4-S is a 40 Gigabit Ethernet QSFP+ optical transceiver designed for long-range data transmission over single-mode fiber (SMF). It supports distances up to 10 kilometers using LC duplex connectors and operates using 4 wavelengths in the 1310 nm band. This module is ideal for high-capacity data center interconnects, enterprise core layers, and carrier network backbones that require reliable, high-speed long-distance connectivity.
Product Details
Compliant with the IEEE 802.3ba 40GBASE-LR4 standard, the QSFP-40G-LR4-S utilizes four 10G lanes (CWDM) on the transmit and receive sides to deliver an aggregated 40 Gbps bandwidth. The module is hot-pluggable and supports Digital Diagnostics Monitoring (DDM), providing real-time monitoring of key operating parameters. It is engineered for power efficiency and optimal signal integrity in demanding 40G Ethernet applications.
