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.
