Product Description

Extended Reach QSFP-40G-CSR4 Module for 40G Ethernet Over MMF

Product Overview
The QSFP-40G-CSR4 is an extended-range 40 Gigabit QSFP+ optical transceiver designed for high-speed, high-density data center and enterprise networking applications. It supports up to 400 meters over OM4 multimode fiber and 300 meters over OM3 fiber using MPO-12 connectors. This module uses 4 parallel lanes of 10 Gbps signals to deliver 40 Gbps total throughput and is fully compliant with IEEE 802.3ba 40GBASE-CSR4 standards.

Product Details
The QSFP-40G-CSR4 operates at a wavelength of 850 nm and is built for multimode fiber cabling. It uses 4 transmit and 4 receive channels and supports full-duplex operation. With low power consumption and Digital Diagnostics Monitoring (DDM), the module ensures reliable and scalable short- to mid-range 40G Ethernet connectivity. Ideal for data centers transitioning from 10G to 40G backbone infrastructure.
