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.
Product Features
Supports 40 Gigabit Ethernet via 4 x 10G parallel lanes
Extended short reach: up to 300 m (OM3) and 400 m (OM4)
Operates at 850 nm wavelength over multimode fiber
MPO-12 connector for parallel optics architecture
Digital Diagnostics Monitoring (DDM) support
Hot-pluggable QSFP+ form factor
Low power consumption (typically ≤ 1.5W)
Compliant with IEEE 802.3ba 40GBASE-CSR4 standard
