Product Overview
The QSFP-40G-SR4-S is a high-performance 40 Gigabit QSFP+ optical transceiver module optimized for short-reach data transmission over multimode fiber. It supports a maximum distance of 100 meters on OM3 and up to 150 meters on OM4 fiber using an MPO-12 connector. Designed for high-density data centers, enterprise core networks, and cloud computing environments, this module offers cost-effective and energy-efficient 40G Ethernet connectivity.
Product Details
Operating over 4 parallel channels at a wavelength of 850 nm, the QSFP-40G-SR4-S transmits and receives simultaneously at 10 Gbps per channel, delivering an aggregate bandwidth of 40 Gbps. It uses an MPO interface and is designed for multimode parallel optics cabling infrastructure. The module is hot-swappable, supports Digital Diagnostics Monitoring (DDM), and complies with IEEE 802.3ba 40GBASE-SR4 standard.
