STC-QSFP56-SR4-100M – 200G QSFP56 SR4 100m Transceiver

High-speed 200Gbps QSFP56 SR4 transceiver for short-reach multimode fiber applications – up to 100m

Product Overview

The STC-QSFP56-SR4-100M optical transceiver is designed for 200Gbps Ethernet transmission over multimode fiber (MMF) up to 100 meters. It operates over four parallel lanes of 50Gbps PAM4-modulated signals using 850nm wavelength. Fully compliant with IEEE 802.3cd 200GBASE-SR4 and QSFP56 MSA standards, this low-power, high-bandwidth module is ideal for hyperscale data centers, cloud networks, and enterprise backbone applications requiring ultra-fast and short-distance links.
