The US Transceivers compatible JH231A is a high-performance 40GBASE-SR4 QSFP+ transceiver module designed for short-reach parallel multimode fiber applications. Operating over an MPO/MTP interface with four transmit and four receive lanes at 850 nm, this module delivers an aggregate data rate of 40 Gbps and supports link distances up to 150 meters over OM4 multimode fiber (100 meters over OM3).
Built to meet IEEE 802.3ba and QSFP+ MSA standards, the US Transceivers compatible JH231A is fully TAA compliant and supports Digital Diagnostic Monitoring (DDM) for real-time visibility into key performance parameters including temperature, voltage, and optical power levels.
This module is an ideal drop-in replacement for use in data centers, enterprise core networks, and high-density switching environments, delivering reliable 40G connectivity with broad compatibility across QSFP+-capable platforms.
