The US Transceivers compatible JH233A is a 40GBASE-eSR4 QSFP+ transceiver module designed for high-density 40 Gigabit Ethernet applications. Operating over OM3 or OM4 multimode fiber with an 850nm VCSEL array, this module supports extended short-reach distances of up to 300 meters on OM3 and 400 meters on OM4, making it well suited for campus and data center environments where greater reach than standard SR4 is required.
This module uses an MPO/MTP connector interface and parallel optics architecture across four lanes, delivering 10Gbps per lane for an aggregate data rate of 40Gbps. It features Digital Diagnostic Monitoring (DDM) for real-time visibility into key performance parameters including optical power, temperature, and voltage.
The US Transceivers compatible JH233A is TAA compliant and manufactured to meet IEEE 802.3 and QSFP+ MSA standards, ensuring reliable interoperability in enterprise networking, high-performance computing, and data center interconnect deployments.
