The US Transceivers compatible QSFP-40G-PSM4-AR is a high-performance 40GBASE-PSM4 QSFP+ transceiver module designed for single-mode fiber deployments requiring extended reach at 40Gbps. This module operates over eight single-mode fiber lanes (4 transmit, 4 receive) using an MPO/MTP connector interface, with each lane transmitting at 10Gbps for an aggregate data rate of 40Gbps. The nominal wavelength is 1310nm, supporting a maximum cable distance of 500 meters over OS2 single-mode fiber.
The US Transceivers compatible QSFP-40G-PSM4-AR is built to meet PSM4 MSA and IEEE 802.3 standards and is fully TAA compliant, making it suitable for government and regulated enterprise procurement. It supports Digital Diagnostic Monitoring (DDM/DOM) for real-time visibility into optical performance parameters including temperature, voltage, and optical power levels.
This module is an ideal solution for data center interconnects, campus backbone links, high-performance computing environments, and enterprise core networking applications where reliable 40G parallel single-mode connectivity is required.
