The US Transceivers compatible QDD-4X100G-FR is a 400G QSFP-DD optical transceiver designed as a direct replacement for the Juniper QDD-4X100G-FR. Operating over single-mode fiber with four 100G lanes using 1310 nm wavelength optics, this module delivers an aggregate data rate of 400 Gbps and supports link distances up to 2 km, making it well suited for high-density data center and metro interconnect deployments.
Built to the QSFP-DD MSA and IEEE 802.3cu standards, this module utilizes four independent lanes of 100GBASE-FR1 optics via a single MPO/MTP connector interface. Each lane operates at 106.25 Gbps using PAM4 modulation. Digital Diagnostic Monitoring (DDM) provides real-time visibility into temperature, voltage, bias current, and optical power levels for simplified network management.
The US Transceivers compatible QDD-4X100G-FR is TAA compliant and manufactured to meet or exceed OEM specifications for interoperability, reliability, and performance in enterprise core, data center interconnect, and high-speed aggregation applications.
