The US Transceivers compatible QDD-4X100G-LR is a 400G QSFP-DD optical transceiver engineered for high-density, long-reach network deployments. Operating as four independent 100G lanes over single-mode fiber, this module delivers an aggregate data rate of 400Gbps at a 1310nm wavelength and supports link distances up to 10km. It is designed as a drop-in compatible replacement for Juniper networks requiring the QDD-4X100G-LR specification.
Built to the QSFP-DD form factor, this transceiver utilizes four LAN-WDM wavelengths around 1310nm and employs 4x100G LR4 technology with LC Duplex connectivity. The module supports Digital Diagnostic Monitoring (DDM), providing real-time visibility into key optical parameters such as temperature, voltage, and optical power levels.
This US Transceivers compatible module is TAA compliant and fully tested to ensure interoperability and reliability in data center interconnect, enterprise core networking, and high-performance computing environments. It offers a cost-effective alternative without compromising performance or compliance.
