$1,898.50

SKU: QDD-4X100G-LR-S-US Categories: , , Brand:

The US Transceivers compatible QDD-4X100G-LR-S is a 400G QSFP-DD optical transceiver designed for high-density, long-reach network deployments. Operating across four 100G lanes using 1310 nm wavelength, this module delivers an aggregate data rate of 400 Gbps and supports link distances up to 10 km over single-mode fiber, making it well suited for data center interconnect and enterprise core applications.

Built to the QSFP-DD form factor, this transceiver uses an LC Duplex connector and 4x100G-LR electrical interface, compliant with IEEE 802.3cu and relevant MSA specifications. The module supports Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters including temperature, voltage, bias current, and optical power.

This US Transceivers compatible module is TAA compliant and manufactured to meet RoHS, CE, and REACH standards, providing a cost-effective, fully compatible alternative for use in qualifying network equipment without sacrificing performance or reliability.
