Description
The AddOn Q28-100G-CWDM4X2-AO is an MSA- and TAA-compliant 2x100GBase-CWDM4 QSFP28-DD optical transceiver designed for high-performance data center, enterprise, metro, and access network applications. It delivers an aggregate data rate of 206 Gbps over single-mode fiber (SMF) with a maximum reach of 2 km using wavelengths from 1270 nm to 1330 nm via a CS duplex connector.
Featuring an 8x25G electrical interface and DFB-based CWDM transmitters, this transceiver ensures seamless network integration and compatibility. It includes Digital Optical Monitoring (DOM) for real-time diagnostics and is rigorously tested for data traffic performance and interoperability. With its compact QSFP28-DD form factor, low power consumption, and reliable performance, this module is ideal for scaling high-density 100G networks and beyond.
