Description
The AddOn QSFP28-100GB-LR-CW27-AO is a high-performance, MSA-compliant 100GBase-CWDM optical transceiver designed for next-generation data center, metro, and enterprise network applications. Operating at a 1270nm wavelength over single-mode fiber (SMF), this module delivers up to 10km of data transmission with FEC, providing reliable and cost-effective connectivity for high-bandwidth environments.
Built to 100G Lambda MSA 100G-LR specifications, it supports a 4x25G electrical interface and features Digital Optical Monitoring (DOM) for real-time performance diagnostics. The module’s low power consumption (< 4.5 W), LC duplex connector, and robust design make it ideal for high-density networking deployments. It is also TAA-compliant, RoHS-certified, and undergoes rigorous testing to ensure seamless interoperability with OEM equipment.
