Description
The AddOn Q28-100GP4-BXU2931-20-AO is a high-performance QSFP28 optical transceiver designed to deliver 100GBase-BX LR1 connectivity over single-mode fiber (SMF) with a maximum reach of 20 km. Operating on a single lambda with 1291 nm transmit and 1311 nm receive wavelengths, this module supports PAM4 modulation and is compliant with QSFP28 MSA and SFF-8636 Rev 2.10a standards. Featuring a 4×25 Gbps electrical interface compliant with OIF CEI-28G-VSR, it enables seamless integration into high-speed data center, enterprise, and carrier network environments.
Built with bidirectional LC connectors and digital optical monitoring (DOM), the transceiver allows for real-time diagnostics of optical performance and operating parameters. It operates on a single 3.3 V power supply within a commercial temperature range (0 °C to 70 °C), ensuring reliable performance. TAA-compliant and RoHS-certified, this transceiver meets the stringent requirements for government and enterprise deployments, and comes backed by AddOn’s limited lifetime warranty for long-term network assurance.
