FAQ
The 100G QSFP28 LR1 Single Lambda 20KM LC Optical Transceiver is a high-performance, long-reach module engineered for data center interconnects (DCI), 5G transport networks, and enterprise backbone links. Featuring a single-lambda architecture compliant with IEEE 802.3cu, it simplifies fiber deployment compared to traditional LR4 solutions, while delivering reliable 20km transmission over standard single-mode fiber (OS2/SMF).
This hot-swappable QSFP28 module integrates an EML laser transmitter with a PIN photodiode receiver, providing 100Gbps aggregate bandwidth through 4×25.78Gb/s channels using NRZ electrical signaling. With KP4 FEC support, the module ensures error-free transmission over long distances. Digital Diagnostic Monitoring (DDM) allows real-time tracking of key operational parameters, including Tx/Rx power, bias current, and temperature, facilitating stable network performance and proactive maintenance.
Designed for commercial and industrial environments, this transceiver operates efficiently on a single +3.3V power supply, supporting 0–70°C for commercial use and -30–85°C for industrial deployment. Fully compliant with QSFP28 MSA, 100G Lambda MSA LR1, SFF-8636, SFF-8679, and RoHS standards, it provides a reliable, energy-efficient solution for high-speed optical networking.
