The AddOn MSA Compliant QSFP28-100GB-FR-AO is a high-performance 100-Gigabit transceiver engineered for intermediate-reach optical connectivity in data centers and enterprise networks. This module delivers 100GBase-FR throughput at 106.25 Gbps over Single-mode Fiber (SMF), supporting distances up to 2 km (1.24 miles). Utilizing advanced Single Lambda PAM4 modulation technology at 1310nm wavelength, it transmits 100G data over a single optical wavelength, significantly reducing complexity and power consumption compared to traditional 4-lane technologies. The duplex LC connector interface ensures straightforward installation and reliable optical connectivity. Digital Optical Monitoring (DOM) support enables real-time performance tracking for proactive network diagnostics and optimal uptime. As an MSA Compliant module, it is designed to work seamlessly across a wide variety of open hardware platforms without vendor-specific locking, providing a flexible and cost-effective alternative to OEM-branded optics. With power consumption under 4.5W and a compact hot-swappable QSFP28 form factor, this transceiver is ideal for high-density data center deployments and network infrastructure upgrades requiring dependable 100-Gigabit optical connectivity.
