Rtxm191 550 H3c
Overview
Product sourcing insights & recommendations
The RTXM191-550 is a 1.25G SFP (Small Form-factor Pluggable) optical transceiver module, primarily compatible with H3C and WTD networking equipment. It is typically used for 1000BASE-SX Gigabit Ethernet applications, supporting distances up to 550m over multi-mode fiber (MMF) at an 850nm wavelength FsOpticalmodulemanufacturers. Key technical features include a duplex LC connector, Digital Diagnostic Monitoring (DDM) support, and a low power consumption of under 0.8W FsOpticalmodulemanufacturers.
Market Trends and Insights (2026)
The global optical transceiver market is undergoing a major shift driven by AI infrastructure and high-speed data center demands.
- Market Growth & AI Drivers: The total market is projected to reach approximately $17.15 billion in 2026, with AI-specific data center transceivers alone expected to grow to $26 billion by the same year Fortunebusinessinsights100Gmodules.
- Speed Transitions: While legacy 1G/10G SFPs like the RTXM191 series remain common in enterprise networks, the market is rapidly moving toward 800G and 1.6T modules for AI GPU fabrics 100GmodulesLightcounting.
