Certified OSFP optical module LPO

OSFP LPO (Linear Pluggable Optics) modules are certified high-speed optical transceivers designed for power-efficient, low-latency, and interoperable connectivity in modern data centers and AI/ML networks.

Overview of OSFP LPO Technology

LPO (Linear Pluggable Optics) modules remove the traditional digital signal processing (DSP) from the pluggable module, using a linear architecture with TX-side linear drivers and RX-side TIAs. This design reduces power consumption and latency while maintaining pluggable flexibility, making it ideal for high-speed Ethernet links starting at 100 Gb/s per lane and scaling up to 1.6T . LPO modules leverage silicon photonics PICs for compact, high-speed, and reliable connectivity . OSFP (Octal Small Form Factor Pluggable) is a high-density form factor supporting 400G, 800G, and emerging 1.6T speeds. OSFP modules provide wide thermal envelopes and improved airflow, critical for AI cluster deployments and high-performance computing networks . They are compatible with multiple Ethernet speeds, including 100GE, 200GE, 400GE, and 800GE, and support high port density in 1RU switch configurations .

Certification and Standards Compliance

Certified OSFP LPO modules comply with multiple industry standards to ensure interoperability and reliability:

• OSFP MSA: Defines mechanical, electrical, and optical specifications for OSFP modules .
