A Faster Future with Linear Pluggable Optics

LPOs are a low-power pluggable module interface that eliminates DSP chips, creating a linear signal path. By simplifying the connection, the LPO reduces cost, latency, and power consumption. The LPO MSA (Linear Pluggable Optics Multi-Source Agreement) Group announced the completion of the 100 Gb/s per lane Linear Pluggable Optics Single-Mode Optical Data Transmission specification, or 100G-DR-LPO. 100G-DR-LPO targets speeds of up to 800 Gigabit Ethernet required for AI and machine learning applications, and can be used in networking and computing equipment such as switches and network interface cards (NICs). QSFP, QSFP-DD, and OSFP are possible form factors, with compatibility with SMF connectors.
