As AI and high-performance compute networks scale to 400G, 800G, and 1.6T, power consumption and latency become increasingly important. Linear Pluggable Optics (LPO) and Linear Receive Optics (LRO) reduce or remove DSP-based signal processing within the optical module, helping support lower-power, lower-latency connectivity across next-generation network architectures.
AddOn offers LPO and LRO solutions across OSFP, OSFP224, and QSFP112 form factors. Available as MSA-compliant or OEM-compatible options, the portfolio supports leading network platforms from Arista, Cisco, Juniper, Nvidia, and Mellanox.
Why LPO & LRO?
