Home / ODM Single-fiber Bidirectional LPO
It enables Ethernet-like links with 1, 2, 4, or 8 lanes for data centers, using low power, high port density, low cost, and low latency pluggable transceiver modules in form factors such as QSFP, QSFP-DD, and OSFP. The 100G-DR-LPO specification by the LPO (Linear Pluggable Optics) MSA defines 100 Gb/s/lane 53. 125 GBd PAM4 optical interfaces, optical links using standard single-mode fiber with up to 500 m reach, and host-module electrical interfaces for hosts with DSP based SerDes and RS(544,514) FEC. Mountain View, CA – August 18, 2025 – Lightmatter, the leader in photonic (super)computing, today announced a groundbreaking achievement in optical communications: a 16-wavelength bidirectional Dense Wavelength Division Multiplexing (DWDM) optical link operating on one strand of standard. Traditional OLP protects 4-core optical fiber, but in many places, due to insufficient optical fiber resources, it is impossible to provide excessive optical fiber resources and optical line redundancy protection. According to the LPO MSA, an LPO solution offers power savings for optical interconnect by removing the digital signal processing (DSP) function from the pluggable optical module.
This specification is a significant milestone for both the LPO MSA and networking industry. The 100G-DR-LPO specification has been validated by extensive member interoperability
