800G QSFP DD LPO 2DR4

LPO Linear Drive Pluggable Optical Original Product

It uses a linear drive strategy to replace DSPs with a Transimpedance Amplifier (TIA) and Driver Chip (DRIVER) with excellent linearity and EQ capabilities. These high-performance parts have been leveraged in leading module and system level designs and enable highly efficient interconnect spanning both short reach and long. An LPO (Linear Pluggable Optics) solution offers considerable power savings for optical interconnect by removing the digital signal processing (DSP) function from the pluggable optical module. This architecture takes advantage of the capabilities in each segment of the link to form a power, cost.

Columbia AOC Active Optical Cable LPO

Our AOCs feature DPO (fully retimed), low-power LRO (Linear-Receive Optics), and LPO (Linear-drive Pluggable Optics) designs, supporting data rates from 100G up to 800G across pre-specified lengths and form factors. AOC cables are high-speed cables that use optical fiber for transmission of data. This report examines the optical interconnect segments that have long served as data bridges between elements of large systems or clusters in communication networks and datacenters. Active Copper Cables (ACCs) are DAC copper cables but include a signal booster IC in the end to extend the length to 3, 4, and 5-meters depending on the speed. In the modern three-layer CLOS network architecture of data centers, the interconnection links between the Spine and Leaf layers, as well as between the Leaf and ToR (Top of Rack) layers, are generally limited to within 2 kilometers in length.

Solution Optical Transmitter LPO

The LPO solution completely removes the DSP from the module, shifting the signal processing function to the host-side SerDes. Its advantages include the lowest power consumption (30–50% lower than DSP), extremely low latency, and the lowest module BOM cost. From principles to applications, and compares it with traditional optical modules. Leveraging LPO technology, the module provides ultra-low-latency, power-efficient optical links tailored for AI, high-performance computing, and hyperscale data center applications. To address this, Macom and NVIDIA first proposed Linear-drive Pluggable Optics (LPO) in 2022. It uses a linear drive strategy to replace DSPs with a Transimpedance Amplifier (TIA) and Driver Chip (DRIVER) with excellent linearity and EQ capabilities.

Aero-optical electronic transmitter LPO

It uses a linear drive strategy to replace DSPs with a Transimpedance Amplifier (TIA) and Driver Chip (DRIVER) with excellent linearity and EQ capabilities. While copper cabling still offers cost and reliability advantages for short-distance connections, it faces the dual challenges of speed bottlenecks and cabling complexity in high-bandwidth, long-distance, and high-energy-efficiency scenarios. 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. In a power-constrained AI cluster or data center, every Watt of power that is used by the network is a Watt of power that cannot be allocated to compute.

Angola LPO Optical Module QSFP-DD

Infused with Linear-Drive Technology, it transforms short-range, high-bandwidth, low-power, and low-latency applications. With power consumption under 4W, significant cost savings, and reduced latency, this transceiver stands at the forefront of innovation.
