As bandwidth demand accelerates and power consumption issues become more acute, the emergence of Linear Pluggable Optics (LPO) has become a welcome technology. LPO is a technology that creates low-power optical modules for ultra-short-reach data center connections by removing the complex DSP (Digital Signal Processor) chip from the module. This design reduces power consumption, cost, and latency, making it ideal for AI clusters and hyperscale data centers. Industry standards groups have focused on two main developments: electrical interface standards and testing and optical link performance and deployment. The Optical Internetworking Forum (OIF) is moving forward with electrical interface standards while the LPO Multi-Source Agreement (LPO MSA) is addressing optical link performance and deployment challenges. In this podcast, we talked with Mark Kimber, the senior principal product definition specialist for Semtech. Here’s a timeline of the episode:
Opening
0:05 Host introduces guests Broadband Pulse host Sean Buckley introduced Kimber to the program.
0:38 LPO’s emergence Mark Kimber addresses emergence of LPO and Semtech’s role.
1:54 The LPO Multi-Source Agreement (MSA) How the new LPO MSA is establishing a specification and a methodology to make LPO work.
3:40 LPO standards efforts How the LPO MSA and the Optical Internetworking Forum (OIF) call for creating optical and electrical standards.
4:56 Semtech’s direct edge portfolio Semtech’s LPO platforms can help data center providers accommodate AI’s new power, latency and size requirements.
6:31 LPO plug and play operations Plug-and-play is key to help simplify large data center operations and management.
11:04 OIF’s Common Management Interface Specification (CMIS) role CMIS manages the LPO module's diagnostic capabilities, including monitoring the optical and electrical interfaces. 11:35 200G per lane technology How LPO can save power at higher speeds like 200G per lane. 14:10 Final Thoughts/Closing Mark Kimber offers his final thoughts on LPO.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
