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:

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.

Vistabeam is another example of a company finding a way to serve the often-overlooked rural market. Matt and Monique Larsen, who co-founded Vistabeam in 2004, believed rural communities deserved better internet and better opportunities. Like other entrepreneurs who rose during the early days of the internet, the Larsens were working at another ISP, but saw an opportunity to leverage new wireless technology with a local hands on focus that a national provider can’t offer.

Vistabeam has continued to grow. Today, its network covers 50,000 square miles and serves more than 100 towns across western Nebraska, northeastern Colorado, and southeastern Wyoming — the region it calls Wyobraskarado. The company maintains that its differentiator is not technology, but rather “its heart.” The company is family-owned, locally operated, and committed to creating good jobs in the communities it serves.

Opening

0:05 Introduction of our guest

0:28 Vistabeam’s broadband journey Matt Larsen talks about how Vistabeam has evolved since its founding in 2004. 2:36 Fixed wireless and fiber How Vistabeam is leveraging fixed wireless and fiber to bring broadband to rural areas of Nebraska, northeastern Colorado, and southeastern Wyoming. 4:27 Weighing fiber and wireless options Vistabeam sees fiber and wireless as being a tool that fits specific situations.

5:52 The competitive landscape While Vistabeam faces a mix of traditional rural telcos and competitors, the company says its value lies in its local and responsive approach. 7:19 Middle Mile Vistabeam has built its own middle mile networks with microwave and available fiber to backhaul traffic. 9:19 Fiber broadband expansions The service provider has been leveraging state grants to build fiber in Kimball, Mitchell and Oshkosh, Nebraska.

12:18 Business service options Vistabeam is being opportunistic with business services, which are resonating with tractor dealerships and others. 14:27 Final Thoughts/closing
