Question · Q1 2026
Harsh Kumar asked if the strong 1.3 book-to-bill ratio was primarily driven by the data center segment or other components. He also inquired if MACOM's data center gross margins are below the corporate goal of 60% and sought an update on the Linear Pluggable Optics (LPO) business, including commercial revenues and its potential market size/TAM for MACOM over the next 2-3 years.
Answer
Jack Kober, CFO, confirmed significant strength in the data center book-to-bill for the December quarter but generally does not break out book-to-bill by end market. He stated that gross margins vary across MACOM's product portfolio, declining to give specific data center margin numbers. Stephen G. Daly, President and CEO, expressed bullishness on LPO, noting three hyperscalers are embracing it and are in various production phases for 800G modules (100G per lane). He expects LPO to evolve to NPO/CPO, acknowledging it's currently a small market but compelling due to power savings. He also highlighted customer interest in LRO at 1.6T using 200G per lane chips, suggesting LRO is more likely to emerge first at 1.6T than LPO.
