Marvell has agreed to buy Lumentum, the San Jose-based maker of optical components, in a deal valued at $115 billion.

The two companies are not strangers. Marvell already purchases laser technology from Lumentum, so the acquisition would bring a key supplier in-house rather than add an unrelated business.

Why it matters

Lasers are a core building block of optical connections, which move data between servers and other equipment in data centers. By acquiring a supplier it already relies on, Marvell would gain direct control over a technology it currently buys from outside.

At $115 billion, the transaction ranks as a very large deal for the optical components sector and signals how much value is being placed on the hardware that connects data center systems.

What comes next

Further details, including the deal structure, financing and the timetable for closing, were not part of the initial information available. As with transactions of this size, the agreement would be expected to go through the usual approval processes before it can be completed.
