Amphenol on Monday entered a $10.5 billion deal to buy CommScope's connectivity and cable solutions unit, the largest purchase by the fibre-optic cable maker that would make it a key player in the market for U.

A boom in artificial intelligence and heightened demand for data centers has boosted Amphenol’s business as more companies seek to use its products. The CCS deal would be Amphenol’s largest acquisition to date.

If an Amphenol-CommScope deal sounds familiar, that's because this is the second such deal that Amphenol has pursued in the past year.
