Finisar Corporation, founded in 1988, is headquartered in Sunnyvale, California, and is a global leader in optical communications. It designs, manufactures, and sells optical transceivers, active optical cables, optical engines, and other components for data centers, enterprise networking, and telecom networks. The company pioneered many pluggable optical module technologies, including SFP, SFP+, QSFP, CFP, and CFP2 form factors, which have become industry standards. Its broad product portfolio includes VCSEL-based modules, DFB lasers, EMLs, and high-speed transceivers supporting data rates from 1G to 800G and beyond. Finisar also offers advanced optical sensors and components for industrial and consumer applications. With an annual R&D expenditure of nearly $200 million, Finisar holds over 1,000 U.S. patents, more than 50 Chinese patents, and hundreds of pending applications worldwide. The company operates manufacturing and R&D facilities in the United States, Malaysia, China, and other locations. Finisar is recognized as the world’s largest supplier of pluggable optical modules, holding a leading market share in data center connectivity. In 2019, Finisar was acquired by II-VI Incorporated (now Coherent Corp.), expanding the combined entity’s capabilities across the photonics spectrum. Today, the Finisar brand continues to represent cutting-edge optical solutions for hyperscale data centers, 5G infrastructure, and high-performance computing.
