Which manufacturer makes Finisar optical modules

Finisar optical modules are manufactured by II-VI Incorporated, following its acquisition of Finisar in 2019.Finisar Corporation, originally founded in 1987, specialized in optical communication components and subsystems, including optical transceivers, optical engines, active optical cables, and various optical modules for high-speed data transmission . In September 2019, II-VI Incorporated, a global leader in engineered materials and optoelectronic devices, completed the acquisition of Finisar for $3.2 billion, integrating Finisar's product lines into its photonics and compound semiconductor business segments . Under II-VI, Finisar optical modules continue to serve data centers, metro networks, long-haul transmission, and high-speed interconnect applications. These modules include technologies such as SFP, SFP+, QSFP, CFP transceivers, and DWDM modules, supporting data rates from 1 Gbps up to 400 Gbps . The modules utilize components like laser chips, photodetector chips, and silicon photonics chips, sourced from leading global suppliers or developed in-house to meet high-performance requirements . This acquisition positioned II-VI as a global leader in optical communications, combining Finisar's expertise in optical modules with II-VI's capabilities in engineered materials and optoelectronics, enabling more integrated solutions for networking, telecommunications, and data center applications . In summary, II-VI Incorporated is the company that now manufactures Finisar optical modules, maintaining the brand's legacy in high-speed optical communication technologies.
