Is Cohr an optical module

Cohr (Coherent Corp.) is not itself an optical module, but the company manufactures optical modules, including coherent optical transceivers and co-packaged optics solutions.Coherent Corp. (NYSE: COHR) is a global photonics company that produces a wide range of products, including optical modules, industrial lasers, and photonics materials . The company's optical modules include coherent optical transceivers, which are used in high-bandwidth data communications and AI-driven data centers . These modules leverage technologies such as silicon photonics, indium phosphide (InP) lasers, VCSELs, and advanced packaging to deliver high-speed, energy-efficient optical interconnects . Coherent's optical modules are designed for hot-pluggable applications, with electrical interfaces connecting to the system and optical interfaces connecting to fiber networks. They support coherent modulation formats like BPSK, QPSK, and QAM, which are essential for high-capacity data transmission . The company also develops co-packaged optics (CPO) modules, which integrate optical components closely with networking hardware to reduce latency and power consumption in next-generation data centers . In summary, while Cohr itself is the company, it is a major manufacturer of optical modules and related photonics technologies, playing a key role in AI-scale data center networks and high-speed optical communications .
