Does JCET Group count as an optical module

JCET Group, a leading semiconductor assembly and test (OSAT) company, has expanded its capabilities to include optical modules and co-packaged optics (CPO) technologies. Their CPO solutions integrate optical engines, which consist of photonic integrated chips (PICs) and electronic integrated chips (EICs), with ASICs on a single substrate using advanced packaging techniques . This integration enables shorter optical paths, higher bandwidth, improved signal integrity, and optimized thermal management, making it suitable for high-performance computing, data centers, and AI applications . JCET's optical engine packaging includes photodetectors, optical waveguides, high-speed modulators, drivers, and trans-impedance amplifiers, supporting heterogeneous integration and system-level reliability . The company has partnered with multiple customers to provide packaging integration, thermal management, and reliability verification for optical modules, demonstrating its active role in the optical interconnect ecosystem . By leveraging its advanced semiconductor packaging expertise, JCET is positioned to deliver next-generation optical solutions that enhance bandwidth density, reduce latency, and improve energy efficiency compared to conventional pluggable optical modules . This confirms that JCET Group is not only involved in optical modules but is also a key player in the development and integration of highly integrated optical systems.
