In the optical cable materials sector, the company holds a leading position in the industry, with products including optical fiber cable filling compounds, PBT, and PBT color masterbatches. For optical communication devices, the company offers two major product series: passive and active. In passive products, it has established three core technology platforms—planar lightwave circuits (PLWCs), micro-optics, and micro-electro-optical systems (MEOS)—enabling the production of a full range of optical splitters, AWG (arrayed waveguide grating) devices, DWDM/LWDM/MWDM/CWDM modules based on TFF technology, and MEMS VOAs. Active products include optical components, high-speed optical modules for 5G fronthaul, and other optical transceiver modules. Leveraging its comprehensive technological portfolio and product lines, the company delivers diverse solutions for the optical communications industry. Its primary products are categorized into four major groups: optical integrated products, optical components, JinSen products, and optical materials.
