Low-Density WDM (LWDM) Module: Compatible with CWDM/DWDM Ecosystems​

Shanghai Honghui Optical Communication Tech Corp was founded in 2001, focusing on the research and development, production, and sales of optical cable materials and optical communication devices. In the field of optical cable materials, the company is in a leading position in the industry, with products including fiber optic cable filling paste, PBT and PBT color masterbatch, etc; Optical communication devices include passive and active product series.

In terms of passive products, the company has established three major technology platforms, including planar optical waveguides, micro optics, and micro optoelectronics. The planar optical waveguide platform covers all processes of optical splitters, array waveguide gratings (AWGs) from chips to packaging, and can produce a full range of multi-channel heated/non heated AWGs for optical splitters and WDM systems; Micro optical platform products include DWDM, LWDM, MWDM, CWDM and other devices and modules based on TFF (Thin Film Filter) technology; Micro electromechanical platform products mainly include MEMS VOAs.

In terms of active products, they include optical devices, high-speed optical modules for 5G transmission, and other optical transceiver modules.

In the process of rapid growth, the company has successively passed the certification of quality, environment, safety, health and other systems, and has won multiple honors, such as "Demonstration Enterprise of the National Industrial Strong Foundation Project One stop Application Plan", "Key High tech Enterprise of the National Torch Plan", "National Specialized, Refined, Unique and New Small and Medium sized Enterprise", "Shanghai Specialized, Refined, Unique and New Small and Medium sized Enterprise", "Shanghai High tech Enterprise", "Shanghai Manufacturing Industry Single Champion", "Shanghai Innovative Enterprise", "Shanghai Enterprise Technology Center", "Shanghai Intellectual Property Advantage Enterprise", "Shanghai Famous Brand Enterprise". Its related products have been recognized as "National Key New Products" and "Shanghai Key New Products".

The company is committed to becoming a world-class optical communication system supporting service provider, with high-quality customers such as Huawei, ZTE, FiberHome, Changfei, Hengtong, Zhongtian, Futong, China Mobile, China Telecom, China Unicom, Corning, Guhe, Molex, Prysmian, etc. We have established a comprehensive international sales network, and our products are exported to countries such as Europe, America, and Southeast Asia, with a strong development momentum. The company has a sound business model and management system, providing a broad development platform for every employee.

The company acquired Shanghai Guanglian Communication Technology Co., Ltd. in 2021, becoming the first domestic enterprise capable of mass producing a full range of WDM filters. It has established production lines for coating, polishing, scratching, cleaning, and testing, including optical coating, optical cold processing, fiber coupled laser modules, and optical components. In the same year, a wholly-owned subsidiary, Jiangxi Honghui Optical Devices Co., Ltd., was established to expand the research and production of optical passive devices mainly based on PLC splitters and WDM wavelength division multiplexers, and obtained ISO9001, 45001, and 14001 system certificates the following year. Honghui Guangtong has become the only company in China that possesses both planar waveguide technology and high-end optical coating technology, effectively promoting the localization of high-end optical devices and core technologies in China.
