We draw on over 10 years of experience in chips and modules to integrate fast speeds, small size, power savings, and high performance in every module. We provide a full series of optical modules for fixed access, wireless access, carrier Ethernet, wavelength division multiplexing (WDM), and data communication networks.
We can provide end-to-end DWDM devices with almost all optical devices - from active modules to optical passive devices, including optical amplifiers (EDFA & RFA), Mux & Demux, OPM, ROADM, MCS, OLP, and OTDR etc.
To meet the demand of mass data transmission in data centers, we have developed a series of high-speed optical modules with product rates ranging from 10G to 800G, providing high-quality optical interconnection solutions for data centers.
We provide high reliability and performance products with mature and efficient lasers and mainstream chip solutions to our customers all around the world. The solution includes Dark Fiber, WDM, Radio over Fiber, High Speed, Mid-haul and Back-haul which could meet all the needs of various scenarios in 4G/5G systems.
Aimed at global communication network constructors, we provide FTTx optical fiber access total solutions covering all-optical or optical copper combined access solutions and products.
To ensure the normal operation of the communication line, we provide the optical cable O&M solution which integrates an optical line protection system (OLP) and an optical line monitoring system (OLM).
Advanced manufacturing facilities and test equipment imported from abroad guarantee superior product quality and operational stability.




We are a specialized manufacturer of magnetic telecom and networking components, certified by ISO9001:2000, ROSH, REACH, CE and UL, and equipped with advanced manufacturing facilities and testing equipment imported from abroad. Established in 1997, our present setup supports a staff of around 2000. With an abundant monthly production capacity of 3000K, we ensure fast delivery within short timeframes.
Furthermore, we provide an expansive series of optical modules suitable for fixed access, wireless access, carrier Ethernet, wavelength division multiplexing (WDM), and data communication networks. This range also covers high-speed optical interconnection systems designed for cloud computing and ultra-broadband networks. Guided by state-of-the-art optoelectronic technologies, we develop, manufacture, and market these products globally.
