Drawing 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 provide end-to-end DWDM devices including almost all optical components - from active modules to optical passive devices, such as optical amplifiers (EDFA & RFA), Mux & Demux, OPM, ROADM, MCS, OLP, and OTDR.
To meet the demand for mass data transmission in data centers, we have developed a series of high-speed optical modules with rates ranging from 10G to 800G, providing high-quality interconnection solutions.


Reliable and high-performance products using mature lasers and mainstream chip solutions. Solutions include Dark Fiber, WDM, Radio over Fiber, and High Speed back-haul for 4G/5G systems.
Comprehensive FTTx optical fiber access total solutions covering all-optical or combined access solutions for global communication network constructors.


Integrated optical line protection systems (OLP) and optical line monitoring systems (OLM) ensure the stable operation of communication lines.






As a specialized manufacturer of magnetic telecom and network components, we are certified by ISO9001:2000, RoHS, REACH, CE, and UL. Our facilities include advanced manufacturing and testing equipment. With abundant production capacity of 3000K per month, we ensure timely delivery. We design and sell a complete series of high-speed optical interconnection solutions for cloud computing and ultra-broadband networks worldwide.
