Drawing on over 10 years of experience in chips and modules, we 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.



Optical Transport Networks
We provide end-to-end DWDM devices including almost all optical components - from active modules to passive devices, such as optical amplifiers (EDFA & RFA), Mux & Demux, OPM, ROADM, MCS, OLP, and OTDR.
Cloud and Enterprise
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 interconnection solutions.
Wireless
High reliability and performance products with mature lasers and mainstream chip solutions. Solutions include Dark Fiber, WDM, Radio over Fiber, High Speed, Mid-haul, and Back-haul for 4G/5G systems.
FTTx
Aiming at global communication network constructors, we provide FTTx optical fiber access total solutions covering all-optical or optical copper combined access products.









We are a specialized manufacturer of magnetic telecom and networking components, certificated by ISO9001:2000, ROSH, REACH, CE and UL. Our facility owns advanced manufacturing and test equipment imported from abroad. With abundant productive capacity, we are able to deliver products within a short time. We develop, manufacture, and sell high-speed optical interconnection solutions for cloud computing and ultra-broadband networks around the world.
