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 provide end-to-end DWDM device solutions including active modules and optical passive devices, such as optical amplifiers (EDFA & RFA), Mux & Demux, OPM, ROADM, MCS, OLP, and OTDR.
To meet the demand of 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 optical interconnection solutions.


Providing high reliability and performance with mature laser and mainstream chip solutions. This includes Dark Fiber, WDM, Radio over Fiber, High Speed, Mid-haul and Back-haul for 4G/5G systems.
Providing total optical fiber access solutions covered from all-optical or optical copper combined access solutions and products for global communication network constructers.






Our company is a specialized manufacturer of magnetic telecom and networking components, certified by ISO9001:2000, ROSH, REACH, CE and UL. We own advanced manufacturing facilities and test equipment imported from abroad. Established in 1997, we have around 2000 staff at present. With an abundant productive capacity of 3000K per month, we are able to deliver products within a short time.
Moreover, we provide a full series of optical modules for fixed access, wireless access, carrier Ethernet, wavelength division multiplexing (WDM), and data communication networks. The range also offers high-speed optical interconnection solutions for cloud computing and ultra-broadband networks.
