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 covered from 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).
