Dorelink
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. Providing a full series of optical modules for fixed access, wireless access, carrier Ethernet, wavelength division multiplexing (WDM), and data communication networks.
Providing end-to-end DWDM devices with almost all optical devices - from active modules to optical passive devices, including optical amplifier (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.
High reliability and performance products with mature and efficient lasers and mainstream chip solutions. Includes Dark Fiber, WDM, Radio over Fiber, High Speed, Mid-haul and Back-haul for 4G/5G systems.
Total optical fiber access solutions covered from all-optical or optical copper combined access solutions and products for global communication network constructers.
