In the data center, there are two transmission solutions, parallel and WDM. In the current 100G data center, short-distance optical modules use more parallel technology，and WDM technology are widely used in long-distance transmission. What is parallel optics technology? What is WDM optics technology? With 23 years manufacturing experience of passive optical devices, HYC has professional optical simulation and analysis capabilities, and the back-end processing workshop is equipped with complete set of cutting and testing equipment, which can provide various customized high-precision optical subassemblies either with parallel optics technology or WDM optics technology for high-speed transceivers.
