LAN WDM Modules are a type of passive wavelength division multiplexing technology that enable the transmission of multiple optical signals over a single fiber optic cable. These modules are widely used in LAN (local area network) applications for data transmission and can be easily integrated into existing fiber optic networks.
LAN WDM module provided by OPTICO is based on TFF (thin film filter) wavelength division multiplexing technology, using a free space structure packaging method, its packaging size is greatly reduced compared with traditional passive modules, and the insertion loss is lower, It has better consistency and conforms to industrial standards. It is suitable for 40G&100G CFP optical modules and is widely used in data centers, cloud computing, metropolitan area networks and other fields.
