Optical Amplifier is a Key Technology for Restoring Signals

With wavelength-division multiplexing (WDM) technology, which enables the transmission of multiple channels over the same fibre, optical amplifiers—the essential technology for optical communication networks—have enabled the transmission of numerous terabits of data over distances ranging from a few hundred kilometres to transoceanic distances. Fibre losses inevitably restrict the transmission…

Whether to Use EDFA Amplifier in Long WDM System Or Not?

Whether to Use EDFA Amplifier in Long WDM System Or Not?

Currently, utilizing WDM technology to deploy the optical network has received widespread attentions, which enables higher capacity for data transmission. However, the technology is also limited by the transmission distance. When deploying a long WDM system, the signal power would still become weak due to the fiber loss. In order to address the issue, using EDFA amplifier to directly enhance the…
