As long-distance transmissions are always required in the CATV systems, it is very necessary to make the quality of visual and audio signals in high levels after the long transmissions, so that the performance of the CATV systems can be en…

Clearly different from the traditional repeater, the EDFA amplifier doesn’t need to convert the optical signals into electrical ones, then make the electrical amplification and finally convert the amplified electrical signals into amplifie…

To face the need for long-haul, high-capacity transmission, experts come up with several DWDM projects including DWDM Mux Demux, EDFA amplifier (erbium-doped fiber amplifier) and DCM module (dispersion compensation module) to expand networ…

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…
