Network and Conversation Networks and interaction require connecting various systems and products to share data and information.
The fourth era of fiber-optic interaction systems used optical amplification to reduce the have to have for repeaters and wavelength-division multiplexing (WDM) to enhance details capability. The introduction of WDM was the beginning of optical networking, as WDM became the technologies of choice for fiber-optic bandwidth expansion.[24] The first to marketplace with a dense WDM program was Ciena Corp.
