Optical amplifier arrangement |
摘要 |
<p>An optical amplifier arrangement for WDM systems (wavelength division multiplex) uses a common pump source (PSo) connected to an input of an splitter (SP) deploying pump light via variable optical attenuators (VOA1 - VOAn) to a plurality of optical amplifiers (A1 - An). Control circuits (C1 - Cn) determine individually the output powers of the amplifiers (A1 - An) by varying the attenuations of the variable optical attenuators (VOA1 - VOAn). Amplifier units based on PLC technology are implemented to reduce the size.</p> |
