An optical amplifier assembly comprises a Customer Interface module and a plurality of other amplifier modules. The Customer Interface module includes: (i) a customer interface configured to interact with other devices and (ii) optical and electrical connectors, connecting at least one of the other optical amplifier modules to the customer interface. According to one embodiment of the present invention the Customer Interface module

Customer interface module

According to one embodiment of the present invention an amplification module comprises a housing containing a plurality of optical ports. This housing: (i) at least partially encloses at least one amplification medium, (ii) provides at least one position for at least one optical filter, and (iii) includes a first optical port configured to provide both signal and pump light to the amplification module. According to an embodiment of the present invention the amplification module does not include a WDM for multiplexing pump light and signal light.

Optical amplification module

The optical amplifier includes a first gain medium having an optical host that contains a rare earth dopant and a first pump that supplies optical energy at a first wavelength into this first gain medium. The first pump operates at a pump wavelength that has a lower inversion saturation than the highest wavelength of absorption of the first gain medium. The optical amplifier further comprises a second gain medium operatively coupled to the first gain medium and a second pump that supplies optical energy into the second gain medium.
