17dBm - 23dBm 2-stage C-band EDFA module with mid-stage port, 23dB gain version

17dBm - 23dBm 2-stage C-band EDFA module with mid-stage port, 23dB gain version. Alcatel 1926 OFA DWDM, Add Drop MUX, P/N:3CN 00423AA. With 9 fiber connectors.
 
Dual-stage basic unit can offer 17dBm output without external pump, it can also offer 20dBm (at 89mW or higher 1480nm external pump input ) or 23 dBm output (at 275mW or higher 1480nm external pump input, see test sheet).
 
23dB gain version. At the mid-stage port, it allows to insert 9-dB loss unit, such as DCM, OADM, DGFF, VOA.
 
With one SC/APC fiber connector for external pump input, 8 SC/PC connectors (see description at the pdf link below).
 
Description
The Alcatel 1926 OFA (Optical Fiber Amplifier) is designed to offer excellent Performance characteristics for WDM systems in the 1529.1 - 1561.8 nm wavelength range. The standard, double-stage 17 dBm unit can be supplemented using external pump modules to achieve outputs of 20 dBm or 23 dBm. A 9 dB mid-amplifier loss port has been designed in to allow for A/DMUX functions, dispersion compensation, etc. Tap couplers at each signal port offer full monitoring capability. The Alcatel 1926 OFA achieves very flat gain in excess of 23 dBm or 26 dBm, while limiting gain excursion to less than 1 dB (typical) over the entire 32.7 nm wavelength range. Optimization of the architecture yields very low typical noise figures less than 5 dB for the 17 & 20 dBm configurations.
