a. The wavelength range over which the small signal gain (at -20 dBm input power) does not fall below
35 dB.
b. Specified at 1550 nm. Please refer to published data on the Thorlabs website for typical curves showing
the variation of each parameter with wavelength.
c. Please refer to published data on the Thorlabs website for the scaling of the output power vs. the input
power.
d. After a 15 minute warm-up time, for ambient temperature fluctuations ±2 °C.
e. Amplifier dispersion can be minimized using a dispersion-compensating fiber patch cable. Patch cables
with custom dispersion compensation are possible by contacting
