By using a pumped erbium doped fibre (EDP) cascaded with a non-saturable absorbing fibre (NSAF), an amplifier is provided with a desired flat uniform output response for a input signals with different at a plurality of wavelengths. Furthermore, from a commercial standpoint, the amplifier is relatively inexpensive and simple to fabricate, being compatible with standard telecommunication fibre. With this particular invention, a previously recognized undesired characteristic of NSAF, its poor amplification qualities, are now being used to an advantage.
