An optical fiber connector is used as a means of carrying an optical element. The optical element is either permanently or removeably affixed to a planar end of the optical fiber connector with a suitable adhesive or gel. After the mating connector plugs are secured together, the affixed optical element is adjacent each end of each connector plug becoming in-line with the connector.

By using a pumped erbium doped fibre (EDF) 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 intensities 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.
