PCT No. PCT/GB94/00602 Sec. 371 Date Jan. 29, 1996 Sec. 102(e) Date Jan. 29, 1996 PCT Filed Mar. 23, 1994 PCT Pub. No. WO95/03653 PCT Pub. Date Feb. 2, 1995A method of compensating for dispersion in an optical communications system includes the steps of: positioning a semiconductor optical amplifier between a first and a second length of optical fibre, launching optical signals into the first length of optical fibre, directing optical signals emerging from the first length of optical fibre into the semiconductor optical amplifier, supplying optical pump radiation to the semiconductor optical amplifier so that the optidcal signals and the pump radiation interact within the semiconductor optical amplifier and generate the phase conjugate of the optical signals, and launching the phase conjugate optical signals into the second length of optical fibre.
