Title: Doped fibre optical amplifier for 1600 nm band
Inventor: DESTHIEUX BERTRAND
IPC: H01S3/16
Filed: 2000-02-17
Abstract: The invention concerns a doped fibre optical amplifier for L-band (band ranging from about 1570 to 1610 nm) comprising a doped optical fibre (10) including a doped monomode core (16) and a sheath (18, 20), and optical pumping means (12) optically coupled with the doped fibre. The invention is characterised in that said sheath comprises an inner multimode sheath (18) and an outer sheath (20), the pumping signal being injected into the inner sheath (18), and the monomode core (16) is doped so as to induce a mean energy population inversion less than 50 % in the doped fibre, and preferably ranging between 35 % and 45 %. The invention is applicable to wavelength division multiplexing optical transmission systems.
Patent CA-2330703-A1 (CA)
Inventor: MESECHER DAVID K
IPC: H04B1/7115
Filed: 1999-01-27
Abstract: A digital spread spectrum communication system employing pilot-aided coherent multipath demodulation effects a substantial reduction in global-pilot and assigned-pilot overheads. The system and method uses a QPSK-modulated data signal whereby the modulated data is removed and the recovered carrier is used for channel amplitude and phase estimation. The resulting signal (119) has no data modulation and is used as a pseudo-pilot signal (119). In conjunction with the pseudo-pilot signal, a multiple-input phase-locked loop (157) is employed further eliminating errors due to carrier-offset by using a plurality of pseudo-pilot signals. A pilot signal (135) is required to resolve absolute phase ambiguity, but at a greatly reduced magnitude.
