摘要： A method and system for upgrading service to an optical network terminal among a plurality of optical network terminals on a passive optical network. The upgrade enables bidirectional communications between a central office and the optical network terminal over dedicated downstream and upstream wavelength channels outside the downstream and upstream wavelength bands associated with the passive optical network. The optical network terminal to receive upgraded service is disconnected from a passive optical splitter at a remote node serving the optical network terminal, and optically coupled to a port of the multi-port arrayed waveguide grating at the remote node. Wavelength taps are provided at the central office and the remote node to facilitate multiplexing and demultiplexing the dedicated downstream and upstream channels with the downstream and upstream wavelength bands associated with the passive optical network. In this manner, certain users on the passive optical network may receive service upgrades to wavelength specific services without affecting other users who remain on the passive optical network.

摘要： A multi-band hybrid amplifier is disclosed for use in optical fiber systems. The amplifier uses Raman laser pumps and semiconductor optical amplifiers in series to produce a relatively level gain across the frequency range of interest. Multiple Raman pumps are multiplexed before coupling into the fiber. The Raman amplified optical signal may be demultiplexed and separately amplified by the SOAs before re-multiplexing. Gain profiles of the Raman pumps and the SOAs are selected to compensate for gain tilt and to alleviate the power penalty due to cross-gain modulation in the SOAs. The disclosed hybrid amplifier is especially useful in coarse wavelength division multiplexing (CWDM) systems.

摘要： Several discrete hybrid amplifiers are used in parallel for amplifying an optical signal in an optical fiber system. An optical signal is first split into two or more separate signals each with a separate wavelength band. Each wavelength band is then amplified by a Raman pump utilizing a length of highly non-linear fiber as the gain medium, and by an SOA amplifier. The combination of the Raman amplifier and the SOA yields a level gain over the wavelength band. The amplified wavelength band signals are then recombined. The disclosed amplifier is especially useful in coarse wavelength division multiplexing (CWDM) systems and in local access portions of the network.
