DISTRIBUTED AMPLIFICATION EDFL MULTIPLE WAVELENGTH LASER SOURCE

Title:

DISTRIBUTED AMPLIFICATION EDFL MULTIPLE WAVELENGTH LASER SOURCE

Document Type and Number:

WIPO Patent Application WO2001063818

Kind Code:

A8

Abstract:

Optical communication system apparatus (1100, 1200) and methods of operating an optical communications system are described, wherein a wavelength laser source (1360) is utilized to provide channel synchronization signals for the system (1000). The laser source (1360) utilizes a plurality of Erbium doped fiber lasers. The output of each laser is shaped with a fiber grating, amplified with an Erbium doped fiber amplifier, and multiplexed together.
