OPTICAL COMMUNICATIONS NETWORK |
摘要 |
An optical communications network in which optical signals from a transmitter (T) are distributed to receivers (Ri) via an optical waveguide (2) and couplers (Ci) are amplified as they propagate along the waveguide (2). The amplifiers Ai are all pumped by a single optical pump source (4) coupled to the optical fibre (2) by a dichroic coupler (6). By using the optical waveguide (2) to distribute the pump power to the amplifiers Ai multiple optical pump sources are avoided.
