Optical Fiber Amplifiers and Their Applications. Optical Cable Amplifier.
The Review of Laser Engineering, 1997 An erbium-doped fiber amplifier installed inside an optical fiber cable is reported. This optical cable amplifier is mechanically flexible as the result of using a flexible stainless steel tube and wire mesh as the amplifier cavity and outer cover, respectively. The amplifier is pumped with a 0.98μm laser diode to reduce both the electric driving power
