Estimating the term…
A lossless optical link in an optical transmission system comprises an optical fiber that is configured to produce Raman gain and provide for Raman distributed gain, via one or more pump sources, along the fiber so that, as an end result, the gain experienced by one or more propagating signals in the fiber link is made fairly uniform along the link or at least a portion of the optical link, such as not vary, for example, no more than five dB along the length of the optical fiber. The several embodiments disclosed provide for different optical pump/component architectures to achieve this end result.
An optical fiber link comprising:
An optical fiber link comprising:
An optical fiber link comprising:
An optical fiber link comprising:
An optical fiber link comprising a plurality of signal sources, a plurality of pumps sources capable of exciting Raman gain in the optical fiber link, wherein at least one pump source is adjusted to selectively increase or decrease pump power.
A optical fiber link comprising:
A optical fiber link comprising:
A lossless fiber link in an optical transmission system, the link comprising an optical fiber with optical transmission characteristics that produce Raman gain in the fiber such that power of an optical signal or signals at a signal wavelength or bandwidth propagating through the optical fiber from the first end to the second end varies by no more than about five dB along a length of the optical fiber of about thirty kilometers or more due to Raman distributed gain provided by a pump source coupled to the fiber.
