Abstract:
An optical communications station, comprising:a fiber communications link carrying a fiber communications signal falling in a signal wavelength range; a fiber equipment rack having fiber equipment units for communicating with the fiber communications link, the fiber equipment units including a Raman pump unit generating Raman pump light in a pump light wavelength range; a fiber interface frame containing fiber interface devices for interfacing between the fiber communications link and the fiber equipment rack; and a coupling unit disposed between the fiber communications link and the fiber interface devices, the coupling unit permitting passage of light in the signal wavelength range between the fiber communications link and the fiber interface devices and the coupling unit coupling the Raman pump light from the Raman pump unit into the fiber communications link, whereby the fiber communications link provides Raman gain to the fiber communications signal.
