Terrestrial repeater and optimized repeater spacing
Disclosed are a system and a method for configuring an optical transmission system. A process may include arranging a first ruggedized repeater on or in a first object or structure. A second ruggedized repeater may be arranged on or in a second object or structure different from the first object or structure. A third ruggedized repeater may be arranged on or in a third object or structure different from the first and second objects or structures, wherein: (i) a first distance between the first ruggedized repeater and the second ruggedized repeater and (ii) a second distance between the second ruggedized repeater and the third ruggedized repeater are equal or nearly equal and based on signal loss.
1 . A method, comprising:
arranging a plurality of optical repeaters equally spaced along a portion of a bidirectional optical transmission path to transmit optical information signals, each optical repeater having at least a first and second optical amplifiers to accommodate signal amplification along the bidirectional transmission path in a first direction and a second direction opposite the first direction,
wherein each of the optical amplifiers are configured to have the same or nearly the same optical gain characteristics,
wherein the repeaters are equally spaced based on a predetermined value of signal loss associated with first and second optical amplifiers in each of the plurality of optical repeaters.
2 . The method of claim 1 wherein the plurality of repeaters are disposed on a corresponding plurality of utility poles.
3 . The method of claim 1 , wherein the plurality of repeaters are disposed in a corresponding plurality of manholes.
4 . The method of claim 1 , wherein a first portion of the plurality of repeaters are disposed on a corresponding number of utility poles and a second portion of the plurality of repeaters are disposed in a corresponding number of manholes.
5 . The method of claim 1 , wherein the first, second, and third optical repeaters are ruggedized repeaters.
6 . The method of claim 1 , wherein the each of the first and second optical amplifiers in each of the plurality of optical repeaters are single stage amplifiers.
7 . An optical transmission system, comprising:
an optical transmission cable;
