Abstract
Official abstract text for this publication.
Provided is an optical transmission system that includes: a transponder having a transmitter and a receiver; a loopback path that directly couples a signal of the transmitter to the receiver; and a server that calculates, based on a signal transmitted using the loopback path, a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter.
First claim
Opening claim text (preview).
1 - 7 . (canceled) 8 . An optical transmission system including a transponder having a transmitter and a receiver, the optical transmission system comprising: a first path configured to directly couple a signal of the transmitter to the receiver; and a calculation device configured to calculate, based on a signal transmitted using the first path, a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter. 9 . An optical transmission system comprising: first and second premises each comprising a transponder comprising a transmitter and a receiver; a first path connecting the transmitter of the transponder of the first premise to the receiver of the transponder of the second premise, the first path passing through an optical transmission path connecting between the first and second premises; and a second path not passing through the optical transmission path and connecting the transponder of the first premise and the transponder of the second premise to feed back bit error rate information from the second premise to the first premise, wherein the first premise further comprises a calculation device configured to calculate, based on the bit error rate information fed back through the second path, a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter of the transponder of the first premise. 10 . An optical transmission system comprising: a first premise comprising a transponder comprising a transmitter; a second premise comprising a reference transponder comprising a receiver; a path connecting the transmitter of the transponder of the first premise to the receiver of the reference transponder of the second premise, the path passing through an optical transmission path connecting between the first and second premises; and wherein the optical transmission system is configured to calculate a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter of the transponder of the first premise, based on a signal of the reference transponder. 11 . An optical transmission system comprising: a first premise comprising a transponder comprising a transmitter; a second premise comprising a spectrum analyzer; a path connecting the transmitter of the transponder of the first premise to the spectrum analyzer of the second premise, the path passing through an optical transmission path connecting between the first and second premises; wherein the optical transmission system is configured to calculate a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter of the transponder of the first premise, based on a result of a measurement by the spectrum analyzer. 12 . A method of designing an optical transmission system comprising: a transponder including a transmitter and a receiver; and a first path configured to directly couple a signal of the transmitter to the receiver, the method comprising calculating, based on a signal transmitted using the first path, a compensation value to compensate for frequency characteristics of a signal transmitted from the transmitter.
