Abstract
An optical communications system, comprising a first node, first dispersion compensation fiber located in the first node, wherein the first dispersion compensation fiber induces dispersion onto optical signals passing through the first dispersion compensation fiber, a second node, a plurality of spans between the first and second nodes, and second dispersion compensation fiber located in at least one of the spans, wherein the second dispersion compensation fiber induces dispersion onto optical signals passing through the second dispersion compensation fiber, and wherein the dispersion induced by the second dispersion compensation fiber is opposite in sign to that induced by the first dispersion compensation fiber.
Claims18
An optical communications system, comprising:
- a first node;
- a second node;
- a plurality of spans between the first and second nodes, wherein each of the spans include transmission media;
- at least one amplifier between the plurality of spans;
- a first dispersion compensation fiber located in the first node;
- a second dispersion compensation fiber located in the second node, wherein the second dispersion compensation fiber has a same sign as the first dispersion compensation fiber;
- and
- a third dispersion compensation fiber located in the at least one amplifier between the plurality of spans, and wherein the third dispersion compensation fiber induces dispersion that is opposite in sign to that induced by the first dispersion compensation fiber.
An optical communication system, comprising:
- a plurality of nodes;
- a plurality of links, each link connecting a plurality of nodes;
- a plurality of spans forming each link;
- a plurality of amplifiers between the spans;
- negative dispersion compensation fiber located in at least one of the nodes;
- positive dispersion compensation fiber located in at least one of the amplifiers and nodes.
A method of propagating an optical signal, comprising:
- introducing dispersion compensation into the optical signal in a first node;
- directing the optical signal into a link including at least one amplifier;
- dispersion compensating the optical signal a plurality of times in the amplifier in the link, such that dispersion compensation in the link is opposite the additional dispersion introduced in the first node;
- directing the optical signal into a second node;
- dispersion compensating the optical signal in the second node, such that the dispersion compensation in the second node is opposite in sign to dispersion compensation in the amplifier.
