Abstract
A method and apparatus for performing path protection for rate-adaptive optics is provided. As part of the method, an aggregate input bit stream is received. The aggregate input bit stream is then transmitted using a rate-adaptive optical transceiver when transmitting on a first optical path. When the first optical path has a fault, the aggregate input bit stream is then transmitted on a second optical path using the rate-adaptive optical transceiver and a fixed-rate optical transceiver.
Claims21
An apparatus, comprising:
- a rate-adaptive optical transceiver having a first receivable bit rate and at least a second receivable bit rate;
- at least one fixed-rate optical transceiver having a third receivable bit rate;
- and
- a means of receiving an aggregate bit stream from a first optical path and from at least a second optical path,
- wherein when receiving the aggregate bit stream from the first optical path, the rate-adaptive optical transceiver receiving with the first receivable bit rate is used, and wherein when receiving the aggregate bit stream from the at least a second optical path, the rate-adaptive optical transceiver receiving with the at least a second receivable bit rate and the at least one fixed-rate optical transceiver are used.

An apparatus, comprising:
- a group of one or more input ports having an aggregate input bit stream;
- a rate-adaptive optical transceiver transmitting using a first wavelength and a second wavelength;
- at least one fixed-rate optical transceiver transmitting using a third wavelength;
- and
- a means of transmitting the aggregate input bit stream on a first optical path and on at least a second optical path,
- wherein when transmitting the aggregate input bit stream on the first optical path, the aggregate input bit stream is transmitted by the rate-adaptive optical transceiver using the first wavelength, and wherein when transmitting the aggregate input bit stream on the second optical path, the aggregate input bit stream is transmitted by the rate-adaptive optical transceiver using the second wavelength and by the at least one fixed-rate optical transceiver.
3 more elements
A method for performing path protection, comprising:
- receiving an aggregate input bit stream comprising of a first portion and a second portion;
- transmitting the first portion and the second portion using a first optical transceiver when transmitting on a first optical path;
- and
- transmitting the first portion on a second optical path using the first optical transceiver following a fault on the first optical path, and transmitting the second portion on a third optical path using a second optical transceiver following the fault on the first optical path,
- wherein when transmitting the first portion and the second portion on the first optical path, the first optical transceiver transmits using a first transmittable bit rate, and wherein when transmitting the first portion and not the second portion on the second optical path, the first optical transceiver transmits using a second transmittable bit rate, wherein the first transmittable bit rate is greater than the second transmittable bit rate.
