First Claim
Patent Images
1. An apparatus, comprising:
- a group of one or more input ports having an aggregate input bit stream;
a rate-adaptive optical transceiver having a first transmittable bit rate and at least a second transmittable bit rate;
at least one fixed-rate optical transceiver having a third transmittable bit rate; and
a means of transmitting the aggregate input bit stream from the apparatus 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 rate-adaptive optical transceiver is used, and wherein when transmitting the aggregate input bit stream on the at least second optical path, the rate-adaptive optical transceiver and the at least one fixed-rate optical transceiver are used.

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.
