Abstract
A method includes mapping, by an optical transceiver, a received first OTU4 signal to a first FlexO frame without interleaving the first OTU4 signal into an ODUC signal prior to mapping the first OTU4 signal to the first FlexO frame. The method also includes communicating, by the optical transceiver, the first FlexO frame with the mapped first OTU4 signal to a coherent DSP over a first FOIC.
Claims20
A method comprising:
- mapping, by an optical transceiver, a received first optical channel transport unit 4 (OTU4) signal to a first flexible optical transport network (FlexO) frame without interleaving the first OTU4 signal into an optical data unit-C (ODUC) signal prior to mapping the first OTU4 signal to the first FlexO frame;
- and
- communicating, by the optical transceiver, the first FlexO frame with the mapped first OTU4 signal to a coherent digital signal processor (coherent DSP) over a first FlexO electrical interface (FOIC).
An optical transceiver comprising:
- a first port configured to receive a first OTU4 signal;
- and
- a framer circuit configured to:
- map the first OTU4 signal to a first FlexO frame;
- and
- communicate the first FlexO frame with the mapped first OTU4 signal to a coherent DSP over a first FOIC.
