Abstract
A sub-carrier multiplexing (SCM) system include a digital layer including circuitry configured to interface with a client via a client signal and to interface with a media layer via a plurality of constituent signals, that together comprise the client signal; and the media layer including sub-carrier multiplexing (SCM) with each sub-carrier configured to carry one of the plurality of constituent signals. The client signal can be an Ethernet signal, Optical Transport Network (OTN) signal, etc., and the plurality of constituent signals can be Flexible Ethernet (FlexE) layer signals, Flexible OTN (FlexO) layer signals, Metro Transport Network (MTN) layer signals, ZR layer signals, etc.
Claims20
A transmit circuit configured to:
- receive a client signal,
- process the client signal to form a plurality of constituent signals where the plurality of constituent signals comprise the client signal, and
- provide each of the plurality of constituent signals to a media layer for each of the plurality of constituent signals to be modulated on a respective sub-carrier in sub-carrier multiplexing (SCM).
A receive circuit configured to:
- receive a plurality of constituent signals from a media layer where each of the plurality of constituent signals are demodulated from a respective sub-carrier in sub-carrier multiplexing (SCM),
- process the plurality of constituent signals, which were aggregated together in the media layer, to form a client signal, and
- provide the client signal.
A sub-carrier multiplexing (SCM) system comprising:
- a digital layer including circuitry configured to interface with a client and to interface with a media layer via a plurality of constituent signals, that together comprise the client signal;
- and
- the media layer including sub-carrier multiplexing (SCM) with each sub-carrier configured to carry one of the plurality of constituent signals.
