1. A system comprising:
multiple light sources configured to generate multiple channels of light;
a multiplexer comprising a spatial mode coupler configured to convert light in the multiple channels of light into multiple higher-order spatial modes and to combine the multiple higher-order spatial modes on an optical fiber as multiple respective mode channels;
the optical fiber, configured to transmit the multiple channels of light to a sourceless co-packaged optical transceiver; and
the sourceless co-packaged optical transceiver, comprising multiple co-packaged optical transceiver modules and a demultiplexer comprising a spatial mode decoupler configured to separate the multiple mode channels based on the respective higher-order spatial modes and to convert light in the multiple mode channels into lower-order spatial modes to be input to the multiple co-packaged optical transceiver modules,
wherein the multiple co-packaged optical transceiver modules are configured to modulate the multiple channels of light and to transmit the multiple modulated channels of light to different respective destinations, and
wherein a first one of the co-packaged optical transceiver modules utilizes a first modulation format and a second one of the co-packaged optical transceiver modules utilizes a second modulation format that is different from the first modulation format.
