Coherent Optical Transceivers Scaling and
Integration Challenges
The advancement of
digital coherent technologies has dramatically increased the system
capacity per single-core single-mode fiber to the point that we can
now approach the Shannon limit by utilizing high-order modulation
formats and high-coding gain forward error correction (FEC) codes.
Because the required energy per bit increases exponentially the
closer we get to the Shannon limit, extending the available optical
bandwidth by using ultrawideband wavelength-division multiplexing (WDM)
and/or spatial-division multiplexing (SDM) is indispensable for
increasing the system capacity with high energy efficiency. However,
simple extensions of wavelength resources and spatial
parallelization dramatically increase the number of transceivers (TxRxs)
in proportion to the wavelength/spatial multiplicity. The key to
achieving cost- and energy-efficient systems is to reduce the system
complexity by using high-density integration and broadband
optelectronics. In this article, the recent advances of coherent
optical transceivers integrated with an optical front end and
digital signal processing (DSP)/application-specific integrated
circuit (ASIC) are overviewed and discussed. Then the transponder
architectures and the challenges involved in applying them for
massive parallelized transmission systems are presented. Read more
