World's First TO-can Coherent Transceiver
2018 Optical Fiber Communications Conference and Exposition (OFC), 2018•ieeexplore.ieee.org
… Eg, the FSAN standardization group seeks for coherent 100G for its future optical access
system (FOAS). As a first step towards this goal this work experimentally demonstrates, to
the first time, an analogue coherent transceiver in transistor-outline (TO) package. Full-duplex
data rates up to 8 Gb/s are achieved over 27.5 km through DSP-less coherent homodyne
detection. Negligible reception penalties are found for simultaneous upstream transmission
using the same device as transmitter. …

We fit both, coherent homodyne receiver and transmitter, in a transistor-outline package with single fiber/RF port. Full-duplex 2.5Gb/s transmission over 27.5km reach, 28dB loss budget and coherent Ethernet connectivity are demonstrated without optical-layer DSP functions.
