Title: Receiver Design Drives Optical Transmitter Test in the PAM4 Era

Event Type: DesignCon - Technical Session

Pass Type: All-Access Pass, 2-Day Pass

Theme: Internet of Things (IoT)


Description

When PAM4 was selected for use in optical communications systems it led to an overhaul in the methods used to specify and test transmitters, with TDECQ being the primary metric to assess contribution to a link budget.  The TDECQ method is highly dependent on the architecture of the receiver that the transmitter will be paired with.  Several years have passed since the institution of the PAM4 -based transmitter measurements.  Receivers continue to improve, but little has changed for transmitter test.  This paper will examine recent trends in next generation communications systems and what changes in transmitter test can be considered for improved specifications.
