The Transmitter and Dispersion Eye Closure (TDEC) is a metric originally introduced by IEEE 802.3 for short reach optical transmission in datacenters and later adopted for 50G-PON in ITU-T Recommendation G.9804.3. TDEC evaluates the performance of a transmission system as a penalty due to eye-diagram closure, comparing it to a reference ideal transmitter. To this end, the standard defines a procedure to be followed involving filtering, equalization and the definition of time windows inside the eye diagram. The purpose of this article is to show the correlation between TDEC and the Optical Modulation Amplitude receiver sensitivity in 50G-PON scenario using optical amplifiers either as booster at transmitter side (for the downstream direction) or as pre-amplifiers at receiver (in the upstream direction).
