Abstract
In this paper, first burst-mode transmitter for 2.5-Gb/s gigabit-capable
passive optical networks (GPON) system is evaluated. Small form factor
(SFF) type optical network unit (ONU) generates 2.5-Gb/s optical eyes
with commercial distributed feedback-laser diode (DFB-LD). For the fast
burst signal access, burst enable (BEN) connection on the evaluation
board utilizes DC-coupling configuration. Resultant optical output
waveform shows 16.30 dB extinction ratio with wide eye opening for GPON
mask test. No significant eye degradation is detected in high
temperature operation and after 10 km distance transmission. Proposed GPON ONU successfully shows fast timing characteristics of 2.17 nsec for Tx enable stage and 1.17 ns for Tx disable stage.
