Abstract
In this study, we use the injection-locked Fabry–Perot laser diodes (FP-LDs) with
front-facet reflectivities of 10% and 35% respectively, as colorless optical networking
unit (ONU) in long-reach passive optical networks (LR-PONs). Here, the injection-locked
FP-LD is directly modulated at 2.5 Gbit/s on-off keying (OOK) and 10 Gbit/s
orthogonal-frequency-division-multiplexing (OFDM) modulations for upstream traffic
transmission over 60 km of single-mode fiber (SMF). Different operating parameters for
the injection-locked FP-LD to achieve higher data rate transmission are
reported.
