A wavelength-reuse topology with downstream carriers based on 1.25 Gb/s directly modulated self-seeded reflective semiconductor optical amplifier (RSOA) is investigated in regard to post-filtering effects (PFE) and chromatic dispersion (CD) tolerances. Downstream and bidirectional reaches up to 80 and 60 km, respectively, with maximum 2 dB power penalty (for a BER of 10−12) on 1.25 Gb/s are achieved...
We experimentally investigate the impact of chromatic dispersion (CD), post-filtering effects (PFEs), and backreflection-induced penalties on intensity-remodulation topologies based on self-seeded directly modulated reflective semiconductor optical amplifiers (RSOAs) acting as downstream carriers. Optical eye diagrams and power penalties as a function of link reach and reflection tolerances, as well...
We propose a RSOA-based WDM-PON architecture, combining self-seeding and carrier remodulation. A maximum 2.5 dB power penalty for a BER@10-10 was achieved for an injection power of - 22 dBm on 1.25 Gbps transmission.
In this work we propose a novel wavelength division multiplexing passive optical network (WDM-PON) configuration. The system is based on a colorless optical source employing the injection of amplified spontaneous emission (ASE) into a reflective SOA (R-SOA). In addition, optical detection at the ONTs is carried out by PIN based receivers, without decision threshold level adjustment (DTLA). We investigated...
This work describes the experimental demonstration of a 80 km-reach PON system, with a 1:128 split ratio, using a conventional Gigabit-Capable Passive Optical Network (GPON) equipment. The experiment was made possible by the use of bidirectional 1310/1490 nm semiconductor optical amplifiers (SOAs) as well as by a change on the medium access control (MAC) protocol. Results for packet-loss ratio and...
