C- and O-Band Operation of RSOA WDM PON Self-Seeded Transmitters up to 10  Gb/s [Invited]

Abstract

We propose a network-embedded colorless self-tuning transmitter for wavelength division multiplexed (WDM) networks based on self-seeding in reflective semiconductor optical amplifiers (RSOAs). We compare up to a 10-Gb/s data rate in either O-band or C-band operation. In particular, the transmitter exploits a two-Faraday rotator configuration to ensure polarization-insensitive operation and allowing for the exploitation of high-gain C-and O-band RSOAs, which present a very high polarization-dependent gain. Two different multiplexers and various lengths of drop fibers constituted the networkembedded transmitters in order to evaluate various dispersion load influence on cavity buildup. Moreover, transmission over standard single-mode feeder fiber has been evaluated both at 2.5 and 10 Gb/s to compare the performance in both bands, confirming the absence of chromatic dispersion penalties for the O-band operation.

Self-Seeded RSOA-Fiber Cavity Lasers vs. ASE Spectrum-Sliced or Externally Seeded Transmitters—A Comparative Study

“…Lasing is obtained through the cavity, which extends from one highly reflective facet of the SOA up to another mirror behind a WGR filter. This way the RSOA source within the mirrors forms a long Fabry-Perot laser cavity [1,5,26,27]. The color dashed lines indicate the lasing cavities.…”

Flexible TWDM PON with WDM overlay for converged services

“…Another approach to increase the capacity of broadband optical access is to use pure WDM. WDM PON can provide dedicated wavelength at 1$10 Gb/s to each user [12][13][14]. However, most WDM PON systems require AWGs (arrayed waveguide gratings) as a wavelength multiplexer and demultiplexer, instead of optical splitters, in the outside fiber plant [12].…”

Colourless Self-Seeded Source for CPRI3 Mobile Fronthaul over 70 km Reach

“…Among dense WDM technologies suitable for the access, the use of self-seeded reflective semiconductor optical amplifiers (RSOAs) is particularly attractive since no wavelength control is required 2 . This technology already produced high performance laboratory experiments results with bit rates up to 10 Gbit/s and long reach transmissions 3,4 . In this work, we introduce a forward error correcting (FEC) Reed Solomon 240/218 code in a common public radio interface (CPRI) frame mapping of a new transponder in order to ensure error free transmission (i.e.…”
