Abstract:We present a comparative study of the capacity increase brought by bit-and power-loading discrete multi-tone (DMT) modulation for low-cost colorless transmitters. Three interesting reflective semiconductor optical amplifier (RSOA) based colorless transmitter configurations are compared: First, an amplified spontaneous emission (ASE) spectrum-sliced source; second, a self-seeded RSOA fiber cavity laser (FCL) and third, an externally seeded RSOA. With bit-and power-loaded DMT, we report record high line rates of 6.25, 20.1 and 30.7 Gbit/s and line rates of 4.17, 10.1 and 24.5 Gbit/s in a back-to-back and in a 25 km nonzero dispersion shifted fiber (NZDSF) transmission experiments for the three transmitter configurations, respectively. In all the experiments, BER (bit error ratios) below an FEC (forward error correction) limit of 7.5 × 10 −3 were achieved.

“…The need for a NZDSF to achieve longer reach may challenge the cost-efficiency of the RSOA. However, such dispersion management can either be obtained by deploying NZDSF or by deploying O-band RSOAs [41,42]. In central offices, electronic chromatic dispersion could also be an option.…”

Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs) are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks (WDM-PONs) based links. In this paper, we compare RSOA-FCLs with alternative colorless sources, namely the amplified spontaneous emission (ASE) spectrum-sliced and the externally seeded RSOAs. We compare the differences in output power, signal-to-noise ratio (SNR), relative intensity noise (RIN), frequency response and transmission characteristics of these three OPEN ACCESSAppl. Sci. 2015Sci. , 5 1923 sources. It is shown that an RSOA-FCL offers a higher output power over an ASE spectrum-sliced source with SNR, RIN and frequency response characteristics halfway between an ASE spectrum-sliced and a more expensive externally seeded RSOA. The results show that the RSOA-FCL is a cost-efficient WDM-PON upstream source, borrowing simplicity and cost-efficiency from ASE spectrum slicing with characteristics that are, in many instances, good enough to perform short-haul transmission. To substantiate our statement and to quantitatively compare the potential of the three schemes, we perform data transmission experiments at 5 and 10 Gbit/s.

“…A key advantage is that they provide passive tuning of the wavelength. This simply results from the selection of a given port of the wavelength multiplexer, which can be several kilometers away from the RSOA [1][2][3][4][5]. This contrasts with the use of singlemode semiconductor lasers, which need to be designed for a pre-set emission frequency and require active tuning and frequency control.…”

Abstract-Self-seeded cavity lasers appear as attractive colorless sources for dense wavelength division multiplexed passive optical networks. Although this technology has already demonstrated high performance in a number of experiments, the strong multimode behavior of these kilometer-long cavities results in large relative intensity noise (RIN) that can become the main limiting factor for transmission. In this letter, we correlate the transmission performance degradation to the RIN increase when the cavity length increases. We evidence a better tolerance to amplitude noise when a combination of Manchester encoding and balanced detection are used in a proof-of-concept experiment. Using this combination, the cavity length can be four times longer than when using standard non-return-to-zero encoding for the same bit-error-rate performance.Index Terms-Reflective semiconductor optical amplifier, colorless source, DWDM Passive optical network, RIN.
