“…6. It should be noted again that those components can be integrated by a compact R-SOA-EAM module [22]. Unfortunately, the used EAM in our demonstration has a large insertion loss of 17.5 dB under signal modulation.…”

We investigate reduction of mode partition noise of a spectrally sliced Fabry-Perot laser diode (FP-LD) for application to seeded DWDM systems. The proposed scheme for the noise reduction incorporates a fiber-based Mach-Zehnder interferometer (MZI) and a reflective semiconductor optical amplifier (RSOA). The MZI enables to reduce a relative intensity noise (RIN) more than 3 dB with better noise distributions. Experimental results of 10-Gb/s signal transmission exhibit a considerable bit-error-rate (BER) reduction by three orders of magnitude at the given received power. After the noise reduction, the FP-LD is applied to a 10-Gb/s DWDM system as a seed-light-source. In a local-seeding scheme, return-to-zero (RZ) and carrier-suppressed (CS)-RZ signal formats are compared as a function of transmission distance. Furthermore, a back-reflection induced impairment is evaluated in a remote-seeding scheme. We also count the number of useable channels to show the feasibility of DWDM transmission.

“…Based on this technology, the increase in bit-rate per channel to 10 Gb/s or over was considered difficult due to the beat noise of the spectrumsliced ASE light and limited modulation bandwidth of the reflective modulators such as an anti-reflection coated Fabry-Perot laser diode (F-P LD) or a reflective semiconductor optical amplifier (RSOA). Lately, however, an interest in an integrated high-speed reflective modulator is being raised [12,13]. Also, it has been known that the 10 Gb/s signal transmission in the ASE-seeded WDM-PON is feasible at 100 GHz channel spacing based on the use of a high-speed reflective modulator and a forward error correction (FEC) [7].…”

“…The output light of the RSOA was modulated with the EAM. Note that the RSOA, EAM, and two circulators can be replaced by an integrated reflective modulator such as an SOA-REAM for simple and cost-effective implementation [7,12]. We used these devices, since we do not have an SOA-REAM for 10 Gb/s operation.…”

We demonstrate and characterize 800 Gb/s capacity WDM-PON with an ASE injection seeding. Required total seed power at central office to feeder fiber is 16 dBm for 20 km upstream transmission of 80 channels. We investigate the maximum transmission length according to channels. The transmission length is limited to 39.7 km by intra-channel crosstalk induced by Rayleigh back-scattering, provided that the dispersion is compensated. Also, we investigate the allowable differential path length to evaluate the flexibility of the system.

“…Another issue for WDM-PON is the cost-effective, high operating performance colorless optical source in the optical network unit (ONU). The reflective semiconductor optical amplifier (RSOA) and the semiconductor optical amplifier-reflective electro-absorption modulator (SOA-REAM) are both used in loopback mode to transmit the uplink data [4]. Therefore, they obviously do not be applied to the wavelength-reuse system because of the wavelengths overlapping of upstream optical carrier and downstream signal in the downstream direction.…”
