“…It may be noted that the RIN of -110 dB/Hz is good enough to transmit 1.25-Gb/s nonreturn -to-zero (NRZ) data [11]. For demonstration of the broadcasting signal transmission by using the MI F-P LDs, we have the experimental set up as shown in Figure 5.…”

We demonstrate a cost effective broadcast signal transmission at 1.25-Gb/s with 100 GHz channel spacing based on a broadband light source (BLS) for a wavelength division multiplexing-passive optical network (WDM-PON). The BLS is implemented by using mutually injected Fabry-Perot laser diodes (MI F-P LDs). The error-free transmission without a forward error correction (FEC) is achieved by its low relative intensity noise (RIN). The number of usable modes is determined by RIN and/or extinction ratio (ER) in the spectrum sliced light output.

“…In addition to the use of intensity modulation and colorless transceivers, techniques of wavelength reuse in a loopback configuration [1][2][3][4][5][6][7][8][9] can play a significant role in the design of future high-capacity and cost-effective WDMPONs. This is because the sharing of a single wavelength for both data flows leads to more efficient optical spectra usage, allowing a higher number of available channels when compared to the scenario of distinct wavelengths for upstream and downstream.…”

“…Combining those techniques, RSOA-based intensityremodulation topologies by means of narrow-band amplified spontaneous emission (ASE) injection have already been widely demonstrated [1][2][3][4][5][6][7]. The intrinsic gain compression of RSOAs is jointly used with electronics carrier erasure techniques such as feed-forward current injection (FFCI) and decision threshold control (DTC) [1][2][3][4][5], as well as prespectrum slicing light (PSSL) injection [6,7], to relax the intensity-remodulation constrains.…”

“…However, the link lengths of conventional intensityremodulation approaches [1][2][3][4][5][6][7] are limited to 20 km, even with the support of FFCI, DTC, and PSSL methods. This is due to impairments related to the optical spectral content, arising from narrow-band ASE injection, such as the post-filtering effect (PFE), chromatic dispersion (CD), and ASE-ASE beat noise.…”

We experimentally investigate the impact of chromatic dispersion (CD), post-filtering effects (PFEs), and backreflection-induced penalties on intensityremodulation 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 as optical spectra and bit error rate (BER) performance up to 100 km, are measured and directly compared to a conventional prespectrum slicing light (PSSL) injection topology, in order to highlight the advantages and drawbacks of the self-seeding scheme. Downstream and bidirectional reaches up to 80 and 60 km, respectively, with a maximum 2 dB power penalty (for a BER of 10 −12 ) at 1.25 Gb/s operation are demonstrated in our self-seeding configuration, which enables enhanced resilience to CD and PFE effects while surpassing the conventional PSSL scheme in about 40 km.
