In this paper, we propose a new method for broadcasting in a WDM-PON system which has the merits of a simple and cost effective structure. It can be constructed using only an ASE (Amplified Spontaneous Emission) light source and a PI-RSOA (Polarization Independent -Reflective Semiconductor Optical Amplifier). Error-free broadcast signal transmission over 30 Km for 24 channels at 1.25 Gb/s has been successfully demonstrated.

“…However, even though virtual point-to-point connections with such optical sources can be made cost-effectively, it is inherently difficult to provide a multicasting (or broadcasting) function. Thus, optical sources for multicasting [4][5][6] or several multicasting overlay schemes [7,8] have been actively studied. In [4], a spectrum sliced amplified spontaneous emission (ASE) source has been proposed for multicasting but it requires an expensive external modulator and shows limited performance.…”

External Optical Modulator Using a Low-cost Fabry-Perot LD for Multicasting in a WDM-PON

An external optical modulation using absorption nulls in a Fabry-Perot laser diode (FP-LD), has been proposed and experimentally demonstrated for multicasting in a WDM-PON. The center wavelengths of absorption nulls in an FP-LD move to short-wavelength rapidly by only a small current (~1 mA) injection. If the current injection is stopped, the nulls move back to the original position. Such a movement of the nulls can make the FP-LD act as an external optical modulator, which is found to modulate at a maximum modulation speed of 800 Mbps or more. For a multicasting transmitter in a WDM-PON, the proposed modulator can be cost-effectively applied to a multi-wavelength laser source with the same periodicity of the longitudinal mode. Instead of the multi-wavelength laser source, tunable-LDs are used for experiments. The 32 channel multicasting system with the proposed modulator has been demonstrated, showing power penalties of 1.53~4.15 dB at a bit error rate of 10 -9 with extinction ratios better than 14.5 dB at 622 Mbps.

“…It has highly efficient use of the outside fiber by providing point-to-point connection to multiple remote optical network units (ONU) through just a single feeder fiber. Furthermore, for each connection, it has many advantages such as large bandwidths, bit rate independency, protocol transparency, easy upgradeability and excellent security [1][2][3][4][5][6][7][8][9][10].…”

A novel WDM-PON system delivering bidirectional 1.25-Gbps data and broadcasting data is proposed. A subcarrier signal modulates optical carriers of a Fabry-Perot-laser-diode based broadband light source to broadcast to all users. Reflective semiconductor optical amplifiers are used as modulators for the baseband data at both the optical line terminal and the remote optical network unit for a channel. Bit error rate and error vector magnitude were measured to demonstrate the proposed scheme.
