In the last mile of telecommunication network technology, optical transmission network has been deployed using the Fiber-to-the Home (FTTH) technology to provide broadband user demands. Evolution of the FTTH network change very rapidly, causing an implementation of existing and new technology should be in coexistence or called in hybrid mode. Optical distribution networks consist of more than 60% of the total investments in deploying Passive Optical Networks (PON). So, it is essential for the evolution of PON to cooperation with the existing networks. This paper discusses compatible hybrid application of the Gigabit Passive Optical Network (GPON) and the 10-Gigabit-capable Passive Optical Network (XGPON) for splitting ratio of 1:64. The performance of the hybrid network system is analyzed using The Opti-system software tool. The transmitter, the receiver and the transmission channel are set in compliance to the ITU-T standards series G.984. A laser component with NRZ modulation scheme and the transmitter power is adjusted to maximum power. The fiber optic cable uses the Single Mode Fiber (SMF) and the bit rate used in the GPON is 2.5 Gbps downstream and 1.25 Gbps upstream, while on the XGPON the bit rate are 10 Gbps downstream and 2.5 Gbps upstream. The result of experiment by simulation shows that the performance of hybrid GPON and XGPON technology for 1:64 splitting ratio is suitable to be implemented in FTTH to provide broadband services. It means that the migration from GPON to XGPON can be done smoothly via hybrid mode to keep safe existing investment of Telco operators.

“…An OLT at a central office is connected to multiple ONUs at the user premises via optical fiber through a passive optical splitter/combiner. Amplifications with/without multiple levels of splitting may be included to cope with a large number of ONUs or to extend the transmission distance in a long-reach option, as presented in [6,18,19].…”

To guarantee delay performances for timesensitive services in an orthogonal frequency-division multiple access passive optical network (OFDMA-PON), we propose a two-dimensional (i.e., subcarriers and time) upstream bandwidth allocation method based on interleaved polling with adaptive cycle time (IPACT). We first analyze its delay performance in terms of cycle time, i.e., the length of a polling cycle. Then, by setting the maximum polling cycle so as to guarantee timely transmissions for time-sensitive services, we identify the requirements, i.e., the maximum bandwidth allocation, the maximum number of allowed optical network units, and the optimum number of subcarriers, for upstream bandwidth allocation with delay guarantees. The proposed scheme is evaluated both numerically and via simulation.
