Combo-PON OLT Transceiver Using Photonic Integration Technology

In this work, a prototype of 10G Combo-PON OLT transceiver based on photonic integrated circuits (PIC) is proposed and demonstrated. Key optical components for Combo-PON OLT transceiver, including high-power DFB laser, micro-ring modulator and WDM, have been developed and validated. The Combo-PON OLT transceiver integrated four XGS-PON/GPON ports and all ports comply with I-TUT G.984.2 Class C+ standard. The advantages and disadvantages of PIC in PON application are analyzed. The analysis shows that PIC can also provide a cost and power-efficient way to implement the next generation PON transceiver for high density PON ports.
