The ‘commoditisation’ (i.e. using commodity hardware or commodity device as a hardware platform for network equipment) and ‘softwarisation’ (i.e. implementing the network function of the target equipment by software) have recently become big trends among communication carriers struggling to balance cost‐efficiency and service flexibility. Especially in optical access networks, the concept of the commodity layer 2 (L2) switch‐based passive optical network (PON) is attracting attention, but performance demonstrations have not been reported. This Letter offers the first performance demonstration of the L2 switch‐based gigabit ethernet PON prototype constructed with an L2 switch and software‐based PON‐specific functions. The prototype achieves nearly 1 Gbps throughput in one‐way transmission. Moreover, an additional numerical analysis confirms that the authors proposed architecture can accommodate sufficient PON port number.
