Discrete multitone toward 40 G-PON using 10 Gbps EML and APD

We investigate 40G-PON by using discrete multitone and 10-Gbps optical components with intensity-modulation and direct-detection. We demonstrate 40-Gbps transmission, with 23-dB power budget at 4.6 × 10-3 BER, after 10-km SSMF transmission.
