摘要

We demonstrate sensitivities below -28.6dBm using an SOA-PIN receiver for the 50G-PON upstream. The effect of the optical filter bandwidth to reduce the SOA ASE is investigated to consider both uncooled and cooled ONU transmitters. Using an EML for the ONU transmitter, optical link budgets over 36dB are attained for the two upstream wavelength bands using the same SOA.
