This paper reports performance tests on a DC-coupled 10Gb/s burst-mode receiver with on-chip reset, designed for 10G-GPONs. Record short 2R settling time, high sensitivity and large loud/soft ratio is demonstrated in burst-mode operations at 2.5G/5G/10Gb/s.

Abstract:We present for the first time a high performance APD-based linear burst-mode receiver (BM-RX) with a record wide dynamic range of 31dB. The APD multiplication factor is controlled from burst to burst within 60ns by an on-chip self-generated M-control signal. In the experiment, a total optical budget of 54dB is achieved with a single SOA-based reach extender for 10Gb/s upstream. With electronic dispersion compensation, the APD linear BM-RX with a wide dynamic range relaxes the requirement on optical components and lowers the system cost, especially at the optical network unit (ONU) side.

We demonstrate a 60-km CWDM-TDM PON with 40 Gb/s capacity both down and upstream. The system incorporates technologies such as volume manufacturable transmitters, burst-mode transmission, hybrid SOA-Raman amplifiers, and a cyclic CWDM multiplexer.
