This letter presents a low-power transimpedance amplifier (TIA), supporting both 25 and 40-Gb/s communication. It exhibits an optical modulation amplitude sensitivity of −10.6 dBm at 25 Gb/s and −6.4 dBm at 40 Gb/s using a photodiode with a responsivity of 0.55 A/W. The TIA consumes 158 mW from a 2.5 V supply and was manufactured in a 0.13-µm SiGe BiCMOS process. Compared with the state of the art, the presented TIA exhibits a similar sensitivity (at both 25 and 40 Gb/s), while exhibiting a low power consumption for the 40-Gb/s operation.

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 report the first 25Gb/s 3-level modulated BM-RX employing a ¼-rate linear BM APD-TIA and a custom decoder IC. We successfully demonstrated burst-mode sensitivity of -20.4dBm with 18dB dynamic burst-to-burst for 25Gb/s upstream links.OCIS codes: (060.2360) Fiber optics links and subsystems; (060.0060) Fiber optics and optical communication.

This paper presents a high performance DC-coupled 10 Gbit/s APD-based optical burst-mode receiver (BM-RX) for symmetric 10G-GPONs. The BM-RX can handle upstream bursts with a loud/soft range wider than 24.0 dB, and the measured sensitivity is −30.0 dBm at BER = 10 −3 after a start of burst settling time no longer than 51 ns. This paper also investigates, for the first time, the inter-burst guard time required for a 10 Gbit/s BM-RX with auto-reset generation, while the PON operates upstream at a high raw BER and is using FEC. ©2011 Optical Society of AmericaOCIS codes: (060.2360) Fiber optics links and subsystems; (060.0060) Fiber optics and optical communications.
