A 10Gb/s APD-Based Linear Burst-Mode Receiver with 31dB Dynamic Range for Reach-Extended PON Systems

Abstract

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.

ASIC Implementation Challenges for Next Generation Access Networks

“…Low-noise operation is critical to support the required optical budgets. A first such LBMRx was demonstrated in [11]; another example can be found in [12] featuring an avalanche photodiode (APD) to improve sensitivity. Note that when considering advanced modulation formats for the upstream, some of these (e.g.…”

An Asymmetric High Serial Rate TDM-PON With Single Carrier 25 Gb/s Upstream and 50 Gb/s Downstream

“…Both blocks were designed and fabricated in a 0.13 μm SiGe BiCMOS process. The linear BM-TIA is based on the design in [14] but with a transimpedance gain adapted for the decoder IC and a fine-tuned bandwidth (one-fourth of the upstream data rate). The 1/4-rate small-signal bandwidth and linear operation are required for optimal three-level signal generation.…”

480Mbps/1 Gbps radio-over-fiber link based on a directly modulated III-V-on-Silicon DFB laser

“…The optical power at the photodiode was estimated to be -3 dBm due to the grating coupler losses. A linear TIA [7] was integrated with the silicon receiver PIC using wire bonding and connected to an Anritsu signal analyzer used to demodulate the signal and determine the error vector magnitude (EVM). A linearity measurement of the entire link is shown in Fig.…”
