Less than 0.19-dB Transient Gain Excursion AGC-EDFA with Digital Control for 20-Channel Add/Drop Equivalent Operation
Transient Gain Excursion AGC-EDFA Digital Control 20-Channel Add/Drop
2015/5/20
We have developed a digitally controlled AGC-EDFA by combining an FF-controlled pump-LD and an FB-controlled VOA. An FPGA is used to finely tune the gain setting of the pump current with a wide dynami...
10.3Gb/s burst-mode 3R receiver incorporating full AGC optical receiver and 82.5GS/s sampling CDR for 10G-EPON systems
receiver incorporating AGC optical receiver CDR 10G-EPON systems
2015/7/16
10.3Gb/s burst-mode 3R receiver incorporating full AGC optical receiver and 82.5GS/s sampling CDR for 10G-EPON is, for the first time, developed. Burst receiver sensitivity of -30.1dBm and upstream po...
First Demonstration of Fast Automatic-Gain-Control (AGC) PDFA for Amplifying Burst-Mode PON Upstream Signal
Automatic-Gain-Control (AGC) PDFA Amplifying PON Upstream Signal
2015/8/3
The effectiveness of installing fast AGC in a PDFA for amplifying burst mode PON upstream signals is reported for the first time. The technique has the potential to realize high-gain/high-power burst-...
