Anritsu Corporation has announced that the company is exhibiting its Signal Quality Analyzer MP1800A series 64 Gbaud PAM4 BER test solution at ECOC 2016 from September 19 to 21, 2016 in Düsseldorf, Germany.
The exhibit will include the G0374A 64 Gbaud PAM4 DAC supporting 53.125-Gbaud PAM4 transmissions defined by the next-generation 400GbE standard as well as generation of high-quality PAM4 signals at up to 64 Gbaud. Additionally, 400GbE 53.125-Gbaud BER measurements are supported as a BER measurement set with high input sensitivity. Commercial sales of the G0374A 64 Gbaud PAM4 DAC start from October 2016.
The explosive increase in data traffic is driving investigation into communication speed increases between servers and network equipment. The next-generation 400GbE Ethernet standard uses the PAM modulation method to increase data transfers per unit time by increasing the symbol rate and adding more lanes. PAM4 signals have advantage over NRZ signalling in doubling the amount of transferred data per unit time, but suffering from the disadvantage of requiring solutions to technical issues such as lowering the power consumption and improving the S/N ratio; these tests require high-quality signal sources and high-input-sensitivity measurements.
Although Anritsu’s Signal Quality Analyzer MP1800A series supports evaluation of devices and optical modules meeting the latest communications standards, the MP1800A series Multichannel Pulse Pattern Generator (PPG) and Error Detector (ED) can be easily expanded using the G0374A 64 Gbaud PAM4 DAC and MP1862A 56G/64 Gbit/s DEMUX to support high-baud-rate the NRZ and PAM4 methods as well as BER measurements.
[Outline of PAM4 BER Test using G0374A and MP1800A Series]
The Signal Quality Analyzer MP1800A is a plug-in module type Bit Error Rate Tester (BERT) that can generate up to 8 channels of synchronized signals using the 32G Multichannel PPG module. The exhibited G0374A is an accessory part for the MP1800A series that is used in combination with the MU183020A 32 Gbit/s Multichannel PPG to generate 64-Gbaud NRZ/PAM4 signals by simple conversion of half-rate 32-Gbit/s NRZ signals. Additionally, combination with the MP1862A 56G/64 Gbit/s DEMUX and MU183040B 28G/32 Gbit/s High Sensitivity ED supports BER measurement of high-baud-rate PAM4 signals.
