The MP1800 series is made up of highly expendable, plug-in bit error rate testers (BERT) with a modular design and a test rate from 0.1 Gbit/s to 32.1 Gbit/s, or 56 Gbit/s with external MUX/DEMUX. The MP1800 series is also capable of jitter tolerance testing up to 32.1 Gbit/s, crosstalk testing and skew tolerance testing using the synchronized multichannel PPG, and comprehensive signal analysis including Burst measurement for PON and EDFA loop circuit testing. This signal quality analyzer supports signal integrity analysis for a variety of 100G+ applications including high speed backplanes and interconnects, high speed chips/devices, active optical cables, and optical transceiver modules.
