The increase in broadband services supporting 4K/8K video is, Anritsu observes, one of the drivers for the expansion of optical access networks using Passive Optical Network (PON). This rapid growth in data traffic is driving the transition of these optical access networks to high-speed 10-Gbit/sec PON technology, while simultaneously needing to assess the adoption of the next-generation 100G-EPON standard (IEEE802.3ca) offering bit rates of 25 Gbit/sec per signal. As a result, the development of OLT and ONU units for PON systems requires both wideband 25-Gbit/sec performance as well as more precise timing and margin measurements due to the shorter time per bit.
The MP1800A is a plug-in modular Bit Error Rate Tester (BERT) for measuring a wide range of interfaces up to multichannel 64 Gbit/sec. The MP1800A signal-source multichannel synchronization and skew adjustment functions are optimum for OLT tests requiring high-accuracy timing setting. High-reproducibility BER measurement is achieved by high-quality output waveforms and high input sensitivity performance. The MX180014A software controls the MP1800A to generate 2ch test-signal burst patterns and set skew. OLT evaluation input sensitivity and timing tests are set up by the GUI for test-signal pattern length and timing.
