Anritsu Introduces 48 Gbit/s Multiplexer and Demultiplexer for Evaluating 40G, FEC and Super FEC Devices, Modules and Systems

8/29/2002 - Anritsu introduces the MP1811A 48 Gbit/s multiplexer (MUX) and MP1812A 48 Gbit/s demultiplexer (DEMUX) that provide low jitter, low distortion output and Q-value measurement capability, respectively. The MUX and DEMUX can be controlled from an external PC via GPIB, allowing them to be easily integrated into bit error rate test (BERT) systems used to evaluate devices, modules and transmission equipment for next-generation optical networks such as 40G, FEC, and Super FEC.

Anritsu has designed the MP1811A MUX with a unique D flip-flop retiming output circuit that allows the MP1811A to achieve extremely high quality output waveforms. It is capable of multiplexing several low-bit rate signals into one signal with a higher bit rate. When used in combination with Anritsu’s MP1758A or MP1775A 12.5Gbit/s 4-channel pulse pattern generator and 69xxxB series signal generator, the MP1811A can perform 4:1 multiplexing of a low bit rate signal into a 25 Gbit/s ~ 48 Gbit/s signal.

Featuring a threshold resolution of 0.001V, the MP1812A supports Q-value measurement by setting the threshold voltage value of the high accuracy input decision circuit. It has a high-resolution variable delay capability that enables the error rate change of phase direction to be measured, and thus provides a "Bathtub Curve" with high accuracy. The DEMUX can also conduct highly accurate evaluations of an optical circuit’s quality and O/E devices used in optical circuits. It can be integrated with the MP1776A error rate detector to measure the error rate in signals from 25 Gbit/s ~ 48 Gbit/s.

The MP1811A and MP1812A are integral elements of Anritsu’s ME7780A BERT system. Delivering low phase noise and high sensitivity up to 48 Gbit/s, the ME7780A can perform highly accurate evaluations of 40G, FEC and Super FEC components, modules, and transmission systems.

Pricing starts at $304,500 for the MP1803A and $304,500 for the MP1804A. Delivery is 10 to 12 weeks.
