Software Introduced by Anritsu Corporation Supports 100G/40G Band Optical Phase Modulation Schemes

- MP1800A Signal Quality Analyzer Evaluates DP-QPSK, DQPSK, DPSK, and ODB Optical Modulators and Transponders -

Anritsu Corporation has extended the 100Gbps test capabilities of its industry leading MP1800A Signal Quality Analyzer with the introduction of pre-code/decode software that has been developed to support the latest optical phase modulation schemes, including DP-QPSK, DQPSK, DPSK, and ODB, used in Next Generation Networks (NGNs). The new software package complements the 2-channel MUX/DEMUX configuration of the MP1800A to provide device manufacturers with a flexible, highly accurate test solution for evaluating high-speed optical modulators and transponders.

The pre-code and decode functions of the MX180000A-001/002 option help reduce 100G and 40G core-network R&D costs as well as time to market by supporting fully automatic generation of modulation signals needed to evaluate 100G DP-QPSK, and 40G DQPSK, DPSK, and ODB optical modulation technologies. The pre-code function automatically generates 100G DP-QPSK, and 40G DQPSK, DPSK, and ODB modulation signals for evaluating optical modulators. The decode function is for evaluating the logic of precoders in optical modules.

All electrical, modulation, and demodulation signals required for evaluating DP-QPSK, DQPSK, DPSK and ODB devices are generated automatically by the MP1800A. The test solution provides a number of benefits, including eliminating modulation pattern editing and programming, and reducing the time necessary for evaluating modulation errors and error rates.

Hardware-based generation of modulation signals produces pure PRBS31 signals without pattern length restrictions, so the MP1800A can conduct highly reliable evaluations using high-load pseudo random patterns that closely emulate live traffic. Users can vary the skew between I and Q signals with high resolution over a wide range (±64 UI, 2 mUI steps) to confirm the input skew margin of DQPSK modulators with confidence.

About the MP1800A
The MP1800A is the leading test instrument for 100Gbps applications. It produces an extremely high quality waveform and has a high-performance receiver with a wide phase margin of >288 degrees and typical input sensitivity of 50 MVp-p.

Providing a Pulse Pattern Generator (PPG) and Error Detector (ED) in a single chassis, the MP1800A allows for multi-channel support for parallel testing. It is ideal for research and development of 100/40G optical modulators, high-speed logic ICs, digital systems, and PON devices. It supports optical devices from 0.1 to 100 Gbits, the widest range available in its category.
