Anritsu Company Introduces First 40G Jitter Measurement Solution Conforming To ITU-T O.172

Supporting Five Most Popular Jitter Measurements, MP1797A Accurately Measures Intrinsic Jitter of OC-768/STM-256 Devices and Transmission Systems

Richardson, TX — Anritsu Company introduces the MP1797A jitter analyzer, the first and only 40G jitter analysis solution that conducts measurements on 40G transmission devices and systems in accordance to ITU-T Standard O.172. The MP1797A can perform the five most common jitter measurements - jitter generation, jitter tolerance, jitter sweep, jitter transfer, and frequency sweep - with a high degree of accuracy due to customized jitter software, a built-in jitter generator and jitter receiver, and high performance O/E and E/O modules.

The high performance measurement capability of the MP1797A makes it a unique and essential tool for engineers who must measure intrinsic jitter while evaluating the performance of OC-768 and STM-256 devices during development and manufacturing. The MP1797A can also be used during the evaluation and installation of OC-768 and STM-256 transmission systems.

Featuring best-in-class specifications, the MP1797A's internal jitter generator outputs a 39.81312 GHz jittered clock with jitter modulation frequencies up to 320 MHz and modulation amplitudes up to 16,000 UIp-p. Additionally, the jitter generator has a frequency offset function that varies from -100 ppm to +100 ppm. Utilizing both low- and high-pass filters that are defined by ITU-T O.172, the jitter receiver accurately detects and analyzes the clock. In addition to a 1/1 clock, the MP1797A has 1/16 and 1/64 clock outputs so it can perform highly accurate transponder tests.

Measurement accuracy is ensured, in part, by the high-performance MU179701A E/O unit and MU179702A 39.8 Gbit/s O/E module. Used with the jitter generator and a BERT transmitter, the MU179701A converts 25-43 Gbit/s NRZ electrical data to optical NRZ data for transmission. It features a high output power of 0 dBm +/-3 dBm and has a clock delay function of 0/-20 ps in 1 ps steps.

The MU179702A receives the optical data, recovers the jitter clock, and transmits the signal to the jitter receiver. It has a 320 MHz wideband CDR (Clock/Data Recovery), as well as a narrowband CDR of <16 MHz to ensure jitter measurement accuracy. The MU179702A also has wide sensitivity of 0 to -10 dBm. An internal optical power meter is available with the MU179702A.

With the MX179701A jitter measurement application software, all measurements can be performed automatically. In addition, the software can convert jitter transfer and jitter tolerance test results and display them in chart form for reporting purposes.

The MP1797A jitter analyzer pricing is available upon request. Delivery is 20 weeks.
