Anritsu Company introduced a Stressed Eye Measurement Suite for its MP1800A series of Signal Quality Analyzers that offers desirable repeatability for measuring the average output power level difference (OMA), extinction ratio, and Vertical Eye Closure Penalty (VECP) of optical signals. The hardware and software suite provides designers and manufacturers of 10GBASE-L/10GBASE-E optical modules and transmission equipment with an instrument that reduces measurement times and increases efficiency. The suite supports stressed receiver conformance to ensure products are IEEE802.3-2005 compliant. The configuration creates excellent reproducibility because it eliminates the need to capture data under various measurement environments using different connection cables at numerous ambient temperatures. OMA, extinction ratio, and VECP measurements can be made with a power penalty of ±0.3 dB, ensuring precise measurements, when the MP1800A’s high-accuracy, auto-calibration function is used. The transmitter supports output of both 1310 nm and 1550 nm wavelengths, and the control software supports power penalty tests, jitter tolerance margin measurements, and jitter sweeps for jitter tolerance GO/NO GO checks.
