MULTIFUNCTION WDM TESTER WITH 0.1-nm RESOLUTION
Oct 1997Anritsu Co.Request Info
Anritsu says its new MS9715A WDM tester can be used at virtually any stage from manufacturing through maintenance. It operates from 1527 to 1567 nm and has a long-time measurement function that makes it suitable for maintenance and monitoring. Within this function, a built-in wavelength-standard light source automatically performs wavelength calibration to maintain accurate wavelength measurement. The instrument can measure signal-to-noise ratio, channel spacing, gain slope and spectrum. It has ±20-pm linearity and ±50-pm accuracy with a dymanic range of 53 dB at 0.5 nm and 58 dB at 1 nm. Polarization dependence loss is ±0.25 dB.
