Optical spectrum analyzer
The OSP-102 optical spectrum analyzer performs power and wavelength measurements of individual carriers in amplified narrowband systems in which 1550-nm SDH/Sonet signals are being transmitted simultaneously on multiple carriers. Used as a portable or benchtop instrument, it features a tunable optical filter covering wavelengths from 1520 to 1580 nm. In spectrum-analysis mode, the filter is swept across a selected wavelength range and results are graphically displayed between -70 and +17 dBm. Maximum available power input is 23 dBm. When used with a monitor output, the unit makes bit-error measurements in a selected channel of a multicarrier system without degrading the other channels. When configured with an opto-electronic converter, the analyzer makes eye-pattern measurements. The unit costs $25,237.
