The JDSU 5071 WDM C-band WDM plug-in module for the MTS 5100/5200 family tests all the parameters necessary for maintenance of the DWDM network, including channel wavelength, frequency, channel spacing, power and optical signal to noise ratio (OSNR). To speed multiple fiber testing, 5071 WDM module features a macro function which can be user-programmed for automatic, successive measurement and analysis of large quantities of fibers. The 5071 WDM module can be used for statistical analysis of the results of long-term monitoring. User-defined limits identify potential problems, for effective preventative maintenance of the network. Wavelength parameters; Range: 1525 to 1570 nm. Display resolution: 1 pm. Accuracy: +/- 35 pm (+/- 20 pm typical). Minimum channel spacing: 0.2 nm (12.5 Ghz). Power level parameters; Display range: -90 to +30 dBm. Display resolution: 0.01 dB. Accuracy: +/-0.5 dB (-30 dBm, 1550 nm). Linearity (typical): +/- 0.1 dB (-40 to +10 dBm). OSNR (0.1nm bandwidth): 33/29 (0.8 / 0.4 nm). Polarization dependance: +/-0.2 dB. Optical return loss: >35 dB. Sweep time: 1 s (real time).
