EXFO WA 7600

The Exfo WA-7600 Multiline Optical Channel Analyzer uses Michelson interferometer-based WAVEMETER technology to determine the absolute wavelength of an optical signal under test by comparing its interference fringe pattern with that of a built-in HeNe laser wavelength standard. Wavelength Range: 1270 to 1680 nm (178 to 236 THz). Wavelength Uncertainty: ±0.2 ppm. Wavelength Minimum resolvable separation: 30 pm. Wavelength Display resolution: 0.0001 nm. Power Uncertainty: ± 0.5 dB (at ± 30 nm from 1310 and 1550 nm). Power Linearity: ± 0.3 dB. Power Display resolution: 0.01 dB. Optical Input Signal Sensitivity, single line input: -40 dBm (0.1 µW), 1270 - 1600 nm; -30 dBm (1.0 µW), 1600 - 1680 nm. Maximum input level (sum of all lines): + 10 dBm (10 mW). Maximum safe level (sum of all lines): 18 dBm (63 mW). Optical Dynamic Range Signal-to noise ratio (lines above -25 dBm): > 35 dB, channel spacing >= 100 GHz; > 27 dB, channel spacing >= 50 GHz. Number of Laser Lines Input: Maximum 256. Measurement Cycle Time: 1.25 s (0.8 measurements/s). Instrument interface: GPIB (IEEE-488.2), RS-232, floppy disk drive, VGA monitor port, parallel printer port.
