General description of the
used AGILENT 86120B
for sale.
The Agilent 86120B Multi-Wavelength Meter measures the wavelength and optical power of laser light in the 700- 1650 nm wavelength range. Because the Agilent 86120B simultaneously measures multiple laser lines, you can characterize wavelength-division-multiplexed (WDM) systems and the multiple lines of Fabry-Perot lasers.. Parameters: Wavelength Specifications; Range: 700 to 1650. Absolute accuracy (lines separated by >=30 GHz): ±3 ppm (±0.005 nm at 1550 nm and ±0.004 nm at 1310 nm). Differential accuracy (characteristic): ±2 ppm. Minimum resolvable separation (characteristic): 20 GHz (0.16 nm at 1550 nm, 0.11 nm at 1300 nm). Display resolution: 0.001 nm, normal update mode. Amplitude Specifications; Calibration accuracy at calibration wavelengths ±30 nm: ±0.5 dB (at 1310 and 1550 nm), 780 nm (characteristic). Flatness, ±30 nm from any wavelength: 1200 to 1600 nm (characteristic) ±0.2 dB, 700 to 1650 nm (characteristic) ±0.5 dB. Linearity, 1200 nm to 1600 nm, lines above -30 dBm: ±0.3 dB. Polarization dependence: 1200 to 1600 nm ±0.5 dB, 700 to 1650 nm (characteristic) ±1.0 dB. Display resolution: 0.01 dB. Sensitivity Specifications; Single line input: 700 to 900 nm: -20 dBm, 900 to 1200 nm: -25 dBm, 1200 to 1600 nm: -40 dBm, 1600 to 1650 nm: -30 dBm. Multiple lines input (characteristic): 700 to 1650 nm, 30 dB below total input power, but not less than single line input sensitivity. Selectivity Specifications; Two lines input separated by >= 100 GHz (characteristic): 25 dB. Two lines input separated by >= 30 GHz (characteristic): 10 dB. Input Power: Maximum displayed level (sum of all lines) +10 dBm, Maximum safe input level (sum of all lines) +18 dBm. Maximum Number of Laser Lines Input 100. Input Return Loss; With straight contactconnectors: 35 dB, With angled contact connectors (Option 022): 50 dB. Measurement Cycle Time; Normal update mode (characteristic): 1.0 s (1 measurement-per-second). Signal-to-Noise Ratio (characteristic); channel spacing >= 200 GHz: >35 dB (0.1 nm noise bandwidth), lines above -25 dB
