The Ando AQ6140 Multi-Wavelength Meter has been developed as a measuring instrument compatible for the characteristic evaluation of WDM (wavelength divided multiplex) systems and Fabry-Perot laser multiplexing. The wavelength measurement range is 1270 to 1650nm, and up to 256 laser beams can be measured simultaneously. The GP-IB and RS-232-C interfaces are provided as a standard allowing remote control. Specifications. Wavelength range: 1270 to 1650nm. Wavelength accuracy: ±2ppm (1550nm, 1310nm; ±0.003nm). Minimum resolvable separation: 10 GHz or less (1550nm; 80pm, equal powerline input). Power accuracy: ±0.5dB (1310/1550 ±30nm, typ.). Level linearity: 1270 to 1600nm; ±0.3dB (input -30dBm or more). Polarization depending loss. 1270 to 1600nm; ±0.5dB, 1600 to 1650nm; ±1.0dB. Maximum number of line input: 256. Minimum input level: 1270 to 1600nm; -40dBm ( 1 line input), 1600 to 1650nm; -30dBm ( 1 line input). Maximum input level: + 10dBm (total of all lines). Return loss: 35dB(PC). Dynamic range: 35dB or more (noise band width: 0.1 nm.input: -25dBm or more (spacing >=; 100GHz). Measurement time: 1.5 sec (typ.). Applicable fiber: SM. Display: 6.5·inch color LCD (640 X 480 dots). Interfaces: GP-IB, RS-232C, VGA,printer port(centronics), FDD.
