The Ando AQ3540 Optical Channel Selector is a precision instrument for automated optical signal routing and channel isolation in fiber-optic networks. It selects and directs specific optical channels to enable detailed signal analysis across Single Mode and Graded Index fiber systems. Available in 1×16 and 2×16 configurations, the AQ3540 routes signals between common I/O ports (COM1 and COM2) and 16 selectable channel ports (CH1–CH16), supporting bidirectional switching with minimal signal degradation.
The device operates across the 1200 nm to 1650 nm wavelength range with typical insertion loss of 2.5 dB or less (1.2 dB on specific models) and maximum insertion loss of 4.5 dB. Selection repeatability is exceptional—0.003 dB typical—ensuring consistent performance across millions of switching cycles. Return loss reaches 45 dB or 60 dB depending on configuration, while crosstalk measures -65 dB or less. Polarization dependency loss remains below 0.05 dB P-P (typical 0.02 dB P-P), critical for maintaining signal integrity in polarization-sensitive measurements.
