1 Insertion loss is optimized for one band. If the switch is operated over all four bands add 0.5 dB to IL.
Band is selectable over software between 1310, 1550 nm
2 Value @ 25 °C, without connectors.
3 It is recommended to switch off the laser during switch transients when switching high optical power above
50 mW
4 For constant temperature and polarization.
5 Through onboard pull-up resistor.
