Sercalo’s latching fiber optic 1xN switches are very fast bidirectional opto-mechanical switches. The underlying MEMS technology permits to obtain low insertion loss combined with high crosstalk between channels. The switch communicates over a UART interface with TTL or RS-232 voltage levels and over a secondary SMBus/I2C or USB interface. sercalo’s highly reliable switching mechanism uses integrated micro-mirrors that can be moved in or out of the optical path by electrostatic actuation. The latching mechanism offers the best repeatability and long term stability. The component is designed to conform to Telcordia 1221 reliability standards.
