Fiber optic 1xN switches are bidirectional opto-mechanical switches based on a coaxial design where a single MEMS
mirror redirects light from a common fiber to one of N ports. The underlying MEMS technology results in low insertion loss and low
crosstalk between channels while keeping a constant switching performance over life. In the bare switch (BMSW type) the state is
set using 4 lines of 0-40V analog voltage. The internal MEMS is NOT ESD protected and needs special care during handling. The
MEMS component is hermetically sealed and the fiber collimater is laser welded for superioir long term stability. No epoxy is
present in the optical path.
The COAXIAL TYPE 1xN switch is non latching and breaks the optical connection at power-off, i.e. the common port is not routed
to any port and the optical path is open. The switch works over a single band at specified performance. When the wavelength
range covers more than one band, the insertion loss increases, but the switching function is still performed. Information in this
datasheet is believed to be correct but The reserves the right to change specifications without notice at any time.
