MEMS SWITCHES SCBU NxM
SCBU: Customizable fiber optic switch and Non-blocking Matrix up to 16x16
Sercalo's fiber optic SCBU NxM switches are bidirectional opto-mechanical switches based on coaxial design where a matrix of MEMS mirrors redirects light from N inputs to M outputs. The optical networks can be based on a strictly nonblocking matrix (from 4x4 up to 16x16 ports) or on a tree structure (up to 1x1116 ports).
The miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards.
The underlying MEMS technology results in low insertion loss and low cross-talk between channels while keeping a constant switching performance over life. The hermetically sealed MEMS and the laser welded collimators guarantee broad temperature range and superior long term stability. The part is designed to conform to Telcordia 1221 reliability standards. No epoxy is present in the optical path.

OVERVIEW

DESCRIPTION
Sercalo’s SCBU fiber optic switches are based on a strictly non-blocking bidirectional architecture. An additional status where the channels are disconnected is available. The switch is non latching: at power-off it breaks the optical connection and routing of ports is not defined. The component is bidirectional, i.e. the common port can be used as input or output of the light signal.
