MEMS 1X2 SWITCH
DiCon’s MEMS 1x2 is based on a micro-electromechanical system
(MEMS) chip. The MEMS chip consists of an electrically moveable
mirror on a silicon support. A voltage applied to the MEMS chip
causes the mirror to rotate, which changes the coupling of light
between a common fiber and two input/output fibers. The MEMS
1x2 Switch is a non-latching device, which acts as a shutter when
electrical power is removed.
FEATURES
Small optical switch package
Based on DiCon’s proven MEMS platform
TTL parallel or SMBus/I

C serial control interface
Qualified to Telecordia GR-1221
APPLICATIONS
The MEMS 1x2 Switch is often used in channel or band monitoring cards
to reduce the size and cost of monitoring DWDM networks. Other applica-
tions inlude fiber-based sensing, side-select switching for redundancy and
secure communications, and bio-medical and scientific research. Excellent
reliability, repeatability and temperature performance makes the MEMS
1x2 switch ideal for temperature and environmental sensing equipment, as
well as channel monitoring cards.
