Fiber optic switching system

Dow-Key

Dow-Key is excited to announce a new addition to their switching product line - Model 7001 - which is the first in Dow-Key Microwave's series of fiber optic switching systems.

This model switches signals in pure optical domain with an operating wavelength of 1530-1565 nm in C-band and a data rate of 4 Gbps. The system is configured partially as crossbar and partially as fan-out, with 8x14 I/O ports using LC connectors. On the control side, the unit is equipped locally with a windows based touch screen and with a modern GUI (Graphical User Interface) on the front panel that allows the user to graphically set the desired paths.

This pure optical switching is based on MEMS (Micro ElectroMechanical Systems) technology, where these switches utilize micro-mirrors to switch or reflect an optical channel or signal from one location to another depending on the relative angle of the micro-mirror. MEMS technology provides durability and reliability such that the life of the switches exceed 1,000,000,000 (one billion) cycles. Additionally, MEMS provide a technology of reduced size, power, and cost in comparison to electromechanical switches. As a result, the advantage at the system level for small optical matrices compared to a pure electromechanical system is that such systems cost much less, has lower insertion loss, and in general, has higher repeatability and higher production yield.
