FOS-1000 Fiber Optic Switches

Non-latching; 1x2, 2x2, 1x4, 1x8; Fiber Type SM, MM; 1240 to 1650 nm; Insertion Loss 1.0 to 2.0 dB; Crosstalk 50 dB; Switching Time 1 ms Sercalo Microtechnology’s BS series are all optical switch solutions for demanding applications in fiber optic instrumentation or communication. The benchtop instrument can switch up to two input fibers to any of up to eight output fibers, independently of data format, wavelength or optical power. The BS series optical switches are available either for single mode (SM) or multi mode (MM) fibers. The optical connections are set by a MEMS based switch network, where micromachined silicon mirrors redirect light to the selected ports. The use of MEMS technology offers solid state reliability together with long term stability and robustness for stable operation. The switch is controlled over an USB connection which also acts as power supply. BS series switches are built using Sercalo Microtechnology’s Telcordia-qualified MEMS technology, which achieves superior reliability and repeatability when compared to traditional mechanical solutions. The switches are fully bi-directional and transparent to the full wavelength range of the installed fiber. When several input fibers are required, the switch architecture can be either blocking or non-blocking. In the blocking architecture when one input is set, the other inputs can only be set to a limited number of “free” ports. In the non-blocking architecture there is no such limitation. Any of the input ports can go to any of the free output ports. But the complexity of the non-blocking architecture is much higher. Key Features: Reliable Low Insertion Loss: Superior Repeatability Single Mode (SM) or Multi Mode (MM) Fibers CE Compliant Applications: Fiber Optic Telecom and Datacom; Fiber Optic Test and Measurement

Non-latching; 1xN, 2xN, NxM; Fiber Type SM, PM; 1250 to 1670 nm; Insertion Loss 0.4 to 2.5 dB; Crosstalk 60 dB; Switching Time 5 to 10 ms Sercalo Microtechnology’s co-axial fiber optic MEMS switches are available in 1xN, 2xN and NxM configurations. Their compact design offers a very low size and lower cost than standard switches. Nevertheless, it has slower speed and larger wavelength dependent loss than the SW or SL types. These co-axial switches are non-latching: at power-off they break the optical connection, and routing of ports is not defined. They are based on a strictly non-blocking bidirectional architecture, i.e. the common port can be used as input or output of the light signal. The underlying MEMS technology results in low insertion loss and low crosstalk between channels while keeping a constant switching performance over life. The hermetically sealed MEMS and the laser welded fiber collimators guarantee broad temperature range and superior long-term stability. No epoxy is present in the optical path. The series of co-axial fiber optic MEMS switches is compliant to Telcordia 1221 reliability standards and RoHS requirements 2015/863/EU. Sercalo Microtechnology’s SC type co-axial 1xN and 2xN fiber optic switches are based on a design where a single MEMS mirror redirects light from a common fiber to one of N ports. The miniature packages withstands rugged environments and is well suited for direct mounting on printed circuit boards. These switches are available in four different variants to simplify integration in existing systems and reduce development cost: standard size – ribbon fibers (SC); miniature size – small driver board: 7 x 40 mm (mSC); compatible with industry pinout, 900 um sleeved fibers and connectors (rSC); bare optical component (bSC). Sercalo Microtechnology’s SCBU type co-axial NxM fiber optic switches are based on a 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 2x540 ports).

To set the state of a switch, a logic level high must be applied to the correspondent pin for at least 20 ms (latching, option A) or continuously (non-latching, option B). All the control pins must remain at a defined potential during use. A capacitive sensor allows reading out the switch position.

Available in 4x4, 4x8 and 8x8 configurations, these switches achieve low insertion loss and high repeatability. For these lower port counts the switches are based on cascaded 2x2 modules. The underlying MEMS technology permits to obtain low insertion loss combined with high crosstalk between channels. Sercalo Microtechnology’s highly reliable switching mechanism uses integrated micro-mirrors that can be moved in or out of the optical path by electrostatic actuation. Light from port A is routed to port B; an optional array of 1x1 switches independently enables or disables the channels of port A. A microcontroller supervises the routing configuration and communicates through an UART interface with TTL (option A) or RS-232 (option B) voltage levels and over a secondary SMBus/I2C (option I) or USB (option U) interface.

With their miniature package, withstanding rugged environments and well suited for direct mounting on printed circuit boards, the SL series switches offer solid state reliability, accurate precision and fast response time and are qualified according to Telcordia GR 1221. Powered by a voltage between 4.0 and 5.25 VDC on the supply pin, the LS series switch’s state is selected with a CMOS or TTL signal on the selector pins. A high pulse during at least 2 ms on one of the selector pins toggles the switch into either cross state or bar state. At 0 V on the selector pins or at power off, the switch remains in the last selected state.
