SN Series Fiber Optic MEMS Switches

Center Wavelength 400 to 2050 nm; Insertion Loss Typ. 0.5 to 1.0 dB; Return Loss ≥40 to ≥70 dB; Polarization Extinction Ratio 20, 30; Fiber Type SM, MM, PM OZ Optics’ FOP series of fiber optic polarizers are designed to polarize the output from a light source or fiber and launch it into an output fiber. These polarizers typically consist of input and output collimators with a plate polarizer in between. Broadband polarizers are used, so the power extinction ratio is maintained for up to several hundreds of nanometers. The same polarizer, for example, may be used for 1300 nm to 1600 nm. The power extinction ratio is the ratio between maximum and minimum output power as the input polarization state is changed. This is different from the output polarization extinction ratio, which is a measure of the ratio between the power in the two axes of polarization maintaining fiber – this value is only applicable when the output fiber is polarization maintaining (PM) fiber. The power extinction ratio will always equal or exceed the polarization extinction ratio. OZ Optics offers fiber optic polarizers in four sizes. The original 12.5 mm diameter size is best suited for non-telecom wavelengths and for custom designs. The larger size is also well suited for high power applications. Polarizers capable of transmitting several Watts of power have been made with this technique. The 5.5 mm diameter size is well suited for telecom wavelengths, such as 1310 and/or 1550 nm, while the 4 mm diameter option is best suited for low-cost systems where lower output extinction ratios are acceptable. Finally, OZ Optics offers a version that is only 3 mm in diameter, featuring exceptionally low return losses and superior performance over a very broad temperature range.

Non-latching; 1x2 to 1x32; Fiber Type SM, MM; 1240 to 1640 nm; Insertion Loss 0.5 to 2.5 dB; Crosstalk 60 dB; Switching Time 1 to 20 ms Sercalo Microtechnology’s SW series are very fast, opto-mechanical switches based on the MEMS technology. These non-latching MEMS switches available both for single mode (SM) and multi mode (MM) fibers in 1x2, 1x4, 1x8, 1x13, 1x16, 1x32 and 2x2 configurations. All SW series 1xN components are designed to establish an optical connection between one optical port and either one of up to 32 input or output lines in a very short time, while the 2x2 variants are designed for optical cross connect switching in single mode (SM) or multi mode (MM) fiber networks. Powered by a 5 VDC supply voltage, the SW series switches allow to control the switching state with a 5 V TTL or CMOS drive signal. The switching mechanism offers the reliability of a solid state device; it neither wears out nor degrades over time. Even after billions of cycles the switching quality stays constant. The SW series’ highly reliable switching mechanism uses integrated micromirrors, features fast switching times down to below 1 ms for some models and shows only 0.5 to 2.5 dB insertion loss. With its MEMS switching structure, the SM series of fiber optic MEMS switches achieves repeatability of 0.001 dB and shows a very flat insertion loss over the full spectrum of the fiber. The miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards. The SM switch series is qualified according to Telcordia GR 1221 and mainly used in test and measurement applications. Key Features: Reliable Insertion Loss (IL): 0.5 to 2.5 dB Response Time: 1 to 20 ms Crosstalk: 60 dB Miniature Size Non-latching Applications: Optical Reconfiguration; Protection Switching; Network Restoration  

Non-latching; 16x16, 24x24, 32x32; Fiber Type SM, MM; 1240 to 1650 nm; Insertion Loss 0.5 to 2.5 dB; Crosstalk 60 dB; Switching Time <100 ms Sercalo Microtechnology's OCX series of NxN fiber optic matrix switches are non-blocking devices that connect any of the input fibers to any of the output fibers. These 16X16 up to 32x32 optical cross connects are using an optical free space technology. Over a RS232 or USB interface the individual ports can be addressed. The optical connections are set by a 3D MEMS switch network, where micromachined silicon mirrors redirect light from the specified input port to the selected output port. The use of MEMS technology offers low cost together with excellent optical performance. The OCX series of fiber optic cross connects is built using Sercalo Microtechnology’s established MEMS technology. The MEMS mirrors are stable enough to operate the switch in open loop. The switch is fully bi-directional and transparent to the full wavelength range of the installed fiber. The switch architecture is non-blocking: Any of the input ports can go to any of the free output ports. This hitless non-blocking switch for demanding applications in fiber optic instrumentation or communication is currently in initial production with port counts up to 32x32. The switch is designed for integration into a network system. Key Features: Non-blocking Fully Bi-Directional Reliable Wavelength Range: 1240 to 1650 nm Low Insertion Loss: 0.5 to 2.5 dB Switching Time: <100 ms Standard Port Counts: 16x16, 24x24, 32x32 Custom Port Count NxM Available on Request Crosstalk: 60 dB Single Mode (SM) or Multi Mode (MM) Fiber UART and USB Interfaces Applications: Optical Network Switching; Fiber Optic Cross Connect; Fiber Optic Test and Measurement; Data Center Optical Switching

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). Key Features: Low Insertion Loss Reliable Non-latching Bidirectional 1xN, 2xN, NxM Variants Up to 2x540 Optical Ports Wavelength Range: 1250 to 1670 nm Insertion Loss (IL): 0.4 to 2.5 dB Response Time: 5 to 10 ms Crosstalk: 60 dB UART, I2C/SMBus and Parallel Interface Ethernet Interface Available on Request RoHS Compliant Applications: Telecom; Optical Network Switching, Reconfiguration, Protection and Restoration; Instrumentation; Test and Measurement

Latching; 1x2 to 1x16; Fiber Type SM, MM, PM; 1240 to 1640 nm; Insertion Loss 0.5 to 1.6 dB; Crosstalk 60 dB; Switching Time 1 to 10 ms Sercalo Microtechnology’s SL series are fast, latching opto-mechanical MEMS switches for the most demanding applications in fiber optic communication networks. They maintain the last switching state after power is removed and are available in configurations 1x2, 2x2, 1x4, 1x8 and 1x16 with a variety of driver options and a capacitive position sensor (SLTS variants). SL series switches are the best choice where highest reliability and self test capability are required. The SL series’ highly reliable switching mechanism uses integrated micro-mirrors that can be moved in or out of the optical path by electrostatic actuation. This latching mechanism offers the best repeatability and long term stability, has a very fast response time down to below 1 ms for some models and only 0.5 to 1.6 dB insertion loss. The underlying MEMS technology permits to obtain low insertion loss combined with high crosstalk between channels. 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. The switching mechanism offers the reliability of a solid state device; it neither wears out nor degrades over time. Even after billions of cycles the switching quality stays constant. 1x8 and 1x16 models communicate over a UART interface with TTL or RS-232 voltage levels and over a secondary SMBus/I2C or USB interface.
