SW Series Fiber Optic MEMS Switches

MEMS-based, Coaxial Style; Fiber Type SM (SMF28ultra, ZBL, SM600/850/980), PM (HP850/908PM); 650 to 1670 nm; Fiber Length 50 to 100 cm; Attenuation up to 30 dB, 40 dB Sercalo Microtechnology’s mVOA series of coaxial ultra-small fiber optic variable optical attenuators (VOAs) is based on an electrostatic MEMS mirror. It comes in a hermetically sealed package with a diameter of only 3.5 mm, and the devices are manufactured with the latest techniques in laser welding for achieving better stability and improved reliability. A voltage between 0 and 6.5 V on the drive pin sets the optical attenuation. When power is removed, the VOA returns into its default state. There are two variants available with different default states: normally open (bright) or high attenuation (dark). The dark variant has better linearity and is used in applications where the light is cut at power off. The mVOA series is designed to conform to Telcordia 1221 reliability standards. No epoxy is present in the optical path. The optical collimator is assembled using laser welding techniques which results in long term stability and excellent reliability. The components withstand rugged environments and can directly be mounted on printed circuit boards. This ultra small mVOA series is compliant to ROHS requirements 2011/65/EU and ideally suited for gain control in amplifiers and transceivers. Key Features: Diameter 3.5 mm Laser Welded Package Reliable- 0 to 6.5 V ROHS compliant Applications: Telecom; Instrumentation; 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).
