SL 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

Sercalo Microtechnology's VXA series of miniature MEMS variable optical attenuators (VOAs) has been discuntinued by the supplier. For replacement and new projects, please refer to the mVOA series of ultra-small or VXP1 series of miniature MEMS variable optical attenuators (VOAs). MEMS-based, Pigtail Style, Transmission Mode; Single/Dual Types; Fiber Type SMF28; 1240 to 1640 nm; Attenuation up to 30 dB Sercalo Microtechnology's VXA series of miniature MEMS variable optical attenuators (VOAs) is ideal for fiber optic communication systems and submodules. The non-latching attenuators work in transmission mode and allow for the continuous adjustment of the attenuation with a 0 to 5 V control voltage. The highly reliable attenuation mechanism is based on a micromechanical shutter – a silicon MEMS chip, on which a mirror can be moved in and out of the optical path by electrostatic actuation – and features below 2 ms response time and below 1 dB insertion loss. The VXA variable optical attenuators are composed of an optical subsystem and an electrical driver interface. VXA series is available in single (VXA1) and dual (VXA2) variants and normally open or normally closed designs. The plastic package is one of the smallest in the industry and optimized for low cost production while maintaining high reliability comparable to a solid-state device. The component is designed to meet Telcordia 1221 quality standards. The standard VXA attenuator achieves minimum insertion loss at 0 V input voltage. The VXAxOF variant is normally closed, i.e. at 0 V the attenuation is maximum and is reduced with increasing input voltage. Key Features: Small Size (23 x 10 x 6 mm) Low PDL Very Fast 0 to 5 V Control Single or Dual Channel Applications: Power Management in DWDM Transceivers; Amplifier Gain Control; Optical Subsystems; Array Integration
