MMVOA Variable Optical Attenuators

MEMS-based, Pigtail Style, Reflection Mode; Single/Dual Types; Fiber Type SMF28; 1240 to 1640 nm; Attenuation up to 30 dB Sercalo Technology’s VXP series of miniature MEMS variable optical attenuators (VOAs) comes in a very small package and is ideally suited for integration in subsystems, where cost, size and performance are the most critical factors. The non-latching attenuators work in reflection mode and allow for continuous adjustment of the attenuation with a 0 to 5 V control voltage. The VXP variable optical attenuators are composed of an optical subsystem and an electrical driver interface. 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 20 ms response time and below 1.0 dB insertion loss. The VXP series of miniature VOAs is available in single (VXP1) and dual (VXP2) variants. 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 VXP attenuator achieves minimum insertion loss at 0 V input voltage. When power is removed, the insertion loss is roughly 0.5 dB higher than the minimum insertion loss (at 0 V when power is on). 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

Polarization Maintaining; 480 to 1625 nm; Fiber Type PANDA, others; Insertion Loss ≤0.4 to ≤1.5 dB; Operating Temperature Range -20 to +70 °C OZ Optics’ PMJ series of polarization maintaining (PM) patchcords are based on a high precision butt-style connection technique. The PM axis orientation is maintained by using male connectors with a positioning key and a bulkhead female receptacle with a tightly toleranced keyway, ensuring good repeatability in extinction ratios and insertion losses.The polarization axis of a fiber is aligned with the connector key by rotating either the connector frame or the fiber itself until the polarization axis is in line with keyway of the connector. Once the fiber is correctly aligned, the alignment can be fixed with a drop of glue or epoxy. OZ Optics minimizes backlash and rotational errors in the PM axis alignment by using specially designed PM ferrules and connector housings.Patchcords are normally offered pre-aligned and referenced with the slow axis aligned to the connector key for optimum coupling efficiency and extinction ratios. Non-angled FC PM connectors are also available unaligned and unlocked (rotatable) for lab use. Unless otherwise specified, pre-aligned patchcords are oriented such that the slow axis of the fiber is aligned with the key of the connector and locked. These patchcords maintain polarization to better than 20 dB. Higher extinction ratios are available upon request. In general, OZ Optics uses polarization maintaining fibers based on the PANDAfiber structure when building polarization maintaining components and patchcords. However OZ Optics can construct devices using other PM fiber structures, including 80 µm cladding sizes. If necessary, OZ Optics is willing to use customer supplied fibers to build devices. OZ Optics uses a 2.00 mm housing key for its standard FC/PC PM connector design. This is known also as a type “R” keywidth. Also available are FC/PC connectors with a 2.14 mm housing key (Type “N”). Sleeve through adaptors are available to connect same size keys or to convert from a 2.00 mm to a 2.14 mm key connector. In addition to patchcords and sleeve through adaptors, OZ Optics provides male PM connectors and ferrules for fiber termination, bulkhead receptacles to attach fibers to devices as well as ferrules for different fiber sizes. Key Features: Terminations Available: FC/PC, SC, ST, LC, MU, E2000 Custom Ferrule Terminations Available High Extinction Ratios (20 dB to 40 dB) Low Insertion Losses (<0.2 dB typ.) Custom Angles Available Compatible with Industry Standard Connectors Designed to Meet Telcordia Specifications Applications: High-speed (10 Gbs / 40 Gbs) Telecommunications; Interferometric Sensors; Integrated Optics; Fiber Amplifiers; Coherent Telecommunications

Hybrid FC - Type R/N (Wide/Narrow Key); Oval; Zirconia Sleeve; Simplex; SM/PM Universal connectors allow one to mate together fibers with different connector types, as long as they are polished the same way.

MEMS-based, Pigtail Style, Broadband; Single/Dual Types; Fiber Type Single Mode; 1240 to 1640 nm; Attenuation up to 45 dB Sercalo Technology’s VP series of MEMS-based, broadband variable optical attenuators (VOAs) achieves very low insertion loss and optimized polarization dependent loss characteristics. The VP series of variable attenuators allows 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 – moving an obstructing element into the optical beam between two single mode fibers – and features below 2 ms response time and only 0.5 dB insertion loss. The position of the obstructing element can be adjusted by an integrated electrostatic actuator, resulting in a fast and hysteresis free response. The low insertion loss and the fast response time make the VP series of VOAs ideal components for active power tuning in WDM networks. Their miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards Key Features: Reliable Low Insertion Loss (0.4 dB) Fast Response Time (2 ms) Low PDL Miniature Size Non-latching Remote Attenuation Control EDFA Control Applications: Power Management in DWDM Transceivers; Remote Attenuation Control; EDFA Control

Blocking, Pigtail Style; Fiber Type SM, MM, PM; 350 to 2050 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation up to 80 dB OZ Optics’ BB-100/400/500/700-11 series of compact PC board mountable blocking pigtail style variable attenuators with low backreflection are designed to meet Telcordia standards. These attenuators can be used for 1300 nm and 1550 nm as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirements The attenuators consist of two collimating lenses, prealigned for optimum coupling efficiency. A threaded radial screw is used to block the collimated beam between the two lenses. Because the attenuator works by directly blocking the beam, it is polarization insensitive. A seal cap is used to seal the junction against temperature and humidity effects. The attenuator can even withstand immersion in water for extended periods of time. Variable attenuators are offered with single mode, multi mode, or polarization maintaining fibers.
