(PM)VOA Variable Optical Attenuators

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. Key Features: Rugged and Compact Size Wide Wavelength Range Single Mode, Multi Mode and Polarization Maintaining Fiber Versions Low PDL and Wavelength Dependency High Power Handling Wide Attenuation Range Low Backreflection Designed to Meet Telcordia Requirements Applications: Optical Power Equalization and Power Control for WDMs and Multi-channel Optically Amplified Networks; Telecommunications; CATV; LAN; Test and Measurement; Receiver Padding; Optical Sensors

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.
