BB-200 Variable Optical Attenuators
Product information "BB-200 Variable Optical Attenuators"
Blocking, Receptacle Style; Fiber Type SM, MM, PM; 350 to 2050 nm; Connector Type (Receptacle) NTT-FC/PC, ST, SMA 905, SC; Attenuation 2 dB to 80 dB
OZ Optics’ BB-200 series of blocking receptacle style variable attenuators consist of two baseplates with lenses. The two baseplates are aligned for optimum coupling efficiency using a patented alignment technique. A threaded radial screw is used to block the collimated beam between the two lenses. Rotating the screw changes its position within the collimated beam, thus varying the power level coupled into the receiver fiber. Because the attenuator works by directly blocking the beam, it is polarization insensitive.
Because of limitations in receptacle tolerances, receptacle style attenuators are not recommended for single mode or polarization maintaining applications requiring low losses and good repeatability. Instead, please refer to the OZ Optics BB-100/400/500/700-11 series of blocking pigtail style variable attenuators.
