Battery Biased Fiber-Optic Detectors
Battery Biased Fiber-Optic Detectors
Our battery biased fiber-optic detectors are coupled to a 1 m length singlemode fiber with an FC connector. We have already done the alignment for you with these fiber models as the PIN diodes used for these particular models are quite small (<40 µm).

Features
Biased InGaAs Fiber-Optic Detector
The 818-BB-35F features a 0.032 mm diameter battery biased InGaAs photodetector with a wavelength range of 1000 to 1650 nm. The detector is coupled to a 1 meter singlemode SMF 28e fiber with a FC/UPC connector. The PIN Photodetector utilizes the photovoltaic effect to convert optical power into an electrical current.
Battery Biased GaAs Fiber-Optic Detector
The 818-BB-45F features a high speed 0.04 mm diameter battery biased GaAs photodetector with a wavelength range of 400 to 900 nm. The detector is coupled to a 1 meter singlemode SMF 28e fiber with a FC/UPC connector.
Extended InGaAs Fiber-Optic Detectors
The 818-BB-51F features a high speed 0.04 mm diameter battery biased Extended InGaAs photodetector with an extended wavelength range of 1475 to 2100 nm allowing monitoring of Thulium (Tm) and Holmium (Ho) doped lasers and other NIR lasers. The detector is coupled to a 1 meter singlemode SMF 28e fiber with a FC/UPC connector.
DC to 12.5 GHz Bandwidth
All of these high speed battery biased fiber-optic detectors offer a 3 dB bandwidth from DC to 12.5 GHz. The Frequency response of the 818-BB-51F is shown below.
Measure Pulsewidth or Frequency Response
These high speed detectors make a great fiber-optic front end for a scope or spectrum analyzer. When terminated into 50Ω into an oscilloscope, the pulse width of a laser can be measured. When terminated into a spectrum analyzer, the frequency response of a laser can be measured.
Optical Post Mounting
An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.
Handle With ESD Care
These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the FK-STRAP, when unpacking and handling these devices.
