The 818-BB-36F High Speed Battery Biased Fiber-Optic Detector features an extended InGaAs photodiode with a 20 um active diameter and a <16 ps rise time coupled to a Corning singlemode SMF-28e fiber with an FC/UPC connector. It works well in high-frequency heterodyne applications, time domain, frequency response measurements and monitoring output of ultrafast lasers. It includes a built-in battery-powered 3V bias, an on-off switch and an SMA connector output. The batteries are easily replaceable and by disconnecting the detector from the oscilloscope input, when not in use, you can extend the lifetime of the batteries.
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.
An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.
These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the
