Fiber-Optic Detector, 830-2150 nm Battery Biased Extended InGaAs, 10 GHz, FC/UPC

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.

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.

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 FK-STRAP, when unpacking and handling these devices.
