The 818-BB-45AF amplified photoreceiver consists of a 1-m long FC/UPC connectorized singlemode fiber coupled to a 500 to 890 nm GaAs high speed detector with a <35-ps rise time. It is an excellent solution for viewing rapid modulation of low-power CW lasers or other light sources in the µW regime. 

The 818-BB-51AF amplified photoreceiver is built from an extended InGaAs photodiode with a 40-µm active diameter and a <35-ps rise time. The device is fiber pigtailed with an FC/UPC connector. With a wavelength range of 1475 to 2100 nm, it allows monitoring Thulium (Tm) and Holmium (Ho) doped lasers as well as other NIR lasers.

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 , when unpacking and handling these devices.
