Fiber-Optic Detector, 1000-1650 nm Battery Biased InGaAs Detector, 15 GHz, FC/UPC

The 818-BB-35F High Speed Biased Fiber-Optic Detector features a 1 meter long FC connectorized singlemode fiber coupled to a 1000 to 1650 nm InGaAs detector with a 0.032 mm active diameter and a <25 ps rise time. It includes a built-in bias supply consisting of two standard 3 V lithium cells (6V total bias) and a 50 ohm BNC connector output. The photodetectors have an internal 50 Ω termination. As the responsivity data is applicable to the diode only, the detector output should be determined based on 1/2 the responsivity of that shown on graph. It is a low-cost solution for ultra-fast measurements up to a 15 GHz bandwidth. These detectors are suitable for applications where detector rise time of <25 psec are required for Q-switched and Ultrafast Laser output analysis. 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. 818-BB Series Biased Photodiode Detectors are cost effective diagnostic tools suitable for a variety of high speed applications such as viewing of Q-switched, mode-locked, or rapidly modulated laser signals and picosecond laser alignment. It is equivalent to Coherent's Model ET-3500F (P/N 120-10068-0001).
