Features

  • Eight Fixed, Stub-Style BNC Terminators with Resistance Values Ranging from 50 Ω to 250 kΩ
  • One Female-to-Male-to-Female (F-M-F) BNC "T" Adapter Included
  • Packaged in a Compact Plastic Box with Nine Individual Compartments
  • Added Savings Over Individual Resistor Purchases

The FTK01 Fixed, Stub-Style BNC Terminator Kit contains eight terminators with resistance values ranging from 50 Ω to 250 kΩ. One T3285 BNC "T" Adapter (F-M-F) is also included in the terminator kit. When using these terminators, it is necessary to use a BNC "T" adapter to connect both the signal BNC cable and the terminator to the detector. The eight terminators and adapter are packaged in a 7.0" x 3.5" x 1.25" (177.8 mm x 88.9 mm x 31.8 mm) plastic box with nine labeled compartments. The table below provides specifications for each BNC terminator included in the kit. This table is also present on the inside of the box. These terminators and other similar BNC terminators are also available separately.

Thorlabs' stub-style BNC terminators are a compact solution when the resistance value needs to be frequently changed. When using a reverse biased photodiode, such as our packaged biased detectors, a photocurrent is produced when photons are absorbed. A load resistor is placed across the output of the detector, and the voltage drop across the resistor is measured by an oscilloscope or multimeter. A 50 Ω load is typically used to maximize the signal bandwidth, but higher voltages are produced by higher resistances at the expense of lower bandwidth. The image below shows a typical application with our DET100A2 biased detector and our FT502 5 kΩ stub-style terminator.

For kits containing our 50 Ω feed-through terminators, see our electrical adapters kits, which also have a variety of BNC, SMA, and banana adapters.

Terminator Application
Click for Details

A typical application for a stub-style BNC terminator is shown above. The FT502 5 kΩ terminator is connected via a T3285 BNC "T" adapter to an oscilloscope. A BNC cable connects the adapter to our DET100A2 biased detector (not shown). The biased detector outputs a current based on the incident photon flux; the oscilloscope can then measure the voltage across the BNC terminator.
