Optical Test Set Agilent 8140A
Agilent / HP 8140A is a handheld Optical Loss Test Set. The 8140A Loss Test Set includes 8140A Loss Test Set Mainframe, 81401A Optical Sensor Module InGaAs-PD 700-1700nm (850, 1300, & 1500nm), and 81412A LED laser source 1300nm.

The HP 8140A is a compact, lightweight instrument for hand-held operation in the installation and maintenance of optical links and component characterization. It may be configured as a power meter, a stand-alone source, or a loss test set. As a power meter, it is an ideal tool for the measurement of the output power of transmitter modules and of power levels at the fiber end, and for the check for "dark" fibers.
The HP 8140A, in a standalone source or loss test set configuration, covers all wavelengths commonly used in datacom LANs and telecommunications networks. Its main applications include the insertion loss of optical passive components and the total link loss to check for power budgets
