AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81618A / 81623A / 81623B / 81626B is a comprehensive lightwave test set designed to help engineers troubleshoot and characterize optical and hybrid components. The 4 instruments offer the flexibility necessary to support the demands of today's sophisticated optical technology. The 81618A is the most comprehensive of the instruments, offering a combination of high accuracy and portability. The optical power meter and light source together provide loss measurements from 110 dB down to -75 dB in wavelength-independent mode. The 81618A also supports wavelength-dependent measurements from 1.25 to 1.72 microns, an ideal range for single-mode fiber applications and for EMI/RFI testing. The 81618A's complements include several optional accessories like an integrated test head for power measurements without the need for external adapters. The 81623A is a high-sensitivity lightwave multimeter offering a wide dynamic range and repeatability of optical power measurements down to -60 dB across a wide wavelength range from 1.25 to 1.72 microns. It can also measure absolute power levels (up to 15 dBm), as well as monitor relative power changes with its unique differential capability. The 81623A can be coupled with a variety of adapters and test heads to enable a range of applications, such as return loss and splice loss measurements. The 81623B is a four-channel lightwave multimeter ideal for characterization of fiber-optic systems. The 81623B provides a combination of extremely high accuracy, wide dynamic range, and extended wavelength capabilities. It measures both single-ended and differential optical power values in four independent channels. The 81623B can be connected to various adapters and test heads for a variety of applications, such as OTDR (optical time-domain reflectometry) measurements, loss and reflected power measurements, and end-to-end loss or distance measurements. The 81626B is a measurement tool designed for testing hybrid systems using both waveguide and optical components. The 81626B is engineered to measure waveguide and hybrid fibers from the 1300 to 1650 nm wavelengths. The 81626B supports a variety of waveguide parameters, including insertion loss and return loss. Its Bessel resolution function mode offers waveguide integration times up to 10 ms, resulting in greater accuracy and precision. Overall, HP 81618A / 81623A / 81623B / 81626B provide an excellent solution for optical and hybrid testing in both laboratory and field environments. The 4 instruments offer complete optical measurement capabilities and the flexibility and accuracy necessary for today's challenging requirements.
