The Keysight (Agilent) 83437A incoherent light source supports measurement of insertion loss, crosstalk, bandwidth, and polarization dependencies of passive optical components, using up to four EELEDs across five wavelengths: 1200, 1310, 1550, and 1650 nm.
It delivers over 25 dB peak power density in single-mode fiber—outperforming standard white light sources for wavelength-dependent optical testing.
Testwall can supply the used Keysight (Agilent) 83437A, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
