N7788B bench-top mainframe Introduction Agilent Technologies pushes the limits of component measurements with the N7788B component analyzer.
Its proprietary technology is comparable with the wellknown Jones-Matrix-Eigenanalysis (JME) which is the standard method for measuring polarization mode dispersion (PMD) or differential group delay (DGD) of optical devices.
Compared to the JME, Agilent’s new single scan technology offers a range of advantages: A complete set of parameters: ● DGD/PMD ● PDL ● Power/loss ● TE/TM-loss www.

com ● Jones matrices ● Mueller matrices ● 2nd-order PMD (depolarization + PCD) ● Principal states of polarization (PSPs) Key Benefits ● Highest accuracy in a single sweep: no averaging over multiple sweeps required ● High measurement speed: Complete measurement across C/L-band in less than 10 seconds (no need to wait for many averages) ● Robustness against fiber movement/ vibration and drift: Fixing fibers with sticky tape on the table or even operation on isolated optical table is not required! ● No limitation on optical path length of component ● The internal referencing scheme guarantees reliable and accurate measurements.
Applications ● ● ● ● ● Fiber characterization: SMF, PMF, DCF Passive component testing: filters, isolators, circulators Dynamic component / module testing: OADM / ROADM Active component testing: EDFAs, SOAs, VOAs Link test: in-channel measurements across amplifiers The instrument setup is shown in the Figure 3.
A LiNbO3 polarization controller determines the input polarization to the DUT.
While the tunable laser source is sweeping over the desired wavelength range, a polarimeter analyzes the output state of polarization while input polarization is being modified.
The result will be a highly accurate device characterization with respect to DGD/PDL/loss, etc.
Furthermore, the internal optical swi...
