Agilent Technologies N7788B
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. Wavelength Particularly for characterizing optical filters, the high dynamic range of the N7788B allows accurate resolution of the filter’s side lobes.| Part No. | N7788B |

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 switch provides continuous self calibration for excellent repeatability. Resolving TE/TM insertion loss The TE/TM-function allows accurate determination of the minimum and maximum loss of the DUT at each wavelength. Due to birefringence, optical filters tend to show different transmission functions depending on the polarization state.
