The Agilent N7788B Optical Component Analyzer's proprietary technology is comparable with the well-known Jones-Matrix-Eigen analysis (JME) which is the standard method for measuring polarization mode dispersion (PMD) or differential group delay (DGD) of optical devices. For spectral measurements of polarization dependent loss and dispersion, the N7788B is combined with a Keysight swept-wavelength tunable laser, such as the 81600B or 81960A (not included) and the Polarization Navigator software application for single-scan measurements. Specifications. Specification wavelength range: 1270 nm to 1375 nm (Opt. 300, O-Band), 1270 nm to 1375 nm and 1460 nm to 1620 nm (Opt. 400, O/C/L-Band), 1460 nm to 1620 nm (Opt. 500, C/L-Band). Operating wavelength range: 1260 nm to 1640 nm. Differential group delay (DGD) uncertainty: Resolution 2.0 nm ± (30 fs + 3.0% * DGD), Resolution 0.1 nm ± (30 fs + 3.0% * DGD). DGD measurement range: 3 0 ps to 1000 ps. PMD repeatability: (typical) ± 3 fs. PDL uncertainty: C-Band ± (0.05 dB + 4% * PDL), O-Band ± (0.10 dB + 4% * PDL). Polarization analysis SOP uncertainty (typical): 1.5°. Optical power measurement Relative uncertainty: C/L-Band; ± -.03 dB (± 0.02 dB typical), O-Band; ± 0.07 dB (± 0.04 dB typical). Options. 021, Straight contact connector (laser input port). 022, Angled contact connector (laser input port). 031, Straight contact connector (DUT port). 032, Angled contact connector (DUT port). 300, 1270 to 1375 nm wavelength. 400, 1270 to 1375 nm and 1460 to 1620 nm wavelength. 500, 1460 to 1620 nm wavelength.
