Main features and technical specifications of high optical output power: +13 dBm wide tuning range: 1465 nm to 1575 nm, built-in wavelength meter provides high accuracy: + /-20pm built-coherent control of stimulated Brillouin scattering suppression Description Agilent 81989A high power compact tunable laser source in the high power level under the conditions of the optical component characterization, and measurement of non-linear effects. Enhance the ability to test all types of optical amplifiers and other active components, as well as broadband passive optical components. As Agilent 8163A / B, 8164A / B and 8166A / B hosts single-slot plug-in module, which can be for single-channel and DWDM test applications to provide a flexible, cost-effective incentives. The module S + C band wavelength coverage of up to 110 nm. Characteristics: high optical output power: +13 dBm wide tuning range: 1465 nm to 1575 nm, built-in wavelength meter can provide high accuracy: + /-20pm built-coherent control of stimulated Brillouin scattering suppression advantages of optical amplifier test required excitation power, do not need to add a drive amplifier. With a wide tuning range of 110 nm in a single scan of the adjacent bands on the S + C DUT characterization of the built-in wavelength meter can be avoided using an external wavelength monitoring, thereby reducing the measurement uncertainty. Built-in the coherent control functions to avoid interference effects arising problems and excess cavity test nonlinear effects in optical fiber transmission link of stimulated Brillouin scattering (SBS)
