二手HP 83438A 寬帶光源資料：
The Agilent 83438A provides more than +6 dBm in the 1550 nm window, allowing you to characterize advanced components such as isolators, circulators, add/drop multiplexers, gratings, or demultiplexers for dense wavelength-division multiplexing （DWDM） systems.
The Agilent 83438A Erbium ASE source emits amplified spontaneous emission （ASE） from an Erbium doped fiber. Such light is one hundred times stronger than an EELED, and ten thousand times stronger than a white light source. This makes it an ideal source for characterizing components with high losses （such as crosstalk or isolation）. A pump laser activates the fluorescence of the Erbium doped fiber. The modulation input allows on/off control or modulation up to 300 Hz for applications using lock-in techniques. An optical isolator （standard in each instrument） protects the active fiber from backreflections from the device under test, which significantly improves the stability.
Features
- High power density allows high measurement range
- Single-mode fiber output, angled connector option
- Unpolarized （standard） or fully polarized （optional） to characterize the polarization dependence versus wavelength of the device under test
- Modulation input: up to 300Hz for applications using lock-in techniques or external control （on/off）
