Keysight (Agilent) 83438A Erbium ASE Source

The Agilent 83438A Erbium ASE Source provides incoherent light for characterizing fiber-optic components. Its output is centered at approximately 1550 nm. Because it has a relatively high-power spectral density, you can probe devices with medium or high insertion loss. Its single-mode output originates from the amplified spontaneous emission (ASE) of an Erbium doped fiber amplifier. The power spectral density of the output is up to one hundred times (20 dB) greater than that of edge emitting LEDs (for example, the Agilent 83437A Broadband Light Source) and up to 100,000 times (50 dB) greater than white-light tungsten lamp sources. An internal optical isolator protects the Agilent 83438A from back reflections from the device under test. This greatly improves the power stability of the Agilent 83438A. Specifications. Total output power: +8.1 dBm maximum (6.5 mW), +5.5 dBm minimum (3.5 mW) . Power stability: < ±0.02 dB (15 minutes), < ±0.05 dB (6 hours). Compatible fiber: 9/125 µm, single mode. Spectral density: > –13 dBm [1 nm] (> 50 µW/nm) @ 1530, 1550, 1560 nm. Output return loss: > 30 dB (characteristic). Degree of polarization: < 5%, standard (characteristic). Modulation: Digital (TTL compatible), DC to 300 Hz (characteristic). Options. 009, Built-in polarizer. 011, Diamond HMS-10 fiber-optic input connector interface. 013, DIN 47256 fiber-optic input connector interface. 014, ST fiber-optic input connector interface. 017, SC fiber-optic input connector interface. 022, Angled contact fiber-optic output interface.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
