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.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
