Keysight (Agilent) 81662A DFB Laser Source Module

The Agilent 81662A Distributed Feedback (DFB) Laser Source module provides +10dBm output power to overcome the power penalties given in todays test setups. It's excellent stability in power and wavelength is key for accurate testing of any kind of optical amplifiers, such as EDFA, TDFA, semiconductor and Raman amplifiers. Specifications. Maximum output: Typical > +10 dBm (10 mW). CW stability (24 hours): Typical ±0.03 dB. Wavelength (original model): ITU Grid (100 GHz) ie: 1,529.55 nm (opt. 309); 1,610.06 nm (opt. 505) or Center wavelength: (opt. 131) 1310 nm ± 5 nm, (opt. 149) 1490 nm ± 3 nm, (opt. 151) 1510 nm ± 3 nm, (opt. 155) 1550 nm ± 3 nm, (opt. 162) 1625 nm ± 3 nm. Tuning range: Typical > ± 500 pm. Display resolution: 10 pm. Repeatability: ± 3 pm (typical ± 1 pm). Stability (15 minutes): ± 3 pm (typical ± 1 pm). Fiber type: Panda PMF 9 / 125 µm. Output connector: Compatible to angled contact APC, ASC, DIN47256/4108. Side mode suppression ratio (SMSR): Typical 45 dB. Internal digital modulation mode: Free selection 200 Hz to 100 kHz, all output signals are pulse shaped duty cycle 50%. Internal coherence control for linewidth broadening. Tuning speed over full range 30 s.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
