Keysight (Agilent) 81950A 1527-1565 or 1570-1608 nm opt based Tunable Laser Module

The Agilent 81950A compact tunable laser source is step-tunable for setting channel frequencies within any grid in the C- or L-band. With high output power up to +15 dBm, narrow linewidth of 100 kHz, and offset grid fine-tuning capability, the 81950A is a universal source for realistic loading of the latest transmission systems. It is available with C-band or L-band wavelength coverage. It can reach any wavelength point within its specified wavelength range just like all other Agilent tunable lasers. In system loading applications, it may be preferable to grid-tune the laser like system transmitters, simply by changing the channel index. The channel grid is adjustable to standard ITU-T grid spacing like 50 GHz, and to arbitrary grids. Likewise, the zero frequency (base channel) of the chosen grid is adjustable. A 12 GHz fine-tuning range allows de-tuning the frequency. Specifications. Wavelength (frequency) range: 1527.6 nm to 1565.50 nm (Option 210), 1570.01 nm to 1608.76 nm (Option 201).

Wavelength (frequency) stability (typical, over 24 hours): Typical ± 2.5 pm (± 0.3 GHz), 24 hours. Linewidth (typical), SBS suppression off: < 100 kHz. Maximum output power: = +13.5 dBm (typical = +15 dBm). Power stability Typical: ± 0.03 dB over 1 hour. Power flatness: Typical ± 0.2 dB (full wavelength range). Power repeatability: Typical ± 0.08 dB. Side-mode suppression ratio: Typical 50 dB. Relative intensity noise (RIN): Typical -145 dB/Hz (10 MHz to 40 GHz).

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
