Keysight (Agilent) 81650A 1310 nm Fabry Perot Laser Source Module

The Agilent 81650A Standard Source Module (Fabry-Perot Laser) is insensitive to back reflections, and is stabilized for short and long term applications. It is for use with Agilent 8163A/B Lightwave Multimeter, Agilent 8164A/B Lightwave Measurement System, and Agilent 8166A/B Lightwave Multichannel System. Specifications. Center Wavelength: 1310 nm ±15 nm. Fiber type: Single-mode 9/125 µm. Spectral bandwidth (rms): < 3.5 nm. Output Power: >0 dBm. Short term (15 min) CW power stability: <±0.005 dB typically <±0.003 dB with coherence control active. Long term (24 hr) CW power stability: typically <±0.03 dB. To back reflection (RL >=14 dB): Typical ± 0.003 dB. Internal digital modulation mode: 270 Hz, 330 Hz, 1 kHz, 2 kHz and free selection 200 Hz to 10 kHz. All output signals are pulse shaped, duty cycle 50%. Internal coherence control for linewidth broadening.

Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBm
Optical power referenced to 1 millimatt

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
