There are 3 spectrums of light measured in nm nanometers.
There are 2 downstream spectrums and 1 upstream spectrum.
1490 carries voice and data downstrem. 1550 carries video downstream.
1310 carries all upstream. Generally there are acceptable levels at an ONT. This stands for Optical Network Terminal. Fios has its own standards. 1490 should be no lower than -28nm and 1550 should be no lower than -6. You can do more research if you want to get more detailed specs.

Fireworks exploding in the sky and giving off light are an example of an what?
Fireworks exploding in the sky and giving off light are an example of a chemical reaction. The explosion of the fireworks is caused by the rapid release of energy stored in the chemicals, producing heat, light, and sound.
Can any light make a plant grow?
According to what I have researched most light can make a plant grow, it just depends on the wavelength that the light is flowing. Carl Gelenye has done some work with different wave lengths of light for plants growth and found the violet works the best and blue is the worst.
What does chlorophyll do to make plants appear green?
Chlorophyll absorbs light in the red and blue spectrums for photosynthesis, but reflects green light, giving plants their green color. This is due to the molecular structure of chlorophyll which allows it to absorb certain wavelengths of light and reflect others.
How do emission and absorption spectrums tell us about the composition of objects in our universe?
Each chemical element has a specific emission or absorption spectrum.
What do you use to view light spectrums?
A Spectrophotometer
What kind of light does a csi use to find blood?
it's called an ALS alternate light source. it can project light in different wave lengths and spectrums.
What are fiber-optics?
Fiber optics are cables that are used to transmit data at the speed of light. This uis especially popular with Verizon FiOS services. for details on fios go to www.whyisfiosbetter.viviti.com
Tivo works with fios cablecard?
Yes...TivoHD or Series 3 work with Fios Cablecards. You will need 2 Scards or 1 Mcard from Verizon.
Do parrots have colored eyes?
No, they are not. Their vision is 50 times better than humans.
What information can you get from observing stars?
The list - for this Answer - is quite lengthy: in fact everything that we know about Stars and all other celestial entities comes from the spectrums of the observed Light.
Do sights and sounds have infinite number of variations?
Yes and no. Yes in their true nature (ie: detection by machines) and no in our reality (ie:detection by our senses) It depends on how infinite the discerning (cutting up) of each type of frequency is. On the other hand, light and sound do have limited spectrums but those spectrums have inifinite frequency possibilities in between
What is FiOs?
FiOs is a service provided by Verizon and it stands for fiber optics. In other words, it shoots light through tiny lines of glass, mostly used for high-speed communications. For more info and pictures go to www.whyisfiosbetter.viviti.com FiOS=Fiber Optics: High Speed TV, Internet & Communications. As fast as 1000 MBps.(tested)
What are objects that could act like prisms?
Spectrums
How spectroscopy works?
Spectroscopy is basically the study of the spectrums of visible and non-visible light rays. Specifically, it is determining the output of radiation an object has along the spectrum. This is called a wavelength.
Why is the leaf is green?
Because a leaf normally has green pigment in it called chlorophyll. These pigments absorb all the spectrums of the light except for the green spectrum, which is why leafs appear green.
