It's a fibre optic of the Single Mode variation. It uses light at a wavelength of 1,550 nanometres to carry a particular signal from A to B.
It may be data (most often) but could be video, voice or any of these multiplexed together - making data.
yes this uses a 1300/1550 nm wavelength.
How long is your co-ax???
The GCF is 1550.
620 is 40% of 1550. 1550 is 250% of 620.
350 is about 22.58% of 1550. 1550 is about 443% of 350.
WDM (wavelength division multiplexing)
I'm not sure if your asking for the scientific notation for .1550 or 1550. 1550 in scientific notation is 1.550 x 10-3 .1550 in scientific notation is 1.550 x 101
this is life in 1550!! LOL
postcode 1550
1550 = 1.55 × 103
1550/2000 = 0.775
