As long as you insert the CD in the CD drive correctly (usually label-side up), playing a music CD is one of Windows 10 Media Playerâs easiest tasks. Start by pushing the driveâs Eject button, a rarely labelled button that lives next to or on the disc drive on the front of your computer.
Singlemode fiber has a much smaller core, only about 9 microns, so that the light travels in only one ray (mode.) It is used for telephony and CATV with laser sources at 1310 and 1550 nm because it has lower loss and virtually infinite bandwidth.
Multimode optical fibers, which have a core diameter of 50 micrometers and a cladding diameter of 125 micrometers, can carry hundreds of separate light wave signals over shorter distances. This type of fiber is used in urban systems where many signals must be carried to central switching stations for distribution.n a single-mode fiber, the core is smaller, typically 10 micrometers (a micrometer is one-millionth of a meter) in diameter, and the cladding is 100 micrometers in diameter.
