Difference between Amplifier and Repeater
1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain.
2. Repeater has an amplifier as a part of it.
3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.

What is the difference between passive star and active repeater in fiber network?
A passive star has no electronics. The light from one fiber illuminates a number of others. An active repeater converts the optical signal to an electri- cal one for further processing.

What is the difference between a dvd player and a optical dvd player?
The difference between optical and non optical is the way the drive in the DVD reads the disk. Optical is a better and more higher quality reader. So the picture is much better.

What is photonic networks?
A photonic (or optical) network is a communications network in which information is transmitted entirely in the form of optical or infrared transmission(IR) signals. In atrue photonic network, every switch and every repeater works with IR or visible-lightenergy. A recent development in this field is the erbium amplifier. Conversion toand from electrical impulses is not done except at the source and destination (origin andend point).
What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
What is the difference between optical and electron microscope?
The electron microscope is stronger than the optical microscope Electron microscope use electrons not light waves
What is the difference between portable media and optical media?
Portable means easy to carry round, Optical means uses light to make it work. So optical media could be portable.
