What are the needs of light sources for fibre optic communication?

Light sources for fibre optic communication should meet certain given requirements as illustrated below:

a. Monochromatic (to ignore chromatic dispersion)

b. Intense (transmission is probable for longer distances)

c. Capable of being simply modulated (for illustration by using LED and LD, modulation can be done simply unlike into gas ionization lamps and other kinds of lasers)

d. Small and compact (to couple fibres simply and effectively)

e. Durable and cheap
