I-About Erbium
I-erbium yintsimbi emhlophe emhlophe, ethambileyo, esebenzisa i-salts enemibala eluhlaza okwesibhakabhaka. I-erbium-doped fiber amplifiers (EDFAs) ikhuthaza iimpawu ezibonakalayo ngaphandle kokuguqulwa kwe-electric, evumela i-internet yakudala.
Iinkqubo
Ii-fiber optic amplifier (EDFAs), i-metallurgical additive, unyango lwe-laser, kunye ne-pink glass colorant.
Inyathelo 1:
I-erbium-doped fiber amplifier yimisonto ye-internet, ikhuthaza iimpawu zesibane ezidlula emantla elwandle.
