3:20 Upto 10Gbps-40Gbps, Direct modulation (Intensity modulation) can be used at transmitter side and Direct Detection at receiver side. But for Higher rate we use EO modulators

Ho fatto una stupida scoperta nel 1977 da bambino 12 enne, da un semplice (chiodo) OA85 un diodo a baffo di gatto al (anodo) tungsteno e germanio saldato sul reoforo con lo stagno che è il catodo, che alimentandolo a 9V inversamente si è illuminato come una lampadina da 75 W, tutto racchiuso da un cilindro in vetro, al confronto dei LED del 1962 si mostravano pallidi fatti con silicio drogato con arsenico e gallio e contatti e substratto in argento o oro e ora in alluminio che fa da specchio e la capsula fa da lente plastica anti riciclo, la cosa divertente :( e che nel 2010 gli scienziati scoprano il silicio e germanio drogati di stagno si illumina meglio e si fanno pure i migliori LASER a diodi a semiconduttori e si abbattono pure costi e inquinamento, fatta presente questa bella notizia del 1977 ben 44 anni dopo, non sanno che rispondere se hai la laurea al Faggin o al Oliver Twist.
