He aha ka EDFA Amplifier?

ʻO EDFA (Erbium-doped Fiber Amplifier), i hana mua ʻia ma 1987 no ka hoʻohana ʻana i ka ʻoihana, ʻo ia ka mea hoʻonui optical i hoʻopili ʻia ma ka ʻōnaehana DWDM e hoʻohana ana i ka fiber Erbium-doped e like me ka mea hoʻonui optical e hoʻonui pololei i nā hōʻailona.Hāʻawi ia i ka hoʻonui koke ʻana i nā hōʻailona me nā lōʻihi hawewe he nui, ma loko o ʻelua mau kaha.ʻO kekahi ka Conventional, a i ʻole C-band, ma kahi o 1525 nm a 1565 nm, a ʻo kekahi ʻo ka Long, a i ʻole L-band, ma kahi o 1570 nm a 1610 nm.Eia nō naʻe, ʻelua mau puʻupuʻu maʻamau i hoʻohana ʻia, 980 nm a me 1480 nm.ʻO ka band 980nm kahi ʻāpana absorption kiʻekiʻe i hoʻohana pinepine ʻia i ka noi haʻahaʻa haʻahaʻa, ʻoiai ʻo 1480nm band he haʻahaʻa haʻahaʻa akā ʻoi aku ka laulā absorption cross-section i hoʻohana mau ʻia no nā mea hoʻonui mana kiʻekiʻe.

Hōʻike kikoʻī ke kiʻi ma lalo nei pehea e hoʻonui ai ka amplifier EDFA i nā hōʻailona.Ke hana nei ka amplifier EDFA, hāʻawi ia i ka laser pump me 980 nm a i ʻole 1480 nm.Ke hele ka laser pump a me nā hōʻailona hoʻokomo i ka hui, e hoʻonui ʻia lākou ma luna o ka fiber Erbium-doped.Ma o ka launa pū ʻana me nā iona doping, hiki ke hoʻokō ʻia ka hoʻonui ʻana i ka hōʻailona.ʻAʻole hoʻohaʻahaʻa loa kēia amplifier āpau āpau i ke kumukūʻai akā hoʻomaikaʻi nui i ka pono no ka hoʻonui ʻana i ka hōʻailona optical.I ka pōkole, ʻo ka EDFA amplifier kahi mea nui i ka mōʻaukala o ka fiber optics hiki ke hoʻonui pololei i nā hōʻailona me nā lōʻihi hawewe he nui ma luna o hoʻokahi fiber, ma kahi o ka hoʻonui ʻana i ka hōʻailona optical-electrical-optical.

Hāʻawi ʻo Rofea Optoelectronics i kahi laina huahana o nā modulators electro-optic kalepa, modulators phase, photodetectors, nā kumu kukui laser, dfb lasers, optical amplifier, EDFAs, SLD laser, QPSK modulation, pulse laser, light detector, balance photodetector, Semiconductor laser, laser driver , ka mea hoʻohui fiber, ka laser puʻupuʻu, ka mea hoʻonui fiber optic, ka mika mana opu, ka laser broadband, ka laser Tunable, ka hoʻopaneʻe optic optic modulator, ka mea ʻike maka, ka mea hoʻokele laser diode, ka fiber amplifier, ka erbium doped fiber amplifier, ke kumu kukui laser, ka laser kumu kukui.Hāʻawi pū mākou i nā modulators kūikawā no ka hana maʻamau, e like me 1 * 4 array phase modulators, ultra-low Vpi, a me ultra-high extinction ratio modulators, i hoʻohana mua ʻia i nā kulanui a me nā kula. nā bandwidth electro-optic a hiki i 40 GHz me ka hoʻokomo haʻahaʻa Loss, haʻahaʻa Vp, kiʻekiʻe PER.He kūpono no nā noi like ʻole mai nā loulou RF analog i nā kamaʻilio wikiwiki.
