Niki Amplifier ya EDFA？

EDFA (Erbium-Dope Fibre Amplifier), yahimbwe bwa mbere mu 1987 kugirango ikoreshwe mu bucuruzi, niyo ikoreshwa cyane ya optique amplifier muri sisitemu ya DWDM ikoresha fibre ya Erbium ikoreshwa nka optique ya amplification optique kugirango izamure neza ibimenyetso.Ifasha guhita yongerera ibimenyetso ibimenyetso bifite uburebure bwinshi, cyane mubice bibiri.Imwe ni Ibisanzwe, cyangwa C-band, hafi ya 1525 nm kugeza 1565 nm, indi ni Long, cyangwa L-band, hafi ya 1570 nm kugeza 1610 nm.Hagati aho, ifite ibice bibiri bikunze gukoreshwa kuvoma, 980 nm na 1480 nm.Itsinda rya 980nm rifite igice kinini cyo kwinjiza igice gisanzwe gikoreshwa mugukoresha urusaku ruke, mugihe 1480nm band ifite igice cyo hasi ariko cyagutse cyo kwinjizamo igice gikunze gukoreshwa mubyongerewe imbaraga.

Igishushanyo gikurikira kirerekana neza uburyo amplifier ya EDFA yongera ibimenyetso.Iyo amplifier ya EDFA ikora, itanga pompe laser ifite 980 nm cyangwa 1480 nm.Iyo pompe laser hamwe nibimenyetso byinjira byanyuze kuri kupler, bizagwiza hejuru ya fibre ya Erbium.Binyuze mu mikoranire na doping ion, ibimenyetso byongera ibimenyetso birashobora kugerwaho amaherezo.Ibi byose-optique amplifier ntabwo igabanya cyane ikiguzi ahubwo izamura cyane imikorere ya optique ya signal optique.Muri make, amplifier ya EDFA nintambwe yibanze mumateka ya fibre optique ishobora kongera ibimenyetso byerekana uburebure bwumurongo mwinshi hejuru ya fibre imwe, aho kuba optique-amashanyarazi-optique yerekana ibimenyetso.

Rofea Optoelectronics itanga umurongo wibicuruzwa byubucuruzi bwa electro-optique yubucuruzi, modulatrice yicyiciro, fotodetekeri, isoko yumucyo wa lazeri, laseri ya dfb, amplificateur optique, EDFAs, SLD laser, QPSK modulation, pulse laser, detector yumucyo, fotodetector yuzuye, laser ya shoferi .Dutanga kandi modulator nyinshi zihariye zo kwihindura, nka 1 * 4 moderi ya moderi ya moderi, ultra-low Vpi, hamwe na moderi ya ultra-high extinction ratio modulator, ikoreshwa cyane cyane muri za kaminuza n'ibigo. Bafite uburebure bwumurambararo wa 780 nm kugeza 2000 nm hamwe na amashanyarazi ya electro-optique agera kuri 40 GHz hamwe no kwinjiza bike Gutakaza, Vp yo hasi, PER ndende.Birakwiriye kubikorwa bitandukanye biva muri analog RF ihuza itumanaho ryihuse.
