1. UkwahlulahlulaFirAI-MPlifiers
Zintathu iindidi eziphambili ze-Amplifical Amplifical:
(1) Semicondo Optimial Amplifier (SOA, Semicondcuctor Opticier);
(2) I-fiber i-fiber Amplifies inamachaphaza emihlaba enqabileyo (i-Erbim Er, i-Thulium Tor, iRumidium ye-fiber ye-fiber amibird amibishiers (I-edfa), kunye ne-fiber ye-fiber ye-fiber ye-fiber (i-TDFO) kunye ne-rasedyllium ye-biber amplifiers Amplifiers (PDFA), njl.
. Ukuthelekisa intsebenzo ye-Amplific ye-Amplifical kuboniswa kwitafile
I-Edfa (i-erbium ye-fiber amplifier)
Inkqubo ye-leser yamaxesha amaninzi isenziwa ngokucombulula i-fiber ye-witz enezinto ezinqabileyo zomhlaba (ezinje nge-ND, i-ND, PR, i-PR, i-Temp.) Emva kokubonelela ngengxelo efanelekileyo, kwenziwa i-fiber lare. I-favelength ye-fiber ye-fiber ye-fiber ye-fiber ye-fiber i-1060nm kunye ne-1330NM, kunye nokuphuhliswa kwalo kunye nesicelo silinganiselwe ngenxa yokunxibelelana ne-fiber offic yonxibelelwano kunye nezinye izizathu. Amagqabi okusebenza e-Edfa ne-PDFA anefestile yelahleko esezantsi (i-1550NM) kunye nokusasazwa kwe-zero) kunxibelelwano lwefayili, kwaye isebenza kakuhle kwizicelo ze-SIBI ngokucacileyo. I-Edfa, olona phuculo lwakhawuleza, lube lusebenza.
IPrincho
Isakhiwo esisisiseko se-Edfa siboniswe kumzobo 1 (a), ethatyathwe ikakhulu yi-fiber esebenzayo (i-erbium-fiber esebenzayo (i-erbium-fiber esebenzayo (nge-25,5-10), i-pump yodidi olukhanyisiweyo (i-1480n i-ortical kunye ne-ofisi ye-orical kunye ne-orical ye-ortical kunye ne-ofisi ye-orical kunye ne-orical ye-orical kunye ne-orical ye-ofisi ye-orical. Ukukhanya kwesibonakaliso kunye nokukhanya kwempompo kunokusasaza kwicala elinye (impompo ye-Codirecal), umkhombandlela ogqwesileyo (ukubuyela umva) okanye zombini impompo Xa ukukhanya kwesibonakaliso kunye nokukhanya kwempompo kukho i-erbium fiber ngaxeshanye, ii-IRBIm I-ION zivuya kwinqanaba le-Pump Light, ikhupha imizobo ehambelana nomqondiso. Umzobo 1 (c) yi-Andontaneous ye-Andontaneous Spollinces (Ase) I-Spectrum ene-bandwidth enkulu (ukuya kuthi ga kwi-20 ukuya kwi-20-40nm) kunye ne-1550nm kunye ne-1550nm ngokulandelelana.
Ezona zibonelelo ziphambili ze-Edfa ziyinzuzo enkulu, i-bandwidth enkulu, amandla aphezulu okuphumeza, impompo ephezulu yokufakelwa, kunye nokungakhathali kwendawo yokulinganisa.
2. Iingxaki nge-fiber of Amplifis
Nangona i-Amplifier ye-Amplifier (ngakumbi i-Edfa) ineengenelo ezininzi, ayisiyonto ilungileyo. Ukongeza kwingxolo eyongezelelweyo enciphisa umgibe womqondiso, zikho ezinye iimpazamo, ezinje:
-Ingalinganiyo ye-SpectRum ye-Ampcrium kwi-Amphadwid Bandwidth ichaphazela ukusebenza kwe-Amnelnel ye-Vialnel.
Xa i-Amphailicares ye-AMPLIFIF ikhutshiwe, iziphumo zengxolo ye-ASE, ukusasazeka kweFibrer kunye neziphumo ze-Fiber kuya kuqokelela.
Le micimbi kufuneka ithathelwe ingqalelo kwisicelo kunye noyilo lwenkqubo.
3. Ukusetyenziswa kwe-Amplifier ye-Amplifier kwiNkqubo yoNxibelelwano lweFinocal Fiber
Kwinkqubo yoNxibelelwano lweFinocal fiber,I-fiber of AmplifierIngasetyenziselwa nje kuphela njenge-Amplet Amplifier ye-Amplimicier yokwandisa amandla othumelo, kodwa kwakhona njengentshabalalo yemvakalelo yokuphucula imvakalelo yokuphucula imvakalelo yokuphucula imvakalelo yokuphucula imvakalelo yokuphucula uhambo, ukwandisa umgama odluliselwayo.
Kwiinkqubo zonxibelelwano ezibonakalayo, ezona zinto ziphambili zinciphisa umgama ohambisayo yilahleko kunye nokusasazeka kwefayibha yefayili. Sebenzisa umthombo wokukhanya okukhanyayo, okanye ukusebenza kufutshane ne-zero-distyriozer, impembelelo yokusasazeka kwefibre incinci. Le nkqubo akufuneki yenze ukuphinda igqitywe ngexesha lokubuyiselwa kwexesha Yanele ukuba inyuse ngokuthe ngqo umqondiso we-Amplifical (1R odlulayo). Abaphengululi be-Amplificali banokusetyenziswa kungekuphela nje kwiinkqubo zomde-umgama omde kodwa nakwiinethiwekhi zokuhambisa i-fiphal, ngakumbi kwiinkqubo ze-WDM, ukonyusa amajelo amaninzi ngaxeshanye.
1) Ukusetyenziswa kwe-Amplifies ye-Amplifical kwi-trink fical fical fical
Umzobo 2 ngumzobo ochetyiweyo wesicelo se-Amplifier kwiNkqubo yoNxibelelwano yeFople. . Umzekelo, ukwamkela i-Edfa, inkqubo yothungelwano Umgama we-1.8GG / s unyusa ukusuka kwi-120km ukuya kwi-250km okanye ifikelela kwi-400km. Umzobo 2 (b) - (d) kukusetyenziswa kweenkqubo ze-Amplifical kwiinkqubo ezahlukeneyo zokunxibelelana; Umzobo (b) yimodi ye-3R yendabuko ye-3R. Umzobo (c) yimodi exutywe ye-3R ye-3R ephindaphindiweyo kunye ne-Amplifikhi ye-Amplifical Amplifical; Umzobo 2 (d) yindlela yokudluliselwa kwayo yonke; Kwinkqubo yonxibelelwano lonke, ayibandakanyi ixesha lokuhlala kunye nesekethelele kwakhona, ngoko ke iyimfihlo, kwaye akukho "miqobo ye-elektroniki. Logama nje ukuthumela kunye nezixhobo zokufumana iziphelo zombini zitshintshwa, kulula ukuphucula ukusuka kwinqanaba eliphantsi ukuya kwinqanaba eliphezulu, kwaye i-Amplific ayifuni kutshintshwa.
2) Ukusetyenziswa kwe-Amplifier ye-Amplific kwinethiwekhi yokuhambisa i-ficad
Izibonelelo eziPhakamisayoIkatiUthungelwano). I-Catch ye-Catv ye-Catv yamkela intambo, ekufuneka ikhule kuyo yonke imitha yamakhulu amabini, kwaye iredithi yenkonzo yenethiwekhi imalunga ne-7km. Inethiwekhi ye-fiber ye-fiber ye-fiber isebenzisa i-Amplifiers ye-Amplifical ayinakho ukwandisa kakhulu inani labasebenzisi abasasazekileyo, kodwa kwandise indlela yenethiwekhi. Uphuhliso lwakutsha nje lubonise ukuba ukuhanjiswa kwe-fiber yefibre / i-hybrid (HFC) kutsala amandla okuba bobabini kwaye banokhuphiswano olomeleleyo.
Umzobo 4 ngumzekelo wenethiwekhi yokuhambisa i-fible ye-I-VSB yeendlela ezingama-35 zeTV. Umthombo wokukhanya we-Derimit yi-DFB-ld kunye ne-wavelength ye-1550m kunye negunya le-3.3DBM. Sebenzisa i-EDFA ye-EDFA njenge-Amplimier yokuHanjiswa kwaMandla, amandla ayo okufaka igalelo malunga -6dbm, kwaye amandla ayo okukhupha malunga ne-13dbm. Imvakalelo ye-Optical Ofr -9.2D BM. Emva kwenqanaba le-4 lokusasaza, inani lilonke labasebenzisi lifikelele kwi-4.2 yezigidi, kwaye indlela yenethiwekhi ingaphezulu kwamashumi eekhilomitha. Umyinge we-Signing-to-ingxolo yovavanyo lwalungaphezulu kwe-45db, kwaye i-Edfa ayizange ibangele ukuncitshiswa kwe-CSO.
