Sikholelwa ukuba abasebenzisi abaninzi banokuqonda okuthile kwee-transceivers optical.Abasebenzisi abaninzi abazi kakhulu malunga neemodyuli zamehlo.Iimodyuli ze-Optical ziyinxalenye ebalulekileyo yee-transceivers optical.Iimodyuli ze-Optical zibaluleke kakhulu kwii-transceivers optical, ngoko yintoni imodyuli ye-optical kwaye kutheni inokudlala indima enkulu kwii-transceivers optical?

Imodyuli ye-optical ye-transceiver optical isetyenziswa ngokubanzi kwi-backbone network ye-fiber optical network.Iimodyuli ze-Optical zihlulwe ikakhulu kwi-GBIC, SFP, SFP +, XFP, SFF, CFP, njl., kunye neentlobo ze-optical interface ziquka i-SC kunye ne-LC.Nangona kunjalo, i-SFP, i-SFP +, i-XFP isetyenziswa ngokuqhelekileyo namhlanje endaweni ye-GBIC.Isizathu kukuba i-GBIC inkulu kwaye yophuka ngokulula.Nangona kunjalo, i-SFP esetyenziswa ngokuqhelekileyo incinci kwaye iphantsi.Ngokohlobo, lunokwahlula kwiimodyuli ze-optical mode enye kunye neemodyuli ze-optical modes ezininzi.Iimodyuli ze-optical mode enye zifanelekile ukuhanjiswa komgama omde;iimodyuli ze-optical mode ezininzi zifanelekile ukuhanjiswa kwexesha elifutshane.

Izixhobo ze-Optical ziphuhlisa ngokubhekiselele kwi-miniaturization, ukuphucula (umbane / optical, optical / ukuguqulwa kombane) ukusebenza kakuhle, kunye nokuphucula ukuthembeka;I-teknoloji ye-planar optical waveguide (PLC) iya kunciphisa ngakumbi umthamo we-bidirectional / ezintathu-directional optical components kunye nokuphucula ukuthembeka kwecandelo.Imisebenzi kunye nokusebenza kwee-chips zesekethe ezidibeneyo zomeleziwe, ukwenzela ukuba umthamo weemodyuli ze-optical uncitshiswe kwaye ukusebenza kuye kwaphuculwa ngokuqhubekayo.Inkqubo ngokuqhubekayo ibeka iimfuno ezintsha zemisebenzi eyongezelelweyo yemodyuli, kwaye umsebenzi ohlakaniphile wemodyuli ye-optical kufuneka uphuculwe ngokuqhubekayo ukuhlangabezana neemfuno zenkqubo.

Enyanisweni, kwi-transceiver optical, ukubaluleka kwemodyuli ye-optical idlula kakhulu i-chip core chip.Imodyuli ye-optical yenziwe ngezixhobo ze-optoelectronic, iisekethe ezisebenzayo kunye ne-optical interfaces.Ukubeka nje, indima yemodyuli ye-optical kukuguqulwa kwe-photoelectric.Isiphelo sokudlulisa siguqula imiqondiso yombane kwimiqondiso ye-optical.Emva kokudluliselwa nge-fiber optical, isiphelo esifumanayo siguqula izibonakaliso ze-optical zibe iimpawu zombane, ezisebenza kakuhle kwaye zikhuselekile kunama-transceivers.Emva kokuba amandla evuliwe, imodyuli ye-optical ikwinkqubo yokukhanya rhoqo, kwaye kuya kubakho ukuthotywa kwexesha.Ke ngoko, kubaluleke kakhulu ukufumanisa umsebenzi wemodyuli ye-optical.

Kufuneka sisebenzise imitha yamandla okubona umgangatho wemodyuli ye-optical.Ngokubanzi, xa imodyuli ye-optical ishiya umzi-mveliso, umenzi wokuqala uya kungenisa ingxelo yokuhlola umgangatho wale batch kumenzi wokucubungula.Umvelisi usebenzisa imitha yamandla okukhanya kuvavanyo lwangempela., Xa umahluko ungaphakathi koluhlu lokunika ingxelo, luyimveliso efanelekileyo.

Ngexabiso elivavanyiweyo ngemodyuli ye-optical, uluhlu lwamandla efektri yi-3 ~ 8dBm.Ngokuthelekisa amanani, imodyuli ye-optical inokumiselwa njengemveliso efanelekileyo.Ikhunjuzwa ngokukodwa ukuba ixabiso elincinci lamandla, libuthathaka amandla okunxibelelana okubonakalayo;oko kukuthi, imodyuli ye-optical yamandla aphantsi ayikwazi ukwenza ukuhanjiswa kwexesha elide.Ngokutsho kwemithombo echaphazelekayo kwishishini, ezinye iiworkshops ezincinci ziza kuthenga iimodyuli ze-second-hand optical, ezinamanani azo ahlaziywayo kwaye asetyenziswe kwizixhobo zokuhambisa i-optical transmission.Ngokucacileyo, oku kukungakhathali kakhulu kubasebenzisi.
