Iitransceivers zefiber opticalzisetyenziswa ngokubanzi kwiindawo zothungelwano zokwenyani apho iintambo ze-Ethernet azinakugqunywa kwaye imicu ye-optical kufuneka isetyenziswe ukwandisa umgama wothumelo.Kwangaxeshanye, baye badlala indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber ebonakalayo kuthungelwano lwendawo yemetropolitan kunye nothungelwano lwangaphandle.Indima ye.

I-Fiber optic transceiver classification: ukuhlelwa kwendalo

Imowudi enyei-fiber optical transceiver: umgama wothumelo lweekhilomitha ezingama-20 ukuya kwiikhilomitha ezili-120 ii-Multi-mode optical fiber transceiver: umgama wokuhanjiswa kweekhilomitha ezi-2 ukuya kwiikhilomitha ezi-5 -30db, usebenzisa i-wavelength ye-1310nm;ngelixa amandla okuhambisa i-120km i-fiber optic transceiver ininzi phakathi kwe-5 kunye ne-0dB, kunye nokuqonda okufunyenweyo yi-38dB, kunye ne-wavelength ye-1550nm isetyenziswa.

Ulwahlulo lweFiber optic transceiver: ulwahlulo olufunekayo

I-fiber optical fiber transceiver: idatha efunyenweyo kwaye ithunyelwe ihanjiswa kwifayibha ezimbini.i-fiber optical transceiver: idatha efunyenweyo kwaye ithunyelwe idluliselwe kwi-pair of optical fibers Njengoko igama lithetha, izixhobo ze-fiber enye zinokugcina isiqingatha se-fiber optical, oko kukuthi, ukufumana nokuthumela idatha kwi-fiber optical fiber, efanelekileyo kakhulu kwiindawo. apho izibonelelo zefiber optical ziqinile.Olu hlobo lwemveliso lusebenzisa itekhnoloji yolwahlulo lwe-wavelength multiplexing, kwaye ubude be-wavelength obusetyenziswayo ubukhulu becala yi-1310nm kunye ne-1550nm.Nangona kunjalo, ngenxa yokuba akukho mgangatho udityanisiweyo wezizwe ngezizwe weemveliso ze-fiber-fiber transceiver, kunokubakho ukungahambelani phakathi kweemveliso zabenzi abahlukeneyo xa zidityanisiwe.Ukongeza, ngenxa yokusetyenziswa kwe-wavelength division multiplexing, iimveliso ze-fiber-fiber transceiver ngokubanzi zinophawu lokunciphisa umqondiso omkhulu.

Inqanaba lokusebenza / izinga

I-100M Ethernet i-fiber optic transceiver: ukusebenza kwinqanaba lomzimba 10 / 100M i-adaptive Ethernet fiber optic transceiver: ukusebenza kwi-data link layer Ngokwezinga lokusebenza / izinga, inokwahlulwa ibe yi-10M eyodwa, i-100M i-fiber optic transceivers, i-10/100M. i-fiber optic transceivers eguqukayo, i-1000M i-fiber optic transceivers, kunye ne-10/100/1000 i-adaptive transceivers.Phakathi kwabo, imveliso ye-transceiver eyodwa ye-10M kunye ne-100M isebenza kwinqanaba lomzimba, kunye neemveliso ze-transceiver ezisebenza kulo luhlu lwangaphambili lwedatha kancinci kancinci.Le ndlela yokudlulisa ineenzuzo zesantya sokuthumela ngokukhawuleza, izinga eliphezulu lokungafihli, kunye nokulibaziseka okuphantsi.Ikulungele ukusetyenziswa kwiilinki zezinga elimiselweyo.Ngelo xesha, ekubeni izixhobo ezinjalo azinayo inkqubo yokuxoxisana ngokuzenzekelayo ngaphambi kokunxibelelana okuqhelekileyo, ziyahambelana Ukwenza ngcono ngokwesondo kunye nokuzinza.

I-Fiber optic transceiver classification: ulwahlulo lwesakhiwo

I-Desktop (imele yodwa) i-fiber optic transceiver: izixhobo zomthengi ezizimeleyo: I-Rack-mounted (modular) i-fiber transceiver optical fiber: efakwe kwi-chassis ene-slot elinesithandathu, isebenzisa unikezelo lwamandla oluphakathi Ngokwesakhiwo, inokwahlulwa kwi-desktop (yima). -yedwa) i-fiber optic transceivers kunye ne-rack-mounted fiber optic transceivers.I-desktop optical fibre transceiver ifanelekile kumsebenzisi omnye, njengokuhlangana ne-uplink yokutshintsha okukodwa kwipaseji.I-Rack-mounted (modular) i-fiber optic transceivers ifanelekile ukuhlanganiswa kwabasebenzisi abaninzi.Okwangoku, ezininzi iiracks zasekhaya ziyimveliso ye-slot ye-16, oko kukuthi, ukuya kwi-16 i-fiber optic transceivers enokufakwa kwi-rack.

Ukuhlelwa kwe-Fiber optic transceiver: ukuhlelwa kodidi lolawulo

I-Ethernet ye-fiber optical transceiver engalawulwayo: iplagi kunye nokudlala, seta imowudi yokusebenza yombane ngokusebenzisa i-hardware dial switch Udidi lolawulo lwenethiwekhi I-Ethernet fiber optic transceiver: inkxaso ye-carrier-grade network management

I-Optical fiber transceiver classification: ukuhlelwa kolawulo lwenethiwekhi

Inokwahlulwa ibe yi-fiber optic transceivers engalawulwayo kunye ne-network controlled fiber optic transceivers.Uninzi lwabasebenzisi banethemba lokuba zonke izixhobo ezikunethiwekhi zabo zinokulawulwa ukude.Iimveliso ze-Fiber optic transceiver, ezifana nokutshintsha kunye neerotha, ngokuthe ngcembe zikhula kweli cala.I-fiber optic transceivers ezinokudityaniswa nazo zinokuhlulwa kulawulo lwenethiwekhi ye-ofisi ephakathi kunye nolawulo lomsebenzisi we-terminal network.I-fiber optic transceivers enokuthi ilawulwe yi-ofisi ephakathi ubukhulu becala ziimveliso ezifakwe kwi-rack, kwaye uninzi lwazo lwamkela i-master-slave management structure.Ngakolunye uhlangothi, imodyuli yolawulo lomnatha oyintloko idinga ukuvotela ulwazi lolawulo lwenethiwekhi kwi-rack yayo, kwaye kwelinye icala, kufuneka iqokelele zonke ii-sub-racks zamakhoboka.Ulwazi olukuthungelwano luthi ke ludityaniswe lungeniswe kwiseva yolawulo lwenethiwekhi.Ngokomzekelo, uchungechunge lwe-OL200 lwe-network-managed optical fiber transceiver imveliso enikezelwa yi-Wuhan Fiberhome Networks isekela isakhiwo solawulo lwenethiwekhi ye-1 (master) + 9 (ikhoboka), kwaye inokulawula ukuya kwi-150 i-fiber transceivers optical ngexesha.Ulawulo lwenethiwekhi yecala lomsebenzisi lunokwahlulwa lube ziindlela ezintathu eziphambili: eyokuqala kukuqhuba iprotocol ethile phakathi kweofisi ephakathi kunye nesixhobo somthengi.Iprothokholi inoxanduva lokuthumela ulwazi lobume bomthengi kwi-ofisi esembindini, kwaye i-CPU yesixhobo se-ofisi ephakathi ilawula la mazwe.Ulwazi kwaye ulungenise kwiseva yolawulo lwenethiwekhi;okwesibini kukuba i-transceiver ye-fiber optical yeofisi ephakathi inokubona amandla optical kwi-port optical port, ngoko ke xa kukho ingxaki kwindlela yokukhanya, amandla okukhanya angasetyenziselwa ukugqiba ukuba ingxaki ikwifiber optical okanye ukusilela kwesixhobo somsebenzisi;Okwesithathu kukufaka i-CPU yolawulo oluphambili kwi-fiber transceiver kwicala lomsebenzisi, ukwenzela ukuba inkqubo yolawulo lwenethiwekhi inokubeka iliso kwimo yokusebenza yezixhobo zecala lomsebenzisi kwelinye icala, kwaye inokuqonda ukucwangciswa okude kunye nokuqalisa kwakhona kude.Phakathi kwezi ndlela zintathu zolawulo lomnatha wecala lomxhasi, ezimbini zokuqala zezokubeka iliso kwindawo ekude yezixhobo ze-client-side, ngelixa eyesithathu ilulawulo lokwenyani lwenethiwekhi ekude.Nangona kunjalo, ekubeni indlela yesithathu yongeza i-CPU kwicala lomsebenzisi, ekwanyusa iindleko zezixhobo zecala lomsebenzisi, iindlela ezimbini zokuqala zineenzuzo ezininzi ngokwexabiso.Njengoko abaqhubi bafuna ngakumbi nangakumbi ulawulo lwenethiwekhi yezixhobo, kukholelwa ukuba ulawulo lwenethiwekhi ye-fiber optic transceivers luya kuba lusebenza ngakumbi kwaye lube krelekrele.

I-Fiber optic transceiver classification: ukuhlelwa kombane

I-fiber optic transceiver eyakhelwe ngaphakathi: i-transceiver eyakhelwe-ngaphakathi yokutshintsha umbane ngumbane we-carrier-grade;Unikezelo lwamandla lwangaphandle lwe-fiber optic transceiver: unikezelo lwamandla lwesiguquli sangaphandle lusetyenziswa kakhulu kwizixhobo zasekuhlaleni.

Ukuhlelwa kwe-Fiber optic transceiver: ukuhlelwa kwendlela yokusebenza

Imodi ye-duplex epheleleyo ithetha ukuba xa ukuthunyelwa kunye nokufumana idatha ihlulwe kwaye ihanjiswe ngemigca emibini eyahlukeneyo yothutho, omabini amaqela kunxibelelwano angathumela kwaye afumane ngexesha elifanayo.Imowudi enjalo yothumelo yinkqubo ye-duplex epheleleyo.Kwimo ye-duplex epheleleyo, isiphelo ngasinye senkqubo yonxibelelwano sixhotyiswe nge-transmitter kunye ne-receiver, ngoko idatha inokulawulwa ukuba idluliselwe kumacala omabini ngexesha elinye.Imowudi ye-duplex epheleleyo ayifuni ukutshintsha isalathiso, ngoko akukho kulibaziseka kwexesha okubangelwa kukusebenza kokutshintsha.Imowudi yesiqingatha se-duplex ibhekisa kusetyenziso lwelayini yothumelo efanayo ekufumaneni nasekuthumeleni.Nangona idatha ingadluliselwa kumacala omabini, amaqela amabini awakwazi ukuthumela nokufumana idatha ngexesha elinye.Le mowudi yothumelo yi-half-duplex.Xa imowudi ye-half-duplex yamkelwa, i-transmitter kunye ne-receiver ekupheleni kwenkqubo yonxibelelwano idluliselwe kumgca wonxibelelwano ngokufumana / ukuthumela iswitshi ukutshintsha isalathiso.Ngoko ke, ukulibaziseka kwexesha kuya kwenzeka.
