Xa kuziwa ekuhanjisweni kwexesha elide, ngokuqwalasela iindleko, umqhubi omdala uya kuqala ukucinga ngezinto ezimbini: i-fiber optic transceivers kunye namabhuloho.Ngefiber optics, sebenzisa ii-transceivers.Ukuba akukho fiber optical, kuxhomekeke ekubeni indawo eyiyo inokuxhuma kwibhulorho.
Ngaphezu kweekhilomitha ezilishumi kunye neekhilomitha ezininzi, kodwa kunye nokuqinisekisa ukuhanjiswa okuzinzile nokuthembekileyo, i-fiber optical ibalulekile.
Namhlanje, masithethe ngesisombululo esikhokelayo kunxibelelwano lwefiber optical-fiber transceiver.
I-transceiver sisixhobo sokuguqula umqondiso, esidla ngokubizwa ngokuba yi-fiber optic transceiver.Ukuvela kwee-transceivers ze-fiber optical ziguqula izibonakaliso zombane ezijijekileyo kunye neempawu zombane omnye komnye, ziqinisekisa ukuhanjiswa okugudileyo kweepakethi zedatha phakathi kweenethiwekhi ezimbini, kwaye kwangaxeshanye ukwandiswa komda wokuhambisa umgama womnatha ukusuka kwi-100 yeemitha zeengcingo zobhedu ukuya kwi-100. iikhilomitha (ifiber yemowudi enye).
Ngophuhliso oluqhubekayo lwetekhnoloji, iye yaba yindlela yangoku yokuba itekhnoloji ye-VO ye-serial enesantya esiphezulu ithatha indawo yetekhnoloji ye-I/O yesiqhelo.Isantya sojongano lwebhasi olukhawulezayo yi-133 MB/s ye-ATA7.Izinga lokudlulisa elinikezelwa yi-SATA1.0 inkcazo ekhutshwe kwi-2003 ifikelele kwi-150 MB / s, kwaye isantya sethiyori ye-SATA3.0 sifikelele kwi-600 MB / s.Xa isixhobo sisebenza ngesantya esiphezulu, ibhasi enxuseneyo isengozini yokuphazamiseka kunye ne-crosstalk, nto leyo eyenza ukuba i-wiring ibe nzima kakhulu.Ukusetyenziswa kwee-transceivers ze-serial kunokwenza lula uyilo loyilo kunye nokunciphisa inani lezixhumi.Ujongano lothotho lukwasebenzisa amandla amancinci kunezibuko ezinxuseneyo kunye nebhanwidth yebhasi efanayo.Kwaye imo yokusebenza yesixhobo itshintshiwe ukusuka kwi-parallel transmission ukuya kwi-serial transmission, kwaye isantya se-serial sinokuphindwa kabini njengoko ukwanda kwamanani.
I-FPGA-based based embedded level level ye-Gb kunye ne-low-power-architecture benefits, yenza abaqulunqi basebenzise izixhobo ezisebenzayo ze-EDA ukusombulula ngokukhawuleza ingxaki yeprotocol kunye nokutshintsha kwesantya.Ngokusetyenziswa ngokubanzi kweFPGA, i-transceiver ihlanganiswe kwi-FPGA, eye yaba yindlela efanelekileyo yokusombulula ingxaki yesantya sokuhanjiswa kwezixhobo.
Ii-transceivers ze-high-speed-speed transceivers zenza ukuba kube lula ukuhambisa inani elikhulu ledatha-point-to-point.Le teknoloji yonxibelelwano lwe-serial isebenzisa ngokupheleleyo umthamo wejelo lendawo yothumelo kwaye inciphisa inani lamajelo osasazo afunekayo kunye nezikhonkwane zesixhobo xa kuthelekiswa neebhasi zedatha ezihambelanayo, ngaloo ndlela kunciphisa kakhulu unxibelelwano.iindleko.I-transceiver enentsebenzo egqwesileyo kufuneka ibe neenzuzo zokusetyenziswa kwamandla aphantsi, ubungakanani obuncinci, ukucwangciswa okulula, kunye nokusebenza okuphezulu, ukwenzela ukuba kube lula ukudibanisa kwinkqubo yebhasi.Kwi-high-speed serial data transmission protocol, ukusebenza kwe-transceiver kudlala indima ecacileyo kwisantya sokuhanjiswa kwe-interface yebhasi, kwaye kuchaphazela nokusebenza kwenkqubo ye-interface yebhasi ukuya kwinqanaba elithile.Olu phando luhlalutya ukufezekiswa kwemodyuli ye-transceiver yesantya esiphezulu kwi-platform ye-FPGA, kwaye inika isalathiso esiluncedo ekufezekiseni iiprothokholi ze-serial ezikhawulezayo.
Le bhokisi incinci inezinga eliphezulu kakhulu lokuvezwa kwiskimu sothumelo lomgama omde, kwaye inokubonwa rhoqo ekubekeni iliso kwethu, i-wireless, ukufikelela kwifiber optical kunye nezinye iimeko.
kusetyenziswa kwanjani
Ii-transceivers ze-fiber optical zisetyenziswa ngokubanzi ngababini, kwaye zisetyenziswe ekupheleni kokufikelela (ezinokuthi zixhunywe kwii-terminals ezifana neekhamera, ii-APs, kunye nee-PC ngokutshintsha) kunye nesiphelo sokufumana kude (njengegumbi lekhompyutha / igumbi lokulawula eliphakathi, njl. ., ngokuqinisekileyo, ingasetyenziselwa ukufikelela kwi-terminal), ngaloo ndlela yakha ibhulorho yonxibelelwano ephantsi, enesantya esiphezulu kunye nezinzile kuzo zombini iziphelo.
Ngokomgaqo, okoko nje iinkcukacha zobugcisa ezinje ngesantya, ubude bamaza, uhlobo lwefayibha (ezifana nemveliso enye yefayibha enye, okanye enye imowudi enye yefayibha ezimbini) ziyangqinelana, iibrendi ezahlukeneyo ziyadityaniswa, kwaye isiphelo esinye se-fiber transceiver kunye nesinye isiphelo semodyuli ye-optical inokuphunyezwa.unxibelelwano.Kodwa asiyicebisi.
IFayibha enye kunye neDual
I-transceiver ye-fiber enye ithatha iteknoloji ye-WDM (i-wavelength division multiplexing) iteknoloji, enye isiphelo sihambisa i-wavelength 1550nm, ifumana i-wavelength 1310nm, kwaye enye isiphelo idlulisela i-1310nm kwaye ifumana i-1550nm, ukuze iqonde ukufumana idatha kunye nokuthumela kwi-fiber optical enye.
Ngoko ke, kukho i-port ye-optical enye kuphela kolu hlobo lwe-transceiver, kwaye iziphelo ezimbini zifana ngqo.Ukuze ukwahlula, iimveliso zichongwa ngokubanzi ngeephelo ze-A kunye ne-B.
I-fiber transceiver enye (kumfanekiso iperi, zero enye)
Izibuko ze-optical ze-transceiver ye-dual-fiber "zimbini" - i-port yokudlulisa ephawulwe nge-TX + i-port efunyenweyo ephawulwe nge-RX, enye isiphelo sisibini, kwaye ngamnye ukuthumela kunye nokwamkela benza imisebenzi yabo.Ubude be-TX kunye ne-RX buyafana, zombini ziyi-1310nm.
I-transceiver enefayibha ezimbini (umfanekiso yiperi, zero enye)
Okwangoku, iimveliso ze-fiber enye eziphambili kwimarike.Kwimeko yamandla othumelo athelekisekayo, ii-transceivers zefayibha enye “ezigcina iindleko zefiber enye” ngokucacileyo zithandwa kakhulu.
Imowudi enye kunye ne-Multimode
Umahluko phakathi kwe-fiber transceivers ye-fiber optical-mode kunye ne-multi-mode optical fiber transceivers ilula, oko kukuthi, umahluko phakathi kwe-fiber optical fiber kunye ne-multi-mode optical fiber.
I-core diameter ye-fiber-mode-mode incinci (indlela enye yokukhanya ivumelekile ukuba isasazeke), ukusabalalisa kuncinci, kwaye kuchasene nokuphazamiseka.Umgama wothumelo uphezulu kakhulu kunolo lwefayibha ezininzi, ezinokufikelela ngaphezu kweekhilomitha ezingama-20 okanye namakhulu eekhilomitha.Idla ngokusetyenziswa kwiikhilomitha ezi-2.
Kungenxa yokuba i-diameter engundoqo ye-fiber yemodi enye incinci, umqadi kunzima ukulawula, kwaye i-laser enexabiso eliphezulu iyafuneka njengomthombo wokukhanya (i-multi-mode fiber ngokubanzi isebenzisa umthombo wokukhanya we-LED), ngoko ke ixabiso iphezulu kunaleyo yefayibha ezininzi, eneendleko eziphezulu.
Okwangoku, kukho iimveliso ezininzi ze-transceiver zendlela enye kwimarike.Izicelo zeziko ledatha ye-multi-mode zingaphezulu, izixhobo ezingundoqo kwizixhobo eziphambili, unxibelelwano olufutshane lwe-bandwidth enkulu.
iiparameters ezintathu eziphambili
1. Isantya.Kukho iimveliso ezikhawulezayo kunye neGigabit ezikhoyo.
2. Umgama wothumelo.Kukho iimveliso zeekhilomitha ezininzi kunye neekhilomitha ezininzi.Ukongeza kumgama phakathi kweziphelo ezimbini (umgama wentambo ye-optical), ungalibali ukujonga umgama ukusuka kwi-port yombane ukuya kwi-switch.Imfutshane ingcono.
3. Uhlobo lwemowudi yefiber.Imowudi enye okanye iimowudi ezininzi, i-single-fiber okanye i-multi-fiber.
