Amazinga ahlobene nemboni yezokuxhumana ngokubona ikakhulukazi avela ezinhlanganweni ezifana ne-IEEE, ITU, kanye ne-MSA Industry Alliance.Kunamazinga amaningi amamojula we-100G.Amakhasimende angakhetha uhlobo lwemojuli olungabizi kakhulu ngokuya ngezimo ezihlukene zohlelo lokusebenza.Kuzinhlelo zokusebenza zebanga elifushane phakathi kwama-300m, i-multimode fiber kanye namalaser e-VCSEL asetshenziswa kakhulu, futhi ekudluliseni okungu-500m-40km, i-fibre yemodi eyodwa, i-DFB noma amalaser e-EML asetshenziswa kakhulu.
Uma kuqhathaniswa ne-2.5G, i-10G noma i-40G ye-wavelength division transmission systems, i-100G optical transmission isebenzisa izamukeli ezihambisanayo zedijithali ukuze kumephu zonke izakhiwo ze-optical signal esizindeni sikagesi ngokusebenzisa ukuhlukahluka kwesigaba nokuhlukahluka kwe-polarization, futhi isebenzisa ubuchwepheshe obuvuthiwe bokucubungula isignali yedijithali esizindeni sikagesi. .Isizinda sisebenzisa i-polarization demultiplexing, isinxephezelo sokulinganisa ngokonakala kwesiteshi, ukutholwa kwesikhathi, isilinganiso sesigaba senkampani yenethiwekhi, ukulinganiswa kwezimpawu kanye nokuqoshwa komugqa.Ngenkathi iqaphela ukudluliswa kwe-100G optical, uchungechunge lwezinguquko ezinkulu zezobuchwepheshe zenzeke kumamojula we-100G optical, kuhlanganise nobuchwepheshe be-modulation yesigaba se-polarization multiplexing, ubuchwepheshe bokwamukela okuhambisanayo kwedijithali, ubuchwepheshe bokubhala ikhodi bokulungisa iphutha besizukulwane sesithathu, njll, ngaleyo ndlela ukwanelisa izidingo zabasebenzisi. kanye nesikhathi.Izidingo eziqhubekayo.
Amaphakheji ajwayelekile we-100G amamojula optical ikakhulukazi ahlanganisa i-CXP, i-CFP, i-CFP2, i-CFP4, i-CFP8, ne-QSFP28.Ngokuthuthuka eminyakeni yamuva nje, ukuthunyelwa kwemikhiqizo yochungechunge lwe-CFP kuye kwancipha kancane kancane, futhi iphakheji ye-QSFP28 inqobe ukunqoba okuphelele ngenxa yobukhulu bayo obuncane kanye nokusetshenziswa kwamandla aphansi, futhi iningi lamaphakheji asanda kuvela e-200G kanye ne-400G nawo asebenzisa i-QSFP- DD amaphakheji.Njengamanje, izinkampani eziningi ze-optical module zinemikhiqizo yochungechunge lwe-100G kuphakheji ye-QSFP28 emakethe.
1.1 100G QSFP28 module optical
I-QSFP28 optical module inomqondo wokuklama ofanayo njengemojula ye-QSFP optical.Ku-QSFP28, isiteshi ngasinye singathumela futhi samukele idatha efika ku-28Gbps.Uma kuqhathaniswa namamojula we-CFP4 optical, amamojula e-QSFP28 optical mancane ngosayizi kunamamojula optical CFP4.I-module ye-QSFP28 ye-optical inenzuzo yobuningi ngaphezu kwe-CFP4 module optical, futhi ukusetshenziswa kwamandla ngesikhathi sokusebenza ngokuvamile akudluli i-3.5W, kuyilapho ukusetshenziswa kwamandla kwamanye amamojula optical ngokuvamile phakathi kwe-6W ne-24W.Kusukela kulo mbono, ukusetshenziswa kwamandla kuphansi kakhulu kunamanye amamojula we-100G optical.
1.2 100G CXP imojuli yokubona
Izinga lokudlulisela le-CXP optical module liphezulu njengo-12*10Gbps, futhi lisekela ukuxhuma okushisayo.U-“C” umele u-12 nge-hexadecimal, futhi inombolo yesiRoman “X” imele ukuthi isiteshi ngasinye sinezinga lokudlulisela elingu-10Gbps.U-“P” ubhekisela ku-plugable esekela ukuxhuma okushisayo.I-CFP optical module ihloselwe kakhulu emakethe yekhompyutha enesivinini esikhulu, futhi iyisengezo se-CFP optical module esikhungweni sedatha ye-Ethernet.Ngobuchwepheshe, amamojula e-CFP optical asetshenziswa kanye nemicu ye-multimode optical yokudlulisa idatha ebangeni elifushane.Ngenxa yokuthi imakethe ye-multimode fibre idinga amaphaneli aminyana kakhulu, usayizi awukakalungiselelwanga ngempela imakethe ye-multimode fiber.
I-CXP optical module ingu-45mm ubude no-27mm ububanzi, futhi incane kune-XFP optical module ne-CFP optical module, ngakho-ke inganikeza isixhumi esibonakalayo senethiwekhi ephakeme kakhulu.Ukwengeza, i-CXP optical module iyisistimu yokuxhuma yethusi ecaciswe yi-Wireless Broadband Trade Association, engasekela i-12 10GbE ye-10GbE, i-3 10G yokudlulisa isixhumanisi seziteshi ze-40GbE noma i-12 10G Ethernet Fiber Channel noma i-wireless 12 * QDR ukudluliswa kwesixhumanisi se-broadband. izimpawu.
1.3 100G CFP/CFP2/CFP4 module optical
I-CFP Multi-Source Agreement (MSA) ichaza izidingo ukuthi amamojula optical ashintshashintshayo angasetshenziswa ku-40G kanye ne-100G yokudlulisa inethiwekhi, kuhlanganise nesizukulwane esilandelayo se-high-speed Ethernet (40GbE ne-100GbE).I-CFP optical module isekela ukudluliswa kwe-fiber yemodi eyodwa kanye nemodi eminingi ngamanani ahlukahlukene, izivumelwano kanye nobude besixhumanisi, kufaka phakathi zonke izixhumanisi ezincike kumidiya (PMD) ezifakwe ku-IEEE 802.3ba ejwayelekile, futhi inethiwekhi ye-100G iqukethe ama-PMD amathathu: 100GBASE -SR10 ingadlulisela i-100m, i-100GBASE-LR4 ingadlulisela u-10KM, futhi i-100GBASE-ER4 ingadlulisela u-40KM.
I-CFP optical module iklanyelwe ngesisekelo se-interface encane ye-pluggable optical module (SFP), kodwa inkulu ngobukhulu futhi isekela ukudluliswa kwedatha ye-100Gbps.I-interface kagesi esetshenziswa i-CFP optical module isebenzisa iziteshi ze-10 * 10Gbps zokudlulisela ohlangothini ngalunye (RX, TX), ngakho-ke isekela ukuguqulwa okuhlangene kwe-10 * 10Gbps ne-4 * 25Gbps.I-CFP optical module ingasekela isignali eyodwa ye-100G, i-OTU4, isignali ye-40G, i-OTU3 noma i-STM-256 / OC-768.
Nakuba i-CFP optical module ingakwazi ukubona izinhlelo zokusebenza zedatha ye-100G, ngenxa yobukhulu bayo obukhulu, ayikwazi ukuhlangabezana nezidingo zezikhungo zedatha ephezulu.Kulokhu, ikomidi le-CFP-MSA lichaze amanye amafomu amabili: CFP2 kanye ne-CFP4 amamojula optical.
