Imigangatho enxulumene neshishini lonxibelelwano lwamehlo ikakhulu liphuma kwimibutho efana ne-IEEE, ITU, kunye ne-MSA Industry Alliance.Kukho imigangatho emininzi yeemodyuli ze-100G.Abathengi banokukhetha olona hlobo lwemodyuli olubiza kakhulu ngokweemeko ezahlukeneyo zesicelo.Ukusetyenziswa kwexesha elifutshane ngaphakathi kwe-300m, i-multimode fiber kunye ne-VCSEL lasers zisetyenziswa kakhulu, kunye ne-500m-40km yokuhanjiswa, i-fiber-mode eyodwa, i-DFB okanye i-EML lasers isetyenziswa kakhulu.
Xa kuthelekiswa ne-2.5G, i-10G okanye i-40G i-wavelength division transmission systems, i-100G i-optical transmission isebenzisa i-digital coherent receivers ukwenza imephu zonke iimpawu ze-optical signal kwi-domain yombane ngokusebenzisa ukuhlukahluka kwesigaba kunye ne-polarization diversity, kwaye isebenzisa iteknoloji yokucwangcisa idijithali evuthiweyo kwindawo yombane. .I-domain iphumeza i-polarization demultiplexing, imbuyekezo yokulinganisa ukonakala kweshaneli, ukubuyiswa kwexesha, uqikelelo lwesigaba somthwali, uqikelelo lwesimboli kunye ne-linear decoding.Ngelixa uqaphela ukuhanjiswa kwe-100G optical, uchungechunge lweenguqu ezinkulu zeteknoloji zenzeke kwiimodyuli ze-100G ze-optical, kubandakanywa i-polarization multiplexing phase modulation technology, iteknoloji yokwamkela i-digital coherent, isizukulwana sesithathu se-super error correction coding technology, njl., ngaloo ndlela iyanelisa iimfuno zabasebenzisi. kunye nexesha.Iimfuno eziqhubela phambili.
1. Imodyuli ye-100G ye-optical
Iiphakheji eziqhelekileyo ze-100G iimodyuli ze-optical ikakhulu ziquka i-CXP, i-CFP, i-CFP2, i-CFP4, i-CFP8, kunye ne-QSFP28.Ngophuhliso kwiminyaka yakutshanje, ukuthunyelwa kweemveliso ze-CFP zechungechunge ziye zancipha ngokuthe ngcembe, kwaye iphakheji ye-QSFP28 iphumelele uloyiso olupheleleyo ngenxa yobukhulu bayo obuncinci kunye nokusetyenziswa kwamandla aphantsi, kwaye ininzi ye-200G esanda kuvela kunye ne-400G iiphakheji nazo zisebenzisa i-QSFP- Iiphakheji zeDD.Okwangoku, iinkampani ezininzi zeemodyuli ze-optical zinemveliso ye-100G yeemveliso kwiphakheji ye-QSFP28 kwimarike.
1.1 100G QSFP28 imodyuli ye-optical
Imodyuli ye-QSFP28 ye-optical inengcamango efanayo yoyilo njengemodyuli ye-QSFP optical.Kwi-QSFP28, isiteshi ngasinye sinokuthumela kwaye sifumane idatha ukuya kwi-28Gbps.Xa kuthelekiswa ne-CFP4 iimodyuli ze-optical, i-QSFP28 iimodyuli ze-optical zincinci ngobukhulu kune-CFP4 iimodyuli ze-optical.Imodyuli ye-QSFP28 ye-optical ine-density advantage kwi-CFP4 imodyuli ye-optical, kwaye ukusetyenziswa kwamandla ngexesha lokusebenza ngokuqhelekileyo akudluli kwi-3.5W, ngelixa ukusetyenziswa kwamandla kwezinye iimodyuli ze-optical ngokuqhelekileyo phakathi kwe-6W kunye ne-24W.Ukusuka kulo mbono, ukusetyenziswa kwamandla kuphantsi kakhulu kunezinye iimodyuli ze-100G ezibonakalayo.
1.2 I-100G imodyuli ye-CXP ebonakalayo
Izinga lokudluliselwa kwemodyuli ye-CXP ye-optical iphezulu njenge-12 * 10Gbps, kwaye isekela iplagi eshushu."C" imele i-12 kwi-hexadecimal, kwaye inombolo yamaRoma "X" imele ukuba ishaneli nganye inezinga lokudluliselwa kwe-10Gbps."P" ibhekiselele kwiplagi exhasa iplagi eshushu.Imodyuli yeCXP ye-optical ijolise ikakhulu kwimarike yekhompyutheni yesantya esiphezulu, kwaye iyongezwa kwimodyuli yeCFP optical kwiziko ledatha ye-Ethernet.Ngokobuchwephesha, iimodyuli ze-CFP ze-optical zisetyenziswa kunye ne-multimode optical fibers ukwenzela ukuhanjiswa kwedatha ekude.Ngenxa yokuba imakethi yefayibha yemultimode ifuna iiphaneli ezinoxinano oluphezulu, ubungakanani abuzange bulungiselelwe imarike yefiber yemultimode.
Imodyuli yeCXP ye-optical i-45mm ubude kunye ne-27mm ububanzi, kwaye incinci kunemodyuli ye-XFP ye-optical kunye ne-CFP imodyuli ye-optical, ngoko inokubonelela nge-interface ye-intanethi ye-intanethi.Ukongezelela, imodyuli ye-CXP ye-optical module yinkqubo yokudibanisa yethusi echazwe yi-Wireless Broadband Trade Association, enokuxhasa i-12 10GbE ye-10GbE, i-3 10G ikhonkco yokuhanjiswa kweziteshi ze-40GbE okanye i-12 10G Ethernet Fiber Channel okanye i-wireless 12 * QDR ikhonkco yokuhanjiswa kwe-broadband. iimpawu.
1.3 100G CFP / CFP2 / CFP4 imodyuli ebonakalayo
I-CFP Multi-Source Agreement (MSA) ichaza iimfuno zokuba iimodyuli ze-hot-swappable optical zingasetyenziswa kwi-40G kunye ne-100G yokuhanjiswa kwenethiwekhi, kubandakanywa nesizukulwana esilandelayo se-Ethernet (40GbE kunye ne-100GbE).Imodyuli ye-CFP ye-optical isekela ukuhanjiswa kwimodi enye kunye ne-multi-mode fibers kunye namazinga ahlukeneyo, iiprothokholi kunye nobude bekhonkco, kubandakanywa zonke ii-interfaces ezixhomekeke kwimidiya (PMD) ezifakwe kumgangatho we-IEEE 802.3ba, kwaye inethiwekhi ye-100G iqulethe ezintathu ze-PMD: 100GBASE -SR10 inokudlulisa i-100m, i-100GBASE-LR4 inokudlulisa i-10KM, kwaye i-100GBASE-ER4 inokudlulisa i-40KM.
Imodyuli ye-CFP ye-optical yenzelwe ngesiseko se-interface encinci ye-pluggable optical (SFP), kodwa inkulu ngobukhulu kwaye isekela ukuhanjiswa kwedatha ye-100Gbps.I-interface yombane esetyenziswe yi-CFP imodyuli ye-optical isebenzisa i-10 * 10Gbps iziteshi zokuhambisa kwicala ngalinye (RX, TX), ngoko isekela ukuguqulwa kwe-10 * 10Gbps kunye ne-4 * 25Gbps.Imodyuli ye-CFP ye-optical inokuxhasa uphawu olulodwa lwe-100G, i-OTU4, isibonakaliso se-40G, i-OTU3 okanye i-STM-256 / OC-768.
Nangona imodyuli ye-CFP ye-optical inokuqonda izicelo zedatha ye-100G, ngenxa yobukhulu bayo obukhulu, ayikwazi ukuhlangabezana neemfuno zamaziko eenkcukacha eziphezulu.Kule meko, ikomiti ye-CFP-MSA ichaze ezinye iifom ezimbini: i-CFP2 kunye ne-CFP4 iimodyuli ze-optical.
