I-CFP MSA ngumgangatho wokuqala kushishino wokuxhasa ii-transceivers ze-optical ze-40 kunye ne-100Gbe Ethernet. I-CFP multi-source protocol kukuchaza iinkcukacha zokupakisha kwiimodyuli ze-optical ezitshintshwayo ezishushu ukukhuthaza usetyenziso lwe-40 kunye ne-100Gbit/s, kubandakanya usetyenziso lwe-Ethernet olukhawulezayo lwesizukulwana esilandelayo (40 kunye ne-100GbE). Iintlobo zeephakheji zeemodyuli ze-optical ze-100G CFP series yi-CFP, CFP2, kunye ne-CFP4.
Intshayelelo ye-CFP/CFP2/CFP4 Optical Module
Ubungakanani be-CFP optical module yeyona inkulu, i-CFP2 optical module yisiqingatha se-CFP, i-CFP4 optical module yi-CFP enye kwisine, kwaye isitayile sephakheji ye-QSFP28 optical module sincinci kuneso se-CFP4 optical module. Umthamo wezi modyuli zintathu, Njengoko kubonisiwe ngezantsi. Okufuneka kukhunjuzwe kukuba ii-CFP/CFP2/CFP4 optical modules azinakusetyenziswa ngokutshintshana, kodwa zingasetyenziswa ngaxeshanye kwinkqubo enye.
Iimodyuli ze-CFP optical zixhasa ukuhanjiswa kwi-single-mode kunye ne-multi-mode optical fibers ezinezantya ezininzi, iiprotokholi, kunye nobude beekhonkco njengoko kufuneka, kuquka zonke ii-interfaces ze-physical medium-related (PMD) eziqukwe kumgangatho we-IEEE802.3ba.
Imodyuli ye-CFP optical yenzelwe ngokusekelwe kwi-interface ye-small pluggable optical module (SFP), enobukhulu obukhulu kunye nokudluliselwa kwedatha ye-100 Gbps. Imodyuli ye-CFP optical inokuxhasa isignali enye ye-100G, i-OTU4, isignali enye okanye ezingaphezulu ze-40G, i-OTU3 okanye i-STM-256/OC-768.
I-100G CFP2 idla ngokusetyenziswa njengekhonkco lonxibelelwano lwe-100G Ethernet, enokusebenza kakuhle kokudlulisa kuneemodyuli ze-CFP optical, kwaye ubukhulu bayo obuncinci buyenza ifaneleke kwiintambo eziphezulu.
Imodyuli ye-optical ye-100G CFP4 inesantya esifanayo nemodyuli ye-optical ye-CFP/CFP2. Ukusebenza kakuhle kokudluliselwa kuphuculwe kakhulu, kodwa ukusetyenziswa kwamandla kuncitshisiwe, kwaye iindleko ziphantsi kune-CFP2. Ke ngoko, imodyuli ye-optical ye-CFP4 ineenzuzo ezingenakutshintshwa. Thetha ngeenzuzo zeemodyuli ze-optical ze-CFP4.
Iingenelo ze-CFP4 optical module
1. Ukusebenza kakuhle kothumelo: Imodyuli yokuqala ye-100G CFP optical ifumene izinga lothumelo lwe-100G ukuya kwi-10G channels, ngelixa imodyuli yangoku ye-100G CFP4 optical ifikelela kwi-100G transmission ngokusebenzisa iitshaneli ezine ze-25G, ngoko ke ukusebenza kakuhle kothumelo kuphezulu. Uzinzo luqina ngakumbi.
2. Umthamo omncinci: Umthamo we-CFP4 optical module yi-1/4 ye-CFP, eyi-module encinci ye-optical kuthotho lwee-CFP zee-optical modules.
3. Ukuhlanganiswa kweemodyuli eziphezulu: Inqanaba lokuhlanganiswa kwe-CFP2 liphindwe kabini kunele-CFP, kwaye inqanaba lokuhlanganiswa kwe-CFP4 liphindwe kane kunele-CFP.
4. Ukusetyenziswa kwamandla okuphantsi kunye neendleko: Ukusebenza kakuhle kokudluliselwa kweemodyuli ze-optical ze-CFP4 kuphuculwe kakhulu, kodwa ukusetyenziswa kwamandla kuncitshisiwe, kwaye iindleko zenkqubo nazo ziphantsi kuneze-CFP2.
Isishwankathelo
Imodyuli ye-optical yesizukulwana sokuqala ye-100G yayiyimodyuli enkulu kakhulu ye-CFP optical, kwaza kwavela iimodyuli ze-optical ze-CFP2 kunye ne-CFP4. Phakathi kwazo, imodyuli ye-optical ye-CFP4 sisizukulwana samva nje seemodyuli ze-optical ze-100G, kwaye ububanzi bayo yi-1/4 kuphela yemodyuli ye-optical ye-CFP. Indlela yokupakisha yemodyuli ye-optical ye-QSFP28 incinci kuneyemodyuli ye-optical ye-CFP4, oko kuthetha ukuba imodyuli ye-optical ye-QSFP28 inoxinano olukhulu lwe-port kwiswitshi.
Nangona imodyuli ye-QSFP28 optical ineenzuzo ezininzi, yenye nje yezisombululo ezininzi zeenethiwekhi ze-100G. Kwizicelo ezithile ezifana namaziko edatha kunye namagumbi okutshintsha, ukukhetha esifanelekileyo sesona sisombululo silungileyo.
I-HUANET ibonelela ngeentlobo ngeentlobo ze-100G CFP/CFP2/CFP4 kunye ne-100G QSFP28 ezikumgangatho ophezulu kunye nokuhambelana okuhle ngexabiso eliphantsi.
