CFP/CFP2/CFP4 Optical Modyuli

I-CFP MSA ngumgangatho wokuqala wemboni yokuxhasa i-40 kunye ne-100Gbe i-Ethernet transceivers optical.I-protocol ye-CFP yemithombo emininzi kukuchaza inkcazo yokupakisha kwiimodyuli ze-hot-swappable optical ukukhuthaza izicelo ze-40 kunye ne-100Gbit / s, kubandakanywa izicelo ze-Ethernet zesizukulwana esilandelayo (40 kunye ne-100GbE).Iindidi zephakheji ze-100G CFP iimodyuli ze-optical series ziyi-CFP, i-CFP2, kunye ne-CFP4.

Ukuqaliswa kweCFP/CFP2/CFP4 Optical Module

Ubungakanani bemodyuli ye-CFP ye-optical yeyona nkulu, imodyuli ye-CFP2 ye-optical isiqingatha se-CFP, i-module ye-CFP4 ye-optical module enye yesine ye-CFP, kunye nesitayela sephakheji ye-QSFP28 imodyuli ye-optical incinci kuneyo. Imodyuli yeCFP4 yokubona.Umthamo wezi modyuli zintathu, Njengoko kubonisiwe ngezantsi.Yintoni ekufuneka ikhunjulwe kukuba iimodyuli ze-CFP / CFP2 / CFP4 ze-optical azikwazi ukusetyenziswa ngokungafaniyo, kodwa zingasetyenziswa ngexesha elifanayo kwinkqubo efanayo.

Iimodyuli ze-CFP ze-optical zixhasa ukuhanjiswa kwimodi enye kunye ne-multi-mode optical fibers enezantya ezininzi, iiprothokholi, kunye nobude bekhonkco njengoko kufunwa, kubandakanywa zonke ii-interfaces ezinxulumene nomzimba (PMD) ezibandakanyiweyo kumgangatho we-IEEE802.3ba.

Imodyuli ye-CFP ye-optical yenzelwe ngesiseko se-interface encinci ye-pluggable optical (SFP), kunye nobukhulu obukhulu kunye nokuxhasa ukuhanjiswa kwedatha ye-100 Gbps.Imodyuli ye-CFP ye-optical inokuxhasa uphawu olulodwa lwe-100G, i-OTU4, enye okanye ngaphezulu kweempawu ze-40G, i-OTU3 okanye i-STM-256 / OC-768.

I-100G CFP2 isoloko isetyenziswa njengekhonkco ye-100G Ethernet yokudibanisa, kunye nokusebenza okuphezulu kokuhanjiswa kuneemodyuli ze-CFP optical, kunye nobukhulu bayo obuncinci buyenza ifaneleke kwi-wiring ephezulu.

I-100G CFP4 imodyuli ye-optical inesantya esifanayo ne-CFP / CFP2 imodyuli ye-optical.Ukusebenza kokuhanjiswa kuphuculwe kakhulu, kodwa ukusetyenziswa kwamandla kuyancitshiswa, kwaye iindleko ziphantsi kuneCFP2.Ngoko ke, imodyuli ye-CFP4 ye-optical ineenzuzo ezingenakubuyiselwa.Thetha malunga neenzuzo ze-CFP4 iimodyuli ze-optical.

Izinto ezilungileyo zeCFP4 imodyuli ye-optical

1. Ukuhanjiswa okuphezulu okuphezulu: Imodyuli yokuqala ye-100G CFP iphumelele izinga lokudluliselwa kwe-100G ngokusebenzisa iziteshi ze-10 ze-10G, ngelixa imodyuli yangoku ye-100G CFP4 iphumelele ukuhanjiswa kwe-100G ngokusebenzisa iziteshi ze-4 ze-25G, ngoko ke ukuhanjiswa kuphezulu.Uzinzo lunamandla.

2. Umthamo omncinci: Umthamo we-CFP4 imodyuli ye-optical enye yesine ye-CFP, eyona modyuli encinci ye-optical kwi-series ye-CFP yeemodyuli ze-optical.

3. Ukuhlanganiswa kwemodyuli ephezulu: Inqanaba lokudibanisa leCFP2 liphindwe kabini leCFP, kwaye inqanaba lokudibanisa leCFP4 liphindwe kane leCFP.

4. Ukusetyenziswa kwamandla aphantsi kunye neendleko: Ukusebenza kakuhle kokuhanjiswa kwe-CFP4 iimodyuli ze-optical ziphuculwe kakhulu, kodwa ukusetyenziswa kwamandla kuyancipha, kwaye iindleko zenkqubo nazo ziphantsi kuneCFP2.

Isishwankathelo

Isizukulwana sokuqala se-100G imodyuli ye-optical module yayinkulu kakhulu i-CFP imodyuli ye-optical, emva koko i-CFP2 kunye ne-CFP4 iimodyuli ze-optical zavela.Phakathi kwabo, imodyuli ye-CFP4 ye-optical isizukulwana samva nje se-100G iimodyuli ze-optical, kwaye ububanzi bayo buyi-1/4 kuphela ye-CFP imodyuli ye-optical.Indlela yokupakisha ye-QSFP28 imodyuli ye-optical incinci kunemodyuli ye-CFP4 ye-optical, oku kuthetha ukuba imodyuli ye-QSFP28 ye-optical ine-port density ephezulu kwi-switch.

Nangona imodyuli ye-QSFP28 ye-optical ineenzuzo ezininzi, inye kuphela yezisombululo ezininzi ze-100G networks.Kwizicelo ezithile ezifana namaziko edatha kunye namagumbi okutshintsha, ukukhetha okulungileyo kuyisisombululo esihle.

I-HUANET inikezela zonke iintlobo ze-100G CFP / CFP2 / CFP4 kunye ne-100G QSFP28 ezinomgangatho ophezulu kunye nokuhambelana kakuhle kwixabiso eliphantsi.
