Incazelo

+ I-Small Form-factor Pluggable (SFP)iyifomethi yemojula yenethiwekhi ehlangene, exhumeke kuxhumeke kuxhumeke kuyo esetshenziswa kukho kokubili izinhlelo zokusebenza zokuxhumana ngocingo nedatha.

Isixhumi esibonakalayo se-SFP kuzingxenyekazi zekhompuyutha zenethiwekhi iyisikhala semodular se-transceiver eqondene nemidiya, njengekhebula le-fiber-optic noma intambo yethusi.

+ I-QSFP, emele i-Quad Small Form-factor Pluggable,luhlobo lwemojula ye-transceiver esetshenziselwa ukudluliswa kwedatha ngesivinini esikhulu kumadivayisi enethiwekhi, ikakhulukazi ezikhungweni zedatha nasezindaweni zekhompyutha ezisebenza kahle kakhulu.

Iklanyelwe ukusekela iziteshi eziningi (ngokuvamile ezine) futhi ingaphatha amanani edatha asukela ku-10 Gbps kuya ku-400 Gbps, kuye ngohlobo lwemojuli ethile.

Incazelo Ejwayelekile

I-OP-QSFP+-01zenzelwe ukusetshenziswa ku-40 Gigabit ngomzuzwana izixhumanisi phezu kwe-multimode fiber.

Zihambisana ne-QSFP+ MSA kanye ne-IEEE 802.3ba 40GBASE-SR4.

Ingxenye ye-optical transmitter ye-transceiver ihlanganisa i-4-channel VCSEL (Vertical Cavity

I-Surface Emitting Laser) amalungu afanayo, ibhafa yokufaka yeziteshi ezi-4 nomshayeli we-laser, iziqapha zokuxilonga, amabhulokhi okulawula kanye nokuchema. Ngokulawulwa kwemojula, isixhumi esibonakalayo sokulawula sihlanganisa i-Two Wire Serial interface yewashi namasignali edatha. Iziqapha zokuxilonga zokuchema kwe-VCSEL, izinga lokushisa lemojula, amandla optical adlulisiwe,amandla okukhanya atholiwe kanye ne-voltage yokunikezela kuyasetshenziswa futhi imiphumela itholakala ngesixhumi esibonakalayo se-TWS. I-alamu kanye nemikhawulo yesexwayiso isungulelwa izibaluli ezigadwayo. Amafulegi ayasethwa futhi iziphazamiso zikhiqizwa uma izibaluli zingaphandle kwemingcele. Amafulegi nawo ayasethwa futhi aphazamiseke akhiqizelwa ukulahlekelwa isignali yokufaka (i-LOS) kanye nezimo zamaphutha zesithumeli. Wonke amafulegi axhunyiwe futhi azohlala emisiwe ngisho noma isimo esivula i-latch siyacisha futhi ukusebenza kuqalwa kabusha. Zonke iziphazamiso zingafihlwa futhi amafulegi asethwe kabusha ngokufunda irejista yefulegi efanelekile. Okukhiphayo okubonakalayo kuzoncinza ukuze kulahlekelwe isignali yokokufaka ngaphandle uma i-squelch ivaliwe. Ukutholwa kwamaphutha noma ukuvalwa kwesiteshi ngesixhumi esibonakalayo se-TWS kuzokhubaza isiteshi. Isimo, i-alamu/isexwayiso nolwazi lwamaphutha kuyatholakala ngesixhumi esibonakalayo se-TWS.

Ingxenye ye-optical receiver ye-transceiver ihlanganisa i-PIN ye-photodiode ye-4-channel ye-4, i-TIA yamashaneli angu-4, i-buffer ephumayo yamashaneli angu-4, iziqapha zokuxilonga, namabhulokhi okulawula nokuchema. Iziqaphi zokuxilonga zamandla okufakwayo asetshenziswayo futhi imiphumela itholakala ngesixhumi esibonakalayo se-TWS. I-alamu kanye nemikhawulo yesexwayiso isungulelwa izibaluli ezigadwayo. Amafulegi ayasethwa futhi iziphazamiso zikhiqizwa uma izibaluli zingaphandle kwemingcele. Amafulegi nawo ayasethwa futhi aphazamiseke akhiqizelwa ukulahlekelwa isignali yokufaka yokubona (LOS). Wonke amafulegi axhunyiwe futhi azohlala emisiwe ngisho noma isimo esivula ifulegi sisulwa futhi umsebenzi uqala kabusha. Zonke iziphazamiso zingafihlwa futhi amafulegi asethwe kabusha lapho kufundwa irejista yefulegi efanele. Okuphumayo kukagesi kuzoncipha ukuze kulahlekelwe isignali yokokufaka (ngaphandle uma i-squelch ikhutshaziwe) kanye nokuyekiswa ukusebenza kwesiteshi ngesixhumi esibonakalayo se-TWS. Isimo nolwazi lwe-alamu/isexwayiso kuyatholakala ngesixhumi esibonakalayo se-TWS.

Izici ezibalulekile ze-QSFP

+ Ukuminyana Okuphezulu:Amamojula e-QSFP enzelwe ukuthi ahlangane, avumele inombolo ephezulu yokuxhumana endaweni encane.

+ Okushisayo Okuxhumekayo:Angafakwa futhi akhishwe kudivayisi ngenkathi ivuliwe, ngaphandle kokubangela ukuphazamiseka kunethiwekhi.

+ Iziteshi Eziningi:Amamojula e-QSFP ngokuvamile aneziteshi ezine, ngayinye ekwazi ukudlulisa idatha, okuvumela umkhawulokudonsa ophezulu namazinga edatha.

+ Amanani Edatha Ahlukahlukene:Kukhona okuhlukile kwe-QSFP, okufana ne-QSFP+, QSFP28, QSFP56, ne-QSFP-DD, esekela izivinini ezihlukene ukusuka ku-40Gbps ukuya ku-400Gbps nangaphezulu.

+ Izicelo Ezihlukahlukene:Amamojula e-QSFP asetshenziswa ezinhlelweni eziningi ezahlukene, okuhlanganisa ukuxhumana kwesikhungo sedatha, ukusebenza kahle kwekhompyutha kwamakhompyutha, namanethiwekhi ezokuxhumana.
