+ I-Cisco QSFP-100G-SR4-S Ehambisanayo QSFP28 Optical Transceiver Module yakhelwe ukusetshenziswa ku-100GBASE Ethernet throughput kufika ku-100m phezu kwe-OM4 multimode fiber (MMF) kusetshenziswa ubude begagasi obungu-850nm ngesixhumi se-MTP/MPO-12. Le transceiver ihambisana ne-IEEE 802.3bm 100GBASE-SR4 kanye ne-CAUI-4 ejwayelekile. Imisebenzi yokuxilongwa kwedijithali nayo iyatholakala ngesixhumi esibonakalayo se-I2C, njengoba kucaciswe i-QSFP28 MSA, ukuze kuvunyelwe ukufinyelela kumapharamitha okusebenza wesikhathi sangempela. Ngalezi zici, le transceiver efakwa kalula, eshintshashintshayo eshisayo ifaneleka ukusetshenziswa ezinhlelweni ezihlukahlukene, njengezikhungo zedatha, amanethiwekhi ekhompyutha asebenza kahle kakhulu, umgogodla webhizinisi kanye nezinhlelo zokusebenza zesendlalelo sokusabalalisa.

Incazelo Ejwayelekile

I-OP-QSFP28-01 yakhelwe ukusetshenziswa ku-100 Gigabit ngomzuzwana izixhumanisi phezu kwe-multi mode fiber.

Zihambisana ne-QSFP28 MSA kanye ne-IEEE 802.3bm. Ingxenye ye-optical transmitter ye-transceiver ihlanganisa i-4-channel VCSEL (Vertical Cavity Surface Emitting Laser), i-4-channel input buffer kanye nomshayeli we-laser, iziqapha zokuxilonga, amabhulokhi okulawula kanye nokuchema. Ngokulawulwa kwemojula, isixhumi esibonakalayo sokulawula sihlanganisa i-Two Wire Serial interface yewashi namasignali edatha. Iziqaphi zokuxilonga ze

Ukuchema kwe-VCSEL, izinga lokushisa lemojula, amandla optical adlulisiwe, amandla optical atholiwe kanye ne-voltage yokunikezela kuyasetshenziswa futhi imiphumela iyatholakala nge-interface ye-TWS. I-alamu kanye nemikhawulo yesexwayiso isungulelwa izibaluli ezigadwayo. Amafulegi asethwa futhi iziphazamiso zikhiqizwa uma i-

izimfanelo zingaphandle kwemingcele. Amafulegi nawo ayasethwa futhi kube neziphazamiso ezidalelwa ukulahlekelwa isignali yokokufaka

(LOS) kanye nezimo zephutha zokudlulisela. 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.
