Incazelo

+ Okungaxhunywa Kwe-Small Form-Factor (SFP)iyifomethi yemojuli yesixhumi senethiwekhi encane, evuleka kalula esetshenziswa kokubili izinhlelo zokusebenza zokuxhumana ngocingo kanye nokuxhumana kwedatha.

I-interface ye-SFP kuhadiwe yokuxhumana iyisikhala se-modular se-transceiver ethile yemidiya, njengekhebula le-fiber-optic noma ikhebula lethusi.

+ QSFP, emele i-Quad Small Form-factor Pluggable,uhlobo lwemojuli ye-transceiver esetshenziselwa ukudlulisa idatha ngesivinini esikhulu kumadivayisi okuxhumana, ikakhulukazi ezikhungweni zedatha nasezindaweni zokubala ezisebenza kahle kakhulu.

Yenzelwe ukusekela iziteshi eziningi (ngokuvamile ezine) futhi ingaphatha amazinga edatha asukela ku-10 Gbps kuya ku-400 Gbps, kuye ngohlobo oluthile lwemodyuli.

Incazelo Ejwayelekile

I-OP-QSFP+-01zenzelwe ukusetshenziswa kuma-gigabit angu-40 ngomzuzwana phezu kwefayibha yemodi ye-multimode.

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

Ingxenye ye-transmitter ye-optical ifaka i-VCSEL eneziteshi ezine (i-Vertical Cavity).

I-Surface Emitting Laser) array, i-buffer yokufaka eneziteshi ezine kanye nomshayeli we-laser, iziqaphi zokuxilonga, amabhlogo okulawula kanye nokwehlukanisa. Kokulawula imodyuli, isikhombimsebenzisi sokulawula sifaka isikhombimsebenzisi se-Two Wire Serial sewashi kanye nezimpawu zedatha. Iziqaphi zokuxilonga ze-VCSEL bias, izinga lokushisa lemodyuli, amandla okukhanya adluliselwe，Amandla okukhanya atholiwe kanye ne-voltage yokunikezela iyasetshenziswa futhi imiphumela iyatholakala ngesibonisi se-TWS. Imingcele ye-alamu kanye nesexwayiso imiselwe izimfanelo eziqashwe. Amafulegi ayasethwa futhi kukhiqizwe ukuphazamiseka lapho izimfanelo zingaphandle kwemingcele. Amafulegi ayasethwa futhi kukhiqizwe ukuphazamiseka kokulahlekelwa yisignali yokufaka (i-LOS) kanye nezimo zephutha lokudlulisela. Wonke amafulegi ayavalwa futhi azohlala ebekwe ngisho noma isimo esiqala isivalo siphela futhi ukusebenza kuyaqhubeka. Zonke iziphazamiso zingavalwa futhi amafulegi asethwe kabusha ngokufunda irejista efanele yefulegi. Ukukhishwa kwe-optical kuzoncibilikisa ukulahlekelwa kwesignali yokufaka ngaphandle kokuthi i-squelch ikhutshaziwe. Ukutholwa kwephutha noma ukuvalwa kwesiteshi ngesibonisi se-TWS kuzokhubaza isiteshi. Isimo, i-alamu/isexwayiso kanye nolwazi lwephutha luyatholakala ngesibonisi se-TWS.

Ingxenye yokwamukela okubonakalayo ye-transceiver ifaka i-photodiode array ye-PIN yeziteshi ezine, i-TIA array yeziteshi ezine, i-buffer yokuphuma kweziteshi ezine, iziqaphi zokuxilonga, kanye namabhulokhi okulawula nokwehlukanisa. Iziqaphi zokuxilonga zamandla okufaka okubonakalayo ziyasetshenziswa futhi imiphumela iyatholakala nge-interface ye-TWS. Imingcele ye-alamu kanye nesexwayiso isungulwe yezimfanelo eziqashwe. Amafulegi ayasethwa futhi kuphazanyiswe lapho izimfanelo zingaphandle kwemingcele. Amafulegi ayasethwa futhi kuphazanyiswe ukulahleka kwesignali yokufaka okubonakalayo (i-LOS). Wonke amafulegi ayavalwa futhi azohlala esethiwe noma ngabe isimo esiqala ifulegi siphela futhi ukusebenza kuyaqhubeka. Zonke iziphazamiso zingavalwa futhi amafulegi aphinde asethwe kabusha lapho kufundwa irejista efanele yefulegi. Ukuphuma kukagesi kuzoncipha ukulahleka kwesignali yokufaka (ngaphandle kokuthi i-squelch ikhutshaziwe) kanye nokucishwa kwesiteshi nge-interface ye-TWS. Isimo kanye nolwazi lwe-alamu/isexwayiso luyatholakala nge-interface ye-TWS.

Izici Eziyinhloko ze-QSFP

+ Ubuningi Obuphezulu:Amamojula e-QSFP aklanyelwe ukuba abe mancane, okuvumela inani elikhulu lokuxhumeka endaweni encane kakhulu.

+ Okungaxhunywa Kakhulu:Zingafakwa futhi zikhishwe kudivayisi ngenkathi ivuliwe, ngaphandle kokubangela ukuphazamiseka kunethiwekhi.

+ Iziteshi Eziningi:Amamojula e-QSFP ngokuvamile aneziteshi ezine, ngayinye ekwazi ukudlulisa idatha, okuvumela amazinga aphezulu e-bandwidth kanye nedatha.

+ Amanani Edatha Ahlukahlukene:Kunezinhlobo ezahlukene ze-QSFP, njenge-QSFP+, QSFP28, QSFP56, kanye ne-QSFP-DD, ezisekela isivinini esihlukile kusukela ku-40Gbps kuya ku-400Gbps nangaphezulu.

+ Izicelo Ezihlukahlukene:Amamojula e-QSFP asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ukuxhumana kwesikhungo sedatha, ukubalwa kwekhompyutha okusebenzayo okuphezulu, kanye namanethiwekhi okuxhumana ngocingo.
