(I-Small Form-factor Pluggable) I-transceiver encane exhuma embobeni ye-SFP yokushintsha kwenethiwekhi futhi ixhume ku-Fiber Channel ne-Gigabit Ethernet (GbE) izintambo zefibre optical ngakolunye uhlangothi. Esikhundleni se-transceiver ye-GBIC, amamojula e-SFP abizwa nangokuthi "i-mini-GBIC" ngenxa yobukhulu bawo obuncane. Ngokukhetha i-module ye-SFP efanelekile, imbobo kagesi efanayo ekushintsheni ingaxhuma kumafayili ezinhlobo ezahlukene (i-multimode noma i-singlemode) kanye namaza ahlukene. Uma i-fiber ithuthukisiwe, imodyuli ye-SFP ithathelwa indawo.

I-SFP iguqula amasiginali kagesi we-serial abe amasignali e-serial optical futhi ngokuphambene nalokho. Amamojula e-SFP ayashintshashintsha futhi aqukethe i-ID kanye nolwazi lwesistimu lokushintshwa.

I-Combo SFP Ports

Izimbobo ze-Combo zibhangqwe nezimbobo ze-Ethernet. Isibonelo, uma i-transceiver ye-SFP ixhunywe kumbobo 24 ye-SFP, khona-ke imbobo ye-Ethernet 24 iyacishwa ngisho noma ikhebuli ixhunyiwe.

I-XFP ne-SFP+ yama-Gigabits angu-10

Okukhulu kune-SFP, ama-transceivers e-XFP ayengawokuqala ukuphatha imigqa ye-optical ye-Gigabit Ethernet engu-10, ngoba i-SFP isekela kuphela kufika ku-4.25 Gbps. Usayizi wemojula ofanayo njenge-SFP, i-SFP+ yethulwa kamuva ukuze isingathe i-10 Gbps kodwa idinga ukujikeleza okwengeziwe kudivayisi yomsingathi. Ngenxa yalokho, izimbobo ze-SFP+ zitholakala kakhulu kumakhadi we-plug-in wamaseva namaswishi ebhizinisi. Bona i-transceiver ne-GBIC.

Ikusasa lezokuxhumana lenzeka namuhla ngendlela yefiber optics. Abaningi be-ISP nabahlinzeki bezokuxhumana bazama ngokushesha ukusebenzisa i-fiber optics ukungena, noma esikhundleni samanethiwekhi abo akhona.

Ubuchwepheshe be-JHA sebuvele bunabo lobu buchwepheshe obukhona, futhi ngenxa yalokho bunamanethiwekhi athuthuke kakhulu eYurophu nase-US.

Inzuzo enkulu kakhulu ye-fiber optics amandla ayo okugcina umkhawulokudonsa we-symetrical wamahhala nokuqina. Izintambo ze-fiber optic zingahambisa inani elikhulu kakhulu ledatha ngokuphumelelayo kunezintambo zethusi ezivamile.

Izintambo ze-fiber optic zenziwe ngemicu emincane yengilazi futhi zidlulisela idatha ngama-pulses of light, aguqulwa abe amasignali kagesi. Njengoba ukukhanya kuhamba ngokushesha kunogesi, idatha ihamba ngokushesha kakhulu kunezinye izinhlobo zekhebula.

Njengoba izintambo ze-fiber optic zenziwe ngengilazi hhayi zensimbi, aziwuhambisi ugesi ngakho-ke azikhathazwa ukuphazamiseka kukagesi okonakalisayo okuvela emithonjeni yamandla, izinto zikagesi noma izibani.

Amakhasimende ethu ahlomula ekusebenzeni kwenethiwekhi yethu okungenakuqhathaniswa kanye nezixazululo ezihlanganisiwe ezihambisanayo zeVoice|Internet|data.

Ukubambisana ne-JHA kuqinisekisa ukuthi uzokwazi ukunikela isikhathi esiningi ekukhuliseni ibhizinisi lakho kanye nesikhathi esincane sokukhathazeka ngokusebenza kwenethiwekhi yakho.

Ncoma izixazululo ze-Metro Ethernet

Uma inethiwekhi yakho ihlanganisa izindawo eziningi, amahhovisi akude, amahhovisi asekhaya nanoma iyiphi inhlanganisela yokuxhumana kwebhizinisi nebhizinisi, i-Metro Ethernet ingagcina ithrafikhi yenethiwekhi yakho iphephile futhi, okubaluleke kakhulu, ivikelekile.

I-JHA ingahlinzeka ibhizinisi lakho ngesixazululo sangokwezifiso esivumela amabhizinisi amasayithi amaningi esikhungweni sedatha ukuthi afinyelele inethiwekhi yangasese esebenzisa enye yezingosi zawo ezixhunyiwe.

Kukhona nesinye isixazululo se-P2P Connection (I-Point-to-Point Connections for Data and Voice).
