Isebenza njani imodyuli ye-fiber transceiver ye-SFP?

1. Yintoni imodyuli ye-transceiver?

Iimodyuli zeTransceiver, njengoko igama libonisa, zimbini, kwaye i-SFP yenye yazo.Igama elithi "transceiver" yindibaniselwano ye "transmitter" kunye "receiver".Ke ngoko, inokusebenza njenge-transmitter kunye nomamkeli ukuseka unxibelelwano phakathi kwezixhobo ezahlukeneyo.Ihambelana nemodyuli yinto ebizwa ngokuba yisiphelo, apho imodyuli ye-transceiver inokufakwa khona.Iimodyuli ze-SFP ziya kuchazwa ngokubanzi kwizahluko ezilandelayo.
1.1 Yintoni i-SFP?

I-SFP imfutshane kwiFom-Factor plugable encinci.I-SFP yimodyuli ye-transceiver esemgangathweni.Iimodyuli ze-SFP zinokubonelela ngesantya se-Gbit/s sokuqhagamshelwa kweenethiwekhi kunye nenkxaso ye-multimode kunye ne-singlemode fibers.Olona didi luqhelekileyo lwe-interface yi-LC.Ngokubonakalayo, iintlobo zefiber ezixhamlayo ziyakwazi ukuchongwa ngombala we-SFP's pull tab, njengoko kuboniswe kuMzobo B. I-blue pull ring ngokuqhelekileyo ithetha i-cable-mode-mode, kunye ne-ring ring ithetha i-multi-mode cable.Kukho iintlobo ezintathu zeemodyuli ze-SFP ezihlelwe ngokwesantya sokuhambisa: SFP, SFP +, SFP28.
1.2 Yintoni umahluko phakathi kwe-QSFP?

I-QSFP imele "i-Quad Form-Factor Pluggable".I-QSFP inokubamba amajelo amane ahlukeneyo.Njenge-SFP, zombini imodi enye kunye ne-multi-mode fibers inokudibaniswa.Ijelo ngalinye linokudlulisa amaxabiso edatha ukuya kuthi ga kwi-1.25 Gbit/s.Ngoko ke, ireyithi yedatha iyonke inokufikelela kwi-4.3 Gbit / s.Xa usebenzisa iimodyuli ze-QSFP +, iziteshi ezine nazo zinokudityaniswa.Ngoko ke, izinga ledatha lingafikelela kwi-40 Gbit / s.
