Ngokutsho kovavanyo, imodyuli ye-Gigabit SFP optical inokusebenza kwi-10 Gigabit SFP + port, kodwa i-10 Gigabit SFP + imodyuli ye-optical ayikwazi ukusebenza kwi-port ye-Gigabit SFP. Xa imodyuli ye-Gigabit SFP ye-optical ifakwe kwi-10 Gigabit SFP + port, isantya sale port yi-1G, kungekhona i-10G. Ngamanye amaxesha eli zibuko liya kuvalwa ngesantya se-1G de ulayishe kwakhonatshintshaokanye ukhuphe imiyalelo ethile. Ngoko kwiimeko ezininzi, imodyuli ye-SFP ye-optical inokufakwa kwi-SFP + port.
Ukongeza, i-SFP + izibuko ngokubanzi azixhasi isantya esingaphantsi kwe-1G. Oko kukuthi, asikwazi ukufaka imodyuli ye-100BASE SFP ebonakalayo kwi-SFP + port. Enyanisweni, kule ngxaki, kuxhomekeke kakhulu kwiTshintsha Tshintshaimodeli. Amanye amachweba e-SFP + anokuxhasa i-SFP, amanye ayenzi. Umzekelo, phantse zonke SFP + izibuko zonke Cisco CISCOiiswitshixhasa iimodyuli ze-SFP ezibonakalayo, kunye ne-SFP ezininzi + namachweba e-Brocadeiiswitshiinkxaso kuphela SFP +. Nangona isoloko inokwenzeka, kukhuselekile ukulandela ulwazi olunikezwe yiTshintshaumthengisi.
I-10G SFP + ayikwazi ukuhambelana ngokuzenzekelayo kunye neemodyuli ze-optical Gigabit SFP
Kwiimeko ezininzi, sinokusebenzisa iimodyuli ze-SFP optical kwi-SFP + port, kodwa oku akuthethi ukuba iimodyuli ze-SFP ezibonakalayo ezifakwe kwi-SFP + izibuko zinokuxhasa i-1G. Kwikhonkco ye-fiber optical, ukuba sidibanisa imodyuli ye-SFP ye-optical kunye ne-SFP + imodyuli ye-optical, isenokungasebenzi kakuhle! Kule ngxaki, ukuba usebenzisa i-SFP + intambo yesantya esiphezulu, ayikwazi ukungahambisani neGigabit SFP.
I-SFP kunye ne-SFP + iimodyuli ze-optical ezisetyenziswa kwi-cabling yenethiwekhi kunye nedatha yokwakhiwa kwegumbi lekhompyutha kufuneka ziqinisekise isantya esifanayo kuzo zombini iziphelo zekhonkco yefiber. Ngokomzekelo, i-SFP + port kwelinye icala isebenzisa i-10G SFP + 1310nm 10KM LC DDM imodyuli ye-optical, kwaye enye isiphelo isebenzisa imodyuli efanayo ye-optical. Iimodyuli zefiber enye kufuneka zidityaniswe .
I-SFP ifayibha enye yokuhanjiswa kwemodyuli yobude bobude:
① Tx1310 / Rx1550nm, Tx1550 / Rx1310nm;
② Tx1490 / Rx1550nm, Tx1550 / Rx1490nm.
I-SFP + imodyuli enye yefiber optical transmission wavelength:
① Tx1270 / Rx1330nm, Tx1330 / Rx1270nm
② Tx1490 / Rx1550nm, Tx1550 / Rx1490nm).
