Ethetha ngayoIimodyuli ze-SFP ezibonakalayo, sonke siqhelene nayo.I-SFP imele i-SMALL FORM PLUGGABLE (I-Pluggable encinci).Ngenye yeepakethe ezisetyenziswa ngokuqhelekileyo kwiimodyuli ze-optical Gigabit Ethernet kunye nomgangatho woshishino weGigabit Ethernet.Ke, zeziphi iimodyuli eziqhelekileyo ze-SFP ezibonakalayo?Ngoku landelaI-JHA TECHukuyiqonda.

Imodyuli ye-SFP ye-optical i-compact input / output (I / O) idivaysi, esetyenziswa kakhulu kwi-Gigabit Ethernet switch, ii-routers kunye nezinye izixhobo zenethiwekhi, zithobela imigangatho eyahlukeneyo yonxibelelwano njengeFiber Channel (iFiber Channel), iGigabit Ethernet, i-SONET (i-Synchronous Optical Inethiwekhi), njl. Uyakwazi ukuqonda ngokulula i-1G uxhulumaniso lwefiber optical okanye uxhulumaniso lwentambo yobhedu phakathi kwezixhobo zenethiwekhi kwisiseko sesakhiwo senethiwekhi ekhoyo.

Ingqokelela yeemodyuli eziqhelekileyo ze-SFP ezibonakalayo
Ngokweentlobo ezahlukeneyo ze-transmitter kunye ne-receiver, iimodyuli ze-SFP ze-optical zingahlulwa zibe ziindidi ezininzi, kunye nobude babo bokusebenza, ubude bokuhambisa, izicelo ezifanelekileyo, njl.Eli candelo liza kwazisa iimodyuli ezahlukeneyo ze-SFP.

1000BASE-T imodyuli yokubona ye-SFP:Le modyuli ye-SFP ye-optical ithatha i-interface ye-RJ45, kwaye idla ngokusetyenziswa kwizicelo ze-wiring yenethiwekhi yobhedu kunye neCandelo le-5 yeentambo zenethiwekhi.Owona mgama mkhulu wothumelo yi-100m.

Imodyuli ye-1000Base-SX ye-SFP ebonakalayo:I-1000Base-SX SFP imodyuli ye-optical ithatha i-duplex LC interface, ihambelana ne-IEEE 802.3z 1000BASE-SX standard, idla ngokusetyenziswa kwizicelo ezininzi, kunye nomgama wothumelo xa usebenzisa i-fiber ye-50um ye-multi-mode ye-550m, kunye nomgama wokuhambisa xa usebenzisa. I-62.5um ifayibha ye-multimode yi-220m, kwaye umgama wothumelo xa usebenzisa i-laser ephuculweyo ye-50um fiber multimode inokufikelela kwi-1km.

1000BASE-LX/LH SFP imodyuli yokubona:I-1000BASE-LX / LH imodyuli ye-SFP ye-optical ihambelana ne-IEEE 802.3z 1000BASE-LX umgangatho.Ingasetyenziswa kwizicelo zendlela enye okanye kwiimowudi ezininzi.Iyahambelana nefiber ye-single-mode Umgama wokuhanjiswa ungafikelela kwi-10km, kwaye umgama xa usetyenziswa ngefiber multimode yi-550m.Kufuneka kuqatshelwe ukuba xa i-1000BASE-LX / LH SFP imodyuli ye-optical isetyenziswe kunye ne-fiber yendabuko ye-multi-mode, umthumeli kufuneka asebenzise i-jumper yokuguqula imo.

I-1000BASE-EX yemodyuli yokubona ye-SFP:I-1000BASE-EX Imodyuli ye-SFP ye-optical isetyenziswa ngokuqhelekileyo kwizicelo zokuhambisa imowudi enye, kwaye umgama wokuhambisa unokufikelela kwi-40km xa isetyenziswe ngefayibha ye-mode eyodwa.

I-1000BASE-ZX imodyuli yokubona ye-SFP:I-1000BASE-ZX Imodyuli ye-SFP ye-optical iphinda isetyenziswe kwi-long-mode-mode-mode transmission applications, kwaye umgama wokuhambisa unokufikelela kwi-70 km.Ukuba ufuna ukusebenzisa i-1000BASE-ZX SFP iimodyuli ze-optical kwizicelo apho umgama wokuhambisa ungaphantsi kwe-70 km, kufuneka ufake i-optical attenuator kwikhonkco ukukhusela umbane optical optical okonakalisa ukuphela kokufumana imodyuli ye-optical.

1000BASE BIDI SFP imodyuli yokubona:I-1000BASE BIDI Imodyuli ye-SFP ye-optical isebenzisa i-simplex LC optical port, esetyenziswa ngokubanzi kwizicelo zokuhanjiswa kwemodi enye.Olu hlobo lwemodyuli ye-optical kufuneka isetyenziswe ngababini.Ngokomzekelo, imodyuli ye-1490nm / 1310nm ye-BIDI SFP ye-optical kufuneka isetyenziswe kwi-pair kunye ne-1310nm / 1490nm imodyuli ye-BIDI SFP ebonakalayo.

Imodyuli yokubona ye-DWDM SFP:Imodyuli ye-DWDM ye-SFP ye-optical yinxalenye eyimfuneko kwinethiwekhi ye-DWDM.Isebenzisa i-DWDM wavelength kwaye ineendlela ze-40 eziqhelekileyo zokukhetha.Yimodyuli ephezulu yokuhanjiswa kwedatha ye-serial optical data.

Imodyuli yokubona ye-CWDM SFP:Imodyuli ye-CWDM ye-SFP ye-optical module yimodyuli ye-optical esebenzisa iteknoloji yeCWDM.I-wavelength yayo yokusebenza yi-CWDM ye-wavelength kwaye kukho iziteshi ze-18 ze-wavelength ukukhetha kuzo.Njengemodyuli ye-SFP yesiqhelo ye-optical, imodyuli ye-CWDM ye-SFP ye-optical nayo i-hot-pluggable input / output (I / O) isixhobo esisetyenziswe kwi-SFP interface yokutshintsha okanye umzila.

Ixabiso kunye nokusetyenziswa kweemodyuli ezahlukeneyo ze-SFP optical zihlukile, kwaye iimodyuli ezifanayo ze-SFP ezibonakalayo eziveliswe ngabavelisi abahlukeneyo ziya kuba nokuhluka okukhulu ekusebenzeni kunye nexabiso.Abathengi kufuneka baqwalasele ixabiso, ukusetyenziswa, ukuhambelana, kunye nokuhambelana xa kuthengwa iimodyuli ze-SFP optical.Ukuqwalaselwa ngokubanzi kwemiba emininzi efana nebrand.
