SFP qhov khoos phis tawj kho qhov muag yog qhov hloov pauv kub me me hauv pob SFP. SFP qhov kho qhov muag feem ntau yog tsim los ntawm lub laser. SFP kev faib tawm tuaj yeem muab faib ua kev faib tawm tus nqi, kev faib ntu ntu ntev, thiab kev faib tawm qauv.
SFP yog lub npe luv ntawm SMALL FORM PLUGGABLE, uas tuaj yeem nkag siab yooj yim raws li kev hloov kho tshiab ntawm GBIC. SFP tus qauv
Qhov ntim yog ib nrab qhov loj ntawm GBIC tus qauv, tsuas yog qhov loj me ntawm tus ntiv tes xoo. Koj tuaj yeem teeb tsa ntau dua ob npaug ntawm cov chaw nres nkoj ntawm tib lub vaj huam sib luag. Lwm txoj haujlwm ntawm SFP tus qauv yog qhov zoo ib yam li GBIC. Qee lub tuam txhab hloov pauv hu rau SFP module ua qhov me me GBIC (MINI-GBIC)

SFPClassification:
ClassificationLos ntawmTus nqi:
Raws li tus nqi, muaj 155M/622M/1.25G/2.125G/4.25G/8G/10G, 155M thiab 1.25G tau siv hauv khw. Lub 10G thev naus laus zis tau maj mam loj tuaj, thiab qhov kev thov tau txhim kho hauv kev nce qib.
ClassificationLos ntawmWavelength:
Raws li lub nthwv dej, muaj 850nm/1310nm/1550nm/1490nm/1530nm/1610nm, lub nthwv dej yog 850nm rau SFP multimode, qhov kev sib kis nrug yog qis dua 2KM, lub nthwv dej yog 1310/1550nm rau ib hom, thiab qhov kev sib kis yog siab dua 2KM . Hais lus sib txheeb, qhov no Tus nqi ntawm peb lub yoj yoj yoj yog pheej yig dua li lwm qhov.
Yog tias cov qauv liab qab tsis yooj yim dua, cov chaw tsim khoom yuav paub qhov txawv xim ntawm lub nplhaib rub. Piv txwv li, lub nplhaib rub dub yog ntau hom thiab lub nthwv dej yog 850 nm; xiav yog tus qauv nrog lub nthwv dej ntawm 1310 nm; daj yog tus qauv nrog lub nthwv dej ntawm 1550 nm. Ntshav yog tus qauv nrog lub nthwv dej ntawm 1490 nm.
ClassificationLos ntawm Hom:
Ntau hom
Yuav luag tag nrho cov kab hluav taws xob ntau yog 50/125um lossis 62.5/125um hauv qhov loj me, thiab bandwidth (cov ntaub ntawv xov xwm xa los ntawm cov fiber) feem ntau yog 200MHz txog 2GHz. Multimode optical transceivers tuaj yeem nqa txog 5 kilometers ntawm kev xa xov hla ntau hom fiber ntau. Lub teeb emitting diode lossis laser yog siv los ua lub teeb ci. Lub nplhaib rub lossis lub cev sab nrauv yog xim dub.
Hom ib leeg
Ib hom fiber ntau muaj qhov loj me ntawm 9-10/125µm thiab muaj qhov txwv bandwidth tsis muaj qhov kawg thiab cov yam ntxwv poob qis dua ntau hom fiber ntau. Ib leeg-hom kev kho qhov muag kho qhov muag feem ntau siv rau kev xa mus deb, qee zaum nce mus txog 150 txog 200 kilometers. LEDs nrog nqaim LD lossis cov kab spectral tau siv los ua lub teeb ci. Cov xim ntawm lub nplhaib rub lossis lub cev sab nraud yog xiav, daj lossis ntshav.
