SFP module yog dab tsi?
SFP yog cov ntawv luv ntawm cov pob me me pluggable. Nws yog compact, kub pluggable Optical module rau kev sib txuas lus thiab cov ntaub ntawv kev sib txuas lus daim ntaub ntawv. SFP Optical module tuaj yeem suav tias yog qhov hloov kho dua tshiab ntawm GBIC Optical module. Tsis zoo li GBICs nrog SC fiber ntau interfaces, SFPs tuaj nrog LC interfaces (txawm hais tias tseem muaj SFP modules nrog SC interfaces) thiab muaj lub cev loj ntawm tsuas yog ib nrab ntawm GBICs, cia SFPs txuag tau ntau qhov chaw. SFP txuas lub motherboard ntawm cov khoom siv network (xws lirouters, keyboards, media converters, or similar devices) to optical cables or cables. Nyob rau tib lub sijhawm, SFP yog ib qho kev siv dav dav siv los ntawm ntau tus neeg siv khoom siv network. Nws tau tsim los txhawb SONET, Gigabit Ethernet, Fiber Channel, thiab lwm yam qauv kev sib txuas lus. Cov duab yog qhia hauv daim duab hauv qab no
Standardization
SFP Optical module tsis yog tswj hwm los ntawm cov txheej txheem kev cai, tab sis yog tswj hwm los ntawm ntau qhov kev pom zoo (MSA) ntawm cov neeg sib tw. SFP yog tsim raws li GBIC interface thiab ua tiav qhov chaw nres nkoj siab dua GBIC (tus naj npawb ntawm Optical module ib centimeter raws ntug ntawm lub motherboard), uas yog vim li cas SFP tseem hu ua mini GBIC. Cov pob me me Optical module muaj qhov loj me zoo ib yam li SFP, tab sis nws yog soldered rau lub motherboard ua tus pin es tsis muab tso rau hauv daim npav sab.
Txawm li cas los xij, hauv kev siv tswv yim, qee lub tuam txhab tsim khoom siv network siv cov txheej txheem tseem ceeb los rhuav tshem kev sib raug zoo nrog "universal" SFP, uas yog, ntxiv cov txheej txheem pov thawj rau lub cuab yeej firmware kom lub cuab yeej tsuas tuaj yeem ua rau nws tus kheej Optical module.
Ntau hom SFPs
Muaj ntau ntau hom transmitters thiab receivers rau SFP modules muag nyob rau hauv lub khw niaj hnub no. Txoj kev no tso cai rau cov neeg siv xaiv qhov tsim nyog Optical module rau txhua qhov txuas sib txawv. Piv txwv li, nyob rau hauv tam sim no interface hom, kis tau tus mob yuav muab faib ua ib hom los yog multimode raws li txawv fiber ntau hom.
Raws li pom nyob rau hauv daim duab saum toj no, daim duab no qhia tau hais tias ib qho fiber ntau module ntawm SC interface
Raws li pom nyob rau hauv daim duab saum toj no, qhov no yog ib tug dual fiber module rau LC interface
Kev sib xyaw ntawm SFP
Cov qauv muaj pes tsawg leeg: feem ntau yog tsim los ntawm ib qho ntawm (BOSA rau ib qho fiber ntau; TOSA + ROSA rau ob chav fiber ntau), ua ke nrog PCBA board thiab plhaub, thiab nruab nrog rub rings, buckles, xauv qhov chaw, thiab roj hmab ntsaws. Txhawm rau kom paub qhov txawv ntawm qhov sib txawv emissions thiab txais tos wavelengths los ntawm cov tsos, cov xim sib txawv rub lub nplhaib feem ntau yog tsim los kom paub qhov txawv ntawm cov hom ntawm cov module. Piv txwv li, hauv LC ib qho fiber ntau interface, lub nplhaib xiav rub yog 1310nm, lub nplhaib rub lub nplhaib yog 1490nm, thiab lwm yam.
SFP module tsim los ntawm Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. yog cov khoom muag zoo tshaj plaws. Tsis tas li ntawd, tseem muaj kev sib txuas lus nrov Optical module, pluggable Optical module, 1x9 Optical module, dual core Optical module thiab lwm yam khoom module ntawm ntau hom. Zoo siab txais tos txhua tus neeg xav tau kev nkag siab txog cov khoom. Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. tuaj yeem muab cov kws tshaj lij kev pabcuam pabcuam pabcuam rau koj.
