Kev siv Bidi optical module tuaj yeem txo ntau cov chaw nres nkoj ntawm cov iav fiber vaj huam sib luag thiab qhov chaw mob siab rau cov tswj fiber ntau, thaum txo cov xov tooj ntawm cov kho qhov muag xav tau thiab txo tus nqi ntawm fiber cabling infrastructure. Koj paub dab tsi txog bidi optical module?
Lub ntsiab lus ntawm ib leeg fiber bidirectional optical module
Bidi optical module yog cov qauv siv kho qhov muag siv WDM (wavelength division multiplexing) bidirectional kis tau tus mob, uas tau lees paub qhov kev xa mus rau kev sib kis hauv cov channel kho qhov muag ntawm ib qho fiber tib lub sijhawm. Txawv ntawm qhov ntsuas qhov ntsuas hluav taws xob tshwj xeeb (nrog ob qhov sib txuas ntawm cov iav fiber ntau), bidi optical module muaj tsuas yog ib qho nkaus xwb, uas sib kis thiab tau txais cov cim ntawm ib qho kho qhov muag cable los ntawm kev sib txuas nrog bidirectional coupler.
Ua haujlwm cov ntsiab lus ntawm bidi optical module
Lub ntsiab sib txawv ntawm bidi optical module thiab tsoos dual fiber bidirectional optical module yog tias bidi optical module tau nruab nrog wavelength faib multiplexing (WDM) txuas ntxiv, uas yog, duplexer, uas tuaj yeem sib txuas thiab cais cov ntaub ntawv kis ntawm ib tus fiber ntau raws li nyias wavelengths. Vim li no, bidi optical module tseem suav tias yog WDM optical module.
Txhawm rau kom ua haujlwm tau zoo, kev sib tw rau cov qib kho qhov muag yuav tsum raug siv hauv khub. Los ntawm kev kho lub duplexer kom phim cov yam xav tau ntawm lub suab yoj ntawm lub transmitter thiab txais, twv qhov sib kis tau ntawm cov ntaub ntawv tuaj yeem paub. Piv txwv, yog tias qhov paired bidi optical module txuas nrog rau lub cuab yeej a (uplink) thiab ntaus B (downlink).
Qhov zoo ntawm bidi optical module
Cov txiaj ntsig pom tseeb tshaj plaws ntawm kev siv bidi optical modules, xws li sfp + bidi thiab SFP bidi optical modules, yog txo tus nqi ntawm cov fiber cabling infrastructure. Kev sib twv rau cov khoom siv kho qhov muag txo qis tus naj npawb ntawm cov chaw nres nkoj ntawm cov iav jumper vaj huam sib luag, txo lub phaj chaw rau kev tswj hwm fiber ntau, thiab txo cov xov tooj ntawm cov kho qhov muag xav tau.
Txawm hais tias tus nqi ntawm bidi optical module (WDM optical module) yog siab dua li ntawm cov tsoos ob txoj kev kho qhov muag module, tus naj npawb ntawm lub teeb siv ib chav kis nrug deb yog txo los ntawm ib nrab. Rau ntau cov tes hauj lwm, tus nqi ntawm kev siv cov tshuaj fiber tsawg yog qhov ntau tshaj li qhov kev yuav khoom kuj ntawm dual fiber bidirectional optical module.
Taw qhia ntawm cov roj carbon fiber tibireirectional optical module hom
Cov khoom muag (bidi optical module) tuaj yeem raug faib ua bidi SFP, bidi sfp +, bidi XFP thiab bidi x2.
Bidi SFP optical module
Bidi SFP optical module siv los xa thiab txais ntau qhov sib txawv nruab nrab yoj yob hauv ob qho kev qhia los ntawm WDM thev naus laus zis, thiab ib qho fiber ntau tau thov rau qhov ua haujlwm siab ua ke cov ntaub ntawv txuas ntxiv. Yog tias qhov kis tau mus deb li ntawm 40km, qhov kev twv twv SFP optical module nrog ntev ntawm 1310nm / 1550nm thiab 1310nm / 1490nm yuav tsum raug xaiv; yog tias qhov kis tau mus deb tshaj 40km, qhov ntsuas hluav taws xob nrog cov nthwv dej ntawm 1550nm / 1490nmbidi SFP yuav tsum tau xaiv.
Bidi sfp + kho qhov muag
Bidi sfp + optical module yog ib hom kev txhim kho ntawm SFP optical module, nrog tus nqi ntawm 10G. Nws yog siv hauv cov bidirectional 10g serial kho qhov muag sib txuas ntawm 1330 / 1270nm transmitter thiab 1270 / 1330nm receiver. Nws yog tsuas yog siv hauv 10GBASE LR Ethernet, 10g LW fiber ntau channel fiber ntau channel thiab lwm cov teb.
Bidi x2 optical module
Lub twv twv x2 optical module yog tsim ntawm 1330 / 1270nm DFB laser nyob rau hauv qhov chaw kis, thiab cov kis tau txais siv cov kev sib xyaw 1270 / 1330nm preamplifier thiab cov lus tshaj tawm, uas yog siv rau hauv kev sib txuas lus muag khoom 10g serial optical sib txuas lus.
Bidi XFP optical module
Bidi XFP optical module yog XFP MSA optical module nrog built-in digital kuaj muaj nuj nqi. Nws txoj kev sib kis thiab txais cov wavelengths yog 1330nm / 1270nm thiab 1270nm / 1330nm feem. Feem ntau, nws yog siv nrog band SMF, thiab qhov sib kis tau ntev tshaj plaws tuaj yeem ncav cuag 10km. Lub zog noj ntawm bidi XFP optical module tsawg dua 2W, thiab nws tau thov rau 10G Ethernet.
Qhov sib txawv ntawm ib leeg fiber bidirectional optical module thiab ob chav fiber bidirectional optical module
Los ntawm kev qhia tawm ntawm ib leeg fiber bidirectional optical module saum toj no, qhov sib txawv ntawm ib leeg fiber bidirectional optical module thiab ob chav fiber bidirectional optical module yog pom tseeb.
1. WDM thev naus laus zis siv nyob rau hauv ib qho tib lub fiber ntau bidirectional optical module, tab sis dual fiber bidirectional optical module tsis siv;
