Optical module technology, hom thiab xaiv

ib ,Kev saib xyuas ntawm optical modules

Optical module, tseem hu ua optical transceiver integrated module, yog qhov tseem ceeb hauv kev sib txuas lus fiber ntau optical. Lawv paub txog kev hloov pauv ntawm cov teeb liab kho qhov muag thiab cov teeb liab hluav taws xob, tso cai rau cov ntaub ntawv xa mus ntawm kev kub ceev thiab kev ncua ntev los ntawm kev sib txuas ntawm fiber ntau. Optical modules yog tsim los ntawm cov khoom siv optoelectronic, circuits, thiab casings, thiab muaj cov yam ntxwv ntawm kev kub ceev, kev siv hluav taws xob tsawg, thiab kev ntseeg siab. Hauv kev sib txuas lus niaj hnub no, cov khoom siv kho qhov muag tau dhau los ua cov khoom tseem ceeb kom ua tiav cov ntaub ntawv xa mus ceev thiab tau siv dav hauv cov chaw khaws ntaub ntawv, huab xam, hauv nroog cheeb tsam network, qaum tes hauj lwm thiab lwm yam. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm optical module yog hloov hluav taws xob rau hauv cov teeb liab kho qhov muag, xa lawv los ntawm cov khoom siv kho qhov muag, thiab hloov cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob ntawm qhov kawg tau txais. Tshwj xeeb, qhov kawg xa tawm hloov cov ntaub ntawv teeb liab mus rau hauv lub teeb liab kho qhov muag thiab xa mus rau qhov kawg tau txais los ntawm fiber ntau optical, thiab qhov kawg tau txais ces rov qab kho qhov muag teeb liab rau cov ntaub ntawv teeb liab. Nyob rau hauv cov txheej txheem no, qhov kho qhov muag module paub txog kev sib kis sib txuas thiab kev sib kis ntev ntawm cov ntaub ntawv.

二,Hom ntawm optical modules

1.Classification los ntawm ceev:

Raws li qhov ceev, muaj 155M / 622M / 1.25G / 2.125G / 4.25G / 8G / 10G. 155M thiab 1.25G feem ntau yog siv hauv khw. Cov thev naus laus zis ntawm 10G yog maj mam loj hlob, thiab qhov kev thov tau txhim kho nyob rau hauv kev nce siab.

2.Kev faib tawm los ntawm wavelength:

Raws li lub wavelength, nws muab faib ua 850nm / 1310nm /1550nm / 1490nm/ 1530nm / 1610nm. Lub wavelength ntawm 850nm yog SFP ntau hom, thiab kev sib kis deb tsawg dua 2KM. Lub wavelength ntawm 1310/1550nm yog ib hom, thiab kis tau tus mob nrug ntau tshaj 2KM.

3.Classification los ntawm hom:

(1)Multimode: Yuav luag tag nrho cov multimode fiber ntau yog 50/125um lossis 62.5/125um, thiab bandwidth (cov ntaub ntawv xa los ntawm fiber ntau) feem ntau yog 200MHz txog 2GHz. Multimode optical transceivers tuaj yeem xa mus txog 5 mais ntawm Multimode optical fibers.

(2)Tib hom: Qhov loj ntawm ib hom fiber ntau yog 9-10 / 125μm, thiab nws muaj qhov tsis muaj kev txwv bandwidth thiab poob qis dua ntau hom fiber ntau. Tib hom optical transceivers feem ntau yog siv rau kev sib kis mus ntev, qee zaum mus txog 150 txog 200 mais.

三 、 Technical parameters and performance indicators

Thaum xaiv thiab siv optical modules, koj yuav tsum xav txog cov kev qhia hauv qab no thiab cov ntsuas kev ua tau zoo:

1. Insertion poob: Insertion poob yog hais txog qhov poob ntawm optical signals thaum lub sij hawm kis tau tus mob thiab yuav tsum me me npaum li sai tau los xyuas kom meej cov teeb liab zoo.

2. Rov qab poob: Rov qab poob yog hais txog qhov kev xav tsis zoo ntawm cov teeb liab kho qhov muag thaum sib kis. Kev poob rov qab ntau dhau yuav cuam tshuam rau lub teeb liab zoo.

3. Polarization hom dispersion: Polarization hom dispersion yog hais txog qhov dispersion tshwm sim los ntawm cov pab pawg sib txawv ntawm cov teeb liab optical hauv cov xeev sib txawv. Nws yuav tsum tsawg li tsawg tau los xyuas kom meej lub teeb liab zoo.

4. Extinction ratio: Tus extinction ratio yog hais txog lub zog sib txawv ntawm qib siab thiab qib qis ntawm cov teeb liab optical. Nws yuav tsum tsawg li tsawg tau los xyuas kom meej lub teeb liab zoo.

5. Digital diagnostic monitoring (DDM): Cov kev kuaj xyuas digital muaj nuj nqi tuaj yeem saib xyuas cov xwm txheej ua haujlwm thiab kev ua haujlwm tsis zoo ntawm cov qauv hauv lub sijhawm los pab daws teeb meem thiab kev ua haujlwm zoo.

四 、 Kev ceev faj rau kev xaiv thiab siv

Thaum xaiv thiab siv optical modules, koj yuav tsum tau them sai sai rau cov hauv qab no:

1. Optical fiber specifications: Modules uas phim qhov tseeb optical fiber siv yuav tsum tau xaiv los xyuas kom meej qhov zoo tshaj plaws kis tau tus mob nyhuv.

2. Docking method: Cov qauv yuav tsum raug xaiv kom phim cov khoom siv tiag tiag kom ntseeg tau tias qhov chaw docking raug thiab ruaj khov.

3. Compatibility: Modules uas sib haum nrog cov cuab yeej tiag tiag yuav tsum raug xaiv kom ntseeg tau tias muaj kev sib raug zoo thiab ruaj khov.

4. Cov yam ntxwv ib puag ncig: Qhov cuam tshuam ntawm ib puag ncig yam xws li kub thiab av noo nyob rau hauv qhov siv tiag tiag ib puag ncig ntawm kev ua haujlwm ntawm module yuav tsum raug txiav txim siab.

5. Kev tu thiab tu: Lub module yuav tsum tau tshuaj xyuas thiab tswj xyuas tsis tu ncua kom ntseeg tau tias nws ua haujlwm ruaj khov mus ntev.
