Optical Specifications
CWDM ib leeg fiber ntau ib sab OADM module
Q1: Dab tsi yog CWDM / DWDM OADM?
Optical drop/pass and drop/insert of single CWDM/DWDM channel for point to-point, ring- or bus configuration Tag nrho cov khoom siv hluav taws xob, tsis muaj hluav taws xob xav tau Tsawg-nqi transceivers siv tau, cov cuab yeej uas twb muaj lawm tseem tuaj yeem siv tau pob tshab rau tag nrho cov ntaub ntawv Tus nqi thiab cov kev cai nce txog 10 Gbit / s ib channel Ua raws li ITU-T CWDM / DWDM cov qauv
Q2: Koj muaj OADM hom dab tsi?
HTFuture CWDM OADM modules muaj nyob rau hauv Field Module ABS Yas Box, 19 "Rack Mount Chassis thiab LGX Hlau Cassette Box pob. kev cia siab rau qhov yooj yim ntawm fiber ntau tuav thiab lub zog txuag kev daws teeb meem.
Q3: Koj puas muaj 8-Channel MUX/DEMUX?
Yog lawm, 8-Channel CWDM MUX/DEMUX (CWDM-MUX-8=) tso cai rau koj kom multiplex/demultiplex yim cais raws rau hauv ib khub ntawm fiber ntau. Dual fiber yog siv rau ob qho tib si network thiab GBIC kev sib txuas. Lub yim muaj wavelengths yog 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm, thiab 1610nm.
Q4: Txog OADM?
Ib qho OADM tuaj yeem suav tau tias yog ib hom kev sib txuas ntawm optical cross-connect, dav siv hauv wavelength division multiplexing (WDM) systems rau multiplexing thiab routing fiber optic signals. Lawv xaiv ntxiv thiab tso tseg ib tus neeg lossis cov teeb tsa ntawm lub wavelength raws los ntawm qhov ntom ntom wavelength division multiplexing (DWDM) ntau cov kwj dej. OADMs yog siv los them nqi nkag mus rau ib feem ntawm qhov bandwidth hauv qhov chaw kho qhov muag tau dhau los ntawm cov khoom siv hluav taws xob hauv kab nrog qhov tsawg kawg nkaus ntawm cov khoom siv hluav taws xob.
Q5: Dab tsi yog passive thiab nquag hom ntawm OADM?
OADMs muaj hom passive thiab nquag nyob ntawm lub wavelength. Nyob rau hauv passive OADM, qhov ntxiv thiab poob wavelengths yog tsau ua ntej thaum nyob rau hauv dynamic hom, OADM tuaj yeem teem rau txhua lub wavelength tom qab kev teeb tsa. Passive OADM siv WDM lim, fiber ntau gratings, thiab planar yoj taw qhia hauv tes hauj lwm nrog WDM systems. Dynamic OADM tuaj yeem xaiv txhua qhov wavelength los ntawm kev muab cov kev xav tau yam tsis hloov nws lub cev kev teeb tsa. Nws tseem tsis tshua kim thiab hloov pauv ntau dua li passive OADM. Dynamic OADM tau muab cais ua ob tiam.
Q6: Peb theem twg OADM muaj?
Ib tug raug OADM muaj peb theem: ib tug optical demultiplexer, ib tug optical multiplexer, thiab nruab nrab ntawm lawv ib txoj kev ntawm reconfiguring txoj kev ntawm lub optical demultiplexer, lub optical multiplexer thiab ib tug txheej ntawm ports rau ntxiv thiab xa me nyuam roj hmab teeb liab. Lub MUX multiplexes lub wavelength channels uas yuav tsum tau txuas ntxiv mus los ntawm DEMUX cov chaw nres nkoj nrog cov los ntawm cov chaw nres nkoj ntxiv, mus rau ib qho kev tso zis fiber ntau, thaum DEMUX cais wavelengths nyob rau hauv ib qho input fiber rau cov chaw nres nkoj. Kev kho dua tshiab tuaj yeem ua tiav los ntawm fiber ntau thaj vaj huam sib luag lossis los ntawm kev hloov kho qhov muag uas coj cov wavelengths mus rau MUX lossis tso cov chaw nres nkoj. Tag nrho cov teeb pom kev zoo uas ncaj qha dhau OADM yog hu ua kev txiav-los ntawm txoj kev teeb, thaum cov uas ntxiv los yog poob ntawm OADM node yog hu ua ntxiv / poob lub teeb.
