Cov Lus Qhia Tshwj Xeeb

Kev faib tawm

Lub tshuab hloov kho tsoos kho qhov muag hloov pauv txoj kev kho qhov muag los ntawm kev txav ntawm cov kho qhov muag los yog cov khoom siv kho qhov muag (lens lossis tsom iav), thiab xa tawm los yog cuam tshuam lub teeb ncaj qha rau cov zis kawg. Mechanical optical hloov tsis haum rau kev hloov pauv loj loj hauv matrix thiab daim ntawv thov vim nws lub ntim loj thiab lub sijhawm hloov mus ntev, tab sis nws muaj cov tsis nkag siab tsawg, me me hla, rov ua dua zoo, ywj pheej ntawm tus kho qhov muag yoj yoj thiab polarization xeev, thiab yog pheej yig. Tsawg chaw nres nkoj 1 × 2, 2 × 2 kev hloov kho tshuab kho qhov muag yog qhov kev xaiv zoo tshaj plaws rau cov neeg siv. Txawm hais tias n × n (n> 2) arrays, cov hloov kho qhov muag tau muab sib dhos los ntawm 1 × 2 lossis 2 × 2 hloov. Nyob rau hauv thawj sim theem ntawm tag nrho cov kho qhov muag network, cov neeg kho tshuab kho qhov muag tseem ua lub luag haujlwm tsis sib xws.

Micro electro mechanical system kho qhov muag hloov - qhov nrawm yog qhov qeeb, feem ntau hauv kev txiav txim siab ntawm milliseconds, ntim loj, tsis yooj yim rau kev sib xyaw ua ke ntawm luv luv, txwv nws cov ntawv thov hauv thaj chaw ntawm kev sib txuas lus kho qhov muag yav tom ntej. Ntawm lub hauv paus no, MEMS kho qhov muag kho qhov muag tau tsim kho sai sai nyob rau hauv xyoo tas los no. Nws yog hom tshiab ntawm micro electro optical integrated hloov, uas yog tsim los ntawm kev sib txuas ntawm cov tshuab hluav taws xob semiconductor micromachining technology, micro optics thiab micromachining technology. Nws muaj qhov zoo ntawm cov ntaub ntawv pob tshab, polarization ywj pheej, qhov sib txawv me me, kev ntseeg tau zoo, kev nrawm nrawm thiab kev sib xyaw yooj yim. Nws tau dhau los ua lub peev xwm loj hloov mus rau qhov txuas optical network Hloov kho cov kev taw qhia txoj kev loj hlob ntawm txoj kev loj hlob.

Daim ntaub ntawv Sketch

Optical hloov yog ib hom kho qhov muag hluav taws xob hloov kho. Hauv cov hluav taws xob fiber ntau kis kab ke, cov khoom siv hluav taws xob tau siv rau kev hloov pauv ntawm ntau tus saib, LAN, ntau lub teeb pom, cov kab kuaj thiab tiv thaiv Ethernet. Hauv qhov kho cov kab ke fiber ntau, nws yog siv rau cov khoom siv fiber ntau, cov khoom siv fiber ntau kuaj thiab soj ntsuam network, thiab cov fiber ntau lub ntsiab lus tswj kev soj ntsuam.

Optical hloov ua lub luag haujlwm tseem ceeb hauv kev txuas network. Hauv wavelength faib multiplexing (WDM) kis tau tus mob, hloov kho qhov muag tuaj yeem siv rau kev yoj hluav taws xob, hloov kho dua tshiab thiab lub moos tawm; nyob rau hauv lub sij hawm kho qhov muag faib multiplex (OTDM) system, kho qhov muag yuav siv tau rau demultiplexing; nyob rau hauv txhua qhov kev hloov kho kab ke, kho qhov muag hloov pauv yog optical Hla txuas (OXC) yog lub cuab yeej tseem ceeb ntawm nthwv dej hloov dua siab tshiab. Raws li tus naj npawb ntawm cov tswv yim thiab cov chaw nres nkoj ntawm cov hloov kho qhov muag, nws tuaj yeem muab faib ua 1 × 1, 1 × 2, 1 × n, 2 × 2, 2 × n, m × N thiab lwm yam. Lawv muaj cov kev siv sib txawv hauv cov caij nyoog sib txawv.

Nws cov ntawv thov feem ntau muaj xws li: kev tiv thaiv kev hloov ntawm lub khoos phis tawm kho qhov muag, lub teeb hluav taws xob tswj hauv kev kuaj kab mob fiber ntau, kev ntsuam xyuas lub sijhawm tiag tiag ntawm cov kev ua haujlwm hauv network, kev sim cov khoom siv kho qhov muag, kev tsim kho hloov cov tub ntxhais ntawm OXC cov cuab yeej, kho qhov muag / demultiplexer, kuaj qhov muag , lub kaw lus kho qhov muag, thiab lwm yam.

Cov ntawv thov

1. Kev tiv thaiv kev hloov tshuab ntawm kho qhov muag network

2. Lub teeb ci ntawm qhov hluav taws xob tswj hauv qhov ntsuas fiber ntau

Lub 1 × 2 lub teeb tsa hluav taws xob yog feem ntau siv los hloov thiab tawm ntawm lub teeb hluav taws xob hauv qhov kho qhov muag fiber ntau.

3. Lub sijhawm saib xyuas lub sijhawm tiag tiag ntawm cov haujlwm network

4. Kev ntsuas ntsuas kho qhov muag

Kev tsim khoom thiab kev tshuaj ntsuam ntawm cov khoom siv tuaj yeem pom tau los ntawm kev siv 1 × n hloov kho qhov muag.

5. Tsim kev hloov pauv tseem ceeb ntawm cov khoom siv OXC

OXC tsuas yog siv nyob rau hauv caj qaum network los sib sau thiab sib pauv cov kev pabcuam ntawm cov subnets sib txawv. Vim tias OXC mas siv nyob rau hauv kev kub ceev thiab muaj peev xwm loj ntom nti sib faib sib faib ntau yam sib txuas sib txuas sab nraub qaum kho qhov muag, cov khoom siv kho qhov muag tau tsim kom muaj cov yam ntxwv ntawm kev ua kom pom kev, siab ceev, loj muaj peev xwm thiab ntau pob zeb hloov. Piv txwv li, n × n kho qhov muag hloov chaw matrices xws li 8x8, 16 × 16, 32 × 32, 64 × 64, 256 × 256 tuaj yeem tsim los ntawm kev siv 2 × 2 chav hloov kho qhov muag, uas yog cov khoom tseem ceeb ntawm OXC. OXC feem ntau ua kom tiav cov kev tswj hwm kev kho qhov muag, kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv, thiab tuaj yeem hloov kho kev pabcuam tshiab.

6. Kho qhov muag ntxiv poob multiplexing

0adm tsuas yog siv nyob rau hauv lub suab zoo li lub nroog thaj tsam network (tus txiv neej) kom paub txog qhov nce siab / qis lub suab ntawm txoj kab ntawm ib yoj yoj thiab ntau lub yoj yoj yoj los ntawm cov kab ke. Matrix hloov kho qhov muag yog qhov tseem ceeb ntawm 0adm. Nrog OADM, qhov hloov pauv nce / nqis wavelength tuaj yeem tswj tau los ntawm software, uas yuav ua rau muaj qhov hloov kho yooj yim ntawm lub network.

7. Optical sensing system

Lub 1 × n hloov kho qhov muag kuj tseem siv tau nyob rau hauv qhov chaw tso siab kom paub qhov chaw faib ntau yam thiab lub sij hawm faib multiplexing.

8. Kev kuaj qhov muag

1 × N thiab N × 1 cov twj siv tau kho qhov muag kuj tseem tuaj yeem ua cov ntawv thaij tsom iav ntawm cov iav sau
