MultiModeNpuasFBT Tub Npis
MultiMode FiberFBT coupler yog txhawm rau ob los sis ntau qhov kev pom ua ke ua ke, thiab tom qab ntawd kos cov duab kos rau lub khob ua tshuab, thiab saib xyuas qhov kev hloov ntawm cov sib cais hauv lub sijhawm. Tom qab cov kev faib tawm qhov sib txig mus txog qhov yuav tsum tau ua tiav, lub suab sib xyaw xaus, thiab ib qho kawg ntawm Lub hauv paus fiber (qhov seem raug txiav tawm) yog siv raws li cov tswv yim kawg, thiab lwm qhov kawg siv los ua ntau cov zis kawg. Tam sim no, cov txheej txheem ntawm kev sib sau ua si me me tsuas tuaj yeem rub tawm qis dua 1 × 4 ntawm ib zaug. Rau cov khoom siv siab dua 1 × 4, ntau tus 1 × 2 tau sib txuas ua ke. Tom qab ntawd nws tau ntim rau hauv lub thawv splitter.
TusMainAdaum
(1) FBT tus txuas ntxiv muaj ntau dua 20 xyoo ntawm keeb kwm thiab kev paub. Ntau cov khoom siv thiab cov txheej txheem tsuas yog yuav tsum tau muab pov tseg. Txoj kev txhim kho tus nqi tsuas yog ib feem kaum lossis txawm tias ib puas ntawm PLC.
(2) Cov ntaub ntawv nyoos tsuas yog npaj tau quartz cov ntawv qis, cov hluav taws xob ntse, cov raj kub ntsws tau yooj yim, tub raj tsis muaj dej thiab cov kua nplaum tsawg dua, thiab tag nrho cov nyiaj tsis tshaj ib duas las. Thiab cov nqi rho tawm ntawm kev nqis peev hauv tshuab thiab cov twj paj nruag yog qhov tsawg dua, 1 × 2, 1 × 4 Txoj kev rho tawm qis-channel tau tsawg tus nqi. A
(3) Qhov sib cais feem tuaj yeem soj ntsuam hauv lub sijhawm tiag tiag raws li qhov xav tau, thiab kev sib cais tsis sib xws tuaj yeem ua.

Ob lub khoom siv no muaj lawv tus kheej zoo ntawm kev ua tau zoo thiab tus nqi, thiab ob tus txheej txheem thev naus laus zis tau hloov kho kom tsis tu ncua los kov yeej lawv qhov kev tsis pom zoo Lub tshuab ua kom sib txig sib xyaw ua ke daws cov teeb meem ntawm cov me me ntawm cov muab pov tseg cov neeg pov tseg thiab cov teeb meem tsis zoo; lub koob yees duab waveguide splitter tseem tab tom ua kom tsis muaj kev cuam tshuam los txo cov nqi. Tam sim no, tus nqi ntawm ob lub khoom siv dhau los 1X8 yuav luag zoo li qub. Qhov nce ntawm cov xov xwm shunt yog qhov raug nqi zoo dua. 2. Yuav ua li cas xaiv lub ntaus ntawv Yuav ua li cas xaiv ob lub twj siv no, qhov tseem ceeb yog kev xav los ntawm lub sijhawm ntawm kev siv thiab cov neeg siv xav tau. Hauv qee cov ntawv thov uas ntim thiab lub teeb ntog tsis rhiab heev, tshwj xeeb tshaj yog muaj ob peb qhov sib cais, nws tau zoo dua los xaiv lub taper hom optical splitter. Piv txwv, 1310nm taper hom splitter yog siv rau cov ntaub ntawv xa mus tsis tos leej twg. Xaiv 1550nm taper splitter; nyob rau hauv cov ntaub ntawv ntawm triple-ua si, FTTH, thiab lwm yam, uas yuav tsum muaj ntau lub yoj ntawm kev sib kis thiab cov neeg siv ntau dua, yuav tsum siv lub koob yees duab waveguide splitter. Txog tam sim no, cov tuam txhab lag luam feem ntau hauv tsev siv traction tap shunts rau FTTH cov tes hauj lwm sib tw. Qhov no vim tias ntau tus neeg tsim qauv tsis paub txog cov khoom siv PLC, thiab qee lub tuam txhab hauv Suav teb tsim cov khoom siv ntawd. Yuav luag tag nrho cov kev lag luam uas FTTH hauv Nyij Pooj thiab Tebchaws Asmeskas ua lag luam nyob hauv kev ua lag luam tiag tiag siv planar optical waveguide splitters.
