Fiber optic splitter, kuj hu ua optical splitter, Yog ib qhov tseem ceeb tshaj plaws passive li hauv optical fiber txuas.
Nws yog ib tug ntaus ntawv los twb paub lawm lub teeb yoj zog shunt.
Peb feem ntau siv M × N rau denote tias ib splitter muaj inputs thiab N tso zis.
Raws li tus thawj xibfwb ntawm optical SPLITTER, Optical SPLITTER yuav faib rau FBT SPLITTER THIAB PLC SPLITTER.
TUS FBT SPLITTER yog ib txoj kev scrambling ob (los yog ntau dua) fiber optic fibers tsis muaj lub coating,
Tus tshwj xeeb waveguide qauv nrog ob npaug cones daim ntawv nyob rau hauv thaj av ntawd heating.
Tib lub sijhawm, Nws melts ntawm kub thiab stretches rau ob tog.
Txawv splitting piv yuav tau txais los ntawm kev tswj cov twist angle thiab ncab ntev ntawm lub fiber.
Thaum kawg, Ib solidified adhesive pab raws li solidify lub taper cheeb tsam rau lub quartz substrate ua ntej inserting nws mus rau hauv lub stainless tooj liab.
creat PLC SPLITTER，Ib nruab nrab los yog semiconductor substrate yog processed siv photolithography, etching, thiab tsim cov txheej txheem los tsim ib qho optical waveguide.
Tus waveguide array txoj hauj lwm rau ntawm qhov chaw upper ntawm lub nti, Qhov twg cuag integrated shunt function.
Thaum kawg, Cov input thiab tso zis xaus rau cov channel fiber array yog coupled nrog rau ob hnub kawg ntawm lub nti thiab packaged.
Taw qhia rau PLC Splitter

Lub detection wavelength yog 1310/1490/1550/1625/1650nm.
kom zoo dua
- Cov tsis rhiab rau lub wavelength ntawm lub teeb, Li ntawd, nws yuav ntsib tus transmission xav tau txawv wavelengths.
- Lub spectrum txawm tias, thiab lub teeb liab yuav faib rau tus neeg siv txawm.
- Compact qauv, luaj li cas, Yuav ncaj qha mus rau hauv lub thawv uas twb muaj lawm hloov mus rau lub thawv, Tsis tas yuav tawm hauv ib qhov chaw loj.
- Muaj ntau channels rau ib tug ntaus ntawv xwb, uas yuav ncav cuag ntau tshaj 32 channels.
- Tus nqi channel nqi yog tsawg, Ceg Npe - ee, Cov cuab kev ntau cuab kev kom zoo dua. Tus tub ntxhais tshuab tivthaiv PLC splitter yog nti
Pros thiab Cons ntawm FBT splitter
Pros
- Taper coupler muaj ntau tshaj 20 keeb kwm thiab kev kawm, Muaj ntau daim khoom siv thiab tshuab tsuas siv tau, Thiab txoj kev loj hlob yog tsuas ob peb kaum ntawm PLC txawm ob peb puas
- Cov khoom nyoos yog npaj muaj nyob rau hauv daim ntawv quartz substrates, fiber optics, cua sov-shrinkable tubes, hlau tubes, thiab tsawg glue, tag nrho cov tsawg tshaj li $1. Peev depreciation nqi ntawm cov cav tov thiab instruments yog tsawg dua, Thiab tus nqi tsawg-channel splitters xws li 1 × 2,1 × 4 tsawg dua.
- Phua piv yuav real-time xyuas raws li qhov xav tau, thiab tus unequal splitter yuav tau ua.
cons
- Cov tsis rhiab rau lub optical wavelength, Li ntawd, tus ntaus ntawv yuav tsum tau xaiv raws li tus wavelength, Nws yog ib tug tuag defect hauv tus txheej txheem siv lub network-in-one vim hais tias cov teeb liab optical transmitted hauv lub 3-network-in-one muaj 1310nm, 1490nm, 1550nm thiab li ntawd, rau.
- Cov khaub ncaws yog tsis, Uas hais txog qhov hloov ntawm insertion poob txhua tso zis kawg ntawm tus optical splitter. Qhov txawv ntawm 1X4 yog hais txog 1.5 .DB, thiab qhov txawv loj yog saum toj no 1 × 8, Uas yuav tsis xyuas kom meej tias cov khaub ncaws spectral tis thiab tej zaum yuav muaj feem xyuam rau tag nrho transmission nyob deb li cas.
- insertion poob (TDL) Yog tus piv ntawm tso zis optical fais fab los input optical fais fab ntawm ib qhov chaw nres nkoj. Tus insertion poob yog ua los ntawm ob qhov chaw: Ib tug ntxiv poob thiab lwm yam yog tus spectral piv tau qhov zoo tshaj yuav; Tus insertion poob tsis yog tib yam vim hais tias cov spectral piv ntawm tus ntaus ntawv yog txawv, thiab tsis muaj ib tug txheej txheem.
- Lub ntim ntawm cov ntau yam (xws li 1 × 16,1 × 32) loj, Lub reliability yog tsawg dua, thiab muaj txwv qhov chaw.
Qhov sib piv ntawm FBT splitter thiab PLC splitter
Txhua ntaus ntawv muaj nws tus kheej kom zoo dua ntawd kev kawm thiab nqe, Thiab ob lub tshuab undergo qhov upgrades rau qhov chaw nyob lawv respective shortcomings.
Tus FBT splitter yog solving cov teeb meem xws li cov me me ntawm ib-lub sij hawm taper-rub thiab cov tsis niaj hnub zoo li
PLC splitter no kuj ua zoo kawg thiab kev siv zog los txo tus nqi.
Thaum tam sim no, Tus nqi ntawm ob li yog yuav luag tib yam saum 1X8, Thiab tus nqi ntawm planar waveguide splitters yuav zoo nrog qhov nce splitters.
Nyob rau hauv tej daim ntawv thov uas qhov luaj li cas thiab wavelength ntawm lub teeb tsis rhiab heev, Tshwj xeeb tshaj yog nyob rau hauv rooj plaub ntawm ceg ntoo,
Nws yog affordable xaiv cov taper optical splitter.
Xws li ywj siab transmission xaiv tsa ntawm 1310nm FBT splitter.
Lub TV yees duab network yuav xaiv cov 1550nm FBT splitter.
PLC splitters yuav siv nyob rau hauv rooj plaub ntawm multi-wavelength optical transmission thiab ntau cov neeg siv, Xws li peb-hauv-ib, FTTH, li ntawd, thiab thiaj li.
Specifications rau optical splitters
insertion poob
Tus insertion poob ntawm ib fiber optic splitter yog pes tsawg tus db ntawm txhua tso zis rau lub input teeb poob.
Ntxiv losses
Qhov ntxiv yog txhais li cov DB ntawm optical hwj huam poob rau tag nrho optical fais fab tuag ntawm tag nrho cov zis ports.
Rau optical fiber ntau couplers, Qhov ntxiv tsis yog ib index ntawm qhov zoo tshaj ntawm tus ntaus ntawv manufacturing txheej txheem.
Nws reflects qhov inherent poob ntawm tus ntaus ntawv manufacturing txheej txheem.
Lub insertion poob tsuas qhia cov zis tso zis raws li txoj cai ntawm txhua tso zis chaw nres nkoj, Uas tsis zoo xwb muaj qhov inherent poob zoo tab sis kuj considers cov cawv ntawm spectral piv.
Yog li ntawd, vim, Qhov txawv hauv insertion poob ntawm ntau fiber ob peb yuav tsis muaj kev cuam tshuam qhov zoo ntawm tus ntaus ntawv.
Beam piv
Tus splitting piv yog txhais li cov zis tso zis piv ntawm txhua tso zis chaw nres nkoj ntawm qhov optical splitter.
Nyob rau hauv daim ntawv thov kev pab, Peb yuav tsum txiav txim seb tus phua piv raws li lub teeb ntawm lub cev optical node.
Tus splitting piv ntawm ib optical splitter nyob ntawm tus wavelength ntawm lub teeb transmitted,
piv txwv, Ib optical splitter uas transmits 1.31 microns ntawm lub teeb muaj ib lub teeb 50:50 phua piv ntawm ob tso zis;
thaum 1.5 ΜM, nws yuav ua tau 70:30(Qhov no tshwm sim vim hais tias cov splitter muaj ib yam bandwidth.
Cov bandwidth ntawm lub teeb liab optical kis thaum tus phua piv yog qhov).
Li ntawd, thaum koj txiav txim ib optical splitter, Koj yuav tsum hais kom tus wavelength.
rho tawm
Tus kawm ntawv ntawm rho tawm refers rau lub peev xwm ntawm ib txoj kev optical splitter los rho tawm cov teeb liab optical teeb liab nyob rau lwm txoj kev optical paths.
Nyob rau hauv daim ntawv thov kev pab, kev rho tawm hauj lwm feem ntau yuav tsum tau mus cuag 40 DB saum tus ntaus ntawv.
Txwv tsis pub, Nws yuav muaj feem xyuam rau cov kev kawm ntawm lub kaw lus tseem.
Cob qhia:
Nyob rau hauv ib qho optical splitter, directivity piav cov nyhuv incoming teeb los ntawm ib qho tso zis rau adjacent tso zis.
PDL
PDL yog txhais li tus logarithmic piv ntawm cov hwjchim ntau yam tsawg kawg nkaus tom qab lub xeev polarization kis los ntawm tus ntaus ntawv uas yog ntsuas.
Nyob rau hauv daim teb kev sib txuas lus thiab sensing, PDL yog ib qho tseem ceeb heev indicator, Nws reflects lub sensitivity ntawm ib tug ntaus ntawv mus txawv polarization lub xeev.
Cov ntaub ntawv ntawm optical splitter
1. Tag nrho cov fiber-optic sib txuas lus 2. Fiber optic LAN, MIV 3. FTTH, FTB 4. Kev kuaj xyuas khoom, optical fiber amplifier
Nta optical splitter:
2. Tsis tshua muaj 2.1%. Low polarization sensitivity
3. Low insertion poob rau tej kev hloov tej kev hloov
