FBT Splitter vs. PLC Splitter: Qhov txawv yog dab tsi?
Dec 29, 2025| Taw qhia rau Fiber Optic Splitters
Fiber optic splitters faib cov teeb liab kho qhov muag hla cov tes hauj lwm. FBT (Fused Biconical Taper) splitters fuse thiab ncab fibers kom faib lub teeb. PLC (Planar Lightwave Circuit) splitters siv silica chips nrog etched waveguides. Qhov kev xaiv cuam tshuam rau tus nqi, scalability, thiab kev ntseeg siab. Cov ntawv tshaj tawm kev lag luam tau lees paub tias PLC txais yuav tam sim no tshaj 75% hauv kev xa tawm tshiab vim qhov chaw nres nkoj ntau dua.
Cov Ntsiab Cai Ua Haujlwm Tseem Ceeb
FBT Splitter Kev Tsim Kho:
Ob los yog ntau dua fibers fused thiab tapered manually
Cov teeb liab sib cais los ntawm kev sib txuas hauv thaj chaw fused
Kev sib cais tsis sib haum (piv txwv li, 70:30)
PLC Splitter Kev Tsim Kho:
Waveguides lithographically etched rau ntawm silica nti
Lub teeb faib sib npaug ntawm Y- ceg
Precision splitting (piv txwv li, 50:50 hauv 1x2)
Cov qauv sib txawv cuam tshuam qhov loj: FBT units yog 2-4 cm ntev; PLC chips haum rau hauv 1-2 cm modules.
Kev ntsuas kev ntsuas kev sib piv
| Parameter | FBT Splitter | PLC Splitter |
|---|---|---|
| Insertion Loss | Siab dua (piv txwv li, +0.5 dB) | Tsawg (-0.5 dB) |
| Kev tsis sib xws | ± 7 dB kev hloov pauv | ± 3 dB kev hloov pauv |
| Temp Range | -5℃rau 75 degree | -40℃rau 85 degree |
| Kev them nyiaj yug Wavelength | Ib qhov rais (piv txwv li, 1310nm) | Tag nrho spectrum (1260-1650nm) |
Manufacturing & Cost Analysis
FBT Production:
Ua haujlwm- hnyav: Cov kws tshaj lij fuse / taper fibers (1–2 teev / chav tsev)
Cov khoom siv qis; cov khoom khib nyiab siab
Kev lag luam hauv qab 1x8 splits ($ 15 / chaw nres nkoj)
PLC ntau lawm:
Automated wafer ua haujlwm (100+ chips/batch)
Tus nqi pib lithography siab; pheej yig dua ntawm nplai
Tus nqi -zoo tshaj 1x16 ($40 rau 1x32 vs. FBT's $65)
Optcore 2023 cov ntaub ntawv qhia PLC cov nqi poob 60% ntawm 1k-unit xaj.
Daim ntawv thov -Kev tsim nyog tshwj xeeb
Xaiv FBT Thaum twg:
Kev xa tawm hauv cov neeg nyob deb nroog/tsawg- ceev FTTH
Xav tau kev sib cais asymmetric (xws li CATV)
Ua haujlwm ruaj khov, chav - qhov kub thiab txias
Xaiv PLC Thaum twg:
Kev tsim kho siab -cov chaw khaws ntaub ntawv ceev/GPON
Requiring >1x16 splits nyob rau hauv compact modules
ntsib qhov kub thiab txias (piv txwv li, suab puam enclosures)
Cablestogo cov kev tshawb fawb teb qhia 34% qis dua PLC tsis ua hauj lwm hauv cov huab cua hnyav.
Cov txheej txheem xaiv
Xav txog cov xwm txheej no:
Chaw nres nkoj suav: FBT tsawg dua lossis sib npaug 1x8; PLC rau ntau dua lossis sib npaug rau 1x16
Ib puag ncig: PLC rau<-10°C or >75 degree; FBT rau kev tswj xyuas
Nyiaj txiag: FBT qis dua $20/split; PLC rau scalable tej yaam num
Teeb liab rhiab heev: PLC rau qhov tseem ceeb tsawg- poob / siab- cov apps tsis sib xws
Tsis txhob sib xyaw ua ke hauv cov tes hauj lwm cascaded-kev sib txuas tsis sib xws ua rau muaj teeb meem degradation.
Yav Tom Ntej Evolution & Hybrid Solutions
Multicore PLC: Pab kom 1x128 splits hauv cov qauv nti loj
Automated FBT: Robotics txiav cov nqi tsim khoom los ntawm 30%
Hybrid Designs: FBT rau lub cev kab + PLC rau kev faib khoom
Kev lag luam kws tshuaj ntsuam xyuas qhov project PLC yuav ua tus thawj 90% ntawm kev sib cais los ntawm 2028, nrog FBT tshwj tseg rau cov kev xav tau asymmetric niche.
