Txoj Cai PLC Splitter rau Txhua FTTH Scenario: Ib Daim Ntawv Qhia Txog Kev Xaiv

Vim li cas PLC Splitters tau dhau los ua Tus Qauv Kev Lag Luam

Ua ntej kev tswj hwm ntawm PLC thev naus laus zis, FBT (Fused Biconical Taper) splitters yog qhov kev xaiv. Lawv yog tsim los ntawm twisting thiab fusing fibers ua ke, uas ua hauj lwm zoo rau me me phua ratios tab sis ua teeb meem raws li lub network teev. FBT splitters yog ntau wavelength-rhiab heev, tsis sib xws nyob rau hauv cov zis ports, thiab tsis ruaj khov nyob rau hauv qhov kub thiab txias.

PLC splitters, ntawm qhov tod tes, yog fabricated siv semiconductor manufacturing txheej txheem. Lub silica waveguide Circuit Court yog etched rau ntawm silicon nti, tsim ib txoj hauv kev kho qhov muag uas faib cov teeb liab tuaj rau hauv cov txiaj ntsig zoo kawg nkaus. Qhov tshwm sim yog ib qho khoom siv uas:

• Ua haujlwm thoob plaws qhov dav wavelength (1260-1650nm)

• Tswj kev sib cais zoo sib xws (feem ntau Tsawg dua lossis sib npaug rau 0.6 dB)

• Ua tau zoo los ntawm -40℃rau +85 degree

• Scales huv si mus txog 1 × 64 los yog txawm 1 × 128 splits

Hauv FTTH, PON, thiab cov ntaub ntawv chaw siv ntaub ntawv, PLC splitters tau dhau los ua qhov kev xaiv xaiv nyob qhov twg qhov kev ua tau zoo thiab kev ntseeg siab tsis tuaj yeem sib tham.

Cov Naj Npawb Qhov Tseem Ceeb

Thaum sib piv PLC splitters los ntawm cov chaw muag khoom sib txawv, peb qhov kev ntsuas kev tsim nyog tau txais kev pom zoo. Nov yog qhov kev ua tau zoo zoo li rau 1 × 8 splitter, tab sis cov hauv paus ntsiab lus siv thoob plaws txhua qhov sib faib.

Insertion Loss- Qhov no yog lub zog kho qhov muag poob thaum lub teeb liab dhau los ntawm lub splitter. qis dua yog zoo dua. Rau qhov ua tau zoo 1 × 8 splitter, cia siab tias qhov poob qis ib puag ncig Tsawg dua lossis sib npaug li 10.5 dB. Ib qho 1 × 32 splitter feem ntau yuav qhia tsawg dua lossis sib npaug rau 16.5 dB, thaum 1 × 64 tuaj yeem ncav cuag Tsawg dua lossis sib npaug li 20.5 dB. Kev nkag siab txog cov lej no yog qhov tseem ceeb rau kev suav koj lub network cov peev nyiaj kho qhov muag. GPON ib txwm muaj peev xwm siv nyiaj txog 28 dB ntawm OLT thiab ONT. Yog tias koj cov splitters ib leeg noj 20 dB ntawm qhov ntawd, koj muaj cov paj me me heev rau cov fiber ntau attenuation thiab connector poob.

Kev tsis sib xws- Qhov no ntsuas qhov ua tau zoo npaum li cas cov teeb liab tso tawm thoob plaws txhua qhov chaw nres nkoj. Ib qho tsis sib xws ntawm Tsawg dua lossis sib npaug ntawm 0.6 dB ua kom lub tsev txuas nrog rau qhov chaw nres nkoj 1 tau txais cov teeb liab zoo ib yam li lub tsev txuas nrog rau qhov chaw nres nkoj 32. Hauv kev xa tawm loj, qhov tsis zoo sib xws ua rau muaj kev sib txawv ntawm cov kev pabcuam uas nyuaj rau kev daws teeb meem. Piv txwv li, yog tias ib qho chaw nres nkoj poob 0.5 dB ntau tshaj qhov nruab nrab, qhov chaw nres nkoj yuav muaj qhov tsis tshua muaj txiaj ntsig rau yav tom ntej degradation - thiab cov neeg siv khoom ntawd yuav yog thawj tus tau ntsib teeb meem tsis sib xws thaum fiber ntau tau qias neeg lossis kub poob.

Rov Los Loss thiab Directivity- Rov qab poob (Ntau dua lossis sib npaug li 55 dB) ntsuas qhov zoo li cas lub splitter qhia txog cov cim tsis xav rov qab mus rau qhov chaw. Directivity (Ntau dua los yog sib npaug rau 55 dB) tiv thaiv cov teeb liab los ntawm kev tawm ntawm cov chaw nres nkoj tawm. Ob qhov kev ntsuas tseem ceeb hauv cov tes hauj lwm zoo. Kev coj tsis zoo tuaj yeem ua rau muaj kev sib tham ntawm cov neeg siv khoom ntawm tib ceg PON - qhov tsis tshua muaj tab sis tsis ua haujlwm tiag tiag.
