Dab tsi yog Cov Khoom Siv Optical Fiber Connectors? (Part 2)

Hauv daim ntawv lo qhia lub pigtailtxuas, peb feem ntau pom "FC/PC", "SC/PC" thiab lwm yam.

Nws lub ntsiab lus yog raws li nram no

Qhov ua ntej / qhia txog tus qauv txuas ntawm pigtail

"SC" kev sib koom ua ke yog cov qauv square sib koom ua ke, ua los ntawm cov yas engineering, uas muaj qhov zoo ntawm qhov kub thiab txias thiab tsis yooj yim oxidation. Qhov chaw nres nkoj kho qhov muag ntawm sab ntawm cov khoom siv kis tau tus mob feem ntau siv SC connector

Lub "LC" connector zoo ib yam li SC connector thiab me dua SC connector.

"FC" sib koom ua ke yog cov hlau sib koom ua ke, feem ntau yog siv rau sab ODF, thiab cov pluggable tooj ntawm cov hlau sib txuas yog ntau tshaj li ntau yam ntawm cov yas txuas, ntxiv rau peb qhov qhia saum toj no, muaj MTRJ, ST, MU, thiab yog li ntawd.

Tom qab "/" qhia txog cov txheej txheem fiber ntau, uas yog, txoj kev sib tsoo.

"PC" yog cov cuab yeej siv dav tshaj plaws ntawm cov neeg siv xov tooj, thiab nws qhov sib koom ua ke yog tiaj tus.

SC qhia tias pigtail connector yog SC connector. Sab optical interface ntawm cov khoom siv sib kis hauv kev lag luam feem ntau siv SC connector. SC connector yog tsim los ntawm engineering yas thiab tiv taus kub thiab oxidation. Lub optical interface ntawm ODF sab feem ntau siv FC connector, uas yog cov hlau txuas, tab sis ODF tsis muaj teeb meem kub. Cov hlau txuas tuaj yeem muab tso thiab tshem tawm ntau zaus dua li cov khoom siv yas, thiab ODF pigtail yog khaws cia ntau dua li optical pigtail. Lwm cov qauv sib txuas yog ST, DIN, thiab FDDI.

"PC" qhia txog kev sib koom ua ke ntawm fiber ntau optic hla ntu, PC yog qhov feem ntau. Tus qauv APC yog qhov siv tshaj plaws hauv kev tshaj tawm thiab CATV thaum ntxov. Lub taub hau pigtail siv lub ntsej muag kawg, thiab txoj kab nqes feem ntau tsis pom, uas tuaj yeem txhim kho qhov zoo ntawm lub teeb liab TV, feem ntau vim tias TV teeb liab yog analog teeb pom kev zoo, thaum lub coupling nto ntawm qhov sib koom ua ke yog ntsug, lub teeb pom kev zoo. rov los raws txoj kev qub. Txij li thaum lub uneven refractive index faib ntawm cov fiber yuav rov qab mus rau lub coupling nto dua, txawm hais tias lub zog yog heev me me, vim hais tias cov analog teeb liab tsis tau kiag li tshem tawm cov suab nrov, nws yog sib npaug rau superimposing ib tug tsis muaj zog teeb liab nrog ib tug ncua sij hawm ntawm cov thawj ntshiab. teeb liab. Hauv daim duab yog ob chav duab ntxoov ntxoo. Lub kaum sab xis ntawm pigtail headband tiv thaiv lub teeb pom kev los ntawm kev rov qab los ntawm txoj kev qub. Cov teeb liab digital dav dav feem ntau tsis muaj qhov teeb meem no.

Kuj tseem muaj cov txheej txheem "UPC", nws qhov lwj me dua li PC, thiab cov phaj txheej txheej ntawm cov khoom siv tshwj xeeb feem ntau yog FC / UPC. Lub jumper sab hauv ntawm ODF thav duab ntawm cov tuam txhab txawv teb chaws yog FC / UPC, uas txhim kho qhov ntsuas ntawm ODF ntaus ntawv nws tus kheej.

"PC" qhia txog kev sib koom ua ke ntawm fiber ntau optic hla ntu, PC yog qhov feem ntau. Tus qauv APC yog qhov siv tshaj plaws hauv kev tshaj tawm thiab CATV thaum ntxov. Lub taub hau pigtail siv lub ntsej muag kawg, thiab txoj kab nqes feem ntau tsis pom, uas tuaj yeem txhim kho qhov zoo ntawm lub teeb liab TV, feem ntau vim tias TV teeb liab yog analog teeb pom kev zoo, thaum lub coupling nto ntawm qhov sib koom ua ke yog ntsug, lub teeb pom kev zoo. rov los raws txoj kev qub. Txij li thaum lub uneven refractive index faib ntawm cov fiber yuav rov qab mus rau lub coupling nto dua, txawm hais tias lub zog yog heev me me, vim hais tias cov analog teeb liab tsis tau kiag li tshem tawm cov suab nrov, nws yog sib npaug rau superimposing ib tug tsis muaj zog teeb liab nrog ib tug ncua sij hawm ntawm cov thawj ntshiab. teeb liab. Hauv daim duab yog ob chav duab ntxoov ntxoo. Lub kaum sab xis ntawm pigtail headband tiv thaiv lub teeb pom kev los ntawm kev rov qab los ntawm txoj kev qub. Cov teeb liab digital dav dav feem ntau tsis muaj qhov teeb meem no.

Optical fiber interface yog lub cev interface siv los txuas kho qhov muag cables. Feem ntau muaj SC, ST, FC, thiab lwm yam, uas yog tsim los ntawm lub tuam txhab Japanese NTT. FC yog cov ntawv luv ntawm Ferrule Connector, uas yog sab nraud ntxiv los ntawm lub tes tsho hlau thiab nruj los ntawm lub tshuab tig. ST interface feem ntau yog siv rau 10Base-F, thiab SC interface feem ntau yog siv rau 100Base-FX.

Cov fiber ntau kho qhov muag tuaj yeem ua lub teeb nthwv dej ntawm sab hauv, uas tau muab faib ua ib hom (ua lub laser ntev) thiab ntau hom (ua lub laser luv luv). Qhov kev sib txuas ntawm ib hom kab hluav taws xob tuaj yeem ncav cuag li 10 km, thiab qhov kev sib txuas ntawm ntau hom cable yog luv dua, yog 300 meters lossis 500 meters (feem ntau nyob ntawm qhov txawv ntawm laser, feem ntau muaj ob hom luv. -wavelength laser teeb qhov chaw, ib qho yog 62.5, ib qho yog 50), ntxiv rau, kuj tseem muaj ob hom cable txuas. SC interface yog 1GB interface thiab LC interface yog 2GB interface.

Qhov kev lwj ntawm "UPC" yog me dua li ntawm "PC", uas feem ntau yog siv rau cov khoom siv nrog cov kev xav tau tshwj xeeb, thiab qee cov tuam txhab txawv teb chaws siv FC / UPC rau sab hauv jumper ntawm ODF thav duab, feem ntau los txhim kho qhov ntsuas ntawm ODF cov khoom nws tus kheej. .

Tsis tas li ntawd, tus qauv "APC" yog siv ntau dua hauv xov tooj cua thiab TV thiab CATV thaum ntxov, thiab nws lub taub hau pigtail siv lub ntsej muag kawg, uas tuaj yeem txhim kho qhov zoo ntawm lub teeb liab TV, feem ntau vim tias TV teeb liab yog analog teeb pom kev zoo thaum lub coupling nto ntawm qhov sib koom ua ke yog ntsug, lub teeb pom kev zoo rov qab los ntawm txoj kev qub. Txij li thaum lub uneven refractive index faib ntawm cov fiber yuav rov qab mus rau lub coupling nto dua, txawm hais tias lub zog yog heev me me, vim hais tias cov analog teeb liab tsis tau kiag li tshem tawm cov suab nrov, nws yog sib npaug rau superimposing ib tug tsis muaj zog teeb liab nrog ib tug ncua sij hawm ntawm cov thawj ntshiab. teeb liab, uas yog reflected nyob rau hauv qhov screen. Lub kaum sab xis ntawm pigtail headband tiv thaiv lub teeb pom kev los ntawm kev rov qab los ntawm txoj kev qub. Cov teeb liab digital dav dav feem ntau tsis muaj qhov teeb meem no.
