Ntau hom Common Fiber Optic Cables Thiab Patch Cables
1.FTTH Nyob Hauv Tsev Cable
FTTH (Fibre To Home), raws li nws lub npe qhia tias nws yog ib qho fiber optic ncaj qha mus rau tom tsev. Tshwj xeeb, FTTH hais txog qhov kev sib txuas ntawm lub network (ONU) nyob rau hauv cov neeg siv khoom hauv tsev los yog cov neeg siv lag luam, yog qhov siv tau cov ntaub ntawv tshaj tawm rau cov neeg siv nyob rau hauv qhov muag pom tshwj xeeb tsuas yog FTTD (fiber ntau rau lub desktop).
Nws muaj 5 qhov tseem ceeb ntawm FTTH:
Ua ntej, nws yog ib qhov kev pab cuam hauv lub cev, los ntawm qhov kawg rau tus neeg siv, tus intermediate yuav ua tau dhau passive;
Qhov thib ob, qhov kev siv bandwidth yog ib qhov dav, ntev ntev haum qhov kev siv loj heev;
Thib peb, vim nws yog kev lag luam nyob hauv fiber, thiab tsis muaj teeb meem;
Qhov plaub, vim nws txoj kev loj bandwidth, kev txhawb zog raws tu qauv ntau dua;
Thib tsib, nrog rau kev tsim technology, nrog rau point-to-point, 1.25G thiab FTTH tau tsim kom muaj kev ua tau zoo meej.
2. Hauv Chaw Fiber Optic Cable
Sab hauv optical cable yog cais raws li qhov chaw siv, li opposed fiber ntau optic cable.
Sab hauv optical cable yog cable ua kom muaj fiber ntau optic (optical kis tau tus mob nruab nrab) tom qab ib txoj hau kev. Feem ntau ntawm cov khoom siv fiber ntau (iav fiber yog li nyias plaub hau), yas tiv thaiv lub raj thiab yas tais. Yog tsis muaj kub, nyiaj, tooj liab thiab txhuas thiab lwm yam hlau, fiber ntau optic cable feem ntau tsis muaj txig rov qab.
Sab hauv fiber fiber optic cable yog ib qhov qee qhov muaj fiber ntau cov kab ua rau cable txuas raws li ib txoj hau kev, cov tsho tawm sab nrauv, thiab qee cov coated txheej tiv thaiv, kom tau txoj kev sib txuas lus ntawm lub teeb liab.
Sab hauv tsev nyob yog lub zog tensile me me, tsis muaj txheej txheem tiv thaiv, tab sis kuj yooj yim dua thiab pheej yig dua. Sab hauv tsev siv xov tooj cua hauv tsev, thiab kev sib txuas ntawm cov khoom siv network.
3. Sab nraum zoov Fiber Optic Cable
Sab nraum zoov fiber ntau optic cable, siv rau sab nraum zoov, qhov ntxeev ntawm cov hluav taws xob hauv tsev.
Sab nraum zoov cable yog hom kab kev sib txuas lus kom tau txais kev pom lub teeb pom kev zoo, yog tsim los ntawm ib qho nyiaj ntawm fiber ntau txoj kab ua rau cable core raws li ib txoj kev, outsourcing tsho, thiab qee cov coated nrog txheej tiv thaiv txheej txheem.
Sab nraum zoov cable yog tsuas yog muaj fiber ntau qhov muag (iav fiber yog li nyias plaub hau), yas tiv thaiv tube thiab yas tais. Yog tsis muaj kub, nyiaj, tooj liab thiab txhuas thiab lwm yam hlau kab, feem ntau tsis muaj nqi.
Sab nraum zoov cable yog lub zog tensile ntau, tuab txheej, thiab feem ntau yog npog (qhwv hauv hlau). Sab nraum zoov cov cables yog siv rau cov tuam tsev, thiab tej thaj chaw deb network sib txuas.
4.Fiber Optic Patch Cable
Fiber optic thaj cable, kuj hu ua fiber ntau jumper, siv los txuas ntawm lub cuab yeej mus rau fiber ntau optic cabling txuas. Fiber jumper muaj txheej txheem tiv thaiv, feem ntau yog siv rau txoj kev txuas ntawm fiber ntau lub tshuab hluav taws xob thiab Fiber Termination Box. Feem ntau siv fiber ntau lub thoob xws li: ST, LC, FC thiab SC.
Cov Pej Xeem Pawg
Hom ib hom fiber ntau kab: Hom dav ib qho qauv jumper yog xim hauv daj, sib txuas thiab tiv thaiv tes xiav; ntev kis nrug.
Hom ntau lub tshuab fiber ntau: Cov nplais loj ntawm cov nplais jumper yog xim nyob rau hauv cov txiv kab ntxwv thiab qee qhov grey, lub ntsej muag thiab kev tiv thaiv kev tiv thaiv yog xim dub los yog dub thiab qhov kis tau tus mob yog luv.
Fiber ntau optic jumper connector txhais:
SC Connector: square fiber optical connector;
FC Connector: puag ncig nrog xov;
ST Connector: zoo ib yam li BNC;
LC Txuas Hluav Taws Xob: kev sib cais ntawm kev sib cais tawm;
MT-RJ Connector: square, ib tug nrog ob leeg fiber;
PC Connector: hu tau ncaj qha;
APC Connector: 8 degree qaij kaum ntawm qhov sib cuag;
UPC Connector: ARC hu rau qhov chaw.
