Txoj kev ua haujlwm thiab kev sib txuas ntawm pigtail hom optical fiber ntau lub thawv

Kev sib txuas lus fiber ntau muaj ntau yam zoo xws li kev sib kis ntau zaus bandwidth, muaj peev xwm sib txuas lus loj, thiab poob qis, thiab siv dav hauv ntau qhov chaw. Thaum lub teeb xa mus rau hauv cov khoom siv kho qhov muag, nws yuav tsim kev poob, uas yog tsim los ntawm kev sib kis ntawm cov khoom siv kho qhov muag nws tus kheej thiab fusion poob ntawm qhov sib txuas. Thaum cov khoom siv kho qhov muag raug txiav txim, qhov kev sib kis ntawm cov fiber ntau optical nws tus kheej yog qhov pib txiav txim siab, thaum lub fusion poob ntawm qhov kho qhov muag fiber ntau yog cuam tshuam nrog cov fiber ntau optical nws tus kheej thiab kev tsim kho ntawm qhov chaw.
Hauv kev sib txuas network, fiber ntau optic cables feem ntau yog siv sab nraum zoov (kev sib txuas ntawm cov tsev), thiab Ethernet twisted khub cables yog siv sab hauv tsev (sab hauv tsev).
Kauj Ruam 1: Sab nraum zoov kho qhov muag cable txuas nrog lub thawv davhlau ya nyob twg, lub hom phiaj yog fuse cov fiber ntau optical thiab pigtail hauv qhov kho qhov muag cable, thiab coj nws tawm ntawm lub jumper.
Kauj Ruam 2: Txuas lub fiber optic jumper mus rau fiber ntau optic transceiver, lub hom phiaj yog los hloov cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob.
Kauj Ruam 3: Cov fiber ntau optic transceiver ua rau cov teeb liab hluav taws xob, thiab qhov nruab nrab kis tau siv yog ob leeg twisted. Lub sijhawm no, tus khub twisted tuaj yeem txuas nrog RJ-45 chaw nres nkoj ntawm lub network ntaus ntawv. Txog tam sim no, lub teeb liab photoelectric hloov dua siab tshiab tau ua tiav.
Nco tseg: Ntau lub network tam sim no muaj cov chaw nres nkoj kho qhov muag (optical fiber interfaces), tab sis yog tias tsis muaj qhov kho qhov muag module (zoo ib yam li kev ua haujlwm ntawm optical fiber transceivers), qhov chaw nres nkoj no siv tsis tau. Kev ua haujlwm ntawm lub thawv optical cable davhlau ya nyob twg: txhawm rau txiav qhov kho qhov muag cable thiab txuas cov tub ntxhais thiab pigtail hauv qhov kho qhov muag cable.
Pigtail: Muaj ib qho kev sib txuas ntawm ib qho kawg thiab qhov kawg tawg ntawm cov tub ntxhais kho qhov muag ntawm lwm qhov kawg. Nws txuas nrog lwm cov fiber ntau optical cores los ntawm fusion splicing. Nws yog siv nyob rau hauv lub thawv davhlau ya nyob twg los txuas cov fiber ntau hauv qhov kho qhov muag cable, thiab txuas lub pigtail thiab jumper los ntawm lub davhlau ya nyob twg lub thawv coupler (adapter). Lub luag haujlwm yog txhawm rau txuas cov khoom sib txuas ntawm ob qho kawg ntawm cov khoom siv fiber ntau. Ib qho kawg ntawm lub pigtail yog fused mus rau optical fiber connector, thiab lwm kawg yog kev cob cog rua rau lub optical fiber transceiver los yog optical fiber module los ntawm ib tug tshwj xeeb connector los tsim ib tug kho qhov muag cov ntaub ntawv kis tau tus mob txoj kev. Feem ntau, peb tsis tuaj yeem yuav cov pigtails dawb huv, tab sis jumpers raws li qhia hauv daim duab, fiber optic transceivers lossis fiber optic modules txuas nrog rau kev sib txuas ntawm cov ntaub ntawv kho qhov muag. Feem ntau, peb tsis tuaj yeem yuav cov pigtails dawb, tab sis jumpers raws li qhia hauv daim duab.
Jumper: Ob qhov kawg ntawm jumper yog cov khoom sib txuas. Ua lub luag haujlwm ntawm kev sib txuas pigtails thiab khoom siv. Optical cable davhlau ya nyob twg lub thawv yog ib lub thawv uas tiv thaiv lub optical cable thiab pigtail fusion ntawm lub davhlau ya nyob twg ntawm qhov kho qhov muag cable tso.
Optical fiber coupler: Nws yog siv rau kev sib txuas ntawm ob lub fibers optical lossis pigtails, feem ntau hu ua flange.
Optical fiber davhlau ya nyob twg lub thawv: Nws yog lub davhlau ya nyob twg connector ntawm ib tug kho qhov muag cable, ib kawg ntawm uas yog ib tug kho qhov muag cable, thiab lwm yam kawg yog ib tug pigtail, uas yog sib npaug rau ib tug ntaus ntawv uas splits ib tug kho qhov muag cable rau hauv ib tug optical fiber.
Fiber splice lub thawv: Nws yog siv los txuas ob lub kho qhov muag cables rau hauv ib qho kev kho qhov muag ntev. Lawv tsis tuaj yeem siv sib hloov. Lub optical cable thiab optical transceiver yog kev cob cog rua los ntawm lub fiber optic davhlau ya nyob twg lub thawv, uas yog, tsuas pigtails yuav tsum tau ntsaws rau hauv lub optical transceiver.
