Fiber optic connectors yog dav dav -khoom siv passive. Cov kev sib txuas ntawm tib hom feem ntau tuaj yeem ua ke thiab rov qab siv dua, nrog qhov ua rau poob ntxiv feem ntau tsawg dua 0.2dB. Cov neeg tsis paub txog fiber ntau optics yuav yuam kev ntseeg tias GBIC thiab SFP modules siv tib lub fiber optic connector, tab sis qhov no tsis raug. SFP modules siv LC fiber ntau optic connectors, thaum GBIC modules siv SC fiber optic connectors. Hauv qab no, peb yuav muab cov lus piav qhia ntxaws ntxaws ntawm ntau yam fiber ntau optic connectors siv nyob rau hauv kev sib txuas lus tes hauj lwm, thiab kuj qhia txog qee qhov tsis tshua pom cov connectors.
PC/UPC/APC Fiber Hla-Section
Tus ntoo khaub lig- ntu ntawm fiber ntau optic connectors yuav tsum tau muab faib ua PC, UPC, thiab APC. Ntawm lawv, PC thiab UPC muaj fiber ntau optic microsphere kawg lub ntsej muag uas yog sib npaug rau lub ntsej muag kawg ntawm lub cev ceramic, thaum APC muaj fiber ntau optic microsphere kawg ntsej muag uas nyob ntawm 8℃kaum rau lub ntsej muag kawg ntawm lub cev ceramic.
Hauv lub neej niaj hnub, peb feem ntau tsis meej pem los ntawm cov neeg siv khoom thov rau PC / UPC / APC fiber ntau optic thaj qaum. Yooj yim muab, PC thaj qaum tuaj yeem nkag siab tias yog network- qib thaj qaum, thaum UPC/APC thaj qaum yog cov cab kuj- qib patch cords. Qhov sib txawv nyob rau hauv kev ua hauj lwm ntawm lawv cov connector taub hau thiab lub patch qaum poob; UPC / APC patch cords yog ua tau zoo thiab muaj kev poob qis.
PC hais txog kev sib cuag ntawm lub cev. Txawm hais tias ntawm cov khoom sib txuas ntawm lub cev, raws li lawv qhov rov qab poob, lawv tau muab faib ua PC, SPC, UPC, thiab APC. SPC stands rau super lub cev sib cuag, thiab UPC rau ultra lub cev tiv tauj. Cov qauv kev lag luam rau kev poob rov qab rau PC, SPC, thiab UPC yog -35dB, -40dB, thiab -50dB, ntsig txog (rov qab poob yog hais txog qhov feem pua ntawm cov teeb pom kev los ntawm lub ntsej muag kawg; qis rov qab poob zoo dua, txawm hais tias tus nqi siab dua kuj zoo dua, tsis quav ntsej cov cim tsis zoo). Cov sib txawv connectors yuav tsum tsis txhob muab sib xyaw rau hauv txoj cai. Txawm li cas los xij, lub ntsej muag fiber ntau ntawm PC, SPC, thiab UPC yog tag nrho cov tiaj tus; qhov sib txawv yog nyob rau hauv kev sib tsoo zoo. Yog li ntawd, kev sib xyaw PC, SPC, thiab UPC connectors tsis zoo li yuav ua rau lub cev puas tsuaj mus tas li.
APC yog txawv kiag li. Nws lub ntsej muag kawg yog hauv av ntawm 8-degree kaum sab xis kom txo qhov kev xav, thiab nws cov qauv kev lag luam rov qab poob yog -60dB. APC connectors tsuas yog txuas nrog lwm yam APC connectors. Vim tias cov qauv ntawm APC connectors yog txawv kiag li ntawm PC connectors, txuas ob hom connectors nrog flanges yuav ua rau lub fiber kawg lub ntsej muag ntawm connector. Txoj kev txuas APC rau PC yog siv lub PC-rau-APC fiber optic thaj qaum. Nws yuav tsum tau muab sau tseg tias APC connectors feem ntau yog ntsuab (thaum daj fibers tsuas yog ib hom fibers), thiab qaij ntawm lub ntsej muag fiber kawg yog pom ntawm qhov muag liab qab.
Fiber optic connectors
Fiber optic connectors tuaj yeem muab faib ua ntau yam. Raws li kev sib kis nruab nrab, lawv tuaj yeem muab faib ua ib qho -hom thiab ntau- hom fiber ntau optic connectors; Raws li cov qauv, lawv tuaj yeem muab faib ua FC, SC, ST, D4, DIN, Biconic, MU, LC, MT, thiab lwm yam; raws li tus pin kawg lub ntsej muag, lawv tuaj yeem muab faib ua FC, PC (UPC), thiab APC; thiab raws li tus naj npawb ntawm cov cores fiber ntau, lawv tuaj yeem muab faib ua ib qho -core thiab multi-core.
SC hom fiber ntau optic connector
Qhov no yog fiber ntau optic connector tsim los ntawm NTT Corporation ntawm Nyiv. Nws yog tus qauv square connector nrog lub plhaub sab nrauv ua los ntawm engineering yas, muab qhov zoo xws li kub tsis kam thiab tiv thaiv oxidation.
Lub optical interface ntawm cov khoom siv kis tau tus mob feem ntau siv SC connector. Nws tus pin thiab lub tes tsho coupling qhov ntev yog tib yam li FC hom.
Lub ntsej muag kawg ntawm tus pin yog feem ntau polished siv PC lossis APC hom; txoj kev fastening yog ib lub laub- rub latch hom, tsis tas yuav tig.
Cov connectors no yog pheej yig, yooj yim rau ntsaws thiab unplug, muaj qhov tsis tshua muaj qhov poob qis, siab compressive zog, thiab tuaj yeem ntsia tau rau hauv siab.
ST hom fiber ntau optic connector
Feem ntau siv nyob rau hauv fiber optic tis thav ntawv, lub plhaub txheej yog puag ncig thiab txoj kev fastening yog ntsia hlau fastener.
ST thiab SC connectors yog ob hom fiber ntau optic connectors. Rau 10Base-F kev sib txuas, qhov txuas feem ntau yog hom ST, thaum rau 100Base-FX, qhov txuas feem ntau yog hom SC. ST connector muaj ib tug raug connector core, thaum lub SC connector core nyob rau hauv lub connector.
LC hom connector
C- hom connector yog tsim los ntawm lub npe nrov Bell Labs thiab siv ib tug neeg siv - phooj ywg modular jack (RJ) latching mechanism.
Nws cov pins thiab lub tes tsho yog ib nrab ntawm qhov loj ntawm cov siv hauv cov qauv SC thiab FC connectors, ntsuas 1.25mm.
Qhov no tso cai rau kom muaj fiber ntau optic connector ceev nyob rau hauv fiber optic tis thav ntawv.
Tam sim no, LC hom connectors tau dhau los ua tus tseem ceeb hauv - hom SFF daim ntawv thov, thiab lawv daim ntawv thov hauv ntau hom kev siv kuj tseem loj hlob sai.
FC hom fiber ntau optic connector
Hom connector no yog Ameslikas tsim los ntawm NTT ntawm Nyiv. FC yog lub npe luv rau Ferrule Connector, qhia tias nws cov khoom siv sab nraud siv lub tes tsho hlau, feem ntau siv rau sab ODF. Hlau connectors muaj ntau mating voj voog tshaj cov yas, thiab txoj kev fastening yog ib tug ntsia hlau xov. Thaum ntxov FC hom connectors siv ceramic ferrules rau mating ports.
Hom kev sib txuas no muaj cov qauv yooj yim, yooj yim rau kev khiav lag luam thiab tsim khoom, tab sis lub ntsej muag fiber ntau yog rhiab rau plua plav thiab ua rau Fresnel xav txog, ua rau nws nyuaj rau kev txhim kho kev rov qab poob. Tom qab ntawd, hom kev sib txuas no tau txhim kho los ntawm kev siv cov ferrules nrog lub ntsej muag kheej kheej mating kawg (PC), thaum cov qauv sab nraud tseem tsis hloov pauv, ua rau muaj kev txhim kho tseem ceeb hauv kev poob thiab rov ua haujlwm poob.
MT-RJ hom connector
MT-RJ connector originated los ntawm MT connector tsim los ntawm NTT. Nws nta tib lub latching mechanism raws li RJ-45 LAN connector thiab aligns lub optical fiber siv cov lus qhia pins mounted rau ob sab ntawm ib lub tes tsho me me. Txhawm rau pab txhawb kev sib txuas nrog optical transceivers, connector kawg lub ntsej muag nta ib dual -core (0.75mm spacing) kho qhov muag fiber ntau. Nws yog ib tug tom ntej no - tiam high-density fiber optic connector feem ntau siv rau cov ntaub ntawv xa mus.
