SC APC Fiber Optic Connectors Ua tiav Phau Ntawv Qhia

Yog tias koj twb tau ntsia tom qab ntawm lub vaj huam sib luag fiber ntau thiab pom qhov sib xyaw ntawm ntsuab thiab xiav txuas, koj twb tau ntsib APC vs. UPC faib - txawm tias tsis muaj leej twg piav qhov txawv. Cov xim ntsuab yog APC. Thiab rau ntau cov ntawv thov network, lawv tsuas yog qhov kev xaiv uas ua rau kev nkag siab zoo.

Cov lus qhia no suav nrog SC APC connectors tshwj xeeb: dab tsi 8 - lub kaum sab xis ua tau rau koj lub teeb liab, qhov twg SC APC ua tau zoo dua lwm hom kev sib txuas, yuav ua li cas kom tsis txhob muaj teeb meem kev teeb tsa uas ua kom rov qab ua haujlwm tsis zoo, thiab thaum twg koj yuav tsum - thiab tsis txhob - xaiv APC dhau UPC.

Dab tsi ua rau SC APC txawv ntawm SC UPC?

Txhua qhov fiber ntau optic txuas ua haujlwm los ntawm kev ua kom ob lub iav fiber ntau cores kom lub teeb hla ntawm ib qho mus rau lwm qhov nrog tsawg tsawg. Qhov sib txawv ntawm APC thiab UPC los txog qhov tshwm sim rau qhov teeb meem ntawdtsis yogua nws hla kev sib txuas - rov qab xav txog.

UPC (Ultra Physical Contact)connectors muaj ib tug ca, me ntsis domed endface polished perpendicular mus rau lub fiber axis. Thaum lub teeb hits lub tiaj tus interface, ib feem me me qhia ncaj nraim rov qab rau hauv cov tub ntxhais fiber ntau. Lub teeb ci ntawd hu uaOptical Rov Los Loss (ORL), thiab nws ua rau muaj teeb meem - teeb liab suab nrov, laser instability, thiab me ntsis yuam kev - tshwj xeeb tshaj yog nyob rau hauv analog thiab siab -sensitivity digital systems.

APC (Angled Physical Contact)connectors daws qhov no los ntawm polishing lub endface ntawm ib8-degree kaum. Lub kaum sab xis redirects reflected lub teeb rau hauv lub fiber cladding es tsis txhob rov qab mus rau hauv lub tub ntxhais. Qhov tshwm sim: dramatically qis rov qab xav.

Cov lej qhia zaj dab neeg:

Ib daim ntawv qhia txog cov txiaj ntsig rov qab:Rov qab poob yog qhia raws li qhov zoo dB tus lej - siab dua yog qhov zoo dua. Kev poob rov qab ntawm 60 dB txhais tau hais tias lub zog cuam tshuam yog ib qho - lab ntawm cov teeb liab tawm tswv yim. Ntawm 50 dB (UPC), pom lub zog yog kaum -millionths. Qhov 10 dB qhov sib txawv no sawv cev rau 10 × qhov sib txawv ntawm lub zog cuam tshuam txog lub zog laser.

Qhov 10 dB qhov sib txawv ntawm qhov rov qab poob suab me me, tab sis nyob rau hauv cov ntsiab lus kho qhov muag nws yog 10 × txo nyob rau hauv kev xav txog lub zog. Rau GPON network nqa RF video overlay, lossis DWDM system khiav 96 raws ntawm qhov sib nrug nruj, qhov tseem ceeb ntawm kaum yog qhov sib txawv ntawm lub teeb liab huv thiab pom cov khoom cuav ntawm txhua qhov screen.

Txoj cai tseem ceeb: Tsis txhob ua phooj ywg APC txuas nrog UPC txuas. The angled endface of an APC connector will not make proper contact with a flat UPC endface. The result is an air gap that causes extreme insertion loss (often >3 dB) thiab tuaj yeem ua rau lub cev puas tsuaj rau ob qho tib si ferrule endfaces. Yog tias koj pom ntsuab ntsaws rau hauv xiav - lossis vice versa - disconnect tam sim ntawd.

Peb kawm qhov no ib txoj kev nyuaj. Ib tus neeg siv ntaub ntawv chaw nyob hauv New Jersey tau hu rau peb tom qab tag nrho cov kab ntawm PON OLTs tau mus rau hauv lub tswb nrov tom qab ib txwm ua haujlwm thaj chaw. Cov neeg ua haujlwm hmo ntuj tau rub lub thawv xiav SC UPC thaj qaum es tsis txhob ntsuab SC APC thiab hla - txuas 48 chaw nres nkoj. Txog thaum sawv ntxov, 23 SFP transceivers tau chij siab rov qab- qhov cuam tshuam tsis zoo, 6 tau ua rau cov neeg txais kev xav tau mus tas li, thiab lub ferrule endfaces ntawm txhua tus khub tsis sib haum tau pom pom cov qhab nia nyob rau hauv lub tshuab tsom. Tag nrho cov kev puas tsuaj: 29 hloov SFPs, 48 ​​hloov thaj qaum, thiab 14 teev ntawm kev poob qis. Tag nrho vim qhov tsis ncaj ncees lawm xim connector tuaj tawm ntawm lub thawv. Qhov $50,000 zaj lus qhia yog vim li cas peb qhia txhua tus installer:xyuas cov xim, kos lub adapter, xyuas txhua lub sijhawm.

SC Connector: Vim li cas Nws tseem nyob txhua qhov chaw

SC (Subscriber Connector, qee zaum hu ua "Standard Connector") yog ib qho kev lag luam staple txij thaum nws suav nrog hauv TIA-568 tus qauv. Nws lub laub- rub latching mechanism ua rau nws yog ib qho yooj yim connectors siv - tsis muaj twisting, tsis threading, tsuas yog nias rau hauv thiab rub tawm.

Cov yam ntxwv tseem ceeb ntawm covSC fiber ntau optic connector:

SC connectors tseem yog hom connector tseem ceeb hauv FTTH xa mus, passive optical networks (PON), CATV faib, thiab telecom sab nraum nroj tsuag. ThaumLC connectorstau txais hauv av hauv cov chaw zov me nyuam vim lawv cov ntawv me me, SC tuav ruaj khov rau hauv cov ntawv thov uas yooj yim ntawm kev tuav thiab kev ntseeg siab ntawm cov neeg kho tshuab muaj teeb meem ntau dua qhov chaw nres nkoj ceev.

Qhov twg SC APC Connectors yog txoj cai xaiv

Tsis yog txhua daim ntawv thov xav tau APC. Tab sis cov uas ua,tiag tiagua. Nov yog qhov twg SC APC yog qhov xav tau lossis xav tau:

FTTH / GPON / XGS-PON kev xa tawm.Txhua tus qauv PON loj (ITU-T G.984, G.987, G.9807) qhia txog APC connectors thoob plaws hauv optical distribution network. Yog vim li cas: PON systems siv cov splitters uas yog qhov tseem ceeb rau kev rov qab xav, thiab ntau qhov kev xa tawm FTTH nqa analog RF video overlay nrog cov ntaub ntawv digital. Cov kev xav rov qab los ntawm UPC connectors ua rau pom kev cuam tshuam ntawm cov channel video. Qhov no yog vim li cas txhua ODN tivthaiv - PLC splitters, thaj vaj huam sib luag, poob cables - siv SC APC hauv FTTH.

DWDM thiab WDM systems.Thaum koj tab tom multiplexing 40, 80, lossis 96 wavelength channels mus rau ib qho fiber ntau, txawm tias qhov kev xav me me tuaj yeem ua rau crosstalk ntawm cov kab uas nyob ib sab. APC txo qhov kev pheej hmoo no.

Analog CATV.Cable TV signals yog amplitude -modulated, ua rau lawv rhiab heev rau rov poob. Kev lag luam xyaum tswj hwm APC txuas rau txhua txoj hauv kev video analog.

Kev ntsuas thiab ntsuas.High-Qhov tseeb OTDR thiab cov khoom siv hluav taws xob kho qhov muag txuas feem ntau siv APC los tiv thaiv cov khoom siv ntsuas los ntawm lub teeb pom kev.

Ntev -haul thiab amplified systems.Erbium-doped fiber amplifiers (EDFAs) amplify txhua yam - suav nrog lub teeb pom kev. APC connectors ntawm amplifier input thiab output tiv thaiv lub hwj chim los ntawm destabilizing lub amplifier.

Thaum UPC zoo (thiab siv tau ntau dua)

Rau kev siv ntau hom fiber ntau, luv - mus txog ib qho - hom kev sib txuas, thiab cov ntaub ntawv hloov chaw - mus rau - hloov kev sib txuas uas qhov rov qab poob tsis yog qhov tseem ceeb, UPC connectors ua haujlwm zoo kawg nkaus thiab raug nqi tsawg. Feem ntau SFP / SFP + transceivers nyob rau hauv cov ntaub ntawv chaw ib puag ncig siv LC UPC. Tsis tas yuav dhau - qhia APC qhov twg daim ntawv thov tsis thov nws.

Nqe Lus Nug: Puas yog APC tsim nyog tus nqi?

SC APC connectors feem ntau raug nqi 15-25% ntau dua SC UPC - uas tau tsav los ntawm txoj kev sib tw ntau dua thiab kev ua haujlwm nruj dua. Ntawm ib txoj hlua khi, uas yog ob peb xees. Ntawm 10,000-chaw nres nkoj FTTH xa tawm, nws ntxiv.

Tab sis ntawm no yog lej uas tseem ceeb: ib lub tsheb thauj khoom ib leeg los daws teeb meem kev xav txog - cuam tshuam txog kev pabcuam raug nqi $ 150– $ 300 hauv kev ua haujlwm thiab lub sijhawm tsheb. Ib pawg ntawm cov khoom siv pheej yig UPC siv qhov twg APC tau teev tseg tuaj yeem ua rau kaum ob ntawm cov tsheb thauj khoom hla lub network lub neej. Peb tau pom ISPs siv $ 40,000 hauv Xyoo 1 kev pabcuam kev hu xovtooj uas rov qab mus rau qhov kev txiav txim siab yuav khoom uas txuag tau $ 800 ntawm cov khoom sib txuas.

Rau txhua daim ntawv thov uas cov chaw tsim khoom siv tau qhia txog APC - thiab uas suav nrog tag nrho PON, CATV, thiab DWDM kev xa tawm - APC tus nqi them rau nws tus kheej ua ntej thawj tus neeg yuav khoom mus nyob.

Kev Txhim Kho Qhov Zoo Tshaj Plaws rau SC APC Connectors

Lub kaum sab xis ntawm 8-degree uas ua rau APC connectors ua tau zoo dua kuj ua rau lawv tsis muaj kev zam txim rau kev ua haujlwm tsis zoo. Qee cov lus qhia los ntawm ntau xyoo ntawm kev xa tawm:

Ib txwm ntxuav ua ntej txuas.Ib qho hmoov av ib zaug ntawm APC endface ua rau muaj kev cuam tshuam ntau dua li ntawm UPC endface vim tias lub kaum sab xis ua rau muaj kev sib cuag ntawm qhov chaw me me. Siv ib qho -nias lub tshuab ntxhua khaub ncaws kom qhuav ua ntej - nws ceev ceev thiab tswj 90% ntawm kev sib kis. Yog tias lub ntsej muag tseem tsis tau tshuaj xyuas, ua raws li ntub dej -ces- txoj kev qhuav: lint- dawb so dampened nrog IPA (isopropyl cawv), ces qhuav so, ib txwm nyob rau hauv ib qho kev taw qhia. Tsis txhob rov- siv tib qhov chaw so ob zaug.

Ib qho kev nthuav dav feem ntau cov lus qhia tsis nco qab:hluav taws xob zoo li qub.Nyob rau hauv ib puag ncig qhuav - tshwj xeeb tshaj yog rhuab chav neeg rau zaub mov hauv lub caij ntuj no - APC ferrules nyiam cov khoom hauv huab cua xws li hlau nplaum. Koj ntxuav lub ntsej muag kawg, teeb lub connector rau 10 vib nas this, thiab nws qias neeg dua. Siv cov cuab yeej tiv thaiv- zoo li qub thiab txuas tam sim tom qab ntxuav. Tsis txhob ntxuav ib pawg ntawm cov connectors thiab rov qab mus ntsaws rau hauv.

Tshawb xyuas nrog lub tshuab fiber ntau.Peb tau pom cov kws tshaj lij "huv" qhov txuas, ntsaws rau hauv, thiab xav paub yog vim li cas qhov poob yog 1.5 dB. Ib qho 400 × kev tshuaj ntsuam xyuas qhia pom cov kab mob sib kis uas pom tsis tau ntawm qhov muag liab qab. Kev lag luam tus qauv (IEC 61300-}3-35) txhais cov txheej txheem dhau / tsis ua tiav rau kev ua kom huv huv - kawm thiab siv lawv.

Siv APC-rau-APC adapters nkaus xwb.SC APC adapters (cov vaj tsev ntsuab) muaj lub tes tsho sab hauv kev sib tw. SC UPC adapters (xiav vaj) yog tiaj tus. Kev sib xyaw ua ke ua rau muaj teeb meem huab cua sib txawv uas tau piav qhia saum toj no. Xyuas txhua tus adapter hauv thaj vaj huam sib luag ua ntej txuas.

hwm lub vojvoog khoov.SC APC thaj qaum feem ntau siv 2.0 hli lossis 3.0 hli jacketed cable. Qhov tsawg kawg nkaus khoov vojvoog yog 10 × txoj kab uas hla tsis muaj load, 20 × nyob rau hauv nro. Tshaj - nruj cable routing qab thaj vaj huam sib luag yog qhov feem ntau ua rau poob ntau dhau hauv kev teeb tsa. Rau qhov chaw- txwv kev xa tawm, xav txogkhoov-sensitive fiber (G.657.A2)patch cords uas zam 7.5 hli khoov vojvoog yam tsis muaj qhov poob loj.

Sau koj cov kev ntsuas.Tom qab txhua qhov kev sib txuas SC APC, ntsuas qhov poob qis nrog lub ntsuas hluav taws xob kho qhov muag. Sau tus nqi. Kev sib txuas SC APC zoo ntsuas 0.2-0.3 dB. Txhua yam saum toj no 0.5 dB yuav tsum tau muab ntxuav thiab rov ntsuas dua -; siab tshaj 0.75 dB yuav tsum tau hloov. Qhov no siv sijhawm 30 vib nas this rau ib qho kev sib txuas thiab txuag cov sij hawm ntawm kev daws teeb meem tom qab.

Troubleshooting Common SC APC Teeb meem

High insertion loss (>0.5 dB):Ntxuav ob lub connector endfaces thiab lub tes tsho adapter. Re- tshuaj xyuas thiab rov-test. Yog tias tsis muaj ntxiv lawm, lub ferrule endface tej zaum yuav raug khawb los yog chipped - hloov lub thaj qaum. Tshawb xyuas APC / UPC adapter mismatch.

Cov teeb liab tsis ruaj khov / hloov pauv lub zog:Feem ntau yog kev sib txuas xoob. Xyuas kom tseeb tias SC connector tau zaum tag nrho - koj yuav tsum hnov ​​thiab hnov ​​​​lub latch nyem. Kuj xyuas kom muaj qhov tawg ferrule, uas tuaj yeem ua rau muaj kev sib cuag.
