1. Qhov Chaw Pib: Central Office ODF (High-Density Rack Mount)
Ntawm lub taub hau lossis chaw ua haujlwm hauv nruab nrab, kaum lossis ntau pua ntawm cov khoom noj fiber ntau raug txiav thiab hla kev sib txuas hauv Optical Distribution Frames (ODFs). Ntawm no, qhov chaw yog nyob ntawm tus nqi, thiab kev ua kom nrawm nrawm yog qhov tseem ceeb.
Yam xav tau:
• High chaw nres nkoj ceev nyob rau hauv ib tug me me hneev taw.
• Txhim khu kev qha, rov ua mating rau nquag reconfiguration.
• Xim coding kom paub meej qhov txawv ib hom los ntawm ntau hom lossis UPC los ntawm APC.
Pom zoo adapters:
• LC Duplex / LC Quad adapters- LC daim ntawv me me (1.25 hli ferrule) tso cai rau 48 fibers rau 1U vaj huam sib luag. Rau qhov ceev dua, LC Quad (plaub LC chaw nres nkoj hauv ib lub tsev) ntim ntau qhov chaw nres nkoj rau hauv tib qhov chaw.
• SC Duplex adapters- Tseem siv dav heev, tshwj xeeb tshaj yog nyob rau hauv keeb kwm yav dhau los lossis qis dua.
• MPO adapters- Rau cov pob txha txuas uas xav tau 12 lossis 24 fibers hauv ib qho kev sib txuas, feem ntau siv los txuas rau cov khoom siv hluav taws xob los yog kev sib txuas ceev ceev.
Nyob rau hauv nruab nrab chaw ua hauj lwm ib puag ncig, adapters feem ntau yog flange mount (ntsia hlau-taw rau lub vaj huam sib luag) kom ruaj ntseg thiab mus ntev kev sib raug zoo.
2. Lub Distribution Point: Sab nraum zoov / Corridor Termination Box
Thaum lub teeb liab tawm ntawm lub hauv paus chaw ua hauj lwm, nws mus los ntawm feeder cables mus rau ib tug txoj kev txee los yog ib tug txoj kev termination box (feem ntau mounted rau ntawm phab ntsa los yog ncej). Qhov no yog qhov twg ib qho khoom noj fiber ntau tau muab faib ua ntau yam poob fibers siv PLC splitters.
Yuav ua li cas ntawm no:
• Lub feeder cable raug txiav, feem ntau spliced rau pigtails.
• PLC splitter (piv txwv li, 1:8, 1:16, lossis 1:32) faib cov teeb liab.
• Cov kev sib cais tawm tau nthuav tawm ntawm cov chaw nres nkoj adapter, npaj txhij lees txais cov xaim xaim xaim mus rau ib tus neeg hauv tsev.
Pom zoo adapters:
• SC / APC simplex adapters – Dominant choice for FTTH drop connections because APC (angled physical contact) provides the highest return loss (>60 dB), qhov tseem ceeb rau PON kev xa mus rau qhov chaw uas muaj kev cuam tshuam tuaj yeem cuam tshuam.
• SC/APC rau SC/APC- Kev sib xyaw ua ke ntau tshaj plaws rau cov thawv xa khoom sab nraud.
• Flangeless los yog nrog lub cev compact- Ntau lub thawv davhlau ya nyob twg siv cov hloov pauv yam tsis muaj flanges mounting kom txuag tau qhov chaw sab hauv thiab tso cai rau ntau qhov chaw nres nkoj ib square inch.
Vim li cas ho tsis LC ntawm no?Hauv ntau cov qauv FTTH hauv cheeb tsam (xws li GPON / XGS-PON), SC / APC yog qhov cuam tshuam rau cov nroj tsuag sab nraud. LC muaj ntau dua nyob rau hauv cov chaw khaws ntaub ntawv lossis rau cov chav tsev khoom siv high-density. Rau cov thawv txiav tawm sab nraum zoov, SC / APC tseem yog tus qauv.
3. Kauj Ruam Kawg: Sab Hauv Tsev Phab Ntsa Outlet (Subscriber End)
Tam sim no lub teeb liab tau mus txog koj lub tsev. Cov xaim xaim xaim nkag los ntawm phab ntsa sab nrauv thiab xaus ntawm lub qhov hluav taws xob me me - feem ntau hu ua fiber phab ntsa phaj lossis lub thawv txiav. Qhov no yog qhov uas koj ntsaws rau hauv koj lub ONT (Optical Network Terminal) lossis ncaj qha rau koj lub router (yog tias nws muaj kev sib xyaw ONT).
Yam koj xav tau:
• Ib tug huv, user-friendly interface uas tiv thaiv lub fiber kawg.
• Feem ntau ib qho chaw nres nkoj fiber ntau, qee zaum ob (rau yav tom ntej kab thib ob lossis seem).
• Tau tshaj tus qauv patch cords uas txuas rau ONT.
Pom zoo adapters:
• SC / APC simplex (phab ntsa-phaj version)- Feem ntau nyob hauv FTTH xa tawm hauv tsev. Nws phim rau sab nraum zoov poob cable lub connector thiab ua kom zoo tib yam rov qab poob.
• LC / UPC- Qee qhov tshiab ONTs lossis routers nrog kev sib xyaw optics siv LC interfaces (tshwj xeeb tshaj yog hauv cov khoom siv compact). Nyob rau hauv tas li ntawd, ib tug luv luv hybrid thaj qaum (SC / APC rau LC / UPC) yog siv.
• Flangeless, snap-in tsim- Phab ntsa qhov hluav taws xob feem ntau siv adapters tsis muaj flanges sab nraud, uas txuas ncaj qha rau hauv lub ntsej muag.
• Daim ntawv tseem ceeb rau cov neeg siv kawg: Nco ntsoov xyuas seb koj ONT puas xav tau APC (ntsuab) lossis UPC (xiav) txuas. Kev sib xyaw ua ke tuaj yeem ua rau lub ferrule puas thiab ua rau kev ua haujlwm tsis zoo.
4. Tshwj xeeb Case: Hybrid Adapters rau Mixed Environments
Tsis yog txhua lub network tsis sib xws. Qee lub sij hawm koj yuav tsum txuas cov cuab yeej cuab tam qub nrog ib qho interface rau lub network tshiab nrog ib qho sib txawv. Qhov ntawd yog qhov uas hybrid adapters tuaj rau hauv.
Piv txwv los ntawm peb cov khoom kab:
• SC/APC rau SC/UPC –Tso cai rau lub xaim xaim nrog SC / APC txuas mus rau cov cuab yeej ntsuas lossis cov cuab yeej siv qub siv SC / UPC (tsis pom zoo rau PON txuas mus tas li, tab sis tsis muaj nuj nqis rau kev sim).
• LC / UPC rau SC / APC -Siv thaum cov ntaub ntawv qhov chaw thaj vaj huam sib luag (LC/UPC) yuav tsum tau pub FTTH sab nraum cov nroj tsuag (SC/APC) - feem ntau pom hauv MDU (ntau lub tsev nyob) ib puag ncig uas lub nraub qaum yog LC tab sis qhov poob yog SC / APC.
• FC/UPC rau SC/APC –Txhawm rau txuas cov cuab yeej cuab tam FC-raws li cov cuab yeej siv niaj hnub FTTH.
• Vim li cas lawv tseem ceeb:Hybrid adapters cawm koj los ntawm kev hloov tag nrho cov vaj huam sib luag lossis rov txiav cov cables. Lawv yog tus choj tus nqi tsim nyog thaum lub sijhawm hloov pauv network.
5. Cov Lus Qhia Txog Kev Xaiv los ntawm Node

6. Vim li cas cov Adapters zoo tseem ceeb rau "Qhov Ntsuas Kawg"
Qhov "meter xeem" los ntawm phab ntsa qhov hluav taws xob rau koj ONT feem ntau yog qhov tsis saib xyuas feem ntau ntawm lub network. Cov neeg siv pheej yig, tsis zoo patch cords los yog sib tov APC nrog UPC yuam kev. Ib qho kev qias neeg lossis tsis sib haum xeeb tuaj yeem qhia txog kev poob lossis kev xav kom ua rau muaj kev cuam tshuam kev sib txuas, qeeb qeeb, lossis tseem yuam koj ONT rov qab - txhua tus raug liam rau ISP, thaum tus neeg ua txhaum tiag yog $ 2 adapter.
Yog vim li cas peb ntawm Glory Optical tsim txhua lub adapter nrog:
• Precision-aligned ceramic sleeves - kom ntseeg tau tias tsis tshua muaj qhov poob (tsawg dua lossis sib npaug rau 0.2 dB raug).
• High-quality engineering yas vaj tsev- ruaj khov, nplaim-retardant (UL94-V0 muaj), thiab xim-coded kom tsis txhob sib tov.
• Kev sim nruj- txhua lub adapter batch raug kuaj rau qhov poob, rov qab poob, thiab kev ua haujlwm ruaj khov (1,000 mating cycles).
Xaus
Los ntawm lub hauv paus chaw ua hauj lwm ODF mus rau phab ntsa qhov hluav taws xob nyob rau hauv koj chav nyob, fiber optic adapters yog cov unsung heroes ntawm txhua txhua FTTH network. Xaiv hom yog - SC vs. LC, UPC vs. APC, flanged vs. flangeless - ntawm txhua qhov ua kom ntseeg tau tias koj lub network xa cov kev ceev thiab kev ntseeg siab uas koj cov neeg siv khoom xav tau.
Thaum koj tab tom npaj koj qhov project FTTH tom ntej lossis kho dua ib qho uas twb muaj lawm, cia txoj kev teeb liab coj koj. Thiab thaum koj xav tau cov adapters uas yuav tsis cia koj poob, tshawb txog Glory Optical qhov ntau yam - los ntawm tus qauv SC / APC mus rau high-density LC thiab hybrid hom.
