MST vs ODF vs FDB: Yuav Ua Li Cas Xaiv Fiber Distribution Nodes

Peb Devices ntawm ib nrais muag

1. MST – Lub Hardened, Plug-thiab-Play Access Terminal

Nws yog dab tsi

Multiport Service Terminal (MST) yog qhov ua ntej -connectorized, ib puag ncig kaw enclosure tsim los rau sab nraum zoov fiber ntau xa tawm sai. Tsis zoo li ib txwm teb-splice terminals, ib qho MST los ntawm lub Hoobkas nrog cov khoom sib txuas uas twb muaj lawm tau txiav thiab sim. Hauv thaj teb, kev teeb tsa tsuas yog qhov teeb meem ntawm kev ntsaws rau hauv ua ntej - txiav cov xaim xaim xaim - tsis muaj splicing, tsis stripping, tsis tu.

MST yog tsim nyob ib ncig ntawm cov cuab yeej sib txuas hardened (xws li OptiTap adapters) uas tiv taus qhov nruj ntawm qhov chaw sab nraum cov nroj tsuag. Nws muaj nyob rau hauv ntau yam configurations: terminated los yog unterminated versions, taw tes-mus rau-point los yog MPO kev sib txuas rau indexing (ntxiv/poob-style) configurations.

3. FDB – Lub thawv Fiber Distribution Box

Nws yog dab tsi

Fiber Distribution Box (FDB) yog phab ntsa -mounted lossis ncej-mounted enclosure siv los txuas optical cables rau cov khoom siv kho qhov muag. Los ntawm cov adapters hauv lub thawv ntim khoom fiber ntau, cov teeb liab kho qhov muag raug xa tawm ntawm fiber ntau jumpers, ua kom pom kev xaim hluav taws xob ua haujlwm. Nws yog ib qho khoom lag luam hauv FTTH thiab FTTB tes hauj lwm, muab lub ntsiab lus nyab xeeb rau kev sib txuas, sib cais, ceg, ncaj- los ntawm, lossis fiber ntau txiav thaum tiv thaiv kev sib txuas ntawm ib puag ncig kev puas tsuaj.

FDB yog tsim los pab txhawb kev sib txuas ntawm optical cables, fibers, thiab patch cords, muab ib tug sleek tsos, neeg siv - tus phooj ywg ua hauj lwm, thiab ib tug ntev kev pab cuam lub neej. Tsis zoo li lub thawv txiav tawm uas ua haujlwm rau ib tus neeg siv (lossis tsawg dua tsib), Fiber Distribution Box yog tsim los muab kev siv fiber ntau rau ntau tus neeg siv, ua rau nws yog qhov tseem ceeb nruab nrab ntawm FTTH tes hauj lwm uas faib cov fiber ntau los ntawm feeder cable rau ntau cov lus qhia mus rau cov neeg siv khoom nkag.

Cov yam ntxwv tseem ceeb

Lub GL-FDB-24D muab ntau lub zog rau hauv ib qho kev sib koom ua ke:

• Dual -chaw layout:Muab faib ua ob ntu - ib qho rau optical cable fusion splicing ntawm lub cable thiab fiber pigtail, thiab lwm qhov rau patch qaum kev twb kev txuas.

• Kev tswj hwm fiber ntau:Fibers tuaj yeem coiled nyob ib ncig ntawm ob lub nplhaib yas, ua kom lub vojvoog dabtsi yog khoov ntau dua 40mm los tiv thaiv cov teeb liab poob.

• Adapter vaj huam sib luag:Ruaj ntseg adapters sib xws nrog SC, LC, thiab FC hom, ua haujlwm yooj yim thiab tiv thaiv kev puas tsuaj rau fibers.

• Cable nkag los ntawm hauv qab:Nkag qhov taw tes tiv thaiv los ntawm tshwj xeeb roj hmab foob.

• Splitter compatibility:Txhawb nqa blockless splitters 1 × 16 thiab 1 × 32, nrog rau 1 × 8 cassette splitters.

Specifications

Nws mus qhov twg

FDBs feem ntau yog siv nyob rau hauv lub tsev txoj kev hauv tsev, stairways, sab nrauv phab ntsa, lossis lwm qhov chaw sib koom hauv zej zog. Lawv ua raws li kev faib cov nodes nyob rau hauv cov txheej txheem nkag ntawm FTTH tes hauj lwm - lub ntsiab lus uas feeder los yog tis cabling yog sib cais thiab xa mus rau ib tug neeg nkag mus rau cov ntsiab lus. GL-FDB-24D yog haum rau ob qho tib si sab hauv tsev thiab sab nraum zoov daim ntaub ntawv, nrog IP65 waterproof tiv thaiv ua rau nws ntseeg tau nyob rau hauv ntau yam tej yam kev mob.

Thaum xaiv FDB

Xaiv ib qho FDB thaum koj xav tau:

• Kev faib tawm ntawm fiber ntau rau ntau tus neeg siv (chaw tsev, tsev nyob hauv zej zog)

• Kev sib xyaw ntawm splicing, splitting, thiab patching nyob rau hauv ib lub thawv

• Phab ntsa lossis ncej mounting sab nraum zoov lossis ib nrab- ib puag ncig sab nraum zoov

Yuav Ua Li Cas Ua Ke Ua Ke: Ib Hom FTTH ODN Txoj Kev

Nyob rau hauv tus qauv FTTH architecture, peb cov cuab yeej ua haujlwm ua ke hauv ib ntu:

1.OLT (chaw ua haujlwm hauv nruab nrab) txuas mus rau ODF, qhov twg feeder fibers raug txiav thiab tswj

2.Feeder cables khiav mus rau qhov chaw faib khoom thiab nkag mus rau hauv FDB, qhov twg cov teeb liab tau muab faib thiab faib rau ntau cov lus qhia

3.Los ntawm FDB, cov xaim xaim xaim txuas mus rau MSTs (lossis lwm cov khoom siv nkag) ntawm cov neeg siv khoom nkag

4.MSTs muab hardened, ua ntej -connectorized ports rau poob cables uas khiav mus rau ONT ntawm cov neeg siv khoom qhov chaw

Tsis yog txhua qhov kev xa tawm xav tau tag nrho peb - tab sis kev nkag siab qhov twg txhua lub cuab yeej koom nrog hauv lub network topology yog qhov tseem ceeb rau kev tsim ODN.

Daim Ntawv Qhia Kev Xaiv: Yam Koj Xav Tau?

Xaus

MST, ODF, thiab FDB ua haujlwm sib txawv thiab ua tiav hauv cov tes hauj lwm fiber ntau optic:

MST muab cov khoom tawv tawv, ua ntej- txuas nkag mus rau - "plug-thiab-play" kev daws teeb meem rau kev xa tawm sai

ODF muab centralized, siab - ceev fiber ntau tswj - "cov hlab ntsha" ntawm lub hauv paus chaw ua hauj lwm los yog cov ntaub ntawv chaw.

FDB ua kom muaj fiber ntau faib rau ntau tus neeg siv nrog kev sib xyaw ua ke, sib cais, thiab patching - "kev sib hloov" ntawm cov khoom noj thiab cov xaim xaim

Xaiv cov cuab yeej tsim nyog rau txheej txheej network yog ib txoj hauv kev zoo tshaj plaws los txo cov sij hawm xa mus, tswj cov nqi, thiab ua kom yooj yim rau kev txij nkawm ntev -. Thaum tsis ntseeg, ua raws li lub network topology: ODF ntawm lub hauv paus, FDB hauv txheej txheej, MST ntawm qhov chaw nkag.
