MDU Fiber Ua tiav Cabling Guide - Kev Paub - Evolux Fiber

MDU yog dab tsi? (Lub tswv yim)

MDU sawv cev rau Multi-Dwelling Unit. Hauv kev lag luam hauv xov tooj thiab kev sib txuas lus, lo lus no hais txog lub tsev nrog ntau tsev neeg ywj pheej. Cov piv txwv muaj xws li cov tsev tsev, cov tsev kawm ntawv cov tsev so, tsev so, thiab cov tsev ua haujlwm.

Cov ntsiab lus MDU fiber ntau lossis MDU fiber ntau optic hais txog kev xa tawm fiber ntau-rau--tsev (FTTH) tes hauj lwm rau ntau- tsev tsev. Qhov no yog ib txoj kev xa tawm txawv dua li kev xa mus rau cov tsev nyob (SDU, Ib Leeg-Lub Tsev Nyob):

Kev sib piv	SDU	MDU
Cov neeg siv kev faib tawm	Tshaj tawm, ib tsev neeg ib lub qauv	Concentrated, ntau units ib lub tsev
Kev siv Cable	Dedicated cable rau ib tsev neeg	Sib koom caj qaum, branched te
Txoj kev sib cais	Feem ntau sab nraum zoov	Tiered splitting hauv lub tsev
Cable Complexity	Yooj yim	Yuav tsum tau ua tib zoo npaj

Tau txais lub tswv yim tseem ceeb ntawm MDU yog dab tsi hauv kev sib txuas lus, tam sim no peb muaj kev nkag siab zoo dua ntawm kev xa ib qho kev daws teeb meem MDU fiber ntau.

Cov lus qhia no tuaj yeem daws teeb meem dab tsi rau koj?

Qhov no yog ib qho kev qhia ua haujlwm fiber ntau MDU. Txawm hais tias koj yog tus kws tshaj lij network npaj MDU fiber optic project / tus neeg yuav khoom uas yuav tsum nkag siab lub ntsiab lus ntawm MDU hauv xov tooj / tus thawj tswj vaj tsev uas xav nkag siab tias MDU sawv cev rau hauv xov tooj.

Los yog tsuas yog ib tus neeg nyiam tshaj lij uas xav nkag siab cov ntsiab lus ntawm MDU cable cabling, koj yuav pom cov ntaub ntawv tseem ceeb MDU qhov project ntawm no.

Kuv yuav sivEvolux Fiber cov khoomua piv txwv vim tias peb cov khoom lag luam npog cov khoom siv tseem ceeb rau MDU cabling: fiber ntau optic connectors, thaj cords, pigtails, PLC splitters, davhlau ya nyob twg thawv, thiab adapters-cov no yog cov feem ntau siv passive Cheebtsam nyob rau hauv MDU fiber ntau installation.

Cov tswv yim dab tsi yuav tsum tau siv rau ntau qhov sib txawv ntawm MDUs?

Kev nkag siab txog qhov loj ntawm koj MDU yog qhov tseem ceeb ua ntej peb tuaj yeem pib siv lub tswv yim, vim tias txoj kev xa tawm txawv. Qhov no txiav txim seb muaj pes tsawg tus splitters, lub thawv davhlau ya nyob twg, thiab fiber ntau optic cabling koj xav tau. MDU telecom tej yaam num tau muab faib ua peb hom raws li tus naj npawb ntawm cov plag tsev thiab tsev neeg:

MDU hom	Pem teb	Chav tsev	Kabling Strategy	Pom zoo Splitting Architecture
Tsawg-Rise MDU	Tsawg dua lossis sib npaug li 3 plag tsev	Tsawg dua lossis sib npaug li 12 units	Centralized, khoom siv sab nraum lub tsev	Tib -theem 1:16
Nruab nrab -Rise MDU	4-10 pem teb	12-128 units	Distributed, khoom siv chav + pem teb terminals	Ob -theem 1:8 × 1:8
Siab -Rise MDU	>10 pem teb	>128 units	Tiered, ntau chav faib khoom	Ob -theem 1:16 × 1:8

MDU Fiber network zoo li cas?

Nov yog daim duab qhia los pab koj nkag siab: Ua tiav MDU fiber optic network muaj plaub thaj chaw, txuas ntxiv los ntawm tus neeg teb xov tooj kawg mus rau tus tswv tsev kawg:

MDU FTTH Cbaling System Architecture

Txoj hauj lwm ntawm MDU fiber ntau installation yog txuas rau plaub thaj chaw siv cov khoom tsim nyog.

Yuav ua li cas configuration yog xav tau rau lub ntsiab khoom siv chav tsev?

Koj puas nco qab qhov loj ntawm koj MDU? Tom qab ntawd peb tuaj yeem pib nkag siab yuav ua li cas teeb tsa cov khoom siv tseem ceeb hauv chav. Chav tsev cov cuab yeej siv tseem ceeb yog lub luag haujlwm tseem ceeb rau kev txiav tawm sab nraud fiber ntau optic, lub ntsiab routing, thiab kev faib tawm, cuam tshuam rau tag nrho cov peev txheej network thiab scalability. Kuv tau teev cov khoom tsim nyog ncaj qha rau koj siv:

Evolux Fiber Recommended Equipment Configuration

Hom khoom siv	Specifications	Daim ntawv thov	Vim li cas thiaj xaiv qhov no
Khib -Mount ODF	4U, 144/288-core	Nruab nrab -MdU loj (60-200 units)	Muaj peev xwm, nthuav dav yooj yim
Swb-Tawm ODF	2U, 48/96-core	Medium MDU (24-60 units)	Kev ua haujlwm yooj yim, tus nqi zoo
Kho ODF	2U, 48-core SC / 96-core LC	Small MDU (<24 units)	Cov qauv yooj yim, tus nqi qis
Phab ntsa-Mount Fiber Box	1U/2U, 12/24/48-chaw nres nkoj	Qhov chaw- txwv qhov xwm txheej	Tsis xav tau qhov chaw hauv pem teb

ODF (Optical Distribution Frame) yog ib qho tseem ceeb ntawm cov cuab yeej siv hauv chav tsim khoom. Evolux's ODF thaj vaj huam sib luag muaj ob peb yam tseem ceeb: zoo nkauj zoo nkauj, tsim nyog thaiv, yooj yim mus nrhiav, thiab yooj yim installation-cov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau kev kho tom qab.

Ib qho piv txwv tshwj xeeb los ntawm Evolux: Cov txheej txheem teeb tsa rau 80- chav tsev nyob nruab nrab-nce

Yog tias koj qhov project tseem yog lub tsev 10-zaj dab neeg nrog 8 units hauv ib pem teb, tag nrho 80 units, ces koj chav tsev khoom tseem ceeb tuaj yeem teeb tsa raws li hauv qab no:

Main Equipment Room Configuration

Cov npe khoom siv hauv kev daws teeb meem:·

4U 288-core khib-mount ODF × 1
1:8 LGX PLC splitter × 4 (2 nyob rau hauv kev siv, 2 ntawm standby)
SC/APC pigtail 1m × 96
SC / APC thaj qaum 2m × 80
1U kab rov tav cable tswj khib × 3

PLC optical splitter yog dab tsi? Nws siv li cas hauv MDU?

Cov neeg ua haujlwm tsuas yog muab 1-2 fibers optical (xws li 1-2 PON chaw nres nkoj) lossis qee cov fibers tsawg, tab sis peb yuav tsum txuas rau kaum lossis ntau pua tsev neeg. Nyob rau hauv cov ntaub ntawv no, ib tug optical splitter yog siv los daws qhov teeb meem no los ntawm "tig ib tug mus rau hauv ntau." Lub PLC optical splitter siv lub hauv paus ntsiab lus ntawm kev kho qhov muag waveguide rau "kev sib cais" ib lub teeb ntawm lub teeb rau hauv ntau lub teeb. Piv txwv li, 1: 8 splitter muaj 1 input thiab 8 outputs, nrog rau txhua qhov tso zis muaj kwv yees li 1/8 ntawm lub teeb liab thawj lub zog.

Cov xwm txheej sib txawv ntawm daim ntawv thov yuav tsum tau siv cov splitters nrog cov khoom siv sib xws:

Hom pob	Cov yam ntxwv loj	Qhov twg rau nruab	Thaum siv
Liab Fiber	Tsawg tshaj plaws	Yuav tsum muaj kev tiv thaiv ntxiv	Kev cai splicing scenarios
Mini Hlau Tube	3 × 40mm	Sab hauv lub thawv terminal	Thawj qhov kev xaiv rau pem teb splitting
ABS Box	100 × 80 × 10mm	Standalone installation	Sab nraum zoov lossis qhov chaw dav
LGX Cassette	Standard module	Hauv ODF khib	Cov khoom siv tseem ceeb hauv chav splitting
Txuas - hauv daim npav	Daim npav - loj	Distribution box slots	Pem teb faib lub thawv

Splitting Ratio Reference Table:

Split Ratio	Theoretical Poob	Loss tiag	Daim ntawv thov
1:2	3.0dB ua	3.2-3.8 dB	Cascade ua ntej-theem
1:4	6.0dB ib	6.5-7.2 dB	Me me qis-nce MDU
1:8	9.0db ua	9.5-10.5 dB	Medium MDU, feem ntau
1:16	12.0 dB	12.5-13.5 dB	Centralized splitting
1:32	15.0 dB	15.5-17.0 dB	Loj MDU thawj splitting
1:64	18.0 dB	18.5-20.5 dB	Ultra- cov xwm txheej ceev heev

Koj puas yuav tsum xaiv ib qho -theem lossis ob-theem splitting?

Ib leeg-theem splitting yuav muab ib tug loj splitter (piv txwv li, 1:32) nyob rau hauv qab daus, ncaj qha faib cov fiber rau txhua tsev neeg mus rau 32 txoj kev. Txoj hauv kev no yog qhov yooj yim hauv cov qauv thiab muaj cov ntsiab lus sib cais tsawg dua, tab sis cov cabling yog qhov nyuaj vim muaj ntau cov fiber ntau optic cables.

Ob -theem splitter yuav tsum tso ib tug 1: 8 splitter rau hauv qab daus, thiab ces lwm 1: 8 splitter nyob rau hauv txhua pem teb, zoo pab 8 x 8=64 tsev neeg. Txoj kev no yuav tsum tau siv fiber ntau optic cables tsawg dua thiab hloov tau yooj yim dua, tab sis qhov sib cais ntxiv ua rau cov fiber ntau poob los ntawm kwv yees li 10dB.

Two-Level Splitting Architecture

Rau MDUs uas muaj ntau tshaj 30 tsev neeg, peb pom zoo kom ob-theem splitting. Qhov no yog txoj hauv kev tseem ceeb rau MDU fiber ntau installation.

Yuav ua li cas xaiv lub thawv davhlau ya nyob twg?

Hauv pem teb thaiv qhov chaw yog qhov "kev sib tshuam taw tes" ntawm ntsug qaum kho qhov muag cables thiab kab rov tav kab rov tav - cov kab hluav taws xob kho qhov muag nyob rau hauv riser "av" ntawm no, thiab tom qab ntawd ceg mus rau ntau qhov kev kho qhov muag txuas mus rau txhua tsev neeg.
