ZBR1001JL lub vev xaib kho qhov muag tau txais yog qhov kawg 1GHz FTTB lub qhov muag txais. Nrog rau ntau qhov tau txais lub zog kho qhov muag, cov qib tsim tawm siab thiab kev siv hluav taws xob tsawg. Nws yog cov khoom siv zoo tshaj plaws los tsim kom muaj qhov siab-NGB network.

2. Kev Ua Yam ntxwv

Cov txheej txheem kev tswj kom zoo dua qub AGC tswj hwm, thaum lub tswv yim optical fais fab yog -9+ +2dBm, qib tso zis, CTB thiab CSO yeej tsis hloov;

■ Downlink ua hauj lwm zaus ncua ntev txog 1GHz, RF amplifier part adopts qhov kev ua haujlwm siab qis zog noj GaAs nti, qib siab tso tawm ntau dua mus txog 112dBuv;

EQ thiab ATT ob leeg siv lub tshuab hluav taws xob tswj kev lag luam, ua rau kev tswj ntau qhov tseeb, ua haujlwm yooj yim dua;

■ Ua-hauv lub teb chaws tus qauv II class network tswj teb, pab txhawb cov tswj chaw taws teeb network (yeem);

Act Cov qauv kev cog lus, kev teeb tsa yooj yim, yog thawj qhov khoom siv xaiv ntawm FTTB CATV network;

Ua-hauv kev cia siab rau kev siv hluav taws xob tsawg, thiab xaiv cov khoom siv fais fab sab nraud;

6. Huv si thiab kho cov qauv ntawm cov optical fiber active txuas

Ntau lub sijhawm, peb ua kom yuam kev poob qis ntawm lub zog kho qhov muag lossis qhov txo qis ntawm cov khoom txais tawm ntawm cov khoom tso tawm uas yog cov khoom siv tsis raug, tab sis qhov tseeb nws yuav tshwm sim los ntawm qhov tsis sib txuas ntawm cov kab hluav taws xob kho qhov muag lossis qhov kho qhov muag fiber tau ua rau muaj kuab paug los ntawm hmoov av lossis av.

Tam sim no qhia qee qhov kev nyiam huv thiab kev saib xyuas ntawm cov roj carbon fiber txuas txuas.

1. ua zoo hau ntswj tawm ntawm cov qhov kho qhov muag fiber nquag txuas ntawm lub adapter. Optical fiber active txuas yuav tsum tsis txhob taw ntawm tib neeg lub cev lossis qhov muag liab qab kom tsis txhob raug mob raug mob.

2. Ntxuav nrog qhov zoo zoo lo so ntawv lossis ntaub ntawv kho mob degrease cawv paj rwb. Yog tias siv cov tshuaj kho mob degrease cawv paj rwb, tseem yuav tsum tau tos 1 ~ 2 feeb tom qab ntxuav tas, cia cov khoom sib txuas ua kom qhuav hauv huab cua.

3.Cov khoom siv kho qhov muag tau muaj fiber ntau txuas nrog yuav tsum txuas nrog lub ntsuas hluav taws xob ntsuas kom ntsuas cov khoom siv hluav taws xob kom paub meej tias nws tau tu.

4.Thaum ntsia hlau rau cov khoom siv kho qhov muag ua kom zoo txuas rov qab rau lub adapter, yuav tsum pom tias lub zog ua kom tsim nyog kom tsis txhob muaj cov raj ceramic hauv qhov hluav taws xob tawg.

5.Yog hais tias cov zis hluav taws xob tsis zoo tsis yog li ib txwm muaj tom qab tu, yuav tsum tau ntswj tawm ntawm lub adapter thiab tu lub txuas txuas ntxiv. Yog tias lub teeb ci fais fab tseem qis tom qab ntxuav, lub tshuab yoog kuj tuaj yeem muaj kuab paug, ntxuav nws. (Nco tseg: Ua tib zoo saib thaum ntsia hlau tawm ntawm lub adapter kom tsis txhob raug mob sab hauv).

6. Siv lub tshuab ua kom muaj huab cua nyob sab hauv lossis huab cua cawv kom khov kho kom huv rau lub adapter. Thaum siv lub tshuab cua nrawm, qhov sib txuas ntawm lub tshuab kaw huab cua yuav tsum ua lub hom phiaj zoo li lub raj xa dej ntawm lub adapter, ntxuav lub raj ceramic nrog cov huab cua compressed. Thaum siv degrease cawv paj rwb bar, ua tib zoo nchuav cov cawv cawv hauv qab rau hauv lub raj tshuaj tua kab kom huv si. Cov kev taw qhia ntxig yuav tsum zoo ib yam, txwv tsis pub tuaj yeem ncav cuag cov nyhuv tu uas tsim nyog.

7. Cov kev pab cuam tom qab muag tas

1.Peb cov lus cog tseg: Muaj kev tiv thaiv dawb rau kaum peb lub hlis (Cia lub sijhawm Hoobkas ntawm cov khoom lag luam daim ntawv pov thawj khoom raws li hnub pib) Lub sijhawm txuas ntxiv warranty raws li cov lus pom zoo muab. Peb lub luag haujlwm rau kev tu lub neej. Yog tias cov khoom siv txhaum yog tshwm sim los ntawm cov neeg siv ua haujlwm tsis raug cai lossis cov chaw nyob tsis raug cai, peb yuav lub luag haujlwm saib xyuas tab sis thov kom cov khoom tsim nyog.

2.Thaum cov cuab yeej rhuav tshem, hu rau peb cov txheej txheem kev pab cuam sai 8613675891280

3.Qhov chaw kho cov khoom txhaum thiaj yuav tsum ua haujlwm los ntawm cov kws tshaj lij kom tsis txhob muaj kev puas tsuaj loj.

Daim ntawv ceeb toom tshwj xeeb: Yog tias cov khoom tau raug tswj los ntawm cov neeg siv, peb yuav tsis lav lub luag haujlwm kho dawb. Peb yuav nug kom tsim nyog tus nqi thiab cov khoom siv tus nqi.
