Cov ntsiab lus luv luv
SR4020AW optical receiver yog lub tsev kho qhov muag receiver nrog optical fiber nkag raws li nws lub hom phiaj kawg. Nws yog qhov tsim nyog rau FTTH (fiber rau hauv tsev) network fiber ntau cov neeg siv khoom nkag mus rau cov chaw nres tsheb, ua kom muaj cov cim analog lossis digital nkag mus rau hauv tsev. Lub tshuab siv hluav taws xob photodetectors tsawg, GaAs, thiab kho qhov muag AGC thev naus laus zis kom ua tau raws li fiber ntau-rau-lub tsev CATV txais tos xav tau. Cov cuab yeej no tuaj yeem nce WDM thiab ua tiav triple ua si.
Cov yam ntxwv ua haujlwm
- High-quality aluminium profile plhaub nrog zoo cua sov dissipation.
- RF channel tag nrho GaAs tsis tshua muaj suab nrov amplifier Circuit Court. Lub teeb liab digital txaus siab -18dBm txais tos ntawm qhov tsawg kawg nkaus thiab -10dBm txais tos ntawm lub teeb liab analog ntawm qhov tsawg kawg nkaus.
- Nrog optic input AGC (AGC ntau yog customized).
- Kev tsim hluav taws xob tsawg, siv cov khoom siv hluav taws xob hloov hluav taws xob kom muaj kev ntseeg siab thiab ruaj khov siab ntawm cov khoom siv hluav taws xob. Kev siv hluav taws xob tag nrho yog tsawg dua 1W, nrog lub teeb pom kev zoo.
- Cov cuab yeej tiv thaiv hluav taws xob ntau theem (TVS ntu ntu tiv thaiv diodes), thiab cov txheej txheem tiv thaiv hluav taws xob nruj kom ntseeg tau tias cov khoom siv ua haujlwm nyab xeeb.
- Ua-hauv WDM tuaj yeem paub ib leeg-fiber tsev (1490/1310/1550nm) tri-network convergence daim ntaub ntawv.
- Built-in optical isolator, tawm tswv yim kom ua tiav 1490/1310nm cais.
- Cov zis nce yog manually adjustable (0 ~ 18dB) thiab cov zis theem yog> 80dBuV.
- SC / APC lossis FC / APC lossis kev cai kho qhov muag txuas, metric lossis imperial RF cuam tshuam.
- Nws tuaj yeem paub txog hom kev siv hluav taws xob ntawm cov khoom tso tawm.
- Ib qho lossis ob qhov tso zis yog xaiv tau
Tswv yim thiab ceeb toom:
Cov xwm txheej xeem: 59 PAL-D analog TV channel teeb liab ntawm 550 MHz zaus ntau yam, nyob rau hauv thaj tsam ntawm 550 MHz txog 862 MHz, raws li cov cai txuas tsis tau
Cov teeb liab hloov pauv digital kis tau nyob rau hauv tus nqi ntau, theem ntawm cov teeb liab hloov pauv digital (nyob rau hauv 8 MHz bandwidth) yog 10 dB qis dua tus neeg nqa khoom theem ntawm cov teeb liab analog, thiab cov khoom siv hluav taws xob optical input optical zog yog 0dBm, ntsuas C /N, CTB, CSO.
