CATV OPTICAL NODE

SR1002 yog peb cov chav kawm qib siab hauv CATV lub vev xaib kho qhov muag txais, nrog ntau lub zog tau txais cov khoom siv hluav taws xob zoo, cov zis theem siab thiab kev siv hluav taws xob tsawg. Nws yog cov khoom siv zoo tshaj plaws los tsim kom muaj qhov kev ua tau zoo NGB network.

Qhov no catv kho qhov muag pom adopts GaAs MMIC ua kom nrov kho module. Kev tsim kho hluav taws xob zoo tsim, txuas nrog lub tuam txhab 10 xyoo tsim kev paub, ua rau cov cuab yeej ua tiav cov ntsuas kev ua tau zoo. Cov tsis zoo yuav raug tso tawm los ntawm ib leeg-nti los ua kom qhov kev ua haujlwm debug tau yooj yim dua. Nws yog qhov kev xaiv zoo tshaj plaws rau CATV network

Nta ntawmCatv Optical Node

1.Thaum cov tswv yim tawm tswv yim fais fab ntau yog -9 ~ d 2dBm, cov zis tawm, CTB thiab CSO yog qhov tsis hloov. AGC tswj kev tswj kom haum yog qhov kho tau.

2. Qhov downlink ua hauj lwm zaus raug txuas rau 1 GHz. RF amplifier part adopts qhov kev ua haujlwm siab thiab qis zog noj GaAs nti. Qib tsim ntau tshaj plaws yog nce mus txog 106 dBuv.

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

4. Nws tau tsim hauv lub teb chaws tus qauv chav kawm II kev tswj hwm network thauj khoom. Thiab nws txhawb cov chaw taws teeb network tswj hwm (yeem).

5. Nrog cov qauv compact thiab yooj yim installation, nws yog thawj qhov kev xaiv ntawm FTTB CATV khoom siv network.
