Product Description
Cov ntsiab lus luv luv
SR812ST(R) yog peb qhov tseeb high-qib ob-tso zis CATV network optical receiver.Lub pre-amplifier txais tag nrho-GaAs MMIC, post-amplifier txais lub GaAs module.Optimized Circuit Court tsim ua ke nrog peb 10 xyoo ntawm kev tsim kev paub, ua kom cov cuab yeej ua tiav cov txiaj ntsig zoo.Kev tswj hwm microprocessor, cov duab digital ntawm qhov tsis muaj, qhov kev debugging engineering yog qhov yooj yim tshwj xeeb.Nws yog cov cuab yeej tseem ceeb los tsim CATV network.
Cov yam ntxwv ua haujlwm
- Siab teb PIN photoelectric hloov raj.
- Optimized circuit tsim, SMT txheej txheem ntau lawm, thiab optimized teeb liab txoj kev ua rau photoelectric teeb liab kis tau tus mob ntau du.
- Tshwj xeeb RF attenuation nti, nrog zoo RF attenuation thiab equilibrium linear, siab raug.
- GaAs amplifier ntaus ntawv, lub zog ob npaug tso zis, nrog kev nce siab thiab qis distortion.
- Tib Chip Microcomputer (SCM) tswj cov cuab yeej ua haujlwm, LCD qhia txog qhov tsis zoo, kev yooj yim thiab kev ua haujlwm zoo, thiab kev ua haujlwm ruaj khov.
- Kev ua tau zoo AGC zoo heev, thaum lub tswv yim kho qhov muag muaj zog yog 9～＋2dBm, cov zis theem tsis hloov, thiab CTB thiab CSO yeej tsis hloov.
- Khaws cov ntaub ntawv kev sib txuas lus sib txuas, tuaj yeem txuas nrog chav kawm Ⅱ network tswj kev teb, thiab nkag mus rau lub network tswj kev tswj hwm.
- Rov qab emission tuaj yeem xaiv hom tawg kom txo qis lub suab nrov convergence thiab txo tus naj npawb ntawm tus neeg txais lub hauv ntej.
Txuas kev kuaj mob
Cov kev tsis sib xws ntawm phau ntawv no raws li kev ntsuas ntawm GY / T 194-2003, thiab kuaj hauv cov xwm txheej hauv qab no.
1. Forward optical txais ib feem: nrog 10km standard optical fiber, passive optical attenuator, thiab standard optical transmitter tsim cov kev sib txuas.Teem 59 PAL-D analog TV channel teeb liab ntawm thaj tsam ntawm 45/87MHz ~ 550MHz nyob rau hauv qhov kev sib txuas tau teev tseg.Xa cov teeb liab digital modulation ntawm qhov ntau ntawm 550MHz ~ 862 / 1003MHz, cov theem teeb liab digital modulation (hauv 8 MHz bandwidth) yog 10dB qis dua qib analog teeb liab.Thaum lub input optical zog ntawm lub optical receiver yog -2dBm, RF tso zis theem yog 108dBμV, nrog 9dB tso zis qaij, ntsuas C/CTB, C/CSO, thiab C/N.
2. Rov qab kho qhov muag kis ib feem: Txuas flatness thiab NPR dynamic ntau yam yog qhov txuas indexes uas yog tsim los ntawm ib tug rov qab kho qhov muag transmitter thiab ib tug rov qab optical receiver.
Nco tseg: Thaum qhov ntsuas qhov tso zis yog qhov kev teeb tsa tag nrho thiab qhov tau txais lub zog kho qhov muag yog -2dBm, cov cuab yeej ua tau raws li qib siab tshaj plaws ntawm qhov txuas txuas.Thaum lub kaw lus configuration txo (uas yog, qhov tseeb kis tau tus mob raws), cov zis theem ntawm cov khoom yuav nce.
Daim ntawv ceeb toom tus phooj ywg: Qhia koj teeb lub teeb liab RF rau 6 ~ 9dB qaij tso zis rau hauv daim ntawv thov kev tsim vaj tsev los txhim kho qhov ntsuas qhov ntsuas tsis tau (hauv qab ntawm lub kaw lus) ntawm cable system.
