SR812ST(R) ndiye cholandirira chathu chaposachedwa kwambiri cha CATV network optical receiver. Pre-amplifier imatenga Full-GaAs MMIC, post-amplifier imatenga gawo la GaAs. Mapangidwe okhathamiritsa ozungulira ophatikizidwa ndi zaka 10 za luso laukadaulo, zipangitsa kuti zidazo zizigwira bwino ntchito. Kuwongolera kwa Microprocessor, kuwonetsa kwa digito kwa magawo, kukonza zolakwika zaukadaulo ndikosavuta kwambiri. Ndi chida chachikulu chopangira netiweki ya CATV.
Makhalidwe Antchito
- Kuyankha kwakukulu kwa PIN yosinthira zithunzi zamagetsi.
- Mawonekedwe okhathamiritsa ozungulira, kupanga njira za SMT, ndi njira yokongoletsedwera yama siginecha imapangitsa kuti kufalitsa kwa siginecha yazithunzi kukhala kosavuta.
- Specialized RF attenuation chip, yokhala ndi RF attenuation yabwino komanso milingo yofananira, yolondola kwambiri.
- Chida cha amplifier cha GaAs, mphamvu zotulutsa kawiri, zopindula kwambiri komanso zosokoneza pang'ono.
- Chida chowongolera cha Single Chip Microcomputer (SCM) chikugwira ntchito, LCD imawonetsa magawo, kusavuta komanso kugwira ntchito mwanzeru, komanso magwiridwe antchito okhazikika.
- Kuchita bwino kwambiri kwa AGC, pamene mphamvu yamagetsi yolowetsamo ndi －9～＋2dBm, mulingo wotulutsa umakhala wosasinthika, ndipo CTB ndi CSO kwenikweni sizisintha.
- Mawonekedwe ochezera a data osungidwa, amatha kulumikizana ndi kalasi Ⅱ woyankha kasamalidwe ka netiweki, komanso mwayi wowongolera maukonde.
- Kubwereranso kumatha kusankha njira yophulika kuti muchepetse kusinthika kwaphokoso ndikuchepetsa nambala yolandila kutsogolo.
Mikhalidwe Yoyesera Yamalumikizidwe
Magawo aumisiri a bukhuli molingana ndi njira yoyezera ya GY/T 194-2003
1. Gawo la Forward Optical kulandira gawo: ndi 10km standard optical fiber, passive optical attenuator, ndi standard optical transmitter anapanga ulalo woyesera. Khazikitsani siginecha ya 59 PAL-D ya analogi ya TV pamtunda wa 45/87MHz ~ 550MHz pansi pa kutayika kwa ulalo komwe kwatchulidwa. Tumizani chizindikiro chosinthira digito pamitundu ingapo ya 550MHz ~ 862/1003MHz, mulingo wamasinthidwe a digito (mu bandwidth 8 MHz) ndi 10dB kutsika kuposa mulingo wa chonyamulira ma analogi. Mphamvu ya kuwala ikakhala -2dBm, mulingo wa RF ndi 108dBμV, wokhala ndi 9dB yopendekera, yesani C/CTB, C/CSO, ndi C/N.
2. Gawo lotumiza la backward Optical transmit: Link flatness ndi NPR dynamic range ndi maulalo omwe amapangidwa ndi chowulutsa chakumbuyo ndi cholandila chakumbuyo.
Zindikirani: Pamene mlingo wotulutsidwa ndi dongosolo lonse la dongosolo ndipo mphamvu yolandira kuwala ndi -2dBm, zipangizozo zimakumana ndi mlingo waukulu wotuluka wa index index. Pamene kasinthidwe kachitidwe kamachepetsa (ndiko kuti, njira zopatsirana zenizeni zimachepetsa), mlingo wotuluka wa zipangizo udzawonjezeka.
Chidziwitso Chaubwenzi: Muwonetseni kuti muyike chizindikiro cha RF ku 6 ~ 9dB yopendekeka munjira yogwiritsira ntchito uinjiniya kuti muwongolere index yopanda mzere (pansi pa node) ya chingwe.
