SR4020AW Optical receiver ndi cholandila chapanyumba chokhala ndi ma fiber optical monga cholinga chake chachikulu. Ndi yoyenera kwa FTTH (fiber to the home) network CHIKWANGWANI olembetsa kupeza materminal, kuwapangitsa analogi kapena digito chizindikiro kulowa kunyumba. Makinawa amagwiritsa ntchito ma photodetectors otsika mphamvu, ma GaAs, ndi ukadaulo wa AGC wowoneka bwino kuti akwaniritse zosowa zolandirira za CATV. Chipangizochi chitha kukulitsa WDM ndikukwaniritsa kusewera katatu.
Makhalidwe Antchito
- Chipolopolo cha aluminiyumu yapamwamba kwambiri yokhala ndi kutentha kwabwino.
- RF njira yodzaza ndi GaAs otsika phokoso amplifier dera. Chizindikiro cha digito chimakhutiritsa -18dBm kulandira pang'ono ndi -10dBm kulandira chizindikiro cha analogi osachepera.
- Ndi mawonekedwe a optic AGC (mtundu wa AGC wasinthidwa makonda).
- Mapangidwe amphamvu otsika, pogwiritsa ntchito magetsi osinthika kwambiri kuti atsimikizire kudalirika kwakukulu komanso kukhazikika kwamphamvu kwamagetsi. Mphamvu yonse yogwiritsa ntchito mphamvu ndi yochepera 1W, yokhala ndi dera lozindikira kuwala.
- Zida zotetezera mphezi zamitundu yambiri (TVS transient suppression diode), ndi njira zotetezera mphezi ndizolimba kuti zitsimikizire kuti zida zikuyenda bwino.
- WDM yomangidwa mkati imatha kuzindikira nyumba yokhala ndi fiber imodzi (1490/1310/1550nm) ma tri-network convergence application.
- Wopanga-wopanga wodzipatula, wolowera kuti akwaniritse kudzipatula kwa 1490/1310nm.
- Kupeza komwe kumatuluka kumasinthidwa pamanja (0 ~ 18dB) ndipo mulingo wotuluka ndi> 80dBuV.
- SC/APC kapena FC/APC kapena zolumikizira mwamakonda kuwala, metric kapena imperial RF interfaces.
- Ikhoza kuzindikira njira yamagetsi yoperekera chakudya.
- Zotulutsa imodzi kapena ziwiri ndizosankha
Langizo ndi Chidziwitso:
Mayesero: 59 PAL-D ma analogi kanema wawayilesi siginecha pa 550 MHz ma frequency osiyanasiyana, mu osiyanasiyana 550 MHz mpaka 862 MHz, pansi ulalo kutayika kwapadera
Chizindikiro chosinthira digito chimaperekedwa mkati mwa kuchuluka kwa kuchuluka, mulingo wa siginecha yosinthira digito (mkati mwa bandwidth ya 8 MHz) ndi 10 dB kutsika kuposa kuchuluka kwa chonyamulira cha siginecha ya analogi, ndipo mphamvu yowunikira yolandila ndi 0dBm, yoyezera C. /N, CTB, CSO.
