Kev Txheeb Xyuas Luv Luv
SR812ST(R) yog peb lub tshuab txais xov tooj cua CATV network tshiab kawg uas muaj ob lub zis siab. Lub pre-amplifier siv tag nrho-GaAs MMIC, thiab lub post-amplifier siv GaAs module. Kev tsim lub voj voog zoo tshaj plaws nrog rau peb 10 xyoo ntawm kev tsim qauv kev tshaj lij, ua rau cov khoom siv ua tiav cov ntsuas kev ua tau zoo. Kev tswj hwm microprocessor, kev tso saib cov kev teeb tsa digital, thiab kev debugging engineering yooj yim heev. Nws yog cov khoom siv tseem ceeb los tsim lub network CATV.
Cov yam ntxwv ntawm kev ua tau zoo
- Cov lus teb siab PIN photoelectric hloov pauv raj.
- Kev tsim qauv hluav taws xob zoo tshaj plaws, kev tsim cov txheej txheem SMT, thiab txoj kev teeb liab zoo tshaj plaws ua rau kev xa cov teeb liab photoelectric du dua.
- Cov nti RF attenuation tshwj xeeb, nrog RF attenuation zoo thiab sib npaug linear, qhov tseeb siab.
- GaAs amplifier ntaus ntawv, lub zog tso zis ob npaug, nrog qhov nce siab thiab qis distortion.
- Cov khoom siv tswj hwm ib leeg Chip Microcomputer (SCM) ua haujlwm, LCD tso saib cov kev teeb tsa, kev yooj yim thiab kev ua haujlwm intuitive, thiab kev ua haujlwm ruaj khov.
- Kev ua tau zoo AGC zoo heev, thaum lub zog fais fab optical input yog -9 ~ ＋2dBm, qib tso zis tsis hloov pauv, thiab CTB thiab CSO yeej tsis hloov pauv.
- Kev sib txuas lus cov ntaub ntawv khaws cia, tuaj yeem txuas nrog chav kawm Ⅱ network management responder, thiab nkag mus rau lub network management system.
- Kev xa rov qab tuaj yeem xaiv hom tawg kom txo qhov kev sib sau ua suab nrov thiab txo tus lej txais pem hauv ntej.
Cov Cai ntawm Kev Ntsuas Txuas
Cov kev ntsuas ntawm phau ntawv qhia no raws li txoj kev ntsuas ntawm GY / T 194-2003
1. Kev txais optical rau pem hauv ntej: nrog 10km tus qauv optical fiber, passive optical attenuator, thiab tus qauv optical transmitter tsim qhov txuas sim. Teem 59 PAL-D analog TV channel teeb liab ntawm qhov ntau ntawm 45/87MHz ~ 550MHz nyob rau hauv qhov txuas poob teev tseg. Xa cov teeb liab digital modulation ntawm qhov ntau ntawm 550MHz ~ 862/1003MHz, qib teeb liab digital modulation (hauv 8 MHz bandwidth) yog 10dB qis dua qib analog teeb liab. Thaum lub zog nkag optical ntawm lub optical receiver yog -2dBm, qib tso zis RF yog 108dBμV, nrog 9dB tso zis qaij, ntsuas C / CTB, C / CSO, thiab C / N.
2. Qhov rov qab optical transmit ib feem: Link flatness thiab NPR dynamic range yog cov txuas indexes uas yog tsim los ntawm ib qho backward optical transmitter thiab ib qho backward optical receiver.
Lus Cim: Thaum qib tso zis ntsuas yog qhov system tag nrho kev teeb tsa thiab lub zog kho qhov muag tau txais yog -2dBm, cov khoom siv ua tau raws li qib tso zis siab tshaj plaws ntawm qhov txuas txuas. Thaum qhov kev teeb tsa system txo qis (uas yog, cov channel kis tau tiag tiag txo qis), qib tso zis ntawm cov khoom siv yuav raug nce ntxiv.
Daim Ntawv Ceeb Toom Phooj Ywg: Xav kom koj teeb tsa lub teeb liab RF rau 6 ~ 9dB tilt tso zis hauv daim ntawv thov engineering kom txhim kho cov ntsuas nonlinear (hauv qab node) ntawm lub kaw lus cable.
