Khoom Description
Qhov no FTTB AGC CATV Optical Receiver yog tsim los ua lub hwj chim qis kho qhov muag tau txais cov cuab yeej rau kev hloov kho "Fiber To The Building" (FTTB). Cov cuab yeej no siv cov duab kho qhov muag pom kev siab siab- raj, lub suab qis gallium arsenide amplifier nti hauv preposition thiab gallium arsenide thawb- rub amplifier Circuit Court nyob rau theem kawg uas muab cov zis ntau tshaj 2 × 100dBuV. Tsis tas li ntawd, siab - xob laim- tiv thaiv kev tiv thaiv - surge linear fais fab mov, AGC tsis siv neeg tso zis theem tswj thiab digital zaub ntawm optical txais thiab RF tso zis theem tau teeb tsa hauv cov cuab yeej no. Vim muaj kev ua tau zoo ntawm cov khoom tseem ceeb thiab zoo-tsim Circuit Court, nws lav qhov kev ua tau zoo thiab kev ntseeg tau zoo dua ntawm cov khoom tiav no.
Cov yam ntxwv ua haujlwm
Ntau dua 0.9A / W siab teb PIN photoelectric hloov raj.
Kab optimization tsim, SMT txheej txheem ntau lawm, optimize tag nrho cov teeb liab channel, photoelectric teeb liab kis tau tus mob ntau smoothly.
GaAs amplifier qhov chaw, lub hwj chim multiplier tso zis, siab nce, tsawg distortion.
Tau txais optical zog ntau yam -12 ~ +3dBm ,
Cov yam ntxwv AGC zoo heev, lub tswv yim kho qhov muag lub zog -8 -+2dBm, cov zis theem tseem tsis hloov, CTB, CS0 yeej tsis hloov.
Configured nrog lub teb chaws tus txheej txheem network tswj transponder, tuaj yeem nkag tau yooj yim hauv lub network tswj system.Configured nrog lub teb chaws tus qauv network tswj transponder, tuaj yeem nkag tau yooj yim hauv kev tswj hwm network.
