LUB 719
OR719 Sab nraum zoov Bi-directional Plaub Outputs Optical Receiver
Nta
◆High responsibility PIN photoelectric hloov raj.
◆ Precision detection Circuit Court muaj peev xwm tiag-lub sij hawm tso saib lub zog tso zis los ntawm LED teeb lossis lub raj digital kom raug.
◆ Ua kom zoo rau kev tsim hluav taws xob, SMT + module amplifier classic circuit photoelectricity teeb liab kis tau yooj yim dua.
◆ Fais fab tso zis ob npaug, siab nce, tsis tshua muaj distortion, compact qauv, yooj yim installation, yog thawj-xaiv khoom ntawm FTTB CATV network.
◆ Zoo heev kho qhov muag AGC tswj cov txheej txheem, thaum lub tswv yim kho qhov muag fais fab ntau yam yog -7 ~ + 2dBm, cov zis theem, CTB thiab CSO yeej tsis hloov.
