Khoom Taw qhia

HFC Optical Node

SR814 / SR814R yog ahigh-qib plaub-txoj kev sab nraum zoov HFC Optical Node. Nws yog cov khoom siv tseem ceeb los tsim CATV network.

Cov yam ntxwv ntawm kev ua tau zoo

Siab teb tus PIN photoelectric hloov raj.

Optimized Circuit Court tsim, SMT cov txheej txheem ntau lawm, optimized teeb liab txoj kev, ua rau

photoelectric teeb liab kis ntau du.

Tshwj xeeb RF attenuation chip, nrog zoo RF attenuation thiab equilibrium linear, muaj qhov raug.

GaAs amplifier ntaus ntawv, lub zog tso tawm ob zaug, nrog kev nce siab thiab qes dua.

Ib Leeg Microcomputer (SCM) tswj cov cuab yeej ua haujlwm, LCD tso saib cov tsis,

yooj yim thiab intuitive lag luam, thiab ruaj khov ua tau zoo.

Kev ua haujlwm zoo rau AGC, thaum lub tswv yim optical optical zog ntau yog power9 ～＋ 2dBm, cov zis

qib kom tsis hloov, CTB thiab CSO yeej tsis hloov.

Cov ntaub ntawv sib txuas lus sib txuas, tuaj yeem txuas nrog chav kawm Ⅱ kev tswj hwm network

tus neeg teb, nkag mus rau cov kev tswj hwm network.

Rov qab taug kev tuaj yeem xaiv hom tawg ntho ua kom txo qis lub suab sib tshuam thiab zoo heev

nce kev ua tau zoo thiab kev cia siab ntawm lub lag luam network.
