Cov Khoom Siv Fiber Transponder, SA120IE
Kev Piav Qhia Luv:
Cov lus qhia tshwj xeeb ntawm cov khoom no suav nrog DOCSIS® thiab EuroDOCSIS® 3.0 versions ntawm Embedded Cable Modem Module series ntawm cov khoom. Throughput daim ntawv no, nws yuav raug xa mus rau SA120IE. Lub SA120IE yog kub hardened rau kev koom ua ke nrog lwm cov khoom uas yuav tsum tau ua haujlwm hauv sab nraum zoov lossis qhov kub heev. Raws li Full Band Capture (FBC) function, SA120IE tsis yog tsuas yog Cable Modem, tab sis nws kuj tuaj yeem siv ua Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink yog qhov yuav tsum tau ua thiab daim ntawv thov tshwj xeeb. Peb lub qhov PCB tau muab nyob ib puag ncig CPU, yog li ntawd lub heatsinking bracket lossis cov khoom siv zoo sib xws tuaj yeem txuas rau PCB, kom hloov cov cua sov tsim tawm ntawm CPU thiab mus rau lub tsev thiab ib puag ncig.

Kev thaiv qhov system
Tus Saib Xyuas Sab Nraud
Ib tug neeg saib xyuas sab nraud siv los xyuas kom meej tias lub kaw lus ua haujlwm tau zoo. Tus neeg saib xyuas raug ncaws tawm los ntawm
Firmware ib zaug ib ntus, kom CM tsis rov pib dua. Yog tias muaj qee yam tsis raug nrog CM
Firmware, tom qab ntawd tom qab ib lub sijhawm (lub sijhawm saib xyuas), CM yuav pib dua tshiab.
