I-Transponder ye-Fiber Node, SA120IE
Incazelo emfushane:
Le ncazelo yomkhiqizo ihlanganisa izinguqulo ze-DOCSIS® kanye ne-EuroDOCSIS® 3.0 zochungechunge lwemikhiqizo ye-Embedded Cable Modem Module. Ngokusebenzisa lo mbhalo, izobizwa ngokuthi i-SA120IE. I-SA120IE iqiniswe izinga lokushisa ukuze ihlanganiswe kweminye imikhiqizo edingekayo ukuze isebenze endaweni engaphandle noma eshisayo kakhulu. Ngokusekelwe kumsebenzi we-Full Band Capture (FBC), i-SA120IE akuyona nje i-Cable Modem, kodwa futhi ingasetshenziswa njenge-Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). I-Heatsink iyimpoqo futhi iqondene nohlelo lokusebenza. Kunikezwa izimbobo ezintathu ze-PCB ezizungeze i-CPU, ukuze i-heatsinking bracket noma idivayisi efanayo inamathiselwe kwi-PCB, ukuze kudluliselwe ukushisa okukhiqizwe kude ne-CPU kuye endlini nasendaweni ezungezile.

Ibhulokhi Yesistimu
Inja Eqaphayo Yangaphandle
Kusetshenziswa i-watchdog yangaphandle ukuqinisekisa ukuthi uhlelo lusebenza ngendlela ethembekile. I-watchdog ikhahlelwa yi-
I-Firmware njalo ngezikhathi ezithile, ukuze i-CM ingaphinde isethwe kabusha. Uma kukhona okungahambi kahle nge-CM
I-Firmware, bese kuthi ngemva kwesikhathi esithile (isikhathi sokuqapha), i-CM izosetha kabusha ngokuzenzakalelayo.

Izixhumi zeBhodi neBhodi phakathi kweBhodi yeDijithali ne-CM
Kunamabhodi amabili: ibhodi yedijithali kanye nebhodi ye-CM, asebenzisa izixhumi ezine zebhodi nebhodi ukudlulisa amasignali e-RF, amasignali edijithali kanye namandla.
Amabhangqa amabili ezixhumi ze-MCX ezisetshenziselwa i-DOCSIS Downstream kanye ne-Upstream RF Signals. Amabhangqa amabili e-Pin Header/PCB Socket asetshenziselwa i-Digital Signals kanye ne-Power. Ibhodi le-CM libekwe ngaphansi kweBhodi leDijithali. I-CPU ye-CM ixhunywa endlini nge-thermal pad ukuze idlulisele ukushisa kude ne-CPU futhi iye endlini kanye nendawo ezungezile.
Ukuphakama okuhlanganisiwe phakathi kwamabhodi amabili kungu-11.4+/-0.1mm.
Nasi isibonelo soxhumano oluhambisanayo phakathi kwebhodi nebhodi:
Qaphela:
ImbangelaUmklamo webhodi kuya ebhodini webhodi le-PCBA ezimbilis,Ngakho-ke, ukuze kuqinisekiswe ukuxhumana okuzinzile nokuthembekile,nini
To ukuklama indlu, kufanele kucatshangelwe ubunjiniyela bokuhlanganisa kanye nezikulufo ukuze kulungiswe.
