I-Transponder yeFiber Node, SA120IE
Inkcazo emfutshane:
Olu lwazi lwemveliso luquka iinguqulelo ze-DOCSIS® kunye ne-EuroDOCSIS® 3.0 zoluhlu lweemveliso ze-Embedded Cable Modem Module. Ukudlula kolu xwebhu, luza kubizwa ngokuba yi-SA120IE. I-SA120IE iqiniswe ubushushu ukuze idityaniswe kwezinye iimveliso ezifunekayo ukuze zisebenze kwindawo engaphandle okanye kwindawo eshushu kakhulu. Ngokusekelwe kumsebenzi we-Full Band Capture (FBC), i-SA120IE ayisiyo i-Cable Modem kuphela, kodwa ingasetyenziswa njenge-Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). I-Heatsink iyimfuneko kwaye icwangciswe ngokwesicelo. Imingxunya emithathu ye-PCB ibonelelwa ejikeleze i-CPU, ukuze i-heatsinking bracket okanye isixhobo esifanayo sinamathele kwi-PCB, ukuhambisa ubushushu obuvelisiweyo kude ne-CPU ukuya kwindawo yokuhlala kunye nendawo engqongileyo.

Ibhloko yeNkqubo
Ijoni elijonga ngaphandle
Kusetyenziswa ijoni langaphandle ukuqinisekisa ukuba inkqubo isebenza ngokuthembekileyo.
I-Firmware ngamanye amaxesha, ukuze i-CM ingaphindi iqalise ukusebenza. Ukuba kukho into engalunganga nge-CM
I-Firmware, emva kwexesha elithile (ixesha lokulinda), i-CM iza kuqalisa ngokutsha ngokuzenzekelayo.

Iziqhagamsheli zeBhodi ukuya kwiBhodi phakathi kweDijithali kunye neBhodi yeCM
Kukho iibhodi ezimbini: ibhodi yedijithali kunye nebhodi ye-CM, ezisebenzisa iipere ezine zezihlanganisi zebhodi ukuya kwelinye ukuhambisa imiqondiso ye-RF, imiqondiso yedijithali kunye namandla.
Iiperi ezimbini zezihlanganisi ze-MCX ezisetyenziselwa i-DOCSIS Downstream kunye ne-Upstream RF Signals. Iiperi ezimbini ze-Pin Header/PCB Socket ezisetyenziselwa i-Digital Signals kunye ne-Power. Ibhodi ye-CM ibekwe phantsi kweBhodi yeDijithali. I-CPU ye-CM iqhagamshelwa kwi-housing nge-thermal pad ukuze idlulisele ubushushu kude ne-CPU ukuya kwi-housing kunye nokusingqongileyo.
Ukuphakama okudibeneyo phakathi kwamabhodi amabini yi-11.4+/-0.1mm.
Nantsi imizekelo yoqhagamshelo oluhambelanayo phakathi kwebhodi nebhodi:
