Transponder-ka Fiber Node, SA120IE
Sharaxaad Gaaban:
Tilmaamaha badeecaddani wuxuu daboolayaa noocyada DOCSIS® iyo EuroDOCSIS® 3.0 ee taxanaha Modem-ka Modem-ka ee Fiilada La geliyay. Dukumeentigan, waxaa loogu yeeri doonaa SA120IE. SA120IE waa heerkul adag si loogu daro alaabada kale ee looga baahan yahay inay ka shaqeeyaan jawiga heerkulka dibadda ama heerkulka daran. Iyada oo ku saleysan shaqada Qabsashada Buuxa (FBC), SA120IE ma aha oo kaliya Modem-ka Fiilada, laakiin sidoo kale waxaa loo isticmaali karaa sida Falanqaynta Spectrum (SSA-Splendidtel Spectrum Analyzer). Heatsink waa qasab waana mid gaar u ah codsiga. Saddex godad oo PCB ah ayaa lagu bixiyaa agagaarka CPU-ga, si qalab kuleylin ah ama qalab la mid ah loogu dhejiyo PCB-ga, si kulaylka la soo saaray looga wareejiyo CPU-ga loona wareejiyo guryaha iyo deegaanka.

Baloogga Nidaamka
Ilaaliyaha Dibadda
Ilaaliye dibadeed ayaa loo isticmaalaa si loo hubiyo in si kalsooni leh loo shaqeeyo nidaamka. Ilaaliye waxaa la dagaallamaa
Firmware-ka mar mar, si CM-gu uusan dib u bilaabin. Haddii ay wax ka khaldan yihiin CM-ga
Firmware-ka, ka dib muddo cayiman (waqtiga ilaalada), CM-gu si otomaatig ah ayuu dib u bilaabi doonaa.

Xidhiidhiyayaasha looxa-ilaa-Guddida ee u dhexeeya Guddiga Dijital ah iyo Guddiga CM
Waxaa jira laba loox: loox dijitaal ah iyo loox CM ah, kuwaas oo adeegsada afar lammaane oo isku xira loox-ilaa-loox si ay u gudbiyaan calaamadaha RF, calaamadaha dijitaalka ah iyo awoodda.
Laba lammaane oo isku xira MCX ah ayaa loo isticmaalaa Calaamadaha RF ee DOCSIS ee Hoos u socda iyo kuwa Sare. Laba lammaane oo ah Madaxa Biinanka/Badhanka PCB ee loo isticmaalo Calaamadaha Dijital ah iyo Korontada. Looxa CM waxaa la dhigayaa Guddiga Dijital ah. CPU-ga CM waxaa lala xiriiriyaa guriga iyada oo loo marayo suufka kulaylka si kulaylka looga wareejiyo CPU-ga loona wareejiyo hoyga iyo deegaanka.
Dhererka isku dhafan ee u dhexeeya laba loox waa 11.4+/-0.1mm.
Waa kan sawirka isku xidhka looxa-ilaa-saxanka:
