ECMM, DOCSIS 3.0, 2xGE, 2xMCX, SA120IE
Kufotokozera Kwachidule:
SA120IE ya MoreLink ndi DOCSIS 3.0 ECMM Module (Embedded Cable Modem Module) yomwe imathandizira njira zoyambira 8 ndi zinayi zolumikizirana kuti ipereke intaneti yamphamvu kwambiri.
SA120IE imalimbikitsidwa kutentha kuti iphatikizidwe mu zinthu zina zomwe zimafunika kuti zigwire ntchito panja kapena pamalo otentha kwambiri.

SA120IE ya MoreLink ndi DOCSIS 3.0 ECMM Module (Embedded Cable Modem Module) yomwe imathandizira njira zoyambira 8 ndi zinayi zolumikizirana kuti ipereke intaneti yamphamvu kwambiri.
SA120IE imalimbikitsidwa kutentha kuti iphatikizidwe mu zinthu zina zomwe zimafunika kuti zigwire ntchito panja kapena pamalo otentha kwambiri.
Pogwiritsa ntchito ntchito ya Full Band Capture (FBC), SA120IE si Cable Modem yokha, komanso ingagwiritsidwe ntchito ngati Spectrum Analyzer.
Mafotokozedwe a malonda awa akuphatikizapo mitundu ya DOCSIS® ndi EuroDOCSIS® 3.0 ya mndandanda wa zinthu za Embedded Cable Modem Module. Pogwiritsa ntchito chikalatachi, chidzatchedwa SA120IE. SA120IE ndi yolimba kutentha kuti iphatikizidwe muzinthu zina zomwe zimafunika kugwira ntchito panja kapena kutentha kwambiri. Kutengera ntchito ya Full Band Capture (FBC), SA120IE si Cable Modem yokha, komanso ingagwiritsidwe ntchito ngati Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink ndi yofunikira komanso yofunikira kugwiritsa ntchito. Mabowo atatu a PCB amaperekedwa mozungulira CPU, kotero kuti bracket yotenthetsera kapena chipangizo chofanana nacho chikhoza kumangiriridwa ku PCB, kuti kutentha komwe kwapangidwa kuchokera ku CPU kusunthire kupita ku nyumba ndi chilengedwe.
