8 IP MUX-Scrambling and QAM
DX328 IP Mux-Scrambling and modulation module is the latest generational Mux-scrambling-modulating all-in-one device developed by DEXIN. Each DX328 daughter card combines 8 multiplexing modules, 8 scrambling modules and 8 QAM (DVB-C) modulating modules, which makes it posssible that every daughter card works stand-alone. It supports maximum 256 IP MPTS/SPTS (per daughter card) input through the GE port and 8 adjacent carriers（30M~860M）output through the two RF output interfaces.
This DX328 IP Mux-Scrambling and modulation module has adopted slot structure to allow maximum 3 DX328 cards to insert one device simultaneously. To draw a conclusion, its excellent integrated level, powerful performance and low cost make it adequate for the new generation CATV system.

EOC
Ethernet over coax
Toto koaxové řešení je vhodné pro menší počet zákazníků ( násobky 64 ) - je levnější než naše miniCMTS Docsis 3.0 která je vhodná pro instalace do 500 modemů. Mezi vlastnosti hlavně patří propracovaý QoS ( lze nastavit třídy až na portech modemu ), vysoká odolnost vůči rušení a hlavně možný útlum až 60 dB. Zařízení dodáváme ve venkovním i vnitřním provedení.
Námi nabízené řešení je postavené na Atherosu čipu, který přes jeden headend modem dodává reálnou rychlost 300 Mb/s . Koncové modemy jsou dodávány pouze ve verzi 100 Mb/s s reálnou rychlostí 88 Mb/s.
Na fotkách vidíte zařízení s PON modulem, ale umíme vyrobit zařízení i bez něj. S více headend modemy max. 4 kusy ( pak by se jednalo o reálnou propustnost 1200 Mb/s ), nadále je možné ho osadit na přání dálkovým napájením ať přes UTP nebo po KOAXu.
Tyto a ostatní zařízení dodáváme jako komplexní stavebnici opticko – koaxiální včetně rozsáhlého managementu. Zařízení vám po domluvě můžeme odborně namontovat a proškolit vaše techniky.
