4E1 PDH Fiber Multiplexer(Desktop)
Iimbonakalo
*Ngokusekwe kwi-self-copyright IC
*Isixhobo sokubona imodyuli ebanzi eguqukayo
*Isebenzisa umnxeba oqhelekileyo we-2 wocingo (izibambo ezingezizo ezemfonomfono) ezisetwe njengocingo lwe-odolo-ngocingo lwefowuni (uyazikhethela)
*I-interface ye-E1 ithobela i-G.703, yamkele ukubuyiswa kwewotshi yedijithali kunye nobuchwephesha besigaba sokutshixa
*Xa isignali ye-optical ilahlekile, inokubona ukuba isixhobo esikude sivaliwe okanye ifayibha ivaliwe, kwaye ibonisa i-alamu nge-LED.
*Isixhobo sendawo sinokujonga imeko yokusebenza kwesixhobo esikude
*Nikeza umyalelo we-remote interface Loop Back, lula ukugcinwa komgca
*Umgama wothumelo ufikelela kwi-2-120Km ngaphandle kokuphazamiseka
*AC 220V, DC-48V, DC+24V inokuzikhethela
*DC-48V/DC+24V unikezelo lwamandla kunye nomsebenzi wokubona polarity oluzenzekelayo, xa lufakwe ngaphandle kokwahlula phakathi kokulungileyo nokubi.
Iiparamitha
