4E1+4GE PDFIfayibhaMultiplexer

Isishwankathelo

Esi sixhobo sisixhobo sokuhambisa i-point-to-point optical ephuhliswe kwisiseko se-VLSI. Isixhobo sibonelela nge-1-4 * E1 interface, i-1-4 * 10/100/1000M i-Ethernet interface (i-Wire Speed ​​1000M) kunye ne-2 i-interfaces yokwandisa. I-4 * i-Ethernet interface yi-switch interface, inokuxhasa i-VLAN. I-interface ye-1 yokwandisa ingasetyenziselwa njengejelo lokuhanjiswa kwe-RS232 / RS485 / RS422 idatha ye-asynchronous, isignali yokudibanisa eyomileyo, i-1Channel ifowuni yeshishini yedijithali inokuzikhethela. Ibhetyebhetye kakhulu. Inomsebenzi we-alam. Umsebenzi unokwethenjelwa, uzinzile, kunye nokusetyenziswa kwamandla aphantsi, ukudibanisa okuphezulu, ubungakanani obuncinci.

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• I-Fiber bandwidth ifikelela kwi-1.5G, i-Ethernet bandwidth yi-Wire Speed ​​1000M
• Ireyithi yojongano lwe-Ethernet yi-10/100/1000M, isiqingatha/i-duplex epheleleyo ye-Auto-Nego
• I-4 * i-Ethernet interface yi-switch interface, i-VLAN yenkxaso, inokuseta kwi-4 ye-channel logical isolation
• Nika ujongano lolawulo lweConsole (RS232)
• Nikeza ujongano lwefiber ezimbini 1+1 ukukhusela (APS) umsebenzi
• Ujongano lwe-E1 luthobela i-G.703, lwamkele ukubuyiswa kwewotshi yedijithali kunye nobuchwepheshe besigaba sokutshixa
• Isebenzisa umnxeba oqhelekileyo we-2 wocingo (izibambo ezingezizo ezemfonomfono) ezisetwe njengefowuni yeodolo yobunjineli(uyazikhethela)
• Xa i-optical ilahleka isignali, inokubona isixhobo esikude sicinyiwe okanye ifayibha ivaliwe, kwaye ibonisa i-alam nge-LED.
• Isixhobo sendawo sinokujonga imeko yokusebenza kwesixhobo esikude
• Ukubonelela nge-2 interface yokwandisa, unokwandisa i-1 ~ 2Channel idatha ye-asynchronous, njenge-RS232 / RS485 / RS422 / ikhowudi yaseManchester;
• Nika umyalelo ujongano olude Loop ngasemva, inkxaso yendawo E1 Loop Back umsebenzi, inkxaso E1 LOS kunye AIS alarm, lula ukugcinwa umgca
• Umgama wothumelo ufikelela kwi-2-100Km ngaphandle kokuphazamiseka
• Inkxaso yomphathi we-SNMP (iarhente ye-SNMP ngaphakathi)
• I-AC 220V, DC-48V, DC24V inokuzikhethela
• I-DC-48V/DC24V yobonelelo lwamandla umsebenzi wokubona ipolarity, iPolarity-Free
