Umgangatho oLungileyo wePdh-Sdh Multiplexer - 4E1+4FE(ukwahlulwa ngokwasemzimbeni) JHA-CPE4WF4 PDH Fiber Multiplexer – JHA

4E1+4FE(Ukwahlulwa ngokwasemzimbeni)JHA-CPE4WF4

I-PDH yeFayibha Multiplexer

Isishwankathelo

Olu luhlu lwezixhobo yinkampani ephuhlise ukuhanjiswa kwefayibha yePDH ezinikeleyo ngeVLSI ephuhliswe ngokwesiseko sesixhobo sokuhambisa i-optical. Ukubonelela nge-1-4 E1 ujongano, i-fiber optical interface ephambili kunye ne-backup, i-1-4 yokuhlukaniswa ngokomzimba 10/100M Fast Ethernet ujongano (i-independent-wire speed 100M ezimeleyo, i-bandwidth iyonke yi-4 * 100M), kunye ne-interface yokwandiswa kweshishini ezimbini. I-2 I-interface yenkonzo eyandisiweyo ingasetyenziswa njenge-RS232 / RS485 / RS422 idatha ye-asynchronous , isicelo siguquguquka kakhulu. Ukuzikhethela ifowuni yenkonzo yedijithali enye, isicelo sibhetyebhetye kakhulu. Ngomsebenzi we-alamu yesandi, yonke into ezinzileyo, ethembekileyo, ephantsi yokusetyenziswa kwamandla, ukudibanisa okuphezulu, ubungakanani obuncinci.

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• I-1-4 yokwahlukaniswa ngokomzimba 10/100M ujongano olukhawulezayo lwe-Ethernet, yonke isantya socingo se-FE Ethernet yi-100M, i-bandwidth iyonke yi-4 * 100M;
• Nika ujongano lolawulo lweConsole (RS232)
• Nika ujongano lwefiber ezimbini 1 + 1 khusela(APS）umsebenzi
• Ireyithi yojongano lwe-Ethernet yi-10/100M, isiqingatha/i-duplex epheleleyo ye-Auto-Nego
• Iphakheji ye-Ethernet yenkxaso yezakhelo ze-jumbo, ukuya kuthi ga kwi-10240 byte
• 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
• 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
