China OEM Sm 1310nm 25km - 8E1+4FE PDH Multiplexer JHA-CPE8F4 – JHA

8E1+4FE PDF MultiplexerJHA-CPE8F4

Isishwankathelo

Esi sixhobo sibonelela nge-1-8 * E1 interface, i-1-4 * 10M / 100M i-Ethernet interface (i-Wire Speed ​​100M) kunye ne-2 interface yokwandisa. I-4 * i-Ethernet interface yi-switch interface, inokuxhasa i-VLAN. I-2 i-interface yokwandisa ingasetyenziselwa njengejelo lokuhambisa le-RS232 / RS485 / RS422 idatha ye-asynchronous. Ibhetyebhetye kakhulu. Inomsebenzi we-alam. Umsebenzi unokwethenjelwa, uzinzile, kunye nokusetyenziswa kwamandla aphantsi, ukudibanisa okuphezulu, ubungakanani obuncinci.

Ifoto yeMveliso

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• Isixhobo sokubona imodyuli ebanzi eguqukayo
• I-Ethernet (isantya somgca 100M) isantya sojongano yi-10M/100M, isiqingatha/i-duplex epheleleyo ye-Auto-Nego
• 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)
• Ukubonelela nge-2 ujongano lolwandiso lunokusetyenziswa njengejelo lothumelo lwe-RS232/RS485/RS422 idatha engavumelaniyo
• 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 Back, lula ukugcinwa kwelayini
• Umgama wothumelo ufikelela kwi-2-120Km ngaphandle kokuphazamiseka
• I-AC 220V, DC-48V, DC24V inokuzikhethela
• I-DC-48V/DC24V yobonelelo lwamandla umsebenzi wokubona ipolarity, iPolarity-Free
