Imikhiqizo Emisha Emisha 1 Stm-4 Sdh - 8E1+4GE PDH Fiber Multiplexer JHA-CPE8G4 – JHA

8E1+4GE PDH Fiber Multiplexer JHA-CPE8G4

Uhlolojikelele

Le divayisi iyidivayisi yokudlulisa i-point-to-point eyakhiwe ngesisekelo se-VLSI. Idivayisi inikeza isixhumi esibonakalayo se-1-8*E1, 1-4*10/100/1000M isixhumi esibonakalayo se-Ethernet (Wire Speed ​​1000M) nezixhumi ezibonakalayo ezi-2 zokunweba. 4* I-Ethernet interface iwukushintsha isikhombimsebenzisi, ingasekela i-VLAN. I-interface enwetshiwe engu-1 ingasetshenziswa njengesiteshi sokudlulisa se-RS232/RS485/RS422 idatha engavumelanisi, isignali yokuxhumana eyomile, ifoni yebhizinisi yedijithali ye-1Channel ingaba ozikhethela yona. Ivumelana nezimo kakhulu. Inomsebenzi we-alamu. Umsebenzi unokwethenjelwa, uzinzile, futhi ukusetshenziswa kwamandla aphansi, ukuhlanganiswa okuphezulu, usayizi omncane.

Isithombe Somkhiqizo

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• I-bandwidth ye-Fiber ifika ku-1.5G, i-Ethernet bandwidth i-Wire Speed ​​1000M
• Isilinganiso sokubonwa kwe-Ethernet ngu-10/100/1000M, uhhafu/ogcwele i-duplex Auto-Nego
• 4*Isixhumi esibonakalayo se-Ethernet siwukushintsha isikhombimsebenzisi, i-VLAN esekelayo, ingasethelwa ekuhlukanisweni okunengqondo kweziteshi ezi-4
• Nikeza isixhumi esibonakalayo sokuphatha ikhonsoli (RS232)
• Nikeza i-fiber interface 1+1 ukuvikela okubili(APS）umsebenzi
• Isixhumi esibonakalayo se-E1 sithobela i-G.703, sisebenzisa ukutholwa kwewashi ledijithali kanye nobuchwepheshe bokukhiya besigaba obushelelezi
• Isebenzisa ucingo olujwayelekile olu-2 (izibambo okungezona ezocingo) ezisethwe njengenombolo yocingo yocingo ye-oda lobunjiniyela(kuyakhetheka)
• Uma isignali yokubona yokulahlekelwa, ingathola ukuthi idivayisi eyirimothi ivaliwe noma i-fiber inqanyuliwe, futhi ibonisa i-alamu nge-LED.
• Idivayisi yasendaweni ingabuka isimo sokusebenza kwesilawuli kude
• Nikeza isixhumi esibonakalayo esinwetshiwe esingu-2, ungakwazi ukunweba idatha engu-1~2Channel esynchronous, njengekhodi RS232/RS485/RS422/Manchester;
• Nikeza umyalo wesixhumi esibonakalayo esikude i-Loop Back, isekela umsebenzi wendawo we-E1 Loop Back, isekela i-E1 LOS ne-alamu ye-AIS, lula ukulungiswa komugqa
• Ibanga lokuhamba lifika ku-2-100Km ngaphandle kokuphazamiseka
• Sekela umphathi we-SNMP (i-ejenti ye-SNMP ngaphakathi)
• I-AC 220V, DC-48V, DC24V ingakhethwa
• I-DC-48V/DC24V umsebenzi wokuthola i-polarity wokunikezwa kwamandla, I-Polarity-Free
