8E1+4FE(Ukuzihlukanisa ngokomzimba)JHA-CPE8WF4

I-PDH Fiber Multiplexer

Uhlolojikelele

Lolu chungechunge lwemishini yinkampani eyakha i-PDH fiber transmission enikezelwe i-VLSI eyakhiwe ngesisekelo sephuzu lokukhomba imishini yokudlulisela optical. Nikeza 1-8 E1 kokuxhumana, isixhumi esibonakalayo esiyisisekelo nesisekelayo se-fiber optical, isixhumi esibonakalayo sokuhlukaniswa ngokomzimba esingu-10/100M Fast Ethernet esibonakalayo (isivinini esizimele sezintambo ezine esingu-100M, isamba somkhawulokudonsa si-4*100M), kanye nesixhumi esibonakalayo sokunwetshwa kwebhizinisi okubili. 2 I-interface yesevisi enwetshiwe ingasetshenziswa njengedatha ye-asynchronous RS232 / RS485 / RS422, uhlelo lokusebenza luvumelana nezimo kakhulu. Ongakukhetha ngocingo olulodwa lwenkonzo yedijithali, uhlelo lokusebenza luvumelana nezimo kakhulu. Ngomsebenzi we-alamu yomsindo, konke okuzinzile, okuthembekile, ukusetshenziswa kwamandla okuphansi, ukuhlanganiswa okuphezulu, usayizi omncane.

Isithombe Somkhiqizo

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• 1-4 ukuzihlukanisa ngokomzimba 10/100M isixhumi esibonakalayo se-Ethaneti esheshayo, yonke isivinini socingo esizimele se-FE Ethernet singu-100M, isamba somkhawulokudonsa ngu-4*100M;
• Nikeza isixhumi esibonakalayo sokuphatha ikhonsoli (RS232)
• Nikeza i-fiber interface 1+1 ukuvikela okubili(APS)umsebenzi
• Isilinganiso sokubonwa kwe-Ethernet ngu-10/100M, uhhafu/ogcwele i-duplex ye-Auto-Nego
• Iphakheji ye-Ethernet isekela amafreyimu we-jumbo, afika ku-10240 byte
• 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) ezimiswe njengocingo locingo lwe-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 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 likagesi 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
