I-4E1 PDH Fiber Multiplexer(Ideskithophu)

I-4E1 PDH Fiber Multiplexer(Ideskithophu) Isithombe Esifakiwe
  • I-4E1 PDH Fiber Multiplexer(Ideskithophu)

Incazelo emfushane:

Le divayisi inikeza isixhumi esibonakalayo esingu-1-4* E1 , ucingo olujwayelekile 2 njengocingo lwe-oda lobunjiniyela (ongakukhetha).Ivumelana nezimo kakhulu.Inomsebenzi we-alamu.Umsebenzi unokwethenjelwa, uzinzile, futhi ukusetshenziswa kwamandla aphansi, ukuhlanganiswa okuphezulu, usayizi omncane.

Izici
*Ngokusekelwe ku-copyright yakho IC
*I-Modular wide dynamic optical detector
*Isebenzisa izintambo ezijwayelekile ezingu-2 (izibambo ezingezona ezocingo) ezisethwe njengocingo locingo lwe-oda lobunjiniyela(kuyakhetheka)
*Isixhumi esibonakalayo se-E1 sithobela i-G.703, sisebenzisa ukutholwa kwewashi ledijithali kanye nobuchwepheshe bokukhiya besigaba obushelelezi
*Lapho isignali yokubona ilahlekile, ingathola ukuthi idivayisi ekude ivaliwe noma i-fiber inqanyuliwe, futhi ibonisa i-alamu nge-LED
*Idivayisi yendawo ingabuka isimo sokusebenza kwedivayisi ekude
*Nikeza umyalo wesixhumi esibonakalayo esikude Loop Back, lula ukulungisa umugqa
*Ibanga likagesi lifinyelela ku-2-120Km ngaphandle kokuphazamiseka
*AC 220V, DC-48V, DC+24V kungaba ozikhethela yona
*I-DC-48V/DC+24V amandla kagesi anomsebenzi wokubona ukuvuleka okuzenzakalelayo, lapho efakwe ngaphandle kokuhlukanisa phakathi kokuhle nokubi
