I-Professional China Modular Multi-Sevice Pdh - 4E1 PDH Fiber Multiplexer JHA-CPE4m – JHA

4E1 PDH Fiber Multiplexer JHA-CPE4m

Uhlolojikelele

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

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• I-Modular wide dynamic optical detector
• Isebenzisa ucingo olujwayelekile olu-2 (izibambo okungezona ezocingo) ezisethwe njengenombolo yocingo yocingo ye-oda lobunjiniyela(kuyakhetheka)
• Isixhumi esibonakalayo se-E1 sithobela i-G.703, sisebenzisa ukutholwa kwewashi ledijithali kanye nobuchwepheshe bokukhiya besigaba obushelelezi
• Uma isignali yokubona ilahlekile, ingathola ukuthi idivayisi ekude ivaliwe noma i-fiber inqanyuliwe, futhi ibonise i-alamu nge-LED.
• Idivayisi yasendaweni ingabuka isimo sokusebenza kwesilawuli kude
• Nikeza umyalo wesixhumi esibonakalayo esikude Loop Back, lula ukulungisa umugqa
• Ibanga likagesi lifika ku-2-120Km ngaphandle kokuphazamiseka
• I-AC 220V, DC-48V, DC+24V ingakhethwa
• I-DC-48V/DC+24V amandla kagesi anomsebenzi wokutholwa kwe-polarity okuzenzakalelayo, lapho efakwe ngaphandle kokuhlukanisa phakathi kokuhle nokubi.
