Nyanzvi yeChina Modular Multi-Sevice Pdh - 4E1 PDH Fiber Multiplexer JHA-CPE4m - JHA

4E1 PDH Fiber Multiplexer JHA-CPE4m

Overview

Ichi chishandiso chinopa 1-4* E1 interface , Standard 2 waya runhare seinjiniya odha-waya (optional). Inochinjika zvikuru. Iine alarm function. Basa racho rakavimbika, rakagadzikana, uye rakaderera kushandiswa kwesimba, kubatanidzwa kwepamusoro, hukuru huduku.

Features

• Kubva pane self-copyright IC
• Modular wide dynamic optical detector
• Inoshandisa yakajairwa 2 waya nhare (isina-yenhare mubato) yakaiswa seinjiniya odha-waya hotline(kusarudza)
• E1 interface inowirirana neG.703, inotora kudzoreredza wachi yedijitari uye tekinoroji yakatsetseka yechikamu
• Kana chiratidzo chemaziso charasika, chinogona kuona kuti mudziyo uri kure wakadzimwa kana kuti faibha yakadzimwa, uye inoratidza alarm ne LED.
• Iyo yemuno mudziyo inogona kuona iri kure mudziyo unoshanda mamiriro
• Ipa kuraira iyo iri kure interface Loop Back, kurerutsa mutsara kugadzirisa
• Iyo yekufambisa kureba inosvika 2-120Km pasina kukanganisa
• AC 220V, DC-48V, DC+24V inogona kusarudza
• DC-48V/DC+24V magetsi ine otomatiki polarity yekuona basa, kana yaiswa pasina mutsauko pakati pezvakanaka nezvakaipa.
