4E1+4GE PDH Fiber Multiplexer JHA-PD2PE2G4

Muchidimbu

Ichi chishandiso ndicho chinongedzo-ku-point optical transmission mudziyo wakagadzirwa pahwaro hweVLSI.Chigadzirwa chacho chinopa 1-4 * E1 interface, 1-4 * 10/100 / 1000M Ethernet interface (Wire Speed ​​1000M) uye 2 kuwedzera interfaces.4* Ethernet interface is switch interface, inogona kutsigira VLAN.1 yekuwedzera interface inogona kushandiswa senzira yekufambisa yeRS232/RS485/RS422 asynchronous data, yakaoma kuonana chiratidzo, 1Channel dhijitari bhizinesi foni inogona kusarudza.Inochinjika zvikuru.Iine alarm function.Basa racho rakavimbika, rakagadzikana, uye rakaderera kushandiswa kwesimba, kubatanidzwa kwepamusoro, hukuru huduku.

Features:

• Kubva pane self-copyright IC
• Iyo Fiber bandwidth inosvika 1.5G, Ethernet bandwidth iWire Speed ​​​​1000M
• Ethernet interface rate ndeye 10/100/1000M, hafu/yakazara duplex Auto-Nego
• 4 * Ethernet interface is switch interface, inotsigira VLAN, inogona kuseta kune 4 chiteshi zvine musoro kuparadzaniswa, tsigira QinQ;
• Ipa Console maneja interface (RS232)
• Ipa maviri fiber interface 1 + 1 chengetedza(APS）basa
• E1 interface inowirirana neG.703, inotora kudzoreredza wachi yedijitari uye tekinoroji yakatsetseka yechikamu
• Inoshandisa yakajairwa 2 waya nhare (isina-yenhare mubato) yakaiswa seinjiniya odha-waya hotline(kusarudza)
• Kana yekuona yakarasika chiratidzo, inogona kuona kuti mudziyo uri kure wakadzimwa kana kuti fiber yakabviswa, uye inoratidza alarm ne LED.
• Iyo yemuno mudziyo inogona kuona iri kure mudziyo unoshanda mamiriro
• Ipa 2 yekuwedzera interface, unogona kuwedzera 1 ~ 2Channel asynchronous data, yakadai seRS232/RS485/RS422/Manchester kodhi;
• Ipa kuraira iyo iri kure interface Loop Kumashure, tsigira yemuno E1 Loop Back basa, tsigira E1 LOS uye AIS alarm, kurerutsa mutsara kugadzirisa.
• Iyo yekufambisa kureba inosvika 2-100Km pasina kukanganisa
• Tsigira SNMP maneja (SNMP mumiriri mukati)
• AC 220V, DC-48V, DC24V inogona kusarudza
• DC-48V/DC24V magetsi ekupa polarity yekuona basa, Polarity-Yemahara
