I-Digital Video Audio Fiber Optical Multiplexer edayiswa ngokushisayo - 8E1+LCD Isibonisi +SNMP JHA-C2P-E8bF4R2 PDH Fiber Multiplexer – JHA

8E1+LCD Isibonisi +SNMP JHA-C2P-E8bF4R2

I-PDH Fiber Multiplexer

Uhlolojikelele

Le divayisi inokulawula ikhonsoli, inikeza isivikelo se-fiber backup esingu-1+1, iphoyinti lokukhomba ukudluliswa kwe-optical, isibonisi se-LCD, esisekelweni sokuthuthukiswa kwenkampani yethu ye-PDH optical transmission, sebenzisa i-VLSI ekhethekile kanye ne-SNMP NMS.

Idivayisi inikeza isikhombimsebenzisi se-1-8 * E1, i-interface ye-1-4 * 10/100M Ethernet (Isivinini se-Wire 100M) kanye ne-interface yokunweba engu-2. I-4Channel Ethernet interface iwukushintsha isikhombimsebenzisi, ingasekela i-VLAN. 2 isikhombikubona esinwebekayo singasetshenziswa njengesiteshi sokudlulisa se-RS232/RS485/RS422 idatha ye-asynchronous. Ivumelana nezimo kakhulu. Inomsebenzi we-alamu. Umsebenzi unokwethenjelwa, uzinzile, futhi ukusetshenziswa kwamandla aphansi, ukuhlanganiswa okuphezulu, usayizi omncane

Isithombe Somkhiqizo

Izici

• Ihlinzeka nge-8 E1 transparent transparent;
• Inombukiso we-char 16*2 LCD ne-ejenti ye-SNMP ngaphakathi
• Nikeza isixhumi esibonakalayo sokuphatha ikhonsoli (RS232)
• Nikeza nge-fiber interface 1+1 ukuvikela (APS) umsebenzi, kanye ne-ALS (Ukuvala shaqa/ukunciphisa i-Laser okuzenzakalelayo)
• Ukusekela usayizi wephakheji ye-Ethernet engu-1916 byte kanye nembobo ye-Ethernet engu-4 kungasethwa ngokuhlukene, futhi umkhawulokudonsa we-ethernet ungasetha isisekelo sokuphindaphinda okungu-32K
• Isebenzisa ucingo olujwayelekile olu-2 (izibambo okungezona ezocingo) ezisethwe njengenombolo yocingo yocingo ye-oda lobunjiniyela(kuyakhetheka)
• Nikeza nge-fiber interfaces ezimbili, eyodwa njengenkosi, enye njengesigqila, iqinisekisa ukudluliswa kwesevisi okungaphazamiseki
• Izinga le-optical port liyi-155Mbps, uhla lokudlulisela lungafinyelela ku-25KM, 40KM, 60KM, 80KM noma 120KM;
• Ikhodi yesixhumi esibonakalayo ye-E1 yi-HDB3, isici sokudlidliza se-E1 sivumelana ne-ITU-T G.703, G.823 ne-G.742;
• Imbobo ye-Ethernet isekela i-duplex egcwele/isigamu, i-10/100M auto-Nego;
• Imbobo ye-Ethernet isekela umsebenzi we-VLAN futhi inemodi yokuhlukanisa engu-4 yokukhetha umsebenzisi;
• Inomsebenzi we-alamu ophelele futhi ingaqapha isimo sedivayisi ekude;
• Isekela i-Fiber Loop-back emibili, kanye nemodi ye-loop-back ye-Four E1, futhi iphathe idivayisi kalula;
• i-alamu enkulu elungisekayo yomsebenzisi kanye ne-alamu encane, isibonisi nge-LCD ne-alamu yomsindo kusipika;
• I-AC 220V, DC-48V, DC+24V ingakhethwa
• I-DC-48V/DC+24V umsebenzi wokuthola i-polarity wokunikezwa kwamandla, I-Polarity-Free
