Multiplexers SDH: tsananguro, izita

Digital multiplexers ikashandiswa musoro namano kuti zvakagadzirirwa kuti aidzora kupararira mashoko multiple mashoko manyuko mugomba chete goho chiteshi. Kutaura zvazviri, mumwe mudziyo wakadaro vakawanda-digital positional haizoshandisi. Saka, zvinogona akagumisa kuti digital multiplexer ndiye chinja chiyamuro anonongedzera kune rimwe goho mutsetse. Nyaya iyi ichakurukurwa imwevo mhando mano - Manyiminya multiplexers SDH.

Kwakadaro mano akagadzirirwa kushanda pamwe date nokuyerera achishandisa chiedza matanda, izvo zvakasiyana kuyaruka kana amplitude nesefa uye wavelength. SDH multiplexers nekufambisa mashoko pamusoro E1 hova uye Ethernet mitsetse kuendesa faibha-optic network. Vanoshanda imwe kana mbiri Manyiminya fibers (kuroorwa-rudzi kana multimode) pa 155, 520 Mbit / s ari wavelength pamusoro 1550/1310 nm. SDH multiplexers kuona kusvika 126 pfungwa kunyorerana.

Zvakanakira vakadaro mano zvinosanganisira kushinga, zvekushandisa kuchengeteka, kudzivirira kugura mashoko zvitange.

SDH-multiplexers vari nyore scalable waisanganisira huru chikwata kusvika nhatu mamwe Ethernet yedzimudzangara migero modules E1, paintercom, uye nzira PM.

mano aya anozivikanwa ne kumusoro "kusimba" Network. Implementation E1 ane yakaderera jitter ukoshi chaichengetwa mureza uyu E1 panguva yaunonyanya kushandisa vasakukurwa, uye kukundikana STM-1 hurongwa nguva. Inowanikwa parameters kubvumira kuongorora chikanganiso mu kudyidzana chiteshi , uye kuita nokuchinja kuti humwewo gwara. Optical nzira uye simba yakachengeterwa 1 + 1. Kureva, kana kushanda iri internet optic mugero, kana kukuvara pamusoro waya, kubatana pakati subscribers inochengeterwa.

SDH multiplexers nyore kubatanidzwa nemamwe marudzi SDH michina. Vanogona kushanda mune synchronous uye asynchronous modes vanobvumirwa mu multimode uye chete-rudzi faibha. SDH multiplexer anotsigira kure configuration uye kurapa TCP / IP, 10/100 BaseT Protocol.

nokuchinja mano vakadaro kazhinji rakakamurwa mhando mbiri: chinouraya uye I / O. The musiyano kwemarudzi izvi haisi chikamu zvengarava, uye placement ari mudziyo iri SDH Network. Inouraya multiplexer rinopedzisa uwandu hwezvinhu zvose zvabatanidzwa. migero pakufamba kuenda kwaaishanda pakati pavo vazhinji goho hova uye chiyamuro. The mhando zviridzwa dzaifanoiswa rechipiri transmits uwandu hwezvinhu zvose zvabatanidzwa. mutsetse uri mutsetse achitora chinhu zvenguva chinzvimbo. Saka mashoko rechibharo Mipata zvinobva uwandu hwezvinhu zvose zvabatanidzwa. murukova kana jekiseni mauri.

Vagadziri Most kubudisa yezvisikwa multiplexers SDH mhando, dzinoshandiswa chiyamuro / goho chinouraya, uyewo muchinjikwa connectors - zvichienderana akagadzawo modules vari uwandu hwezvinhu zvose zvabatanidzwa. dzavo uye vabati vechibharo zvengarava.

In mhedziso, tinoisa kuti internet optic multiplexers, vari kuwana kuwedzera kukurumbira nokuda ndichibvunza kukura iyi mhando yokukurukurirana. nokuti internet optic michina yemberi.
