The chete nzira nokusanzwira multimode kusafanana

Kana totaura nemashoko kutapurirana kubva kure nzvimbo kune imwe, kuwedzera pane tsika mhangura waya kuti mutengi Contractors vakokwa nokuisa ari Manyiminya waya. About ichi inonakidza Michina tine nhasi uye tozotaura.

Fiber-optic kukurukurirana mutsetse (FOL) ushande chinobva kupararira chiedza nemafungu kubudikidza migero chaiwo wakaitwa zvikuru kwakachena Goldstone girazi. Electrical nomunhu zvigadzirwa michina inopiwa kune chiratidzo convert, iyo zvinowanisa norukova chiedza pulses uye transmits navo waya. Panguva imwe mugumo chiedza mugamuchiri anogamuchira karwizi uye transcodes nayo kuna remagetsi pulses. Nekuti yose muitiro ari mukombiyuta aidzora uye digital kutendeuka, pasi kusarurama.

Kuvaka installer zvakadaro, shandisa chaiwo zvinhu - chimwe-rudzi nokusanzwira multimode.

Optic mitsetse zvaigara saka, kwete chete nokuda kwokushayiwa dzevamhan'ari kwemashoko chiratidzo. Pakati zvazvisingarambiki zvakanakira zvigadzirwa iri yakafara bhendi, simba chaizvo chiratidzo attenuation, risingaenzaniswi kuramba chero chipingaidzo ose remagetsi hunhu, guru hutachiwana siyana, zvichiita vemakumi zhinji makiromita. A chinokosha anobatsirwei kwenguva kukurukurirana basa, vakaisa vachishandisa installer, makore anenge 25.

mhando faibha

Kana kuwedzera Links uchishandisa faibha-optic mutsetse anosarudzwa kana multimode kana kuroorwa muoti faibha.

Chii waya ichi? Chinoumba ari faibha ndiyo Goldstone, ultrapure girazi, izvo nepano chiedza danda. A spraying haina kuitika nokuti indekisi goko refractive kudzika kudarika chinoumba, saka, chiedza danda riri zvachose zvinooneka kubva pamasvingo mukati faibha.

Multimode zvakanaka kuitira kuti kumhanya zvakawanda zana chiedza modes kuti nezvevanakomana zvakasiyana pamakona. Mumwe nzira ine nzira yayo uye, sezvo zvakaita kuti nemamwe kupararira nguva.

The chikuru drawback kwaiita faibha - muoti vakapararira, izvo nhete kuti bandwidth uye ichikutadzisa kufadza mutsetse pakureba. Kazhinji zvinotakura nokuti multimode kutaurirana mitsetse ndiwo chinhambwe kunonyanyisa vanenge 5 makiromita.

Dambudziko kuderedza muoti yokupararira anosarudza waya ane gradient refractive indekisi Profile of core. faibha ichi, mukusiyana kuti mureza options refractive indekisi zvinoderedza kubva pakati chinoumba kuti goko, izvo zvinopa zvinokosha kuvandudzika parameters ari chiratidzo zvitange.

The chete nzira faibha yakagadzirwa, inobva basa ichipfuura aakaudzwa mugero chete nzira imwe (inokosha). Izvi rakanakira zvakawanda. Vamwe unhu ari waya, akaitwa chete-rudzi michina, ane hurongwa unokosha kupfuura kuti zvakaberekwa multimode. Ndicho inokosha chinhu chinobata kusarudza vachifarira okutanga mainjiniya paakapa itsva internet optic Links. Zvechokwadi, chimwe-rudzi faibha kunopa attenuation pa 0,25db pa kiromita, kuti makakava pakati kwazvo duku uye yakafara bandwidth inopa zvakajeka uye kukurumidza kupararira yakawanda mashoko pasina kukanganiswa.

Asi pane chiri chizoro nhunzi iri mafuta. Iyi mhando ndiyo zvikuru anodhura pane multimode faibha. Sezvo kukura chiedza-anokufambisa cores mune rimwe-waya iri dikisa, nokuita kuti mwaranzi mazano ari waya akadaro akaoma uye kunoda kungwarira chaizvo kuzvidzora mune splicing. Mugumo connectors kuti mitsetse iyi uye vari zvakawanda anodhura pane multimode kontseviki mitsetse. Mukuwedzera, yokupedzisira nokuda nyore chiedza danda mazano Kukusvitsai chinoumba nyore chaizvo, cheap zvinotakura, iyo vaberekawo akawandisa kukwikwidzana makambani.
