Amakosa atandatu asanzwe ya fibre optique

Fibre optique transceiver nigikoresho cya Ethernet cyohereza itangazamakuru rihinduranya intera ngufi-ihinduranya-ibyuma byamashanyarazi nibimenyetso birebire bya optique.Yitwa kandi guhinduranya amashanyarazi (Fibre Converter) ahantu henshi.

1. Itara rya Link ntirimurika

(1) Reba niba umurongo wa fibre optique ufunguye;

(2) Reba niba igihombo cya fibre optique ari kinini cyane, kirenze kwakira ibikoresho;

(3) Reba niba interineti ya fibre optique ihujwe neza, TX yaho ihujwe na RX ya kure, naho TX ya kure ihujwe na RX yaho..

2. Itara ryumuzunguruko Itara ntirimurika

(1) Reba niba insinga y'urusobe ifunguye;

.

(3) Reba niba igipimo cyo kohereza ibikoresho gihuye.

3. Gutakaza imiyoboro ikomeye

.

(2) Hariho ikibazo cyumugozi uhindagurika hamwe numutwe wa RJ-45, reba rero;

.

(4) Niba igihombo cya fibre optique irenze iyakirwa ryibikoresho.

4. Nyuma ya fibre optique transceiver ihujwe, impande zombi ntizishobora kuvugana

(1) Ihuza rya fibre irahindurwa, kandi fibre ihujwe na TX na RX irasimburwa;

(2) Imigaragarire ya RJ45 hamwe nibikoresho byo hanze ntabwo bihujwe neza (witondere kugororoka no gutambuka).Imigaragarire ya fibre optique (ceramic ferrule) ntabwo ihuye.Iri kosa rigaragarira cyane cyane muri 100M transceiver hamwe na foto ya elegitoroniki yo kugenzura, nka ferrule ya APC.Ingurube ihujwe na transceiver ya PC ferrule ntishobora kuvugana bisanzwe, ariko ntabwo bizagira ingaruka kubitandukanya bitari optique.

5. Fungura kandi uzimye ibintu

(1).Birashoboka ko inzira ya optique yerekana ari nini cyane.Muri iki gihe, metero ya optique irashobora gukoreshwa mugupima imbaraga za optique yo kwakira impera.Niba ari hafi yo kwakira ibyiyumvo byurwego rwo hejuru, birashobora gufatwa nkurunani rwinzira nziza muburyo bwa 1-2dB;

(2).Birashoboka ko switch ihujwe na transceiver ari amakosa.Muri iki gihe, usimbuze switch na PC, ni ukuvuga, transcevers ebyiri zahujwe na PC, kandi impande zombi ni PING.Niba itagaragara, irashobora gucirwa urubanza nkuwihindura.Ikosa;

(3).Transceiver irashobora kuba ifite amakosa.Muri iki gihe, urashobora guhuza impande zombi za transceiver kuri PC (ntunyure muri switch).Nyuma yimpera zombi ntakibazo na PING, ohereza dosiye nini (100M) cyangwa irenga kuva kuruhande rumwe kugeza kurundi, hanyuma urebe umuvuduko wacyo, niba umuvuduko utinda cyane (dosiye ziri munsi ya 200M zishobora kwimurwa muminota irenga 15), birashobora gusuzumwa muburyo bwo gutsindwa kwa transceiver

6. Imashini imaze guhanuka igatangira, isubira mubisanzwe

Iyi phenomenon muri rusange iterwa na switch.Guhindura bizakora CRC ikosa ryo kumenya no kugenzura uburebure kumakuru yose yakiriwe.Niba ikosa ryamenyekanye, paki izajugunywa, kandi paki iboneye izoherezwa.

Nyamara, udupaki tumwe na tumwe dufite amakosa muriki gikorwa ntushobora kuboneka mugushakisha amakosa ya CRC no kugenzura uburebure.Ibipaki nkibi ntibizoherezwa cyangwa gutabwa mugihe cyo kohereza.Bazegeranya muri buffer dinamike.(Buffer), ntishobora na rimwe koherezwa.Iyo buffer yuzuye, bizatera guhinduka guhanuka.Kuberako muriki gihe gutangira transceiver cyangwa gutangira switch birashobora kugarura itumanaho mubisanzwe.
