Amakosa atandatu asanzwe akorwa n'ibyuma bipima umucyo bya fiber optique

Fiber optique transceiver ni igikoresho cyo guhindura itumanaho rya Ethernet gihindura ibimenyetso by'amashanyarazi bihindagurika n'ibimenyetso by'amashanyarazi bihindagurika. Nanone cyitwa igikoresho gihindura amashanyarazi mu buryo bw'ifoto (Fiber Converter) ahantu henshi.

1. Itara rya Link ntiricana

(1) Reba niba umurongo wa fibre optique ufunguye;

(2) Kureba niba igihombo cy'umurongo wa fibre optique ari kinini cyane, kirenze urugero rw'ibikoresho byakira;

(3) Reba niba aho umurongo wa fibre optique uhujwe neza, aho umurongo wa TX uhujwe na RX yo kure, naho aho umurongo wa TX uhujwe na RX yo hafi. (d) Reba niba aho umurongo wa fibre optique winjijwe neza mu murongo wa igikoresho, niba ubwoko bwa jumper buhuye n'aho umurongo wa igikoresho uhurira, niba ubwoko bw'igikoresho buhuye n'aho umurongo wa fibre optique uhurira, kandi niba uburebure bw'aho umurongo wa igikoresho buhuye n'intera.

2. Itara rya "circuit Link" ntiricana

(1) Reba niba insinga y'umuyoboro ifunguye;

(2) Reba niba ubwoko bw'itumanaho buhuye: amakarita y'umuyoboro na za router n'ibindi bikoresho bikoresha insinga zinyuramo, naho swichi, hubs n'ibindi bikoresho bikoresha insinga zinyura mu buryo butaziguye;

(3) Reba niba igipimo cyo kohereza gihuye n'icyo gikoresho.

3. Gutakaza cyane paki y'urusobe rw'amakuru

(1) Umuyoboro w'amashanyarazi wa transceiver n'umurongo w'igikoresho cy'umuyoboro, cyangwa uburyo bwa duplex bw'umurongo w'igikoresho ku mpande zombi ntibihuye;

(2) Hari ikibazo ku nsinga yagonganye n'umutwe wa RJ-45, bityo reba;

(3) Ikibazo cyo guhuza fibre, niba jumper ijyanye n'igikoresho, niba pigtail ihuye na jumper n'ubwoko bwa coupler, nibindi;

(4) Niba igihombo cy'umurongo wa fibre optique kirenze ubushobozi bw'ibikoresho bwo kwakira.

4. Nyuma yuko transceiver ya fiber optique ihujwe, impera zombi ntizishobora kuvugana

(1) Ihuza ry'umugozi rirasubitswe, maze umugozi uhujwe na TX na RX urahindurwa;

(2) Interuro ya RJ45 n'igikoresho cyo hanze ntibihujwe neza (witondere uburyo bwo kunyuramo neza no gukurura). Interuro ya fibre optique (ceramic ferrule) ntabwo ihuye. Iri kosa rigaragarira cyane cyane muri transceiver ya 100M ifite imikorere yo kugenzurana hagati y'amashanyarazi, nka APC ferrule. Umurizo w'ingurube uhujwe na transceiver ya ferrule ya PC ntushobora kuvugana bisanzwe, ariko ntibizagira ingaruka kuri transceiver idakoresha optique.

5. Gufungura no kuzimya ikintu

(1). Birashoboka ko uburyo bwo kugabanya inzira y'urumuri ari bunini cyane. Muri iki gihe, icyuma gipima ingufu z'urumuri gishobora gukoreshwa mu gupima imbaraga z'urumuri z'inyuma y'urumuri. Iyo kiri hafi y'urwego rw'ubuhanga bwo kwakira, gishobora gufatwa nk'ikibazo cy'inzira y'urumuri kiri hagati ya 1-2dB;

(2). Birashoboka ko switch ihujwe na transceiver ifite ikibazo. Muri iki gihe, simbura switch na mudasobwa, ni ukuvuga ko transceivers ebyiri ziba zihujwe na mudasobwa, kandi impera zombi ni PING. Iyo itagaragara, ishobora gufatwa nk'iyinjira. Ikosa;

(3). Transceiver ishobora kuba ifite ikibazo. Muri iki gihe, ushobora guhuza impera zombi za transceiver kuri mudasobwa (ntunyuze muri switch). Nyuma y'uko impera zombi zidafite ikibazo na PING, ohereza dosiye nini (100M) cyangwa nyinshi kuva ku mpera imwe ujya ku yindi, kandi urebe umuvuduko wayo, niba umuvuduko wayo ugenda buhoro cyane (amadosiye ari munsi ya 200M ashobora koherezwa mu gihe kirenze iminota 15), ishobora gufatwa nk'ikosa rya transceiver.

6. Nyuma yuko imashini ipfuye ikongera kuyisubiza inyuma, isubira uko yari imeze

Iki kintu gikunze guterwa n’iyi switch. Iyi switch izakora isuzuma ry’amakosa ya CRC no kugenzura uburebure bw’amakuru yose yakiriwe. Iyo ikosa ribonetse, ipaki izajugunywa, hanyuma ipaki ikwiye yohererezwe.

Ariko, hari amapaki amwe afite amakosa muri ubu buryo ntashobora kuboneka mu gusuzuma no kugenzura uburebure bw'amakosa ya CRC. Ayo mapaki ntabwo azoherezwa cyangwa ngo ajugunywe mu gihe cyo kohereza amakuru. Azirundanya muri dynamic buffer. (Buffer), ntabwo ishobora koherezwa. Iyo ububiko bwuzuye, bizatuma switch igwa. Kuko muri iki gihe kongera gutangiza transceiver cyangwa kongera gutangiza switch bishobora gusubiza itumanaho ku buryo busanzwe.
