Inyandiko ku gishushanyo mbonera cya Fiber Transceiver!

Kwaguka vuba kw'imiyoboro ya fiber optique, harimo na serivisi z'amakuru zipimirwa mu bwinshi bw'amakuru cyangwa bandwidth, bigaragaza ko ikoranabuhanga ryo kohereza fibre optique riri kandi rizakomeza kuba igice cy'ingenzi cya sisitemu z'imiyoboro y'ejo hazaza. Abashushanya imiyoboro y'amakuru barushaho kwishimira ibisubizo bya fibre optique, kuko gukoresha ibisubizo bya fibre optique bituma imiterere y'imiyoboro y'amakuru yoroshye n'izindi nyungu nka EMI (electromagnetic interference) no kurinda amakuru. Imashini zitwara fibre optique zigira uruhare runini muri izi mibonano ya fibre optique. Mu gushushanya imashini itwara fibre optique, hari ibintu bitatu bigomba kuzirikanwaho: imiterere y'ibidukikije, imiterere y'amashanyarazi, n'imikorere y'amakuru.
Imashini itwara amakuru ya fiber optique ni iki?

Transceiver ya fiber optique ni igice cyigenga cyohereza no kwakira ibimenyetso. Ubusanzwe, ikoresha igikoresho gitanga umwanya umwe cyangwa myinshi ya transceiver, nka router cyangwa network interface card. Transceiver ifata amashanyarazi yinjira ikayahindura urumuri ruturutse kuri diode ya laser cyangwa LED. Urumuri ruturutse kuri transceiver ruhuzwa na fiber binyuze kuri connector hanyuma rukoherezwa binyuze kuri fibre optique cable. Urumuri ruturutse ku mpera ya fiber ruhuzwa na receiver, aho detector ihindura urumuri mo ikimenyetso cy'amashanyarazi, hanyuma igikoresho cyakira kikayikoresha neza.​
Ibitekerezo ku gishushanyo
Amasano ya Fiber optique ashobora kwihanganira umubare munini w'amakuru mu ntera ndende ugereranije n'ibisubizo by'insinga z'umuringa, ibyo bikaba byaratumye ikoreshwa rya transceivers za fiber optique rirushaho kuba ryiza. Mu gihe cyo gushushanya transceivers za fiber optique, ingingo zikurikira zigomba kwitabwaho.
Imiterere y'ibidukikije
Imbogamizi imwe ituruka ku kirere cyo hanze—cyane cyane ikirere kibi cyane ahantu hanini cyangwa hagaragara. Ibi bice bigomba gukora mu bihe bikomeye by’ibidukikije no mu bushyuhe bwinshi. Ikibazo cya kabiri cy’ibidukikije kijyanye n’igishushanyo mbonera cya transceiver ya fiber optique ni ibidukikije bya motherboard birimo ikoreshwa ry’ingufu za sisitemu n’imiterere y’ubushyuhe.
Akamaro gakomeye ka transceivers za fiber optique ni uko ingufu zabo z'amashanyarazi ari nkeya cyane. Ariko, iyi mashini ikoresha ingufu nke ntibivuze ko imiterere y'ubushyuhe ishobora kwirengagizwa mu gihe cyo guteranya imiterere y'ibikoresho bya host. Hagomba gushyirwamo umwuka uhagije cyangwa uburyo bwo guhumeka kugira ngo bifashe mu gusohora ingufu z'ubushyuhe zisohoka muri module. Igice cy'ibi bisabwa cyuzuzwa na cage ya SFP isanzwe iri kuri motherboard, nayo ikora nk'umuyoboro w'ingufu z'ubushyuhe. Ubushyuhe bw'aho bugaragara butangwa na Digital Monitor Interface (DMI) iyo mainframe ikora ku bushyuhe bwayo ntarengwa ni cyo kizamini cya nyuma cy'imikorere y'imiterere y'ubushyuhe muri rusange.
Imiterere y'amashanyarazi
Mu by’ukuri, transceiver ya fiber optique ni igikoresho cy’amashanyarazi. Kugira ngo amakuru anyura muri module akomeze gukora neza nta makosa, ingufu zijya kuri module zigomba kuba zihamye kandi zitagira urusaku. Icy’ingenzi kurushaho, ingufu ziyobora transceiver zigomba kuyungururwa neza. Imashini zisanzwe ziyungurura zivugwa mu masezerano y’inkomoko nyinshi (MSA), yayoboye imiterere y’umwimerere y’izi transceiver. Imwe muri iyo miterere mu bisobanuro bya SFF-8431 igaragara hano hepfo.
Imiterere y'urumuri
Umusaruro w'urumuri upimirwa mu gipimo cy'amakosa ya biti cyangwa BER. Ikibazo cyo gushushanya transceiver y'urumuri ni uko ibipimo by'urumuri by'urumuri n'urumuri bigomba kugenzurwa kugira ngo uburyo bwose bwo kugabanya ikimenyetso cy'urumuri mu gihe kigenda muri fibre bitavamo imikorere mibi ya BER. Igipimo cy'ingenzi ni BER y'urumuri rwose. Ni ukuvuga ko aho urumuri rutangiriye ari ho haturuka ikimenyetso cy'amashanyarazi gitwara transceiver, kandi ku iherezo, ikimenyetso cy'amashanyarazi cyakirwa n'urumuri kandi kigasobanurwa n'urusobe rw'amashanyarazi ruri muri host. Kuri izo sano z'itumanaho zikoresha transceiver y'urumuri, intego nyamukuru ni ukwerekana imikorere ya BER mu ntera zitandukanye z'urumuri no kwemeza ko habaho imikoranire yagutse n'urumuri rw'abandi ruturutse ku bacuruzi batandukanye.
