Mu gihe hari iterambere ryihuse mu bikorwa remezo by’itumanaho, inganda z’itumanaho zigenda zihura n’imbogamizi ikomeye mu iterambere. Imwe mu ikoranabuhanga ry’ingenzi mu itumanaho ry’amajwi - Wavelength Division Multiplexing (WDM) - yabaye igisubizo cy’ingenzi cyo gutsinda izi mbogamizi zifatika.

Iyo fibre optique igereranywa n'umuhanda munini, itumanaho gakondo ry'uburebure bw'umuraba umwe riba nk'ikinyabiziga kimwe gitwara umuhanda wose. Ikoranabuhanga rya WDM rigabanya iyi nzira ifatika mu "mihanda myinshi idahungabanya" (uburebure butandukanye bw'umuraba), bigatuma ibimenyetso byinshi by'amakuru byoherezwa icyarimwe binyuze muri fibre imwe. Ibikoresho by'ingenzi bifasha iyi koranabuhanga ni akayunguruzo ka DWDM (Dense Wavelength Division Multiplexing). Iyi nkuru itanga isesengura rigufi ry'iri koranabuhanga.

I. Amahame y'ingenzi n'ibyiza bya Filteri zitagira aho zibogamiye

DWDM idakora, OSP Ring OADM, Umuyoboro 1, Intera ya 100 GHz, Umuyoboro 48, Fiber ya 900um 1m, SC/APC Connector

Ijambo "passive" risobanura ko igikoresho kidakenera ingufu ziturutse hanze. Ahubwo, cyishingikiriza gusa ku bikoresho bya elegitoroniki cyangwa ibyuma bigabanya kugira ngo gitandukanye neza (demultiplex) cyangwa gihuze ibimenyetso bya optique (multiplex) by'uburebure butandukanye bw'urumuri.

Iyi miterere y'izuba gusa itanga ituze n'ubwirinzi budasanzwe, bigatuma igikoresho kidahura n'ibibazo by'amashanyarazi. Kubera iyo mpamvu, kibereye cyane gukoreshwa igihe kirekire mu byumba bikomeye by'ibikoresho by'itumanaho cyangwa ahantu habi ho hanze.

Mu miterere y’urusobe rw’amajwi, ibyuma biyungurura amajwi bya DWDM bitagira aho bihuriye n’amajwi bikora nk’ “ibigenzura ubwikorezi bw’imodoka.” Bikurikiza cyane amahame y’Ihuriro Mpuzamahanga ry’Itumanaho (ITU-T), bigabanyijemo inzira nyinshi cyangwa amagana z’itumanaho ryigenga rifite intera nto cyane y’uburebure bw’umuraba.

Ibi bivuze ko fibre imwe y’urumuri, mbere yari ifite ubushobozi bwo gutwara ikimenyetso kimwe gusa, ishobora kongera ubushobozi bwayo bwo kohereza inshuro nyinshi, bigatuma imikorere ya spectral irushaho kuba myiza cyane.

II. Imiterere n'agaciro bisanzwe by'ishyirwa mu bikorwa

DWDM idakora, OSP Ring OADM, Umuyoboro 1, Intera ya 100 GHz, Ch52, Monitor (1%), Fiber ya 900um 1m, Idafite Connector

Izi filters zikoreshwa mu buryo busanzwe zikozwe mu buryo busanzwe bwo gupakira, nka modules za LGX cassette cyangwa amakarita ya santimetero 19, kandi zifite fibre optic connectors nziza cyane kugira ngo zihuzwe neza n'imiyoboro ya fibre imwe isanzweho. Indangagaciro z'ingenzi zikoreshwa muri zo zirimo:

Kwagura Metropolitan Transmission na Backbone Network

Hatabayeho kongeramo insinga nshya za fibre, ikoranabuhanga rya WDM rishobora kongera byihuse uburyo bwo kohereza amakuru mu miyoboro y’umujyi n’imiyoboro y’ibanze y’akarere, rigakemura ibibazo byinshi byo gutanga amakuru nk’amashusho yo mu rwego rwo hejuru no gukoresha ikoranabuhanga rya “cloud computing”.

Uruganda rwo hanze (OSP) n'imiyoboro yo kugera ku bandi

Kubera imiterere yabyo idakora cyane kandi idakora ku buryo bwo kubungabunga, ibi bikoresho bikoreshwa cyane mu miyoboro yo gukwirakwiza amatara hanze, bigabanyiriza neza ikiguzi cy'igihe kirekire cyo gukora no kubungabunga abakora itumanaho.

Guhuza Ikigo cy'Amakuru

Mu bigo by’amakuru cyangwa hagati y’ibigo byinshi by’amakuru, ibyuma bifunguye bidakoresha imbaraga bifasha mu gutuma ibimenyetso byinshi by’urumuri bigenzurwa neza kandi bigatakaza cyane uburyo bwo kubishyiramo, bigatuma amakuru yoherezwa vuba kandi mu buryo buhamye.
