Ibice bikurikira bitanga isesengura rirambuye kubibazo bisanzwe mugupima fibre.
(1) Kuki ikizamini cya fibre cyatsinzwe ariko paki iracyabura mugihe gikora neti?
Muguhitamo bisanzwe, abakoresha benshi bazakora amakosa agaragara, nko kutita cyane niba fibre yapimwe ari 50μm cyangwa 62.5 mm.
Ibisabwa kubiciro byinshi byo gutakaza agaciro ka fibre-aperture nini nini. Guhitamo nabi kwa optique ya test ya optique bizaganisha ku mpinduka zifatika. Kurugero, niba ihuza ryukuri ryapimwe ari 50μm fibre, naho ikizamini cyatoranijwe ni 62.5 mm, naho gusaba ni 100Base-FX, ukeka ko ibisubizo byikizamini ari 10dB, ikizamini kizabona ibisubizo bya PASS, kandi ibintu nyabyo bigomba kuba bitujuje ibyangombwa Kuberako birenze ibyemezo bya 6.3dB.
Ibi bisubiza ikibazo cyabanjirije iki, kandi ikizamini kiratsinda, ariko kuki amakuru azakomeza gutakaza paki.
(2) Kuki igipimo cya 10 cya Gigabit kitarashyigikirwa mugihe cyarenze 10 ya Gigabit?
Hariho abakoresha nkabo bazamura umugongo wurusobe. Bazazamura module yahindurana Seriveri. Birumvikana ko bazagerageza no gutakaza fibre murusobe. Birasa nkaho ntakibazo kiri muburyo. Fibre yageragejwe kugirango ihuze ibisabwa numuyoboro wa 10 wa Gigabit. , Igihombo kiri munsi yimipaka isanzwe, ariko ingaruka yibikorwa iracyari nziza.
Impamvu yo gusesengura ahanini ni uko uburyo bwagutse bwagutse bwa fibre optique idasuzumwa. Uburyo bwagutse bwububiko bwa fibre optique butandukanye bwerekana umurongo ntarengwa ushobora gutangwa mugihe runaka. Ninini yuburyo bwagutse, niko umuvuduko wo kwanduza intera runaka.Byoherejwe mumyaka yashize. Mubisanzwe, uburyo bwagutse ni buke, munsi ya 160. Nkigisubizo, umuvuduko ntushobora kwiyongera kuko intera ni ndende, nubwo igihombo cyemewe muriki gihe.
(3) Igihombo cyikizamini kigera kubisanzwe, kandi ntakibazo gihari muburyo bwagutse. Kuki hari ikibazo mubikorwa bifatika?
Turacyafite ubwumvikane buke mubizamini. Igihe cyose igihombo kirenganye, fibre ifatwa nkibyiza, ariko siko bimeze. Dufashe ibintu nkibi, igishushanyo gisanzwe gisaba igihombo cyo guhuza kuba 2.6dB. Gutakaza umutwe wa adapt birenze 0,75dB, ariko igihombo cyose cyo guhuza kiracyari munsi ya 2.6dB. Muri iki gihe, niba ugerageza gusa igihombo, ntushobora kubona ikibazo cya adapt, ariko mugukoresha imiyoboro nyayo, bizaterwa nikibazo cya adapt. Nkigisubizo, igipimo cyo kohereza biti cyiyongereye cyane.
