Ese fibre optique igomba gukoreshwa muburyo bubiri? Haba hari ibice bitandukanya fibre? Niba insimburangingo ya fibre igomba gukoreshwa kubiri, byanze bikunze ikirango nicyitegererezo kimwe? Cyangwa urashobora gukoresha uburyo ubwo aribwo bwose?
Igisubizo: Amashanyarazi meza akoreshwa muburyo bubiri nkibikoresho byo guhindura amafoto. Ariko, birashoboka kandi gukoresha optique ya transiporo na fibreGuhindura, fibre transibiver na SFP. Ihame, mugihe cyose optique yohereza imiyoboro yuburebure ari imwe, itumanaho rya fibre optique rishobora kugerwaho nuburyo bumwe bwo gukwirakwiza ibimenyetso no gushyigikira protocole runaka.
Mubisanzwe, fibre-fibre ebyiri (fibre ebyiri zisabwa kugirango itumanaho risanzwe) ntizigabanyijemo impera zihererekanyabubasha. Gusa transibiver ya fibre imwe (isaba fibre imwe kugirango itumanaho risanzwe) izagira ihererekanyabubasha nimpera yo kwakira.
Byaba ari fibre-fibre transceiver cyangwa fibre imwe ya fibre, irahuza gukoresha ibirango bitandukanye kubiri. Nyamara, ibipimo bitandukanye (megabits 100 na gigabytes) hamwe nuburebure butandukanye (1310 nm na 1300 nm) ntabwo bihuye. Mubyongeyeho, ndetse na transibre imwe ya fibre imwe yikirango kimwe hamwe na fibre ebyiri na fibre ebyiri ntishobora kuba imikoranire.
Ikwirakwizwa rya fibre fibre ifite icyambu cya TX (icyambu cyohereza) hamwe nicyambu cya RX (icyambu cyakira). Ibyambu byombi bisohora uburebure bumwe bwa 1310 nm, kandi kwakira nabyo ni 1310 nm, bityo rero parallel fibre ebyiri ihuzwa muguhuza. Umuyoboro umwe wa fibre ufite icyambu kimwe gusa, ushyira mubikorwa umurimo wohereza no gukora imirimo yakira . Ikoresha umurongo wa tekinike igabanya tekinoroji yohereza no kwakira ibimenyetso bibiri bya optique yuburebure butandukanye kuri fibre optique. Mubisanzwe bakoresha uburebure bwa 1310 nm na 1550 nm.
Ibirango bitandukanye bya optique ya transceiver ishyigikira protocole ya Ethernet. Barashobora kuvugana na transcevers yuburyo bumwe, ariko transcevers zimwe zongeraho imirimo imwe n'imwe (nka mirroring) kandi igashyigikira protocole zimwe. Kubireba urubanza ntabwo rushyigikiwe.
