SFP (URUBUGA RWA GATO) ni verisiyo yazamuye ya GBIC (Giga Bitrate Interface Converter), kandi izina ryayo ryerekana uburyo bworoshye kandi bworoshye. Ugereranije na GBIC, ingano ya module ya SFP iragabanuka cyane, hafi kimwe cya kabiri cya GBIC. Ingano yoroheje isobanura ko SFP ishobora gushyirwaho inshuro zirenga ebyiri umubare wibyambu kumwanya umwe, byongera ubwinshi bwicyambu. Nubwo ingano yagabanutse, imikorere ya module ya SFP irasa cyane na GBIC kandi irashobora guhuza imiyoboro itandukanye. Kugirango borohereze kwibuka, bamwe mubakora switch nabo bita modul ya SFP "miniature GBIC" cyangwa "MINI-GBIC".
1.25Gbps 1550nm 80 Duplex SFP LC DDM Module
Mugihe icyifuzo cya fibre-to-home (FTTH) gikomeje kwiyongera, icyifuzo cya mini-mini optique ya transcevers (Transceivers) nacyo kiragenda gikomera. Igishushanyo cya SFP module ifata ibi mubitekerezo byuzuye. Gukomatanya kwayo na PCB ntibisaba kugurisha pin, bigatuma byoroha gukoresha kuri PC. Ibinyuranye, GBIC nini nini mubunini. Nubwo nayo ihuza impande zumuzunguruko kandi ntisaba kugurisha, ubwinshi bwicyambu cyayo ntabwo ari bwiza nka SFP.
Nkigikoresho cyimbere gihindura ibimenyetso byamashanyarazi ya gigabit mubimenyetso bya optique, GBIC ifata igishushanyo gishyushye kandi gishobora guhinduka cyane kandi mpuzamahanga. Bitewe no guhinduranya kwayo, gigabit yahinduwe yagizwe na interineti ya GBIC ifata igice kinini cyisoko. Nyamara, cabling ibisobanuro byicyambu cya GBIC bisaba kwitabwaho, cyane cyane iyo ukoresheje fibre fibre. Gukoresha fibre gusa ya fibre irashobora kuvamo kwiyuzuza kwa transmitter hamwe niyakira, bityo bikongera igipimo cyamakosa. Mubyongeyeho, mugihe ukoresheje fibre 62.5 ya micron fibre, umugozi wo guhindura uburyo ugomba gushyirwaho hagati ya GBIC na fibre ya multimode kugirango harebwe intera ihuza neza nibikorwa. Ibi ni ugukurikiza ibipimo bya IEEE, kwemeza ko urumuri rwa lazeri rusohoka ruvuye ahantu hatari hagati kugirango rwuzuze IEEE 802.3z 1000BaseLX.
Muncamake, byombi GBIC na SFP nibikoresho byimbere bihindura ibimenyetso byamashanyarazi mubimenyetso bya optique, ariko SFP irahuzagurika mugushushanya kandi irakwiriye kubintu bisaba ubwinshi bwicyambu. Ku rundi ruhande, GBIC ifata umwanya ku isoko kubera guhinduranya no guhagarara neza. Mugihe uhisemo, ugomba guhitamo ubwoko bwa module wakoresha ukurikije ibikenewe na ssenariyo.
