SFP (SMALL FORM PLUGGABLE) ishanduro yakakwidziridzwa yeGBIC (Giga Bitrate Interface Converter), uye zita rayo rinomiririra compact uye pluggable chimiro. Kuenzaniswa neGBIC, saizi yeSFP module yakaderedzwa zvakanyanya, inenge hafu yeGBIC. Iyi compact size inoreva kuti SFP inogona kugadzirwa neinopfuura kaviri nhamba yezviteshi pane imwechete pani, ichiwedzera zvakanyanya port density. Kunyangwe saizi yakaderedzwa, mabasa eSFP module anonyanya kufanana neGBIC uye anogona kusangana neakasiyana etiweki zvinodiwa. Kufambisa ndangariro, vamwe vanogadzira switch vanodaidzawo SFP modules "miniature GBIC" kana "MINI-GBIC".
1.25Gbps 1550nm 80 Duplex SFP LC DDM Module
Sezvo kudiwa kwefiber-to-the-home (FTTH) kuri kuramba kuchikura, kudiwa kwemaminiaturized optical signal transceivers (Transceivers) kuri kuramba kuchiwedzera kusimba. Dhizaini yeSFP module inotora izvi mukufunga kuzere. Iko kusanganiswa kwayo nePCB hakudi kuti pini inotengeswa, zvichiita kuti zvive nyore kushandisa paPC. Kusiyana neizvi, GBIC yakakura zvishoma muhukuru. Kunyangwe iri zvakare padivi pekubatana nedhiketi bhodhi uye isingade kushambadzira, density yayo yechiteshi haina kunaka seSFP.
Sechishandiso chekushandisa chinoshandura masaini egigabit emagetsi kuita zviratidzo zvemaziso, GBIC inotora dhizaini inopisa-inochinjika uye inochinjika zvakanyanya uye chiyero chepasirese. Nekuda kwekuchinjana kwayo, gigabit switch dzakagadzirwa neGBIC interface dzinotora chikamu chikuru chemusika. Nekudaro, iyo cabling yakatarwa yeGBIC port inoda kutariswa, kunyanya kana uchishandisa multimode fiber. Kushandisa chete multimode fiber kunogona kukonzera kuzara kweiyo transmitter uye inogamuchira, nekudaro ichiwedzera mwero wekukanganisa. Mukuwedzera, paunenge uchishandisa 62.5 micron multimode fiber, tambo yekugadzirisa patch cord inofanira kuiswa pakati peGBIC uye multimode fiber kuti ive nechokwadi chekubatanidza kure uye kushanda. Uku kutevedzera zviyero zveIEEE, kuve nechokwadi chekuti laser beam inoburitswa kubva panzvimbo chaiyo kure-pakati kusangana neIEEE 802.3z 1000BaseLX standard.
Muchidimbu, zvese zviri zviviri GBIC neSFP zvigadziriso zvinoshandiswa zvinoshandura masaini emagetsi kuita masaini masaini, asi SFP yakanyanya compact mukugadzira uye inokodzera mamiriro anoda yakakwirira port density. GBIC, kune rumwe rutivi, inotora nzvimbo mumusika nekuda kwekuchinjana kwayo uye kugadzikana. Paunenge uchisarudza, iwe unofanirwa kusarudza kuti ndeupi mhando yemodule yekushandisa zvichienderana nezvinodiwa chaizvo uye mamiriro.
