SFP (KUTHANDIZA KWA FOMU ANG'ONO) ndi mtundu wokwezedwa wa GBIC (Giga Bitrate Interface Converter), ndipo dzina lake limayimira mawonekedwe ake ophatikizika komanso omangika. Poyerekeza ndi GBIC, kukula kwa gawo la SFP kumachepetsedwa kwambiri, pafupifupi theka la GBIC. Kukula kophatikizikaku kumatanthauza kuti SFP ikhoza kukhazikitsidwa ndi kuchuluka kwa madoko pagawo lomwelo, ndikuchulukitsa kuchuluka kwa madoko. Ngakhale kukula kumachepetsedwa, ntchito za module ya SFP ndizofanana ndi GBIC ndipo zimatha kukwaniritsa zosowa zosiyanasiyana za intaneti. Kuti muthandizire kukumbukira, ena opanga ma switch amatchanso ma module a SFP "miniature GBIC" kapena "MINI-GBIC".
1.25Gbps 1550nm 80 Duplex SFP LC DDM module
Pamene kufunikira kwa fiber-to-the-home (FTTH) kukukulirakulira, kufunikira kwa ma transceivers optical optical transceivers (Transceivers) akukulirakulira. Mapangidwe a module ya SFP amalingalira izi mokwanira. Kuphatikiza kwake ndi PCB sikufuna kugulitsa pini, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito pa PC. Mosiyana ndi izi, GBIC ndiyokulirapo pang'ono. Ngakhale imalumikizananso ndi gulu ladera ndipo sichifuna kugulitsa, kachulukidwe kake ka doko sikwabwino ngati SFP.
Monga chipangizo cholumikizira chomwe chimasintha ma siginecha amagetsi a gigabit kukhala ma siginecha owoneka bwino, GBIC imatenga mawonekedwe osinthika komanso osinthika kwambiri komanso muyezo wapadziko lonse lapansi. Chifukwa cha kusinthasintha kwake, ma switch a gigabit opangidwa ndi mawonekedwe a GBIC amakhala ndi gawo lalikulu pamsika. Komabe, ma cabling a doko la GBIC amafunikira chidwi, makamaka mukamagwiritsa ntchito ulusi wa multimode. Kugwiritsa ntchito ma multimode fiber okha kumatha kubweretsa kuchuluka kwa chotumizira ndi cholandila, potero kumakulitsa kuchuluka kwa zolakwika pang'ono. Kuphatikiza apo, mukamagwiritsa ntchito 62.5 micron multimode fiber, chingwe chosinthira modekha chiyenera kukhazikitsidwa pakati pa GBIC ndi fiber multimode kuti muwonetsetse mtunda wolumikizana bwino ndi magwiridwe antchito. Uku ndikutsata miyezo ya IEEE, kuwonetsetsa kuti mtengo wa laser watulutsidwa pamalo eni ake apakati kuti ukwaniritse muyezo wa IEEE 802.3z 1000BaseLX.
Mwachidule, zonse za GBIC ndi SFP ndi zida zolumikizirana zomwe zimatembenuza ma siginecha amagetsi kukhala ma siginecha owoneka bwino, koma SFP imakhala yophatikizika pamapangidwe ndipo ndiyoyenera pazochitika zomwe zimafuna kuchulukira kwa doko. GBIC, kumbali ina, ili ndi malo pamsika chifukwa cha kusinthasintha kwake komanso kukhazikika. Posankha, muyenera kusankha mtundu wa gawo lomwe mungagwiritse ntchito potengera zosowa zenizeni ndi zochitika.
