1. Mojule oa transceiver ke eng?
Li-module tsa Transceiver, joalo ka ha lebitso le fana ka maikutlo, li na le mahlakore a mabeli, 'me SFP le eona ke e' ngoe ea tsona.Lentsoe “transceiver” ke motsoako oa “mofetisi” le “moamoheli”.Ka hona, e ka sebetsa joalo ka transmitter le moamoheli ho theha puisano lipakeng tsa lisebelisoa tse fapaneng.E tsamaellanang le mojule ke seo ho thoeng ke pheletso, eo mojule oa transceiver o ka kenngoa ho eona.Li-module tsa SFP li tla hlalosoa ka botlalo likhaolong tse latelang.
1.1 SFP ke eng?
SFP e khutsufetse bakeng sa Small Form-factor Pluggable.SFP ke mojule o tloaelehileng oa transceiver.Li-module tsa SFP li ka fana ka likhokahano tsa lebelo la Gbit/s bakeng sa marang-rang le ho tšehetsa likhoele tsa multimode le singlemode.Mofuta o tloaelehileng haholo oa sebopeho ke LC.Ka pono, mefuta ea li-fiber e kopantsoeng e ka boela ea tsejoa ka 'mala oa SFP's pull tab, joalokaha ho bontšitsoe Setšoantšong sa B. Lesale la ho hula le leputsoa hangata le bolela cable ea mode e le 'ngoe,' me lesale la ho hula le bolela cable ea mefuta e mengata.Ho na le mefuta e meraro ea li-module tsa SFP tse hlophisitsoeng ho latela lebelo la phetisetso: SFP, SFP +, SFP28.
1.2 Phapano ke efe lipakeng tsa QSFP?
QSFP e emetse "Quad Form-factor plugable".QSFP e ka tšoara liteishene tse 'ne tse arohaneng.Joalo ka SFP, likhoele tsa mofuta o le mong le tse nang le mefuta e mengata li ka hokahanngoa.Seteishene se seng le se seng se ka fetisa litefiso tsa data ho fihla ho 1.25 Gbit/s.Ka hona, kakaretso ea tekanyo ea data e ka fihla ho 4.3 Gbit / s.Ha o sebelisa li-module tsa QSFP +, liteishene tse 'ne le tsona li ka kopanngoa.Ka hona, sekhahla sa data se ka fihla ho 40 Gbit / s.
