Mojule oa transceiver oa fiber ea optical SFP o sebetsa joang?

1. Mojule oa transceiver ke eng?

Dimojule tsa transceiver, jwalo ka ha lebitso le bontsha, di na le mahlakore a mabedi, mme SFP le yona ke e nngwe ya tsona. Lentswe "transceiver" ke motswako wa "transmitter" le "receiver". Ka hona, e ka sebetsa e le transmitter le receiver ho theha puisano pakeng tsa disebediswa tse fapaneng. Se tsamaellanang le mojule ke seo ho thweng ke pheletso, eo mojule wa transceiver o ka kenngwang ho yona. Dimojule tsa SFP di tla hlaloswa ka botlalo dikgaolong tse latelang.
1.1 SFP ke eng?

SFP e khutsufalitsoe bakeng sa Small Form-factor Pluggable. SFP ke module e tloaelehileng ea transceiver. Li-module tsa SFP li ka fana ka likhokahano tsa lebelo la Gbit/s bakeng sa marang-rang le ho tšehetsa li-fiber tsa multimode le singlemode. Mofuta o tloaelehileng oa sebopeho ke LC. Ka pono, mefuta ea li-fiber tse hokahanngoang e ka khetholloa ka 'mala oa tab ea ho hula ea SFP, joalo ka ha ho bontšitsoe ho Setšoantšo sa B. Lesale le leputsoa la ho hula hangata le bolela thapo ea mode e le 'ngoe, 'me lesale la ho hula le bolela thapo ea mode e mengata. Ho na le mefuta e meraro ea li-module tsa SFP tse arotsoeng ho latela lebelo la phetisetso: SFP, SFP+, SFP28.
1.2 Phapang ke efe pakeng tsa QSFP?

QSFP e emetse “Quad Form-factor Pluggable”. QSFP e ka tšoara liteishene tse 'ne tse arohaneng. Joalo ka SFP, likhoele tsa mode e le 'ngoe le tsa mode e mengata li ka hokahanngoa. Terene ka 'ngoe e ka fetisa sekhahla sa data ho fihlela ho 1.25 Gbit/s. Ka hona, sekhahla sohle sa data se ka fihla ho 4.3 Gbit/s. Ha ho sebelisoa li-module tsa QSFP+, literene tse 'ne le tsona li ka kopanngoa. Ka hona, sekhahla sa data se ka fihla ho 40 Gbit/s.
