Kedu ka SFP modul transceiver optical fiber si arụ ọrụ?

1. Gịnị bụ transceiver modul?

Modul transceiver, dị ka aha ahụ na-egosi, bụ bidirectional, na SFP bụkwa otu n'ime ha.Okwu a bụ "transceiver" bụ ngwakọta nke "transmitter" na "onye nnata".Ya mere, ọ nwere ike ịrụ ọrụ dị ka onye na-ebufe na onye nnata iji guzobe nkwurịta okwu n'etiti ngwaọrụ dị iche iche.N'ikwekọ na modul bụ ihe a na-akpọ njedebe, nke enwere ike itinye modul transceiver.A ga-akọwapụta modul SFP n'ụzọ zuru ezu na isiakwụkwọ ndị na-esonụ.
1.1 Gịnị bụ SFP?

SFP dị mkpụmkpụ maka obere ụdị-factor Pluggable.SFP bụ modul transceiver ahaziri ahazi.Modul SFP nwere ike ịnye njikọ ọsọ Gbit/s maka netwọkụ ma kwado multimode na fibers singlemode.Ụdị interface a na-ahụkarị bụ LC.N'anya, a na-amata ụdị eriri na-ejikọta ya site na agba nke SFP's pull tab, dị ka egosiri na Figure B. Mgbanaka na-acha anụnụ anụnụ na-apụtakarị eriri otu mode, na mgbanaka mgbanaka pụtara multi-mode cable.Enwere ụdị modul SFP atọ nkewapụtara dị ka ọsọ nnyefe si dị: SFP, SFP+, SFP28.
1.2 Kedu ihe dị iche n'etiti QSFP?

QSFP na-anọchite anya "Quad Form-factor Pluggable".QSFP nwere ike ijide ọwa anọ dị iche iche.Dị ka SFP, enwere ike ijikọ ma otu-mode na multi mode fibers.Ọwa ọ bụla nwere ike ibunye ọnụego data ruo 1.25 Gbit/s.Ya mere, ngụkọta data ọnụego nwere ike ruo 4.3 Gbit/s.Mgbe ị na-eji modul QSFP+, ọwa anọ nwekwara ike jikọta.Ya mere, ọnụego data nwere ike ruo 40 Gbit/s.
