Nigute optique fibre transceiver module SFP ikora?

1. Module ya transceiver ni iki?

Transceiver modules, nkuko izina ribigaragaza, ni ibyerekezo byombi, kandi SFP nayo nimwe murimwe.Ijambo "transceiver" ni ihuriro rya "transmitter" n "" uwakira ".Kubwibyo, irashobora gukora nka transmitter hamwe niyakira kugirango ishyireho itumanaho hagati yibikoresho bitandukanye.Guhuza na module nicyo bita iherezo, aho module ya transceiver ishobora kwinjizwamo.Module ya SFP izasobanurwa muburyo burambuye mubice bikurikira.
1.1 SFP ni iki?

SFP ni ngufi kuri Ntoya-Ikintu Cyoroshye.SFP ni module isanzwe ya transceiver.SFP modules irashobora gutanga Gbit / s yihuta kumuyoboro kandi igashyigikira fibre ya multimode na singlemode.Ubwoko bwa interineti busanzwe ni LC.Mu buryo bugaragara, ubwoko bwa fibre ihujwe irashobora kandi kumenyekana nibara ryikurura rya SFP, nkuko bigaragara ku gishushanyo B. Impeta yo gukurura ubururu ubusanzwe isobanura umugozi umwe, naho impeta ikurura bisobanura insinga nyinshi.Hariho ubwoko butatu bwa modul ya SFP yashyizwe mubikorwa ukurikije umuvuduko wo kohereza: SFP, SFP +, SFP28.
1.2 Ni irihe tandukaniro riri hagati ya QSFP?

QSFP isobanura “Quad Form-factor Plugable”.QSFP irashobora gufata imiyoboro ine itandukanye.Kimwe na SFP, byombi-moderi imwe na fibre-fibre irashobora guhuzwa.Buri muyoboro urashobora kohereza ibipimo byamakuru kugeza kuri 1.25 Gbit / s.Kubwibyo, igipimo rusange cyamakuru gishobora kugera kuri 4.3 Gbit / s.Iyo ukoresheje QSFP + modules, imiyoboro ine nayo irashobora guhuzwa.Kubwibyo, igipimo cyamakuru gishobora kugera kuri 40 Gbit / s.
