Ni gute module ya transceiver ya fiber optique SFP ikora?

1. Module ya transceiver ni iki?

Module za Transceiver, nk'uko izina ribigaragaza, zifite icyerekezo cy'ibice bibiri, kandi SFP nayo ni imwe muri zo. Ijambo "transceiver" ni uruvange rwa "transmitter" na "receiver". Kubwibyo, ishobora gukora nk'itumanaho n'itumanaho kugira ngo habeho itumanaho hagati y'ibikoresho bitandukanye. Bijyanye na module ni icyitwa impera, aho module ya transceiver ishobora gushyirwamo. Module za SFP zizasobanurwa birambuye mu bice bikurikira.
1.1 SFP ni iki?

SFP ni ijambo rihinnye rivuga "Small Form-factor Pluggable". SFP ni module ya transceiver isanzwe. Module za SFP zishobora gutanga umuvuduko wa Gbit/s ku miyoboro no gushyigikira fibre za multimode na singlemode. Ubwoko bw'interface bukunze gukoreshwa cyane ni LC. Mu buryo bugaragara, ubwoko bwa fibre bushobora no kumenyekana hakurikijwe ibara rya tab ya SFP yo gukurura, nk'uko bigaragara ku Ishusho ya B. Impeta y'ubururu yo gukurura akenshi bivuze insinga ya single-mode, naho impeta yo gukurura igasobanura insinga ya multi-mode. Hari ubwoko butatu bwa module za SFP zishyizwe mu byiciro hakurikijwe umuvuduko wo kohereza: SFP, SFP+, SFP28.
1.2 Ni irihe tandukaniro riri hagati ya QSFP?

QSFP isobanura "Quad Form-factor Pluggable". QSFP ishobora gufata imiyoboro ine itandukanye. Kimwe na SFP, imiyoboro yombi ya mode imwe na multi-mode irashobora guhuzwa. Buri muyoboro ushobora kohereza amakuru agera kuri 1.25 Gbit/s. Kubwibyo, igipimo cy'amakuru cyose gishobora kugera kuri 4.3 Gbit/s. Mu gukoresha module za QSFP+, imiyoboro ine ishobora no guhuzwa. Kubwibyo, igipimo cy'amakuru gishobora kugera kuri 40 Gbit/s.
