Bu sayede bir QSFP+ mod\u00fclden 4 ayr\u0131 noktadaki SFP+ mod\u00fcle duplex fiber ba\u011flant\u0131 sa\u011flanabilir.<\/p>\n

K\u0131saca \u00f6zetlemek gerekirse QSFP, SFP transceiverlar\u0131n yeterli geli\u015fme h\u0131z\u0131n\u0131 sa\u011flayamamas\u0131 nedeni ile, daha y\u00fcksek h\u0131zlara ula\u015fmak i\u00e7in geli\u015ftirilmi\u015f bir standartt\u0131r.

Bu h\u0131zlar\u0131 sa\u011flamak i\u00e7in QSFP mod\u00fcller d\u00f6rt vericinin sinyallerini birle\u015ftirerek tek core fiber \u00fczerinden iletebilir veya 8 core MPO konekt\u00f6r<\/strong>ler kullan\u0131larak her bir al\u0131c\u0131 ve verici sinyalleri farkl\u0131 corelar \u00fczerinden ta\u015f\u0131nabilir. Bunun yan\u0131nda, MPO konekt\u00f6rl\u00fc QSFP mod\u00fcllerden, ayn\u0131 h\u0131za kar\u015f\u0131l\u0131k gelen d\u00f6rt farkl\u0131 SFP mod\u00fcle de ba\u011flant\u0131 sa\u011flanabilir.<\/p>\n
