    Nyocha zuru ezu nke SFP ngwa anya modul interface egosi na components

    Oge nzipu: Jun-02-2020

    Ọsọ nke modul ngwa anya SFP + bụ: 10G SFP + transceiver anya bụ nkwalite nke SFP (mgbe ụfọdụ a na-akpọ “mini-GBIC”). A na-eji SFP eme ihe na Gigabit Ethernet na 1G, 2G, na 4G Fiber Channel. Iji mee mgbanwe na ọnụego data dị elu, SFP+ emebela nkwalite ihe nchebe elektrọnịkị na njirimara ndozi akara karịa SFP, wee chepụta nkọwapụta nhụta eletrik ọhụrụ.
