25Gbps 10km Duplex LC SFP28 Transceiver

Tlhaloso

Li-transceivers tsa SFP28 li etselitsoe ho sebelisoa ho lihokelo tsa 25-Gigabit Ethernet ho fihla ho 10km ho feta Single Mode Fiber.

Li-transceivers li lumellana le INF-8431 le SFF-8472. Bakeng sa tlhaiso-leseling e batsi, ka kopo sheba ho INF-8431 le SFF-8472.
