25Gbps 10km Duplex LC SFP28 Transceiver

wehewehe

Hoʻolālā ʻia nā transceivers SFP28 no ka hoʻohana ʻana i nā loulou 25-Gigabit Ethernet a hiki i 10km ma luna o ka Single Mode Fiber.

Ua kūpono nā transceivers me INF-8431 a me SFF-8472. No ka ʻike hou aku, e ʻoluʻolu e nānā iā INF-8431 a me SFF-8472.
