E like me kā mākou e ʻike ai, loaʻa i ʻelua ʻano port nā hoʻololi Gigabit Ethernet: nā awa RJ45 a me nā awa SFP. Hiki i nā ʻano awa ʻelua ke lawe i ka Gigabit Ethernet transmission, no laila he aha ka ʻokoʻa ma waena o lākou? He aha ke ʻano o ka port Gigabit Ethernet switch e hoʻohana ʻia e ʻike i ka pilina Gigabit Ethernet?

He aha ke awa RJ45 ma ke kuapo Gigabit Ethernet?
ʻO ke awa RJ45 o ka hoʻololi Gigabit Ethernet he awa i kūkulu ʻia. Hiki ke hoʻohana ʻia kēia ʻano awa no ka loaʻa ʻana o ke kikowaena ma ke kikowaena data, LAN, a me ka uplink o nā hoʻololi papapihi a i ʻole Gigabit i nā noi bandwidth desktop. Ke hoʻohui ʻia ʻelua mau hoʻololi Gigabit Ethernet, hoʻohana mau ʻia nā kaula wili-wili maʻamau, e like me CAT-5, CAT-5, CAT-6, a me CAT-6 mau mea lele lele.

He aha ke awa SFP ma ka hoʻololi Gigabit Ethernet?

Ua kapa ʻia ʻo port SFP (liʻiliʻi wela-swappable interface) mini-GBIC port, ʻo 1G ka nui o ka hoʻouna ʻana, a hiki iā ia ke kākoʻo i ka loulou keleawe a i ʻole ka loulou optical (ma Ethernet, SFP port rate he 1Gbit/s, ma ka fiber channel system In, hiki i ka helu port SFP ke hiki i 4Gbit/s). I ka hoʻokomo ʻana i kahi modula pili uila i loko o kahi awa SFP, hoʻopili maʻamau ia me ke kelepona pūnaewele (Cat5/Cat5e/Cat6) no ka lawe ʻana i ka ʻikepili. Ke hoʻokomo ʻia ka module port optical i loko o ke awa SFP, pono ʻoe e hoʻohana i ka LC jumper e hoʻouna i mea e hiki ai ke hoʻokō i ka lawe mamao lōʻihi. Eia kekahi, i nā noi e like me nā kikowaena ʻikepili a me nā ʻenehana wahi kūloko (LAN), loaʻa i ka port SFP o ka hoʻololi ʻana i kahi hana adaptive 100/1000Mbps.

RJ45 awa VS SFP awa

Mai ka manaʻo i luna, ʻo ka hana o ke awa RJ45 a me ke awa SFP he mea like ia; akā mai ke kumu kūʻai, ʻoi aku ka kiʻekiʻe o ke kumukūʻai uea o ke awa SFP. Eia nō naʻe, pono mau ke awa SFP no ka mea hiki iā ia ke kākoʻo i ʻelua ʻano o nā modula port uila SFP a me nā modula port optical SFP. Ke hoʻohana nei i nā modula optical port optical SFP, ʻoi aku ka lōʻihi o ka hoʻouna ʻana ma mua o nā awa RJ45. Ma nā noi kūpono, loaʻa iā ia ke kiʻekiʻe kiʻekiʻe, a ʻoi aku ka kiʻekiʻe o ka scalability.
