o QSFP28 optical modules aia ma laila?

Hiki ke ʻōlelo ʻia ʻo QSFP28 optical module he hanauna hou o ka module optical, i makemake nui ʻia e nā mea hana he nui ma muli o kona mau mea maikaʻi e like me ka liʻiliʻi liʻiliʻi, ke kiʻekiʻe o ke awa kiʻekiʻe, a me ka hoʻohana haʻahaʻa haʻahaʻa.No laila, he aha nā ʻano o nā modula optical QSFP8 i laila?
ʻIke ʻia ʻo QSFP28 optical module he 100G optical module.He mea nui ia o ka pūnaewele 100G.Hoʻohana nui ʻia i nā noi 100G Ethernet a me EDR InfiniBand.Hoʻohana ʻo ia i ʻehā 25Gbit/s kaila hoʻouna e hoʻouna i ka ʻikepili.
ʻO kēia ka hoʻolauna ʻana i nā ʻano o QSFP28 optical modules:
1: QSFP28SR4 module optical
ʻIke ʻia ʻo QSFP28SR4 optical module ʻo 100GBASE-SR4QSFP28 optical module.Ma muli o ka hoʻohana ʻana o ka hapa nui o nā kikowaena ʻikepili i ka fiber optical multi-mode, ua hoʻomohala ʻo IEEE i kahi maʻamau no 100GQSFP28 module optical e kākoʻo pono ana i nā noi hoʻouna pōkole pōkole multi-mode: 100GBASE-SR4.Hoʻohana ʻo QSFP28SR4 optical module i ka MTP interface (8 cores), ʻo ka mamao o ka lawe ʻana i ka wā i hoʻohana ʻia me OM3 multimode fiber he 70m, a ʻo ka mamao o ka lawe ʻana i ka wā i hoʻohana ʻia me OM4 multimode fiber he 100m, kūpono no ka hoʻouna ʻana i kahi mamao pōkole, QSFP28SR4 optical module no ka parallel 100G. Loaʻa i ka module optical nā mea maikaʻi o ke awa kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.

ʻO nā hiʻohiʻona huahana penei:
(100GQSFP28SR4100m kōpili ʻōpika)
