1. He aha ka module transceiver fiber optic QSFP?

- ʻO ka mea mua, pono kākou e hoʻomaopopo, he aha ka modula transceiver fiber optic SFP? ʻO ka modula transceiver fiber optic SFP (inoa piha: Small Form-factor Pluggable), pili i nā mea hana interface pūnaewele liʻiliʻi, modular, hot-swappable (transceivers) e kūpono i nā awa ma nā kuapo, nā routers, a me nā kikowaena, e ʻae ana i nā mea hana pūnaewele e hoʻopili ma o nā media like ʻole e like me nā kaula fiber optic a i ʻole nā ​​​​​​kaula keleawe no nā noi like ʻole, mai Gigabit Ethernet a i Fibre Channel.

- ʻO ka module transceiver fiber optic QSFP (Quad Small Form-factor Pluggable) kahi mea hoʻololi kaulana no ka pūnaewele wikiwiki, i hoʻohana ʻia no ke kamaʻilio ʻikepili wikiwiki i nā kikowaena ʻikepili, e kākoʻo ana i nā wikiwiki mai 10G a hiki i 400G+ ma ka hoʻohana ʻana i ʻehā mau ala like, e hiki ai ke hoʻonui i ka bandwidth ma mua o nā SFP maʻamau i kahi nui liʻiliʻi. ʻO nā ʻano koʻikoʻi e pili ana iā QSFP+, QSFP28, QSFP56, a me QSFP-DD, e kākoʻo ana kēlā me kēia i nā wikiwiki like ʻole (40G, 100G, 200G, 400G) ma ka hoʻonui ʻana i nā wikiwiki ʻikepili ma kēlā me kēia ala (10G, 25G, 50G, 100G) a me ka hoʻohana ʻana i nā pilina keleawe a fiber optic paha.

2. Pehea e hana ai ka QSFP?

- Hoʻokomo ʻia nā modula transceiver fiber optic QSFP i loko o nā lako pūnaewele, e hoʻololi ana i nā hōʻailona uila i nā hōʻailona optical a keleawe paha no ka hoʻoili ʻikepili wikiwiki, e hana ana ma ke ʻano he loulou koʻikoʻi no nā ʻoihana pūnaewele koi.

- Kākoʻo nā awa QSFP ma nā kuapo i nā ʻano pāpaho like ʻole:

+ DAC (Direct Attach Copper): ʻOi aku ka liʻiliʻi o ke kumukūʻai no nā pilina kikowaena-a-switch mamao pōkole (maʻamau <7m).
+ AOC (Active Optical Cable): Hoʻohana i ka fiber no nā mamao lōʻihi ma mua o ke keleawe akā me nā mea hoʻohui paʻa ma nā wēlau ʻelua.
+ Nā Modula Optical: Nā transceivers pluggable (e like me SR4, LR4, a i ʻole BiDi) e hoʻopili ana i nā kaula fiber optic maʻamau.
