He aha ka QSFP?

Hiki ke hoʻopili ʻia (SFP)ʻO ia ke ʻano hoʻopono pūnaewele paʻa, wela-pluggable i hoʻohana ʻia no ke kelepona a me nā noi kamaʻilio ʻikepili. ʻO kahi interface SFP ma ka ʻenehana pūnaewele he slot modular no kahi transceiver kikoʻī media, e like me ke kaula fiber-optic a i ʻole ke kaula keleawe.[1] ʻO ka maikaʻi o ka hoʻohana ʻana i nā SFP i hoʻohālikelike ʻia i nā pilina paʻa (e laʻa i nā mea hoʻohui modular i nā hoʻololi Ethernet) ʻo ia ka hiki ke hoʻolako ʻia nā awa pākahi me nā ʻano transceivers like ʻole e like me ka mea e pono ai, me ka hapa nui me nā laina laina optical, nā kāleka pūnaewele, nā hoʻololi a me nā mea ala.

ʻO QSFP, kahi e kū nei no Quad Small Form-factor Pluggable,ʻo iahe ʻano o ka transceiver module i hoʻohana ʻia no ka hoʻouna ʻana i ka ʻikepili kiʻekiʻe i nā polokalamu pūnaewele, ʻoi aku hoʻi i nā kikowaena ʻikepili a me nā kaiapuni computing hana kiʻekiʻe.. Hoʻolālā ʻia e kākoʻo i nā kaha he nui (maʻamau ʻehā) a hiki ke mālama i nā helu ʻikepili mai ka 10 Gbps a i 400 Gbps, ma muli o ke ʻano o ka module kikoʻī.

Hoʻomaka o QSFP:

Ua ulu ka maʻamau QSFP i ka manawa, me nā mana hou e like me QSFP +, QSFP28, QSFP56, a me QSFP-DD (Double Density) e hāʻawi ana i ka hoʻonui ʻana i nā helu a me nā hiki. Kūkulu ʻia kēia mau mana hou ma luna o ka hoʻolālā QSFP kumu no ka hoʻokō ʻana i nā koi ulu no ka bandwidth kiʻekiʻe a me nā wikiwiki wikiwiki i nā pūnaewele hou.

Nā mea nui o QSFP:

• Kiʻekiʻe-Density:

Hoʻolālā ʻia nā modula QSFP e paʻa, e ʻae i kahi helu kiʻekiʻe o nā pilina ma kahi liʻiliʻi liʻiliʻi.

• Hiki ke hoʻopili wela:

Hiki iā lākou ke hoʻokomo a hoʻoneʻe ʻia mai kahi hāmeʻa i ka wā e ʻā ana, me ka ʻole e hoʻopilikia i ka pūnaewele.

• Nā Kānāwai Nui:

Loaʻa i nā modula QSFP nā ʻehā ʻehā, hiki i kēlā me kēia mea ke hoʻouna i ka ʻikepili, e ʻae ana i ka bandwidth kiʻekiʻe a me nā helu data.

• Ka helu ʻikepili like ʻole:

Loaʻa nā ʻano like ʻole QSFP, e like me QSFP+, QSFP28, QSFP56, a me QSFP-DD, e kākoʻo ana i nā wikiwiki like ʻole mai 40Gbps a i 400Gbps a ʻoi aku.

• Nā mea hoʻohana like ʻole:

Hoʻohana ʻia nā modula QSFP i kahi ākea o nā noi, e pili ana i nā kikowaena kikowaena data, computing hana kiʻekiʻe, a me nā pūnaewele kelepona.

• Nā koho keleawe a me ka fiber optic:

Hiki ke hoʻohana ʻia nā modula QSFP me nā kaula keleawe ʻelua (Direct Attach Cables a i ʻole DAC) a me nā kaula fiber optic.

40 Gbit/s (QSFP+)

ʻO QSFP+ kahi hoʻololi o QSFP e kākoʻo i ʻehā mau kaha 10 Gbit/s e lawe ana i 10 Gigabit Ethernet, 10GFC Fiber Channel, a i ʻole QDR InfiniBand. Hiki ke hoʻohui pū ʻia nā kahawai 4 i kahi loulou 40 Gigabit Ethernet hoʻokahi.

50 Gbit/s (QSFP14)

Hoʻolālā ʻia ka maʻamau QSFP14 e lawe i ka FDR InfiniBand, SAS-3 a i ʻole 16G Fiber Channel.

100 Gbit/s (QSFP28)

Hoʻolālā ʻia ka maʻamau QSFP28 e lawe i 100 Gigabit Ethernet, EDR InfiniBand, a i ʻole 32G Fiber Channel. I kekahi manawa ua kapa ʻia kēia ʻano transceiver ʻo QSFP100 a i ʻole 100G QSFP no ka maʻalahi.

200 Gbit/s (QSFP56)

Hoʻolālā ʻia ʻo QSFP56 e lawe i 200 Gigabit Ethernet, HDR InfiniBand, a i ʻole 64G Fiber Channel. ʻO ka hoʻonui nui loa ʻo QSFP56 ka hoʻohana ʻana i ka modulation pulse-amplitude ʻehā-level (PAM-4) ma kahi o ka non-return-to-zero (NRZ). Hoʻohana ia i nā kikoʻī kino like me QSFP28 (SFF-8665), me nā kikoʻī uila mai SFF-8024 a me ka hoʻoponopono 2.10a o SFF-8636. I kekahi manawa ua kapa ʻia kēia ʻano transceiver ʻo 200G QSFP no ka maʻalahi.

Hāʻawi ʻo KCO Fiber i ke kūlana kiʻekiʻe o ka module fiber optic SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. ʻO QSFP56, QSFP112, AOC, a me DAC, hiki ke kūpono me ka hapa nui o nā mea hoʻololi e like me Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... etc. E ʻoluʻolu e kelepona me kā mākou hui kūʻai aku e loaʻa ke kākoʻo maikaʻi loa e pili ana i ka pilikia ʻenehana a me ke kumu kūʻai.
