He aha ka QSFP?

Hiki ke hoʻopili ʻia ke ʻano liʻiliʻi (SFP)he ʻano modula interface pūnaewele liʻiliʻi a hoʻopili wela i hoʻohana ʻia no nā noi kamaʻilio kelepona a me nā noi kamaʻilio ʻikepili. ʻO kahi interface SFP ma nā lako pūnaewele he slot modular no kahi transceiver media-specific, e like me ke kaula fiber-optic a i ʻole ke kaula keleawe. [1] ʻO ka pōmaikaʻi o ka hoʻohana ʻana i nā SFP i hoʻohālikelike ʻia me nā interface paʻa (e laʻa me nā mea hoʻohui modular i nā kuapo 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 e komo pū ana me nā kikowaena laina optical, nā kāleka pūnaewele, nā kuapo a me nā mea hoʻohele.

ʻO QSFP, ʻo ia hoʻi ke kū nei no Quad Small Form-factor Pluggable,ʻo iahe ʻano modula transceiver i hoʻohana ʻia no ka hoʻoili ʻikepili wikiwiki i nā polokalamu pūnaewele, ʻoi aku hoʻi i nā kikowaena ʻikepili a me nā wahi kamepiula hana kiʻekiʻeUa hoʻolālā ʻia e kākoʻo i nā kahawai he nui (ʻehā maʻamau) a hiki ke lawelawe i nā helu ʻikepili mai 10 Gbps a i 400 Gbps, ma muli o ke ʻano module kikoʻī.

Ka ulu ʻana o QSFP:

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

Nā Hiʻohiʻona Koʻikoʻi o QSFP:

• Kiʻekiʻe-Density:

Ua hoʻolālā ʻia nā modula QSFP e liʻiliʻi, e ʻae ana i ka nui o nā pilina ma kahi wahi liʻiliʻi.

• Hiki ke hoʻopili ʻia me ka wela:

Hiki ke hoʻokomo a wehe ʻia lākou mai kahi hāmeʻa i ka wā e hoʻā ʻia ana, me ka ʻole o ka hoʻopilikia ʻana i ka pūnaewele.

• Nā Kanal He Nui:

ʻO nā modula QSFP maʻamau he ʻehā mau kahawai, hiki i kēlā me kēia ke hoʻouna i ka ʻikepili, e ʻae ana i ka bandwidth kiʻekiʻe a me nā wikiwiki ʻikepili.

• Nā ʻIkepili like ʻole:

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

• Nā Hoʻohana Kūikawā:

Hoʻohana ʻia nā modula QSFP i nā ʻano noi like ʻole, me nā pilina kikowaena ʻikepili, ka helu hana kiʻekiʻe, a me nā pūnaewele kelepona.

• Nā Koho Keleawe a me Fiber Optic:

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

40 Gbit/s (QSFP+)

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

50 Gbit/s (QSFP14)

Ua hoʻolālā ʻia ke kūlana QSFP14 e halihali i ka FDR InfiniBand, SAS-3 a i ʻole 16G Fiber Channel.

100 Gbit/s (QSFP28)

Ua hoʻolālā ʻia ke kūlana 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)

Ua hoʻolālā ʻia ʻo QSFP56 e lawe i 200 Gigabit Ethernet, HDR InfiniBand, a i ʻole 64G Fiber Channel. ʻO ka hoʻonui nui loa, ʻo ia ka hoʻohana ʻana o QSFP56 i ka modulation pulse-amplitude ʻehā pae (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 hou ʻana 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. QSFP56, QSFP112, AOC, a me DAC, hiki ke kūlike me ka hapa nui o nā brand switch e like me Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, … etc. E ʻoluʻolu e hoʻokaʻaʻike me kā mākou hui kūʻai aku e loaʻa ke kākoʻo maikaʻi loa e pili ana i ka pilikia loea a me ke kumukūʻai.
