Menene QSFP?

Ƙaramin Tsarin-Factor Mai Fitarwa (SFP)Tsarin tsarin haɗin hanyar sadarwa mai sauƙi ne, mai sauƙin haɗawa wanda ake amfani da shi don aikace-aikacen sadarwa da sadarwa na bayanai. Tsarin haɗin SFP akan kayan aikin sadarwa rami ne na modular don transceiver na musamman na kafofin watsa labarai, kamar na kebul na fiber-optic ko kebul na jan ƙarfe.[1] Fa'idar amfani da SFPs idan aka kwatanta da hanyoyin haɗin da aka gyara (misali masu haɗin modular a cikin maɓallan Ethernet) shine cewa tashoshin jiragen ruwa na mutum ɗaya za a iya sanye su da nau'ikan transceiver daban-daban kamar yadda ake buƙata, tare da yawancinsu sun haɗa da tashoshin layin gani, katunan cibiyar sadarwa, maɓallan da na'urorin sadarwa.

QSFP, wanda ke tsaye ga Quad Small Form-factor Pluggable,shinewani nau'in na'urar transceiver da ake amfani da ita don watsa bayanai cikin sauri a cikin na'urorin sadarwa, musamman a cibiyoyin bayanai da kuma yanayin kwamfuta mai aiki sosaiAn tsara shi ne don tallafawa tashoshi da yawa (yawanci huɗu) kuma yana iya sarrafa ƙimar bayanai daga 10 Gbps zuwa 400 Gbps, ya danganta da takamaiman nau'in module.

Juyin Halittar QSFP:

Ma'aunin QSFP ya ci gaba da bunƙasa a tsawon lokaci, tare da sabbin sigogi kamar QSFP+, QSFP28, QSFP56, da QSFP-DD (Double Density) waɗanda ke ba da ƙarin ƙimar bayanai da iyawa. Waɗannan sabbin sigogin sun gina bisa ƙirar QSFP ta asali don biyan buƙatun da ke ƙaruwa na babban bandwidth da sauri a cikin hanyoyin sadarwa na zamani.

Mahimman Sifofi na QSFP:

• Yawan Yawa:

An tsara na'urorin QSFP don su yi ƙanƙanta, wanda ke ba da damar samun adadi mai yawa na haɗi a cikin ƙaramin sarari.

• Mai iya haɗawa da zafi:

Ana iya saka su a cire su daga na'ura yayin da take kunnawa, ba tare da haifar da matsala ga hanyar sadarwar ba.

• Tashoshi da yawa:

Modules na QSFP yawanci suna da tashoshi huɗu, kowannensu yana da ikon aika bayanai, wanda ke ba da damar samun bandwidth mai yawa da ƙimar bayanai.

• Farashin Bayanai daban-daban:

Akwai nau'ikan QSFP daban-daban, kamar QSFP+, QSFP28, QSFP56, da QSFP-DD, suna tallafawa gudu daban-daban daga 40Gbps zuwa 400Gbps da sama.

• Aikace-aikace Masu Yawa:

Ana amfani da tsarin QSFP a cikin aikace-aikace iri-iri, gami da haɗin cibiyar bayanai, kwamfuta mai aiki sosai, da hanyoyin sadarwa.

• Zaɓuɓɓukan Tagulla da Fiber Optic:

Ana iya amfani da sassan QSFP tare da kebul na jan ƙarfe (Kafafu kai tsaye ko DAC) da kebul na fiber optic.

40 Gbit/s (QSFP+)

QSFP+ wani juyin halitta ne na QSFP wanda ke tallafawa tashoshi huɗu na Gbit/s guda 10 waɗanda ke ɗauke da Gigabit Ethernet guda 10, 10GFC Fiber Channel, ko QDR InfiniBand. Hakanan ana iya haɗa tashoshi huɗu zuwa haɗin Ethernet guda 40 Gigabit.

50 Gbit/s (QSFP14)

An tsara ma'aunin QSFP14 don ɗaukar FDR InfiniBand, SAS-3 ko 16G Fiber Channel.

100 Gbit/s (QSFP28)

An tsara ma'aunin QSFP28 don ɗaukar Gigabit Ethernet 100, EDR InfiniBand, ko 32G Fiber Channel. Wani lokaci ana kiran wannan nau'in transceiver da QSFP100 ko 100G QSFP don sauƙaƙawa.

200 Gbit/s (QSFP56)

An tsara QSFP56 don ɗaukar Gigabit Ethernet 200, HDR InfiniBand, ko 64G Fiber Channel. Babban haɓakawa shine cewa QSFP56 yana amfani da modulation na bugun jini-amplitude mai matakai huɗu (PAM-4) maimakon non-return-to-sifili (NRZ). Yana amfani da ƙayyadaddun bayanai na zahiri iri ɗaya kamar QSFP28 (SFF-8665), tare da ƙayyadaddun bayanai na lantarki daga SFF-8024 da bita 2.10a na SFF-8636. Wani lokaci ana kiran wannan nau'in transceiver da 200G QSFP don sauƙi.

Fiber na KCO yana samar da ingantaccen tsarin fiber optic SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, da DAC, waɗanda zasu iya dacewa da yawancin nau'ikan maɓallan kamar Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, …da sauransu. Da fatan za a tuntuɓi ƙungiyar tallace-tallace don samun mafi kyawun tallafi game da matsalar fasaha da farashi.
