Chii chinonzi QSFP?

Chinodhonzwa Chidiki CheForm-factor (SFP)imhando ye network interface module ine complex, hot-pluggable inoshandiswa pamafoni nepama application ekutaurirana data. SFP interface pa networking hardware imodular slot ye media-specific transceiver, senge fiber-optic cable kana copper cable.[1] Kubatsira kwekushandisa SFPs zvichienzaniswa ne fixed interfaces (semuenzaniso modular connectors mu Ethernet switches) ndekwekuti ma ports ega ega anogona kuve ne transceivers dzakasiyana sezvinodiwa, mazhinji acho anosanganisira optical line terminals, network cards, switches uye routers.

QSFP, iyo inomiririra Quad Small Form-factor Pluggable,irimhando yemodule yetransceiver inoshandiswa pakutumira data nekukurumidza mumidziyo yekubatanidza, kunyanya munzvimbo dzedata nenzvimbo dzemakombiyuta dzinoshanda zvakanyanyaYakagadzirirwa kutsigira nzira dzakasiyana-siyana (dzinowanzova ina) uye inogona kubata huwandu hwedata hunotangira pa10 Gbps kusvika pa400 Gbps, zvichienderana nerudzi rwemodule chaiyo.

Kushanduka kweQSFP:

Mwero weQSFP wakashanduka nekufamba kwenguva, neshanduro itsva dzakadai seQSFP+, QSFP28, QSFP56, uye QSFP-DD (Double Density) dzichipa huwandu hwedata rakawanda uye kugona kwadzo. Idzi shanduro itsva dzinobva padhizaini yeQSFP yekutanga kuti ikwanise kuzadzisa zvinodiwa zviri kukura zvebandwidth yakakwira uye kumhanya nekukurumidza mumanetwork emazuva ano.

Zvinhu Zvikuru zveQSFP:

• Kuwanda Kwevanhu:

Ma module eQSFP akagadzirwa kuti ave madiki, zvichibvumira huwandu hwakawanda hwekubatanidza munzvimbo diki.

• Zvinopisa-Zvinodhonzwa:

Zvinogona kuiswa uye kubviswa kubva mumudziyo kana wakabatidzwa, pasina kukonzera nyonganyonga kunetiweki.

• Nzira Dzakawanda:

Ma module eQSFP anowanzova nemigero mina, imwe neimwe inokwanisa kutumira data, zvichibvumira bandwidth yakakwira uye mwero wedata.

• Mitengo yeData Yakasiyana-siyana:

Kune mhando dzakasiyana dzeQSFP, dzakadai seQSFP+, QSFP28, QSFP56, uye QSFP-DD, dzinotsigira kumhanya kwakasiyana kubva pa40Gbps kusvika ku400Gbps zvichikwira.

• Mashandisirwo Anoshandiswa Pakuchinja-chinja:

Ma module eQSFP anoshandiswa mumhando dzakasiyana-siyana dzemashandisirwo, kusanganisira data center interconnects, high-performance computing, uye telecommunications networks.

• Sarudzo dzeCopper neFiber Optic:

Mamodule eQSFP anogona kushandiswa netambo dzemhangura (Direct Attach Cables kana DACs) uye tambo dzefiber optic.

40 Gbit/s (QSFP+)

QSFP+ ishanduko yeQSFP inotsigira nzira ina dze10 Gbit/s dzine 10 Gigabit Ethernet, 10GFC Fiber Channel, kana QDR InfiniBand. Nzira ina idzi dzinogonawo kubatanidzwa kuita imwe chete ye40 Gigabit Ethernet link.

50 Gbit/s (QSFP14)

Chiyero cheQSFP14 chakagadzirirwa kutakura FDR InfiniBand, SAS-3 kana 16G Fiber Channel.

100 Gbit/s (QSFP28)

Chiyero cheQSFP28 chakagadzirirwa kutakura 100 Gigabit Ethernet, EDR InfiniBand, kana 32G Fiber Channel. Dzimwe nguva rudzi urwu rwetransceiver runonziwo QSFP100 kana 100G QSFP nekuda kwekureruka.

200 Gbit/s (QSFP56)

QSFP56 yakagadzirirwa kutakura 200 Gigabit Ethernet, HDR InfiniBand, kana 64G Fiber Channel. Chinhu chikuru chakawedzerwa ndechekuti QSFP56 inoshandisa four-level pulse-amplitude modulation (PAM-4) pachinzvimbo che non-return-to-zero (NRZ). Inoshandisa zvakafanana neQSFP28 (SFF-8665), ine magadzirirwo emagetsi kubva kuSFF-8024 uye revision 2.10a yeSFF-8636. Dzimwe nguva rudzi urwu rwetransceiver runonzi 200G QSFP nekuda kwekureruka.

KCO Fiber inopa fiber optic module yemhando yepamusoro SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, uye DAC, zvinogona kushanda nemagetsi akawanda akadai seCisco, Huawei, H3C, ZTE, Juniper, Arista, HP, …nezvimwewo. Ndapota taura nechikwata chedu chekutengesa kuti uwane rubatsiro rwakanakisisa nezvenyaya dzehunyanzvi pamwe nemutengo.
