Chii chinonzi QSFP?

Diki Form-factor Pluggable (SFP)ndeye compact, inopisa-pluggable network interface module fomati inoshandiswa kune ese ari maviri ekufonera uye data yekutaurirana maapplication. SFP interface pane networking hardware imodular slot ye media-specific transceiver, senge ye fiber-optic tambo kana tambo yemhangura.[1] Kubatsira kwekushandisa maSFP kana kuenzaniswa neyakagadziriswa mainterfaces (eg modular connectors muEthernet switches) ndeyekuti zviteshi zvega zvega zvinogona kuve nemhando dzakasiyana dzematransceivers sezvinodiwa, nehuwandu hunosanganisira optical line terminals, network makadhi, switch uye ma router.

QSFP, inomirira Quad Diki Fomu-factor Pluggable,ndizvorudzi rwe transceiver module inoshandiswa kumhanyisa-kumhanya dhata mumidziyo yetiweki, kunyanya munzvimbo dzedata uye yakakwirira-inoshanda komputa nharaunda.. Yakagadzirirwa kutsigira nzira dzakawanda (kazhinji ina) uye inokwanisa kubata data data kubva pa10 Gbps kusvika 400 Gbps, zvichienderana nemhando yemodule chaiyo.

Evolution yeQSFP:

Iyo QSFP chiyero chakashanduka nekufamba kwenguva, iine shanduro nyowani seQSFP+, QSFP28, QSFP56, uye QSFP-DD (Double Density) inopa yakawedzera data mazinga uye kugona. Aya mavhezheni matsva anovaka pamusoro peiyo yekutanga QSFP dhizaini yekusangana nekukura kuri kuda kwepamusoro bandwidth uye nekukurumidza kumhanya mumatiweki azvino.

Zvinokosha zveQSFP:

• High-Density:

QSFP modules dzakagadzirirwa kuve compact, zvichibvumira nhamba yepamusoro yekubatanidza munzvimbo diki.

• Inobatika:

Anogona kuiswa uye kubviswa mumudziyo paanenge akabatidzwa, pasina kukonzera kukanganisa kunetiweki.

• Multiple Channels:

QSFP modules inowanzove ine chiteshi ina, imwe neimwe inokwanisa kufambisa data, ichibvumira yakakwirira bandwidth uye data data.

• Yakasiyana-siyana Data Rates:

Mhando dzakasiyana dzeQSFP dziripo, dzakadai seQSFP+, QSFP28, QSFP56, uye QSFP-DD, inotsigira kumhanya kwakasiyana kubva ku40Gbps kusvika ku400Gbps uye mberi.

• Zvishandiso Zvakasiyana-siyana:

QSFP modules inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira data center interconnects, high-performance computing, uye telecommunication network.

• Copper uye Fiber Optic Sarudzo:

QSFP modules inogona kushandiswa netambo dzese dzemhangura (Direct Attach Cables kana DACs) uye fiber optic tambo.

40 Gbit/s (QSFP+)

QSFP+ ishanduko yeQSFP kutsigira mana 10 Gbit/s nzira dzakatakura gumi Gigabit Ethernet, 10GFC Fiber Channel, kana QDR InfiniBand. Iwo mana chiteshi anogona zvakare kusanganiswa kuita imwechete 40 Gigabit Ethernet link.

50 Gbit/s (QSFP14)

Iyo QSFP14 chiyero chakagadzirirwa kutakura FDR InfiniBand, SAS-3 kana 16G Fiber Channel.

100 Gbit/s (QSFP28)

Iyo QSFP28 standard yakagadzirirwa kutakura zana Gigabit Ethernet, EDR InfiniBand, kana 32G Fiber Channel. Dzimwe nguva iyi transceiver mhando inonziwo QSFP100 kana 100G QSFP nekuda kwekureruka.

200 Gbit/s (QSFP56)

QSFP56 yakagadzirirwa kutakura mazana maviri Gigabit Ethernet, HDR InfiniBand, kana 64G Fiber Channel. Kuwedzeredza kukuru ndeyekuti QSFP56 inoshandisa ina-level pulse-amplitude modulation (PAM-4) panzvimbo yekusadzoka-ku-zero (NRZ). Inoshandisa maitiro akafanana emuviri seQSFP28 (SFF-8665), nemagetsi emagetsi kubva kuSFF-8024 uye kudzokorora 2.10a yeSFF-8636. Dzimwe nguva iyi transceiver mhando inonzi 200G QSFP nekuda kwekureruka.

KCO Fiber inopa mhando yepamusoro ye fiber optic module SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. QSFP56, QSFP112, AOC, uye DAC, inogona kuenderana neakawanda emhando yekuchinja seCisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... nezvimwe. Ndokumbira ubate neboka redu rekutengesa kuti uwane rutsigiro rwakanyanya nezvehunyanzvi nyaya uye zvakare mutengo.
