Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Phakamisa ingqalasizinda yakho yenethiwekhi ibe sezingeni eliphezulu lokusebenza okuqhutshwa yi-AI nge-800GBASE-DR4 OSFP224 Transceiver Module yethu, eyenzelwe ukuhambisana kwe-plug-and-play okungaphazamiseki, okungu-100% ne-Mellanox/NVIDIA MMS4A20-XM800. Le module ye-optical yesizukulwane esilandelayo yenzelwe ngqo ukuhlangabezana nezidingo ze-bandwidth ezisezingeni eliphezulu kanye ne-ultra-low latency ze-InfiniBand XDR kanye ne-protocol ye-Ethernet yesizukulwane esilandelayo ye-800Gbps.
Isebenzisa ubuchwepheshe besimanje be-200G PAM4 modulation emizileni emine ezimele, le module inikeza i-bandwidth ehlanganisiwe engu-800Gb/s nge-Single-Mode Fiber (SMF) efinyelela kumamitha angu-500 nge-interface ejwayelekile ye-MPO-12/APC. Yakhelwe ku-RHS (Riding Heat Sink) noma ku-Flat Top form factors, inemiklamo ethuthukisiwe yokusatshalaliswa kokushisa ebalulekile kumaqoqo e-AI aqinile, apholiswe uketshezi, noma asebenza kahle kakhulu kanye namaswishi e-high-performance computing (HPC) (njengochungechunge lwe-Quantum-X800).
Kungakhathaliseki ukuthi wakha izindwangu zokuqeqesha ezinkulu ze-LLM (Large Language Model) noma uthuthukisa izikhungo zedatha yamafu e-hyperscale, le transceiver ye-XDR optical inikeza ukuthembeka okungenakunyakaziswa, ukulawulwa kwekhwalithi yezinga lezimboni, kanye nokusebenza kahle kwamandla okumangalisayo ukuze kuvikeleke amanethiwekhi akho optical esikhathini esizayo.
Incazelo Yomkhiqizo
I-NVIDIA/Mellanox MMS4A20-XM800 Iyahambisana ne-800G OSFP224 DR4 8x 200G PAM4 InfiniBand XDR Optical Transceiver Module (SMF, 1310nm, 500m, MPO-12/APC, DOM, RHS/Flat Top)
I-OSFP224-DR4-800G-FL iyahambisana ne-NVIDIA/Mellanox MMS4A20-XM800 futhi yenzelwe isizukulwane esilandelayo se-InfiniBand XDR kanye nokuxhumana kwesikhungo sedatha esinesivinini esikhulu. I-transceiver ye-800G DR4 isebenza ku-200Gb/s ngomzila ngamunye nge-modulation ye-PAM4 engu-4x 200Gb/s, isekela amabanga okudlulisa afinyelela kumamitha angu-500, okwenza kube kuhle kakhulu ekusetshenzisweni kwesikhungo sedatha esiseduze. Ihambisana nezindinganiso ze-OSFP MSA, CMIS Rev 5.2, IEEE 802.3dj, kanye ne-OIF 224G-VSR. Ukuqapha kwedijithali okwakhelwe ngaphakathi (DDM) kuvumela ukufinyelela kumapharamitha okusebenza wesikhathi sangempela.
Iqukethe ubuchwepheshe obuthuthukisiwe be-Broadcom 3nm DSP kanye ne-silicon photonics, le module inikeza i-BER ephansi kakhulu, ubuqotho besignali obuqinile, kanye nokuthembeka okuphezulu kwezixhumanisi ngesivinini esingu-800G ngenkathi ithuthukisa ubuningi bokuhlanganiswa kanye nokusebenza kahle kwamandla. Isetshenziselwa ukuxhumanisa amaswishi e-Quantum-X800 QM3x00 nama-transceivers e-OSFP 2x800Gb/s amabili e-twin-port kumakhadi e-ConnectX-8 mezzanine angu-800Gb/s kuzinhlelo ze-AI ezipholile ngoketshezi ze-DGX B300/GB300 noma amakhadi e-ConnectX-8 PCIe.
Qaphela: Ama-transceiver "aphezulu" manje abizwa ngokuthi "i-Integrated HeatSink" (IHS) njengoba ama-cooling fin ehlanganiswe phezulu kwensimbi yesixhumi se-OSFP futhi avame ukusetshenziswa kumaswishi apholiswe ngomoya. Ama-transceiver "aphezulu" manje abizwa ngokuthi "i-Riding Heat Sink" (RHS) njengoba ama-cooling fin ehamba phezu kwekhadi lenethiwekhi noma amakheji angaphakathi ezinhlelo. Lokhu kusetshenziselwa kokubili izinhlelo zokusebenza ezipholiswe ngomoya kanye nezipholiswe uketshezi ze-DGX, ConnectX-7, kanye ne-BlueField-3 DPUS.
