NVIDIA MMS4A20-XM800 Single Port Transceiver 800gbps Osfp Dr4 Mpo Apc 1310nm Smf Up To 500m Rhs
Overview The NVIDIA Mms4a20 Is An 800gb/s Single-mode Optical Transceiver Supporting The Xdr 800gb/s Infiniband Protocol. It Is Used To Link The Quantum-x800 Qm3x00 Switches Using Twin-port Osfp 2x800gb/s Transceivers To The Dual 800gb/s Connectx-8 Mezzanine Card In Liquid Cooled System And Connectx-8 Pcie Cards. Osfp Cages Are Located In The Compute Tray Front-panel.
The Line Rate Is 200gb/s Using Pulse Amplitude Modulation Of 4- Channels Denoted As 200g-pam4, Enabling Two Data Bits To Be Transferred Per Clock Pulse. The Electrical Configuration Is 4-channels Of 200g-pam4. The Optical Configuration Has One, 500-meter, Datacenter Reach, 4-channel (dr4), 800gb/s Optical Connector, And Is A Single Multiple Push-on 12-fiber, Angled Polished Connector Or Mpo-12/apc. One Mpo-12/apc Optical Connector Is Used Per Transceiver.
Based On 9-mm, Single Mode Fibers, The 800g Transceiver Can Reach Up To 500-meters, Supporting Large Gpu Clusters.
The Plug Formfactor Is A Single-port Osfp (octal Small Formfactor Plug) And Uses A Riding Heat Sink (rhs) Or Flat-top Osfp Connector With The Cooling Fins On Top Of The Connectx-8 Cage. This Can Also Be Used In Liquid-cooled Riding Heat Sink (rhs) Applications.
NVIDIAS Transceivers Guarantee Optimal Operation In NVIDIA End-to- End Infiniband Systems And Rigorous Production Testing Ensures The Lowest Bit Error Rates, Low-latency, And Best Out-of-the-box Installation Experience, Performance, And Durability.
