    Arista Compatible 800GBASE-DR8 (2x400G DR4) OSFP Closed Finned Top PAM4 Optical Transceiver Module (1310nm, 100m, 2x MPO-12/APC Connectors, SMF, 0℃ to +70℃, DDM)

     

    Arista Compatible 800GBASE-DR8 (2x400G DR4) OSFP finned-top transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 100m over single-mode fiber (SMF) with dual MPO-12 APC connectors. QSFPTEK manufactured  800GBASE-DR8 (2x 400GBASE DR4) OSFP complies with IEEE 802.3cu-2021 8x100GBASE-DR optical interface, IEEE P802.3ck D3.0 8x100GAUI-1 C2M electrical interface, OSFP MSA HW Rev 4.1, CMIS Rev 5.0. DDM (digital diagnostics monitoring) function is supported on the 800G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the 2DR4 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 2x400GAUI-4 C2M electrical interface. The 800G DR8 OSFP is widely used for 800 gigabit Ethernet, 800G to 8x 100GBASE-DR, or 2x 400GBASE-DR4 breakout, data center and InfiniBand NDR applications.

    Easy 800G to 2x 400G breakout with MTP/MPO SMFs

    The 800G OSFP 2DR4 module is designed with dual MPO-12/APC connectors, while each connector can connect to a physically separate 400G DR4 OSFP/QSFP-DD/QSFP112 module via an MTP/MPO-12 APC OS2 SMF. This enables 800G to 2x 400G breakout links without the need for using breakout fiber optic cables.

    Finned-top Design to Ensure Long-term Stability

    Finned-top modules feature a heat sink on the top of transceiver or its laser. With superior thermal management, they are ideal for switches requiring efficient heat dissipation in long-term stable operation, such as Quantum-2 InfiniBand switch and the Spectrum-4 Ethernet switch. 

     

    Flat-top optics are used for adapters and Data Processing Units (DPUs), including the ConnectX-7 InfiniBand adapter and BlueField-3 DPU. Flat-top design can maximum optical coupling and transmission efficiency.

      After several weeks of continuous operation, the links have remained stable with no unexpected alarms or interruptions. Reliable performance so far.

      Big shoutout to Wendy! Honestly, I was a bit lost trying to work out which variant I needed for our Arista gear, and she walked me through it step by step. Super patient, super helpful. Module turned up, fired up straight away, no dramas. I'll definitely be ordering from these guys again, good on ya!

      My lab budget is practically non-existent, but I needed to get this Arista switch hooked up to handle some AI workloads. I only needed one of these OSFP modules, and your support team was actually nice about answering my noob questions. It’s been a few weeks now with zero downtime, so I figured I’d drop a good word. Thanks for not treating a small-timer like a hassle.

      Ces 800G OSFP, c'est du lourd. Reconnus direct sur nos équipements Arista, zéro réglage nécessaire. Ils chauffent un peu, mais rien d'alarmant, et le débit tient bien le 800G sans broncher. Quand tu compares le prix avec du OEM ? Ouais, on va en reprendre sans hésiter.

      I have to give a nod to their support team, especially the bloke who talked me through the compatibility check on this Arista OSFP-800G-2FR4 equivalent. I had an odd setup mixing Ethernet and InfiniBand and wasn't entirely sure which SKU to go for. He wasn't just trying to flog me something – he actually asked about my switch model, firmware version, and what I was doing with it, then confirmed this one would sort me out. Plugged it in, fired it up, and it's been absolutely flawless ever since. That sort of service is a rarity these days. I'll definitely be back for future builds, no question.
