    Arista OSFP-800G-2xSR4 Compatible 800GBASE-SR8 (2x400G SR4) OSFP Finned Top PAM4 Optical Transceiver Module (850nm, 100m, 2x MPO-12/APC Connectors, MMF, 0℃ to +70℃, DDM)

     

    Arista OSFP-800G-2xSR4 Compatible 800G OSFP SR8 (2x400G SR4) transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 50m over multi-mode fiber (MMF) with dual MPO-12 APC connectors. QSFPTEK manufactured 800GBASE-SR8 (2x 400GBASE SR4) OSFP complies with IEEE 802.3-2022 8x100GBASE-VR1 optical interface, IEEE 802.3ck-2022 8x100GAUI-1 C2M electrical interface, OSFP MSA Specification Rev 5.0 Type 2, 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 SR8 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4. The 800G SR8 OSFP is widely used for 800 gigabit Ethernet, 800G to 2x 400GBASE-SR4 breakout, data center and InfiniBand NDR applications.

    Easy 800G to 2x 400G breakout with MMFs

    The 800G OSFP 2SR4 module is designed with dual MPO-12/APC connectors, while each connector can connect to a physically separate 400G SR4 OSFP/QSFP-DD/QSFP112 module via an MTP/MPO-12 APC OM4 MMF. This enables 800G to 2x 400G breakout links without the need for using breakout fiber optic cables.

     

    Easy 800G to 2x 400G Breakout with OS2 SMFs

     

     

    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 about three weeks in production, though, these have been completely fine. Temperatures stay reasonable and the switches recognize them properly. At this point I’d probably order the same ones again instead of paying extra just for the original label.

      Honestly, I bought it initially because of its good value for money; it was significantly cheaper than the original manufacturer's. So far, I haven't encountered any problems, and the stability is OK. For me, this kind of product is all about "not having any issues," and so far, it has met that requirement.

      We're running an 800G SR8 module (2x400G SR4) in a high-density rack for internal switching. I tried it with different equipment from different sellers, and it still worked fine. It passed stress tests and continuous traffic runs without dropping.
