    Specifications

    Generic Compatible 800G 2DR4 OSFP PAM4 Optical Transceiver Module (1310nm, 500m, 2x MPO-12 Connectors, SMF, 0℃ to +70℃, DDM)

     

    Generic Compatible 800G OSFP DR8 (2x 400G DR4)  transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 500m 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 FR4 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.

      We've had them running in production for a couple of weeks now and not a single glitch. For a fraction of the cost of the name-brand kit, these are an absolute bargain. I'd highly recommend them if you're looking to make your budget go further without compromising on quality.

      Purchased multiple units for a larger project. One thing that stood out was the consistency between modules. The optical readings were very similar across the batch, making deployment and validation much easier for our team.

      Bought a set of 4, all of them passed our internal BERT and optical sanity checks first try. No DOAs, no intermittent link drops.Would absolutely recommend for anyone looking to scale their 800G fabric without breaking the bank.

      Stumbled on this site while hunting for affordable 800G optics, eh. Took a chance, grabbed this 102705 twin‑port, and it's been running smooth for weeks now. For the price? Absolute steal, eh.
