    Specifications

    Arista Compatible 800GBASE-DR8 (2x400G DR4) LPO (Linear-drive Pluggable Optics) OSFP PAM4 Optical Transceiver Module (1310nm, 500m, Dual MPO-12 APC, SMF, 0°C to 70°C, DDM)

     

    Arista Compatible 800GBASE-DR8 (2x400G DR4) OSFP Linear-drive Pluggable Optics (LPO) 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 LPO module complies with LPO MSA 100G-DR-LPO Draft Rev 0.5 optical specifications, CEI-112G-LINEAR-PAM4 electrical specifications, CMIS Rev 4.0 and RoHS. 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 DR8 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4. The 800G DR8 OSFP is widely used for 800 gigabit Ethernet, 800G to 8x 100GBASE-DR, or 2x 400GBASE-DR4 breakout, and data center interconnect.

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

    The 800G OSFP 2DR4 LPO 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.

    Revolutionize Data Center Connectivity with LPO

    Traditional DSPs are a bottleneck for power and latency. Linear-Drive Pluggable Optics (LPO) removes this bottleneck by using linear-drive chips instead, enabling next-generation high-speed networks that are both extremely power-efficient and low-latency—critical for scaling AI and compute infrastructure.

    Revolutionize Data Center Connectivity with LPO

     

     

    Remove DSP to Achieve Lower Power and Latency

    DSP Module:

    Pros: Excellent performance and interoperability, reliable for diverse, long-reach applications.

    Cons: Higher power consumption and cost due to complex DSP circuitry.

    LPO Module:

    Pros: Drastically lower power and latency, ideal for short-reach, power-sensitive environments like AI clusters.

    Cons: Interoperability relies heavily on the host switch, requiring a more ecosystem-specific approach.

    8x 100Gbps PAM4 Modulation Technology

    Utilize 8x electrial lanes and 8x optical lanes modulated at 100G PAM-4 per lane. On the output side, it convert 8x 106.25Gb/s electrical signal to 8x 106.25Gb/s optical signals. On the receiver side, it convert 8x 100Gb/s optical signal to 8x 100Gb/s electrical signals.
