    Generic Compatible 800GBASE-DR8 (2x400G DR4) SiPh (Silicon Photonics) OSFP Finned Top PAM4 Optical Transceiver Module (1310nm, 500m, Dual MPO-12 APC, SMF, 0°C to 70°C, DDM)

     

    Generic Compatible 800GBASE-DR8 (2x400G DR4) OSFP Silicon Photonics (SiPh) finned-top 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 OSFP MSA and CMIS, 8x106.25Gbps (53.125GBd PAM4) electrical interface, 8x106.25Gbps (53.125GBd PAM4) optical interface, IEEE 802.3 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. 

     

    SiPh transceiver module integrate key photonics  and functionality components into the SiPh chip, meeting the harshest external operating conditions including temperature, humidity and EMI interference of the latest network architectures in data centers. The SiPh module provides high functionality and feature integration, accessible via a two-wire serial interface.

    Product details

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

    The 800G OSFP 2DR4 SiPh 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.

    Highly Integrated Low-power Interconnect Solution

    Silicon photonic modules achieve high integration, low cost, and low power consumption (reduced by nearly 40% compared to traditional solutions) through silicon-based optoelectronic integration technology. They support high-speed, long-distance transmission and are ideal for high-speed interconnects in AI and data centers.

     

    Highly Integrated Low-power Interconnect Solution

     

     

    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.
