    Specifications

    NVIDIA/Mellanox Compatible 800GBASE-LR8 (2xLR4) OSFP IHS/Closed Finned Top PAM4 InfiniBand NDR Optical Transceiver Module (1310nm, 10km, 2x MPO-12/APC Connectors, SMF, 0℃ to +70℃, DDM)

     

    NVIDIA/Mellanox compatible 800G LR8 OSFP is an InfiniBand NDR and Ethernet optical transceiver module with dual MPO-12/APC connectors. It enables the fiber link of 10km at 850Gb/s over MTP/MPO single-mode fiber (SMF). With the Pulse-amplitude Modulation (PAM4) modulation, the long reach 8-channel (LR8) OSFP adopts 8-channels of 100G-PAM4 electrical to dual 4x 100G-PAM4 optical parallel modulation.

     

    With a closed finned top design, the OSFP-IHS is offered for InfiniBand Quantum-2 or Ethernet Spectrum-4 air-cooled switches. Its main application is to link two switches together up to 10km meters. QSFPTEK NVIDIA Ethernet compatible optics are 100% tested in NVIDIA InfiniBand and Ethernet host devices, ideal for NVIDIA end-to-end InfiniBand NDR or Ethernet systems.

      Our network is expected to continue growing over the next few years, so we wanted a solution that wouldn't need to be replaced anytime soon. This LR8 module gives us enough reach and bandwidth to support future expansion without changing the existing fiber layout.

      Purchased this module for a longer-distance single-mode link. It connected quickly, delivered stable transmission, and DOM values have remained consistent over time. So far, it's been working exactly as expected.

      The LR8 design worked well for our inter-building fiber links. Since our existing infrastructure already used LC cabling, we were able to deploy the modules without replacing any patch cords, making the upgrade both faster and more cost-effective.

      This LR8 module was used for a longer-distance 800G link. Compared with shorter-reach optics we tested before. The optical performance has been consistent, and it has been running reliably since installation.

      Selected this LR8 module for a project that required longer fiber runs between network segments. The LC interface made installation convenient since it matched our existing cabling infrastructure. Being able to achieve 800G connectivity without redesigning the fiber plant was a major advantage for this deployment.

      Needed a long-reach 800G solution between two buildings on campus and decided to try this LR8 module. Optical power levels were healthy, and performance has been rock solid since deployment. I'm very satisfied with the result.
