Refurb Squared NVIDIA/Mellanox Compatible Coherent VCSEL & Broadcom DSP 800G OSFP 2xSR4/SR8 850nm 100m PAM4 DOM Two MPO-12/APC MMF Transceiver Module (Flat Top) for ConnectX-8 C8180 SuperNIC

Description

Refurb Squared delivers fully tested, OEM-compatible optical transceivers, DWDM/CWDM systems, media converters and DAC/AOC cables — coded for Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet platforms, with lifetime warranty and fast global delivery.

RS NVIDIA/Mellanox compatible OSFP-800G-2SR4F is an Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xSR4/SR8 multimode, parallel, 8-channel transceiver using two 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel 8-channel design adopts 100G-PAM4 modulation and supports up to 100 m transmission over 8 multimode fibers. Built-in Coherent VCSEL & Broadcom DSP, it is compatible with NVIDIA ConnectX-8 C8180 SuperNIC, ensuring stable signal integrity and high-speed 800G optical performance. Finned-top OSFP shells provide enhanced thermal dissipation for 800G switches, while flat-top versions are available for ConnectX-8 system links. The Twin-port 2xSR4/SR8 architecture enables efficient 2×400G breakout from a single 800G port, improving port density and deployment flexibility. It is well suited for high-bandwidth, low-latency optical fabrics in AI and HPC clusters, delivering scalable 800G connectivity with optimized power efficiency and reliable performance in high-density environments.

Refurb Squared is brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM/CWDM systems, media converters, and DAC/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet — backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.
