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 MMS4X00-NM- FLT compatible OSFP-800G-2xDR4F optical transceiver is designed for 800Gb/s Ethernet interconnects, using a twin-port OSFP architecture to support 2×400Gb/s DR4/DR8 single-mode transmission over an 8-channel parallel optical interface. The module operates via two MPO-12/APC connectors, with each connector carrying four optical lanes, and applies 100G-PAM4 modulation to enable data centerœreach links of up to 500 meters over single-mode fiber. The module is compatible with NVIDIA ConnectX-8 C8180 SuperNIC, delivering stable, high-speed optical connectivity. By adopting a parallel DR4/DR8 design optimized for short-to-medium reach connectivity, the OSFP-800G-2xDR4F enables high port density and efficient bandwidth scaling in 800G switching systems. Finned-top OSFP shells are supported to meet the additional cooling requirements of 800G OSFP switches, while a flat-top variant is available for ConnectX-8 system links, providing flexibility across different deployment platforms.

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.
