Refurb Squared NVIDIA/Mellanox Compatible 800GBASE 2 x LR4 OSFP Closed Finned Top 8 x 100G PAM4 1310nm 10km DOM Dual Duplex LC/UPC SMF Ethernet Optical Transceiver Module

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.

The 800GBASE 2x LR4 OSFP optical transceiver module is designed for 800GBASE Ethernet throughput up to 10km link lengths over OS2 single-mode fiber (SMF) via dual duplex LC/UPC connectors. This transceiver is compliant with IEEE 802.3ck, OSFP MSA and CMIS Rev 5.0 standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parameters. The twin-port OSFP closed finned top transceiver is used in Ethernet air-cooled switches. Featured with low latency, low power, and reliability, it can link upward in spine-leaf architectures for switch-to-switch applications, downward for top-of-rack switch links to Ethernet network adapters, and/or to BlueField-3 DPUs in compute servers and storage subsystems. It is the ideal solution for HPC computing, AI, and cloud data centers. Note: This "Closed Finned Top" refers to a closed top design, which uses a finned-top but with a lid on top of the fins creating a closed channel for additional cooling. It is engineered to support both airflow cooling and liquid-cooled environments, offering enhanced mechanical protection and thermal compatibility in high-density systems.

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.
