Refurb Squared NVIDIA/Mellanox MMS4A50-XM-RHS (980-9IAS1-00XM00) Compatible 1.6T 2xFR4 OSFP224 RHS/Flat Top PAM4 Broadcom 3nm DSP (Sian3 | BCM83628) 1310nm 2km SMF DOM Dual LC Duplex InfiniBand XDR Silicon Photonics 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.

RS NVIDIA/Mellanox compatible OSFP-1.6T-2FR4FH is a 1.6Tb/s twin-port OSFP optical transceiver, delivering 2x800Gb/s links over single-mode fiber (SMF) within up to 2km. It is designed for next-generation 1.6T data center networks and InfiniBand fabrics. The 1.6T OSFP 2xFR4 module adopts a dual FR4 architecture (2xFR4), providing 8 optical channels in total, with each port carrying 4x200G-PAM4 lanes. Optical signals are transmitted using CWDM4 serial multiplexing on the 1310nm wavelength grid, enabling efficient high-density, long-reach transmission. For physical connectivity, the transceiver uses two LC duplex connectors, each operating over two single-mode fibers, supporting far-reach FR4 links while maintaining compact port density in OSFP form factors. The connector housing features a RHS/flat top design, enhancing thermal dissipation and ensuring optimal space compatibility in high-density switch deployments. The OSFP-1.6T-2FR4FH integrates Silicon Photonics chips and the Broadcom 3nm Sian3 (BCM83628) DSP to deliver 1.6Tb/s optical performance with high signal integrity and energy efficiency. Designed for liquid-cooled 1.6T switch-to-switch interconnects, it supports scalable deployment of next-generation InfiniBand fabrics in AI and HPC data centers.

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.
