Refurb Squared Arista Compatible QDD-800G-2xDR4 1310nm 500m Dual MTP/MPO-12 APC SMF Finned Top Optical Transceiver Module for 7060DX5-64E Switch

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 Arista compatible QDD-800G-2xDR4 optical module is designed for 800G Ethernet optical interconnects based on PAM4 modulation, integrating two independent 400G DR4 channels within a QSFP-DD form factor. Compliant with the QSFP-DD MSA and IEEE 802.3ck / 802.3cu standards, the module delivers an aggregate data rate of 800Gb/s, with each 400G channel implemented as a 4×100G PAM4 parallel interface. Designed for Arista 7060DX5-64E switch, the module ensures stable high-speed signal transmission and consistent performance in high-bandwidth environments. By using MPO-12 APC connectors, each DR4 channel supports 4-lane 100G transmission, enabling flexible connectivity between 800G QSFP-DD ports and either native 800G modules or breakout configurations to two 400G DR4 QSFP-DD modules. This makes the QDD-800G-2xDR4 well suited for high-density 800G switching systems that require scalable bandwidth deployment and smooth migration between 400G and 800G Ethernet architectures.

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.
