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 Juniper compatible QDD-800G-2xDR4 is a high-speed optical module based on PAM4 modulation, delivering an aggregate transmission capacity of 800Gb/s by integrating two independent 400G DR4 channels. Compliant with the QSFP-DD MSA and IEEE 802.3ck / 802.3cu standards, each 400G channel is implemented as a 4×100G PAM4 parallel interface, enabling high-bandwidth, lane-based optical interconnects for next-generation Ethernet systems. And it is compatible with Juniper QFX5240 Series switch, enabling standardized 800G QSFP-DD optical connectivity. Using an MPO-12 interface per channel, the module supports flexible connectivity on switches equipped with 800G QSFP-DD ports. Through MPO-12 APC fiber cables, it can be deployed either as a native 800G optical link or in a breakout configuration connecting to two 400G DR4 QSFP-DD modules, making it suitable for scalable 800G switching.

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.
