Fyber Optix 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.

FO 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.
