Arista QDD-800G-2FR4 Compatible 800GBASE-2FR4 Twin-port QSFP-DD PAM4 1270 to 1330nm 2km DDM Dual Duplex LC/UPC SMF Optical Transceiver Module

We evaluated several 800G transceivers before making a purchase and ultimately selected this one based on the available documentation and technical specifications. The module arrived in excellent condition, installation was uncomplicated, and the optical link performed consistently throughout our verification process. Overall, the buying experience and product quality met our expectations.

One thing I liked was that there were no surprises. The specifications matched the product we received, the module was cleanly manufactured, and our validation tests were completed without any unexpected issues. That's all we really ask for when sourcing optics.

Our purchasing team was mainly focused on reducing the overall networking budget. These modules helped us achieve that without sacrificing reliability. After installation, they performed just as well as some higher-priced alternatives we've used previously.

The labeling on the module is clear and easy to read, including the model and interface information. It saved us from double-checking each transceiver during installation, especially when working with different module types in the same rack.

What impressed me most was the delivery speed. The modules arrived earlier than expected, which helped us stay on schedule for a network upgrade.

We chose this 800G 2FR4 QSFP-DD module mainly for its long-reach capability, and it has proven very effective in 2km SMF links. The dual-port design offers flexible network layout options.

Their inventory availability was much better than other suppliers we checked. We were able to get what we needed without a long wait.

What stood out was the value for the money. Comparable options were noticeably more expensive, but these fit our budget without cutting corners.

All good, thanks for your attention.

Compared with original manufacturer modules, these optical transceivers offer excellent value for the price. They deliver reliable performance while helping us reduce network upgrade costs without compromising quality.
