Arista QDD-800G-DR8 – QSFP-DD DR8 Optical Transceiver

About Arista QDD-800G-DR8 QSFP-DD DR8 Optical Transceiver in Bangladesh

The Arista QDD-800G-DR8 is an 800Gbps-class QSFP-DD optical transceiver designed for high-density data center, AI, cloud, and high-performance computing networks. Using eight parallel 100G PAM4 optical lanes, it provides an aggregate 800Gbps optical connection over single-mode fiber.

The QDD-800G-DR8 operates around the 1310nm optical wavelength and uses an MPO-16 APC parallel-fiber connector. Its 8-lane DR8 architecture is designed for short-to-medium reach single-mode fiber connectivity, with published module specifications supporting distances of up to approximately 500 meters.

The module is suitable for high-bandwidth connections between switches, routers, AI clusters, GPU infrastructure, and other high-performance networking platforms. It can also support breakout applications where an 800G host interface is connected to multiple lower-speed optical interfaces, subject to host-platform and transceiver compatibility.

Arista QDD-800G-DR8 QSFP-DD DR8 Optical Transceiver Specifications & Overview

Overview

The Arista-compatible QDD-800G-DR8 provides ultra-high-speed 800Gbps optical connectivity through a high-density QSFP-DD800 interface. It is designed for modern data center and AI networking environments where bandwidth, port density, and scalable optical connectivity are critical.

The DR8 architecture uses eight parallel optical lanes, with each lane operating at approximately 100Gbps using PAM4 modulation. The eight lanes are combined to provide an aggregate 800Gbps optical connection.

Unlike 800G SR8 optics, which use multimode fiber for shorter distances, DR8 is designed for single-mode fiber and provides a longer reach of up to approximately 500 meters under suitable conditions. This makes it suitable for broader intra-data-center deployments and connections between network racks or zones.

The module uses an MPO-16 APC optical interface. Correct APC connector type, fiber polarity, lane mapping, and compatible single-mode fiber must be verified before installation.

Frequently Asked Questions (FAQ)

Q1: What is the data rate of the QDD-800G-DR8?
The QDD-800G-DR8 is designed for 800Gbps Ethernet connectivity using eight parallel optical lanes.

Q2: What does DR8 mean?
DR8 refers to a 8-lane data-center-reach optical architecture. The 800G implementation uses eight approximately 100Gbps PAM4 optical lanes.

Q3: What form factor does the QDD-800G-DR8 use?
It uses the QSFP-DD800 form factor, providing high bandwidth and high port density for modern data center switches.

Q4: What type of fiber does the QDD-800G-DR8 use?
The DR8 architecture is designed for single-mode fiber (SMF).

Q5: What wavelength does the QDD-800G-DR8 use?
The transceiver operates in the 1310nm-class optical band.

Q6: What is the reach of the QDD-800G-DR8?
Published module specifications indicate up to approximately 500 meters over suitable single-mode fiber. Actual reach depends on the optical budget, fiber plant, connectors, polarity, and host equipment.

Q7: What connector does the QDD-800G-DR8 use?
The module uses an MPO-16 APC parallel-fiber optical connector.

Q8: Can the QDD-800G-DR8 support breakout connectivity?
Published specifications for compatible QDD-800G-DR8 modules indicate support for 800G to 2 × 400GBASE-DR4 and 8 × 100G-DR breakout applications where the host platform and software support the required configuration.

Q9: What is the difference between 800G SR8 and 800G DR8?
800G SR8 is designed for short-reach multimode fiber, typically using 850nm-class optics. 800G DR8 uses 1310nm-class optics over single-mode fiber and provides substantially longer reach, making it more suitable for broader data center deployments.

Q10: Is every QSFP-DD800 port compatible with the QDD-800G-DR8?
No. The host platform must support the required 800GbE optical module, electrical interface, power and thermal requirements, firmware, and transceiver coding. Always verify compatibility before deployment.

Q11: Is QDD-800G-DR8 an official current Arista SKU?
Arista's current public documentation lists several 800G QSFP-DD options but does not currently list QDD-800G-DR8 in its main transceiver guide. Third-party optics vendors identify QDD-800G-DR8 as an Arista-compatible module, so the exact manufacturer and coding should be confirmed before ordering.

Q12: Where can I buy the QDD-800G-DR8 in Bangladesh?
You can contact Datacom Technologies (BD) for 800G QSFP-DD optical transceivers and Arista-compatible networking optics with competitive pricing, technical consultation, and nationwide delivery.
