Arista QDD-800G-SR8 – QSFP-DD SR8 Optical Transceiver

About Arista QDD-800G-SR8 QSFP-DD SR8 Optical Transceiver in Bangladesh

The Arista QDD-800G-SR8 is an 800Gbps QSFP-DD SR8 optical transceiver designed for high-density data center, AI, cloud, and high-performance computing networking. Using eight parallel optical lanes with 100G PAM4 signaling per lane, it provides an aggregate optical bandwidth of 800Gbps over compatible multimode fiber.

The QDD-800G-SR8 operates at an 850nm-class optical wavelength and uses a parallel MPO-16 optical interface. Its short-reach multimode architecture is designed for high-bandwidth connections within data centers, including switch-to-switch, rack-to-rack, leaf-spine, and AI cluster networking applications.

With compatible multimode fiber, SR8 optics are intended for short-distance 800GbE links. The exact supported reach depends on the module implementation and fiber grade; commonly specified deployments support up to approximately 60 meters over OM3 and 100 meters over OM4 fiber.

Arista QDD-800G-SR8 QSFP-DD SR8 Optical Transceiver Specifications & Overview

Overview

The Arista-compatible QDD-800G-SR8 provides 800Gbps optical Ethernet connectivity through a high-density QSFP-DD interface. It is designed for modern data center networks where extremely high bandwidth and efficient front-panel port density are required.

The SR8 architecture uses eight parallel optical lanes, with each lane carrying 100Gbps using PAM4 modulation. Together, the eight lanes provide an aggregate 800Gbps optical connection while maintaining a compact pluggable form factor.

The 850nm multimode optical architecture is optimized for short-reach data center applications. With suitable OM4 multimode fiber, SR8 implementations can support links of up to approximately 100 meters, making the module suitable for rack-to-rack and short data center fabric connections.

The MPO-16 APC interface provides eight optical transmit/receive lane pairs. Correct connector type, fiber polarity, lane mapping, and multimode fiber grade must be verified before deployment.

Frequently Asked Questions (FAQ)

Q1: What is the data rate of the QDD-800G-SR8?
The QDD-800G-SR8 is designed for 800Gbps Ethernet connectivity using eight parallel optical lanes.

Q2: What does SR8 mean?
SR8 refers to a short-reach parallel optical architecture using eight optical lanes. In an 800G implementation, each lane carries approximately 100Gbps using PAM4 modulation.

Q3: What form factor does the QDD-800G-SR8 use?
It uses the QSFP-DD800 form factor, designed to provide very high bandwidth while maintaining high network port density.

Q4: What type of fiber does the 800G SR8 use?
The SR8 architecture is designed for parallel multimode fiber (MMF).

Q5: What wavelength does the QDD-800G-SR8 use?
The transceiver uses an 850nm-class optical wavelength.

Q6: What is the reach of the QDD-800G-SR8?
The exact reach depends on the module and fiber implementation. Common specifications support approximately 60 meters over OM3 and up to 100 meters over OM4 multimode fiber.

Q7: What connector does the QDD-800G-SR8 use?
The SR8 architecture uses an MPO-16 APC parallel-fiber interface.

Q8: Is the QDD-800G-SR8 suitable for AI networking?
Yes. Its 800Gbps bandwidth and high-density QSFP-DD architecture make it suitable for AI clusters, GPU fabrics, HPC environments, and high-throughput data center networks.

Q9: What is the difference between 800G SR8 and 800G DR8?
800G SR8 is designed for short-reach multimode fiber, while 800G DR8 is designed for longer links over parallel single-mode fiber. SR8 is therefore generally used for shorter in-rack or intra-data-center connections.

Q10: Is every QSFP-DD800 port compatible with the QDD-800G-SR8?
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-SR8 an official Arista part number?
Arista's current public 800G documentation does not list QDD-800G-SR8 among its current 800G QSFP-DD models. Third-party sources list QDD-800G-SR8 as an Arista-compatible module, so the exact manufacturer and coding should be confirmed before ordering.

Q12: Where can I buy the QDD-800G-SR8 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.
