Description

The Arista QDD-800G-2XDR4 is an 800G QSFP-DD optical transceiver designed for high-density data centre switching environments, supporting 8x 100GBASE-FR or 2x 400G-XDR4 operation over parallel single-mode fibre. Featuring dual MPO-12 APC connectors, it delivers native 800G-to-2x400G breakout connectivity at distances up to 2km — eliminating the need for external optical breakout cables and simplifying cabling infrastructure significantly.

Operating across 8x 106.25 Gb/s PAM-4 lanes at 1310nm, this transceiver is fully compliant with IEEE 802.3cu and QSFP-DD MSA standards, and interoperates with 2x 400G-XDR4 OSFP/QSFP-DD and 8x 100G-FR QSFP devices. Digital Diagnostic Monitoring (DDM/DOM) provides real-time visibility into optical performance parameters. Upgrade your network with gear from iptrading.com.au — Australia's IT hardware specialists.

Features

- Supports 8x 100GBASE-FR or 2x 400G-XDR4 breakout operation for flexible bandwidth allocation
- Dual MPO-12 APC connectors provide two physically independent 400G XDR4 links — no breakout fibre cables required
- 8x 106.25 Gb/s PAM-4 transmit and receive lanes for full 800G aggregate throughput
- Digital Diagnostic Monitoring (DDM/DOM) for real-time optical parameter visibility
- Hot-pluggable QSFP-DD form factor for non-disruptive installation in live environments
- Interoperable with 2x 400G-XDR4 OSFP/QSFP-DD and 8x 100G-FR QSFP devices
- IEEE 802.3cu and QSFP-DD MSA compliant for broad ecosystem compatibility
- RoHS compliant for regulatory and environmental compliance
- Optimised for high-density 800G Ethernet switching and spine-leaf data centre architectures

FAQs

Q: What modes of operation does the QDD-800G-2XDR4 support?
A: The QDD-800G-2XDR4 supports two modes: 8x 100GBASE-FR operation (eight independent 100G lanes) or 2x 400G-XDR4 operation, providing 800G aggregate throughput in a single QSFP-DD module.

Q: Does this transceiver require optical breakout cables?
A: No. The dual MPO-12 APC connectors allow it to natively establish two separate 400G XDR4 links, eliminating the need for external optical breakout cables and simplifying data centre cabling.

Q: What is the maximum transmission distance?
A: The QDD-800G-2XDR4 supports reach up to 2km over parallel single-mode fibre (SMF), making it suitable for intra-campus and long-reach data centre interconnects.

Q: Which devices is the QDD-800G-2XDR4 compatible with?
A: It is interoperable with 2x 400G-XDR4 OSFP and QSFP-DD devices as well as 8x 100G-FR QSFP transceivers. It complies with IEEE 802.3cu and QSFP-DD MSA standards for broad cross-vendor compatibility.

Q: What monitoring capabilities does this transceiver provide?
A: The transceiver supports Digital Diagnostic Monitoring (DDM/DOM), enabling real-time visibility into optical parameters such as transmit/receive power, temperature, and supply voltage.

Q: Can I purchase the Arista QDD-800G-2XDR4 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware specialist supplying Arista transceivers and networking optics to enterprise and data centre customers across Australia. Contact us for pricing, availability, and volume enquiries.
