Key Product Parameters of 800G DR8 Transceiver

Q1:  800G DR8 VS 800G FR4, What is the primary difference ? A1: The primary differences are fiber type layout and distance. DR8 uses parallel optics (8 lanes of 100G running over 8 pairs of single-mode fiber) and reaches up to 500 meters. It is ideal for short-reach high-density environments and allows 8x100G or 2x400G breakouts. FR4 uses coarse wavelength division multiplexing (CWDM) over a single duplex LC fiber pair to reach up to 2km, but it does not natively breakout into 8 individual 100G lines.

Q2: Can the Arista QDD-800G-DR8 operate in breakout mode? A: Yes. This 800G DR8 module natively supports breakout applications. Using appropriate MPO breakout F/F cables, it can be configured in Arista EOS to split into 2x 400G (DR4) or 8x 100G (DR) channels.

Q3: What type of fiber cable and connector are required for this transceiver? A3: The  Arista-compatible 800G DR8 module requires an MPO-16 (APC) connector operating over Single-Mode Fiber (SMF/OS2). Ensure you use an APC (Angled Physical Contact) connector to prevent back-reflection and protect the optical components. 

Q4: Is this module hot-swappable, and does it support DOM? A4: Yes, it is fully hot-pluggable, meaning it can be installed or removed without powering down the switch. It also features built-in Digital Optical Monitoring (DOM/DDM), allowing network administrators to monitor real-time metrics like TX/RX optical power, temperature, and voltage via the Arista CLI.
