Arista QDD-8X25-MR-SR-E | 200G QSFP-DD Transceiver, Dual-Rate 8x25G/8x10G, MMF

Q: What is the difference between E-Series and standard Arista transceivers?
A: E-Series transceivers are enhanced performance optics designed for ultra-low latency applications. They eliminate Forward Error Correction (FEC) requirements, saving up to 250ns of latency, making them ideal for high-frequency trading, HPC, and latency-sensitive workloads.

Q: Can this transceiver operate at both 25G and 10G speeds?
A: Yes, the QDD-8X25-MR-SR-E is dual-rate and can operate at 8x25G-SR (200G total) or 8x10G-SR (80G total). It can also support 2x100G-4 breakout configurations, providing flexible deployment options for various network architectures.

Q: Which Arista platforms support this transceiver?
A: This transceiver is supported on all Arista QSFP-DD ports, including ultra-low latency 7130B Series switches, and QSFP-DD ports on 7050X and 7060X platforms running EOS 4.31.1 or later.

Q: What type of fiber cable is required?
A: The QDD-8X25-MR-SR-E requires OM3 or OM4 multimode fiber with an MPO-16 APC connector. For optimal performance and maximum distance (100m), OM4 fiber is recommended.

Q: Is this transceiver suitable for optical breakout applications?
A: Yes, this E-Series transceiver supports optical breakout configurations, allowing you to split the 8 lanes into multiple lower-speed connections for flexible network design and connectivity options.
