Yiyuan 800G QSFP-DD SR8 850nm 100m MPO-16 Multimode Optical Transceiver
Yiyuan 800G QSFP-DD SR8 850nm 100m MPO-16 Multimode Optical Transceiver
Yiyuan 800G QSFP-DD SR8 Multimode Optical Transceiver | PAM4 | 850nm | 100m | Single MPO-16/APC | DOM
The Yiyuan 800G QSFP-DD SR8 optical transceiver delivers 800Gbps over up to 100 meters of OM4 multimode fiber using 8×100G PAM4 parallel channels. Engineered with a single MPO-16/APC optical interface and low-power VCSEL architecture (< 14W), it offers maximum port density and thermal reliability for next-generation AI GPU compute clusters (NVIDIA Spectrum-4, Arista 7060X5) and hyperscale spine-leaf fabrics.
Key Features
- 800Gbps in QSFP-DD 800: High-density form factor conforming to QSFP-DD MSA and CMIS 5.0.
- 100m Reach over OM4: Covers inter-rack and intra-rack high-speed links in AI clusters (60m over OM3).
- Low Power Consumption: Consumes < 14W (typical ~13.2W) to prevent switch chassis overheating.
- Single MPO-16/APC Interface: Simplifies fiber patch management and minimizes optical insertion loss.
- PAM4 8×100G Architecture: High-efficiency 850nm VCSEL transmitter array with low Bit Error Rate (BER).
- Digital Optical Monitoring (DOM): Real-time I2C telemetry for optical power, temperature, and voltage.
- Breakout Capable: Supports native 800GBASE-SR8 or breakout to 2x 400G SR4.

Frequently Asked Questions (FAQ)
Q1: Is the Yiyuan 800G QSFP-DD SR8 transceiver compatible with Arista and NVIDIA switches?
A: Yes. The YY-QSFPDD-SR8-100M is fully compliant with QSFP-DD MSA and CMIS 5.0 standards. Each module is pre-coded, verified, and EEPROM-matched for seamless plug-and-play operation with major data center switches, including Arista 7060X5/7800 series and NVIDIA Quantum-2 / Spectrum-4 platforms without triggering port errors.
Q2: What is the thermal and power performance under high-density AI cluster workloads?
A: The module is engineered with an optimized DSP architecture and high-efficiency VCSELs, maintaining power consumption strictly below 14W (typical ~13.2W). This low-power footprint prevents thermal throttling in high-density 800G switch chassis, ensuring stable long-term BER (Bit Error Rate) performance.
Q3: Does this 800G optical transceiver support breakout configurations?
A: Yes. Operating over an MPO-16 interface, the 800G QSFP-DD SR8 can operate in native 800GBASE-SR8 mode, or breakout into 2x 400G SR4 (via MPO-16 to 2x MPO-8 breakout cables) depending on your switch port configuration and NOS settings.
Q4: How can enterprise customers request validation samples?
A: Yiyuan Optical Link provides qualification samples for overseas system integrators, AI data center operators, and network labs. Contact us through our inquiry form with your target switch models and port configurations for tailored testing and fast dispatch.
