Product Highlights

• This transceiver is designed for 200G InfiniBand HDR (High Data Rate) applications, delivering 200Gbps line-rate transmission over single-mode fiber (SMF).
• It operates at 1310nm using the FR4 (4-lane CWDM) architecture, supporting a maximum reach of 2km over standard G.652 single-mode fiber.
• It is optimized for use in Mellanox HDR InfiniBand switches and adapters, ideal for short-to-medium range data center fabric links.

• It uses the industry-standard QSFP56 (200G Quad Small Form-factor Pluggable 56) package, which is compact, hot-swappable, and optimized for high-density HDR InfiniBand equipment.
• It is natively validated for use with Mellanox HDR switches (e.g., Quantum HDR platforms) and compatible adapters.
• The hot-pluggable design allows for easy installation, replacement, and capacity expansion without disrupting network operations.

• Built-in Digital Optical Monitoring (DOM) allows real-time monitoring of key parameters including TX/RX optical power, module temperature, supply voltage, and laser bias current.
• Certified as a Class 1 Laser product under 21CFR1040.10 standards, meeting strict data center safety and performance requirements.
• Manufactured in China, it undergoes rigorous factory testing to ensure stable performance in the commercial temperature range (0°C to 70°C).
