400G QSFP-DD FR4 PAM4 1310nm 2km DOM LC Duplex Single-Mode Optical Module

400G QSFP-DD FR4 Single-Mode Optical Module | PAM4 | 1310nm | 2km | DOM | LC Duplex

The Yiyuan Guanglian 400G QSFP-DD FR4 optical module is engineered for medium-reach single-mode fiber transmission in hyperscale data centers and campus network interconnects. Utilizing PAM4 modulation with 4×100G WDM channel architecture, it supports a maximum transmission distance of 2 kilometers over SMF — the ideal choice for inter-building and inter-data-center links.

Key Features

• High Bandwidth: 400Gbps aggregate bandwidth, ideal for data center interconnect and spine-leaf architectures
• PAM4 WDM Modulation: 4×100G PAM4 over four wavelengths (1310nm band) for efficient single-mode fiber utilization
• Digital Optical Monitoring (DOM): Real-time monitoring of temperature, voltage, bias current, and TX/RX optical power for simplified operations and maintenance
• 1310nm Wavelength: Low-dispersion transmission window, optimized for medium-reach single-mode links
