Product Advantages
Intel LTF8505-BC-IN is optimized for Intel Ethernet environments and provides stable 25GbE high-speed connectivity for enterprise and hyperscale data center deployments. It uses an 850nm VCSEL laser and supports multimode fiber infrastructure, making it cost-effective for short-distance high-bandwidth networking.
The module supports both 10G and 25G transmission rates, allowing flexible migration from 10GbE to 25GbE networks without replacing existing multimode cabling infrastructure.
With low power consumption of approximately 0.3W, the module reduces heat generation and improves switch port density efficiency in large-scale data centers.
It supports DOM/DDM digital diagnostics, enabling administrators to monitor temperature, voltage, TX optical power, and RX optical power in real time for easier maintenance and troubleshooting.
The hot-swappable SFP28 form factor allows replacement without shutting down equipment, improving maintenance efficiency and minimizing downtime in enterprise networks.
Intel-coded EEPROM programming ensures strong compatibility with Intel XXV710 and E810 network adapters, helping avoid compatibility alarms and link negotiation issues commonly found with generic optics.
