Description

Data General DG-25G-LR-SM1310

The SPT-SFP28-LR 25G SFP28 Optical Transceiver is an ultra-efficient, high-speed networking solution that supports up to 10km transmission over single-mode fiber (SMF). Designed for long-distance interconnects, this module is fully compliant with IEEE 802.3CC, SFF-8431, and SFF-8472 standards, making it an ideal choice for modern networking infrastructures.

Built with a DFB laser transmitter and PIN receiver, the SPT-SFP28-LR delivers exceptional signal integrity, ensuring low latency and high-reliability performance. The hot-pluggable SFP28 module supports digital diagnostic monitoring (DDM), providing real-time system monitoring for optical power, voltage, and temperature stability.

With low power dissipation (<1.2W), advanced firmware supporting encryption storage, and an all-metal EMI shielding design, the SPT-SFP28-LR offers superior network performance while reducing power consumption in high-density environments.
