Product Overview
The SFP-25G-SR-S is a high-performance 25G SFP28 optical transceiver designed for short-range data transmission over multimode fiber (MMF). It supports 25 Gigabit Ethernet connections with a maximum reach of 70 meters on OM3 fiber and up to 100 meters on OM4 fiber. This transceiver is ideal for high-density data centers, cloud networks, and enterprise environments requiring fast, reliable short-distance connectivity. It fully complies with IEEE 802.3by 25GBASE-SR standards.
Product Details
Operating at a wavelength of 850 nm, the SFP-25G-SR-S delivers 25 Gbps data rates through an LC duplex interface. It features low power consumption and Digital Diagnostics Monitoring (DDM), providing real-time information on temperature, voltage, and optical performance. This hot-swappable module is backward compatible with 10G speeds (when supported by host devices), making it a flexible and cost-effective solution for modern high-speed network infrastructures.
