Keep critical uplinks stable across longer fiber runs with the Cisco SFP-10/25G-LR-I. This SFP28 transceiver supports 10G and 25G Ethernet over single-mode fiber, giving infrastructure teams a clean path for high-speed aggregation, server access, and switch-to-switch connectivity where reach and signal integrity matter. The LC connector and LR optical profile are designed for disciplined deployment in enterprise networks that need predictable performance without overbuying capacity. For teams standardizing on 25 GbE, this module helps preserve headroom for growth while maintaining compatibility with 10 GbE environments during staged upgrades. Cisco optics are often selected where link consistency, platform alignment, and operational confidence outweigh the lowest upfront cost. This module fits that model: a purpose-built transceiver for production networks that need long-reach fiber connectivity and dependable day-to-day operation.
