Overview — The Perfect Fit Where More Network Throughput is Key
Fast, low-cost, future-proof way to deploy long network segments. SFP ports allow for the use of fibre-optic connections, expanding the Ethernet network beyond 100m, ensuring reliable data transmission over long distances without signal degradation, and maintaining data integrity and system stability.
Network resilience and security. Fibre-optic connections are less susceptible to electromagnetic interference and electrical noise, reducing the risk of communication disruptions, and ensuring continuous data exchange between components, even in the most remote locations and challenging environmental conditions.
SFP scalability and expansion. The switches' modular design and support for SFP transceivers make it straightforward to add new devices or upgrade existing ones without major changes to infrastructure.
