Teltonika PR4JR20K SFP Transceiver — 1.25Gbps Copper

The Teltonika PR4JR20K is a professional-grade 1.25 Gbps Copper RJ45 SFP transceiver designed to extend fiber connectivity to copper infrastructure. This versatile network component enables seamless integration between fiber-based switching equipment and traditional Ethernet copper cabling, making it an essential accessory for deployments requiring flexible connectivity options. At a current price of $57.50 inc GST (reduced from $107.80), this transceiver represents excellent value for installations where converting SFP ports to standard RJ45 Gigabit Ethernet connections is needed.

• 1.25 Gbps throughput ensures full Gigabit Ethernet performance without bottlenecks
• RJ45 copper interface allows standard Cat5e/Cat6 cable connections up to 100 meters
• Hot-swappable design enables installation and replacement without network downtime
• Universal SFP compatibility works with UniFi switches and other managed networking equipment with SFP ports

This transceiver is particularly valuable for network administrators who need to connect fiber-capable switches to existing copper infrastructure, or who require the flexibility to use standard Ethernet cables for shorter runs while reserving fiber for longer distances. The Teltonika PR4JR20K provides a cost-effective solution for mixed-media networks, eliminating the need for dedicated media converters and simplifying network architecture in small business and professional installations where reliable, high-performance connectivity is essential.
