2.5GBASE-T Copper SFP Transceiver: 2.5G-SFP-T

Our EDGEOPTIC 2.5G-SFP-T is a multi-vendor compatible 2.5GBASE-T copper SFP module designed to enable SFP-equipped networking devices to achieve enhanced bandwidth over standard copper twisted pair cabling. This copper transceiver provides a cost-effective solution for upgrading network performance beyond Gigabit speeds without requiring fiber optic infrastructure deployment, making it ideal for environments seeking bandwidth improvements while leveraging existing copper cabling investments.

The 2.5G-SFP-T module supports multi-rate operation across 2.5GBASE-T, 1000BASE-T, and 100BASE-T Ethernet standards, providing flexible speed operation from 100 Mbps to 2.5 Gbps with auto-negotiation capability. This multi-rate functionality enables seamless integration with mixed-speed environments while delivering 2.5 Gigabit performance where endpoints support it. The module features an integrated RJ45 connector providing direct copper connectivity without requiring external media converters. Transmission distances reach up to 80 meters over Category 5e, 6a, or 7 twisted pair cabling, with actual distance dependent on cable quality and installation conditions. The LOS (Loss of Signal) function is enabled, providing reliable link status indication for network management systems.

The 2.5G-SFP-T is a hot-pluggable SFP module featuring an RJ45 electrical interface. The host-side electrical interface conforms to INF-8074i and SFP MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems across multiple vendor equipment platforms. Our copper SFP transceiver can be encoded for compatibility with 80+ equipment brands, enabling seamless integration into existing network infrastructure. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality where supported by the host equipment, providing real-time operational parameters for comprehensive monitoring of transceiver health and performance.

The SFP form factor, while considered a legacy standard, remains widely deployed across enterprise, carrier, and industrial networks due to its proven reliability and broad equipment support. The 2.5GBASE-T standard, defined in IEEE 802.3bz (NBASE-T and MGBASE-T), addresses the growing need for bandwidth beyond Gigabit Ethernet while utilizing existing Cat5e and Cat6 cabling infrastructure. This makes the 2.5G copper SFP particularly valuable for enterprise environments where replacing copper cabling with fiber would be cost-prohibitive, yet applications like wireless access point backhaul, NAS connectivity, and workstation upgrades demand bandwidth exceeding 1 Gbps. The module operates within a standard 0°C to 70°C commercial temperature range, suitable for typical data center and enterprise equipment room environments. Power requirements are met by a single +3.3V supply, though 2.5G copper SFP modules typically consume more power than Gigabit variants due to enhanced PHY circuitry requirements.

Standards compliance includes IEEE 802.3bz for NBASE-T and MGBASE-T operation at 2.5 Gbps. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for full compatibility. Our copper SFP transceiver is CE and RoHS certified.

Typical applications include wireless access point backhaul requiring bandwidth beyond Gigabit, NAS and storage device connectivity, desktop workstation upgrades, edge computing deployments, and any environment seeking cost-effective bandwidth improvements over existing copper infrastructure. The 2.5G copper SFP module enables network upgrades without fiber deployment when endpoints support 2.5GBASE-T operation. Because our focus is providing top quality service, we perform rigorous quality checks before delivery. This includes electrical parameter testing, connector inspection, and SFP transceiver EEPROM memory data validation tests.
