SFP28 Optical Transceiver

The T1Nexus 25G SFP28 (Small Form-factor Pluggable 28) Optical Transceiver Series delivers high-density, low-latency 25Gbps connectivity engineered for modern data center server access, enterprise switch uplinks, 5G wireless fronthaul networks, and high-frequency trading (HFT) environments.

Offering a direct 2.5x speed upgrade over legacy 10G SFP+ interfaces within the exact same physical footprint, T1Nexus SFP28 modules support NRZ modulation with optimized low power consumption (typically under 1.0W to 1.5W per port). Distributed in the UK and Ireland by Frame, each module is custom-coded in-house for complete hardware interoperability and real-time DOM/DDM telemetry reporting.

Key Product Features

• High-Speed 25G NRZ Performance: Compliant with SFF-8402, SFF-8472, IEEE 802.3by 25GBASE, and IEEE 802.3cc standards.
• Low Power & Ultra-Low Latency: Optimized transmitter optics keep power draw under 1.0W–1.8W, reducing cooling overhead in high-density rack deployments.
• Backward Compatibility: Seamlessly operates at 10Gbps speeds (10GBASE-SR/LR) on dual-rate ports to support phased infrastructure migrations.
• Broad Media Options: Available in SR (multimode), eSR, LR, ER, Single-Strand BiDi (Bidirectional), CWDM, and DWDM configurations.
• Precoded: Pre-programmed in the UK for native hardware identification across Cisco, Arista, Juniper, Dell, HPE/Aruba, Extreme, and Edgecore platforms.
• UK-Based Stock & Support: Dispatched directly from Frame's UK warehouse with direct technical support and a 5-year advance-replacement warranty.
