Ernitec ELECTRA-S-SFP-C mrežni transceiver modul, optički

The Ernitec ELECTRA-S-SFP-C is a compact SFP copper transceiver module compliant with the SFP Multi Source Agreement (MSA) and designed for Gigabit Ethernet 1000BASE-T networks. It provides a standard SFP interface in a metallic housing (approximately 15 mm x 60 mm x 10 mm) and supports SERDES operation. The module exposes the 1000BASE-T physical layer IC (PHY) via I2C for access to PHY settings and features. For correct operation, 1000BASE-X auto-negotiation should be disabled on the host system.

Advantages

The ELECTRA-S-SFP-C offers a compact form factor compatible with SFP slots, low weight and a metallic finish for durability. Direct I2C access to the PHY enables configuration and diagnostics of physical-layer settings. Compatibility with IEEE 802.3 Gigabit Ethernet ensures interoperability with standard network equipment when used with proper host configuration.

Suitable for

• Upgrading SFP-enabled switches and routers to support 1000BASE-T copper links
• Compact network installations where space and weight are constrained
• Environments requiring direct PHY access for configuration or diagnostics

Key specifications

• Interface type: SFP

• PHY access: I2C
• SERDES support: Yes
• Auto-negotiation note: Disable 1000BASE-X auto-negotiation on host
• Dimensions (approx.): 15 mm × 60 mm × 10 mm
• Weight: 0.018 kg
• Colour: Metallic

How to use

Insert the ELECTRA-S-SFP-C into a compatible SFP slot on the host device following the host manufacturer’s hot-plug procedure. Ensure the host network interface is configured for 1000BASE-T operation and that 1000BASE-X auto-negotiation is disabled if the host firmware or driver provides that setting. Use I2C access from the host or management controller to read or modify PHY settings when needed.

Recommendations

Use the transceiver in equipment that explicitly supports copper SFP modules and follow the host vendor guidance for SFP compatibility. Disable 1000BASE-X auto-negotiation on the host system and perform PHY configuration via I2C only if you understand the PHY parameters to avoid link issues.
