Extralink SFP+ 10G SFP+ WDM Module 10Gbps 1270/1330nm single mode 20km LC DOM pair dedicated for HP/ARUBA

Extralink SFP+ 10G WDM module pair for HP/ARUBA provides a cost-effective solution for duplex 10 Gbps links over a single single-mode fibre using WDM wavelengths 1270 nm and 1330 nm. Each SFP+ transceiver supports up to 10 Gbit/s and a maximum reach of 20 km with LC connectors. The modules include a two-wire I2C serial interface and support digital optical monitoring (DOM) for real‑time access to parameters such as received optical power, laser bias current and transmit power. The electrical interface meets SFI electrical specifications and the receiver outputs PECL/CML serial electrical data, making the modules suitable for use in 10 Gbps Ethernet, SONET/SDH and various 10 Gbps optical channel applications on compatible HP/ARUBA equipment.

Advantages

The Extralink SFP+ WDM pair is designed for compatibility with HP/ARUBA devices and offers DOM-enabled diagnostics, a compact LC single-mode form factor and support for 10 Gbit/s links up to 20 km. The two-wire I2C interface provides module identification and control while the SFI-compliant electrical interface ensures interoperability with standard 10G line cards and switches.

Suitable for

• 10 Gbps Ethernet uplinks and inter-switch connections
• SONET/SDH and telecom optical links
• High-speed links between HP/ARUBA routers and switches
• Longer-distance single-mode fibre runs up to 20 km

Key specifications

• Form factor: SFP+
• Wavelengths (pair): 1270 nm (Tx or Rx) and 1330 nm (Tx or Rx) for bidirectional WDM
• Maximum data rate: up to 10 Gbit/s
• Maximum reach: 20 km (single-mode fiber)
• Connector: LC
• Digital Optical Monitoring (DOM): supported via I2C
• Compatibility: dedicated for HP/ARUBA devices

How to use

Insert each SFP+ transceiver into the appropriate SFP+ slot on HP/ARUBA equipment, ensuring the correct orientation and secure seating. Connect a single-mode LC patch cord between the two modules; the pair uses WDM so each module transmits and receives on different wavelengths over a single fiber. Ensure network ports are configured for 10 Gbps operation and check system logs or DOM registers via the host device to verify link status and optical parameters.

Recommendations

Use certified single-mode LC patch cords and verify compatibility with your HP/ARUBA device firmware. Monitor DOM values after installation to confirm proper optical power levels and to detect potential issues such as excessive attenuation or faulty connectors.
