## Summary description

Extralink SFP WDM pair (2 pcs) is a fiber optic SFP transceiver set for single‑mode links with 1310/1550 nm wavelengths and up to 20 km reach. Each module supports 1.25 Gbit/s (1250 Mbit/s) over LC connectors and includes DDM for diagnostics. Designed for compatibility with HP/Aruba equipment, it is suitable for long‑distance uplinks and network aggregation.

## Long description

Extralink SFP WDM 1.25G pair is a set of two fiber optic SFP transceivers designed for single‑mode links using asymmetric wavelengths (1310 nm transmit / 1550 nm receive and vice versa). Each module supports a data rate of 1.25 Gbit/s over LC connectors and is specified for links up to 20 km. The modules include digital diagnostic monitoring (DDM) for live measurement of optical power and temperature and are made for direct compatibility with HP/Aruba switching and routing equipment, enabling simple deployment of long‑distance uplinks and network aggregation.
Advantages
These Extralink SFP WDM modules provide a compact, hot‑swappable solution for extending point‑to‑point fiber links without the need for separate transceivers at each wavelength. The single‑mode design and LC interface ensure low insertion loss and predictable signal performance over distances up to 20 km. Built‑in DDM allows administrators to monitor optical parameters in real time for easier troubleshooting and link validation. Compatibility with HP/Aruba devices simplifies installation in mixed network environments and reduces the need for vendor‑specific parts.
Suitable for
 Long‑distance uplinks between switches, routers, or aggregation points
 Fiber backbone connections within campuses or small data centers
 Linking HP/Aruba network equipment where dedicated compatibility is required
 Point‑to‑point connections where single‑mode WDM saves fiber pairs
Key specifications
 Form factor: SFP (small form‑factor pluggable)
 Wavelengths: 1310 nm / 1550 nm (WDM pair)
 Maximum data rate: 1.25 Gbit/s (1250 Mbit/s)
 Maximum link distance: up to 20 km over single‑mode fiber
 Connector type: LC duplex
 Features: Digital Diagnostic Monitoring (DDM)
 Fiber type: Single‑mode
How to use
Install each SFP module into the appropriate SFP port on the two endpoint devices, ensuring the transmit and receive wavelengths are paired correctly (one module transmitting at 1310 nm while the mate transmits at 1550 nm). Connect the LC fiber cables between the modules, power on the network devices and verify link status via the device interface. Use the equipment management interface to read DDM values for optical power and temperature to confirm correct operation and adequate margins.
Usage recommendations
Use clean, single‑mode LC patch cords and keep fiber connectors free of dust or debris. Verify that device firmware accepts third‑party SFP modules or enable relevant compatibility settings on HP/Aruba equipment if required. For critical links, monitor DDM values after installation and schedule periodic checks to ensure stable optical performance.
