Extralink SFP 1.25G WDM-modulepaar 1310/1550nm singlemode 3km SC DOM voor HP/Aruba

The Extralink SFP 1.25G WDM module pair 1310/1550nm single‑mode 3km SC DOM for HP/Aruba is a matched set of small form-factor pluggable transceivers designed for single‑mode fiber links. Each module supports a data rate up to 1.25 Gbit/s and operates with WDM wavelengths at 1310 nm and 1550 nm to enable bidirectional transmission over a single fiber. The pair includes SC connectors, digital optical monitoring (DOM) capability and a maximum reach of approximately 3 km. These modules are supplied as a dedicated pair for installation in SFP slots of HP/Aruba equipment, intended for fiber uplinks and device interconnects in LAN and WAN environments.

Advantages

The modules provide WDM bidirectional transmission over a single strand of single‑mode fiber, reducing cabling complexity while maintaining full duplex connectivity at 1.25 Gbit/s. DOM support enables real‑time monitoring of optical parameters for improved diagnostics and maintenance. Certified compatibility with SFP interfaces and provided as a matched pair simplifies integration into HP/Aruba systems and helps ensure reliable link negotiation and performance.

How to use

Install each SFP module into the SFP slot of the corresponding HP/Aruba device, ensuring the modules are used as the matched pair with correct orientation for the 1310/1550 nm WDM roles. Connect the SC fiber patch cords to the modules and secure connections to maintain optical performance. After physical installation, verify link status on the devices and check DOM readings for optical power, temperature and other diagnostics. Configure the network interfaces on the connected equipment as required for gigabit fiber links.

Recommendations

Use factory‑matched pairs and maintain clean SC connectors to preserve signal quality. Verify device compatibility with HP/Aruba SFP slot firmware requirements before deployment and monitor DOM values during initial commissioning and routine maintenance to detect signal degradation early.
