HPE 1990-4116 – 1 Gb/s LX SFP Transceiver
Overview :
The HPE Aruba 1990-4116 is a 1 Gb/s LC‑connector SFP (mini‑GBIC) optical transceiver designed for network engineers deploying Gigabit Ethernet links over single‑mode fibre. It supports 1000Base‑LX operation at a wavelength of 1310 nm and reaches up to approximately 10 km, solving the need to extend gigabit connectivity beyond short‑reach copper or multimode links. This module is suitable for campus backbone, data‑centre uplinks or inter‑building links rather than access‑layer switching in branch offices. The transceiver integrates with HP/Aruba switches and is compatible with platforms that support the J4859D family; it also supports DOM/monitoring for optical diagnostics and fits standard SFP cages.
Key Features :
-
1000Base‑LX 1 Gb/s throughput over fibre
-
1310 nm wavelength for long‑reach SMF links
-
Duplex LC connector interface for SFP cage compatibility
-
Reaches approximately 10 km over 9/125 µm single‑mode fibre
-
Supports digital optical monitoring (DOM) for diagnostics
