HP JL439A X130 10G Sfp+ Lc Lr SMF, 1310nm, 10km, LC, DOM Transceiver

HPE JL439A – 10-G SFP+ LR Transceiver Module

Overview

The HPE JL439A is a hot-pluggable 10-Gigabit SFP+ transceiver aimed at network engineers needing long-haul single-mode fiber (SMF) links between switches, routers or media converters. It supports IEEE 802.3ae 10GBASE-LR (1310 nm) specification and addresses links of up to approximately 10 km over single-mode fiber—useful for campus core-to-aggregation or data-hall interconnects. The module fits into standard SFP+ cages on HPE switches and compatible platforms and offers LC duplex connectivity. Because you’ve installed gear inside racks and patched fiber trunks yourself, you know that matching the form-factor and optical budget is critical—this module does both. It is best placed in aggregation/distribution layers or inter-building fiber runs, rather than short multi-mode links.

Key Features

• 10 Gbps 10GBASE-LR support over SMF for up to ~10 km—covers longer campus or small data-centre spans.

• Duplex LC connector for standard fiber patching at SFP+ ports.

• 1310 nm wavelength ensures compatibility with long-reach SMF optics in enterprise networks.

• Hot-swappable module—can install or replace without powering down the switch.

• Digital Optical Monitoring (DOM) capable in many implementations—monitor real-time optical parameters (power, temperature).
