Detailed Specifications
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).
