Detailed Specifications
HPE JH648A 1 Gb SFP Transceiver Module 1000BASE SX MMF
Overview
The HPE JH648A is a 1-Gigabit small-form-factor pluggable (SFP) optical transceiver designed for enterprise fibre links in access or aggregation networks. It uses the 1000BASE-SX standard over multimode fibre, supports an 850 nm wavelength and is rated for distances up to approximately 550 m in multimode fibre environments. This module plugs into standard SFP slots in HPE/Arista switches and similar equipment, enabling cost-effective fibre uplinks where copper is undesirable or impractical. A typical use case: connecting wiring-closet switches to building backbone fibre or linking access switches in a campus across a short multistory building.
Key Features
Supports 1 Gbps data rate using 1000BASE-SX over multimode fibre for fibre-based uplinks in enterprise networks.
850 nm VCSEL-based optical transmitter paired with duplex LC connector; rated to ~550 m reach on MMF under standard conditions.
Hot-swappable SFP form-factor module with duplex LC interface×fits SFP cages in HPE/Arista platforms and maintains modular flexibility.
Multi-source agreement (MSA) compliant and widely compatible across equipment that accepts HPE/Arista SFPs; practical for field replacements in heterogeneous environments.
