Detailed Specifications
HPE JL747A - 1 Gb RJ-45 Copper SFP Transceiver (100 m)
Overview
The HPE JL747A is a compact SFP-form-factor copper transceiver designed for network engineers who need to plug into existing RJ-45 copper infrastructure while using SFP ports on switches or routers. For example, if you have a backbone switch with spare SFP slots but your endpoint panel uses Cat5e copper runs, this module lets you bridge that gap without switching to fibre. It supports Gigabit Ethernet (1000BASE-T) over twisted-pair cable up to 100 meters. The module is suited for wiring closets or server racks where copper is preferred or already installed and fibre is not necessary. It's TAA-compliant, making it an option in procurement scenarios requiring Trade Agreements Act compliance.
Key Features
1 Gb-rated copper transceiver enabling 1000BASE-T data links over standard Cat5e/Cat6 cable up to ~100 m.
RJ-45 connector form in SFP module housing×fits into SFP-slot ports designed for copper SFPs.
TAA-compliance for environments where procurement compliance is required.
Ideal for mixed fibre/copper networks: allows use of copper link segments in switches with SFP ports.
Minimizes infrastructure change when adding or repurposing SFP slots for copper runs rather than fibre upgrades.
