Detailed Specifications
HPE JD494A - 1000Base-LX SFP Transceiver Module
Overview :
The HPE JD494A is a hot-pluggable SFP (mini-GBIC) optical transceiver designed for network engineers deploying 1 Gigabit Ethernet links over fiber. It supports the IEEE 802.3z 1000Base-LX standard and is suited for single-mode fiber links up to 10 km. In typical network architectures this module is used in data center, campus aggregation or branch uplinks where long-reach fiber connectivity is required. It installs into SFP ports on switches, routers or servers and interoperates with LC-duplex connectors and a 3.3 V supply rail. The JD494A enables fibre link extension without moving to 10 Gb/s optics when 1 Gb/s remains sufficient, and integrates with standard SFP-M^2 multi-source agreement platforms.
Key Features :
Supports 1.25 Gb/s link rate for Gigabit Ethernet
Operates at 1310 nm wavelength over SMF
Duplex LC connector interface for fibre ports
Reach up to 10 km on 9/125 µm single-mode fibre
Single +3.3 V power supply, MSA compliant footprint
