HPE JD119B X120 1G SFP LC LX Transceiver
Overview
The HPE X120 1G SFP LC LX Transceiver is an enterprise-grade optical module engineered to deliver reliable, long-range Gigabit Ethernet connectivity. Designed for deployment in switches and routers within campus and data center networks, this hot-swappable SFP transceiver addresses the need for cost-effective fiber links that extend well beyond the reach of standard copper cabling, providing a stable 1 Gbps connection over distances up to 10 kilometers. This module operates over the 1000BASE-LX standard, utilizing a 1310nm wavelength to transmit data efficiently over single-mode fiber (SMF). Its core value lies in its flexibility, as it also supports connections over multi-mode fiber (MMF) up to 550 meters, making it a versatile solution for various structured cabling environments. This dual-capability allows network administrators to standardize on a single transceiver model for different link distance requirements, simplifying inventory and procurement. The transceiver’s low power consumption, typically under 1 watt, contributes to reduced operational costs and lower heat dissipation in high-density deployments. As a plug-in module, the JD119B is installed into an SFP port on a compatible HPE networking device, instantly enabling a fiber optic interface. Its small form-factor and LC duplex connector are industry standards, ensuring broad compatibility and straightforward implementation in existing infrastructure. Management is handled through the host device’s command-line interface (CLI) or network management platform, where technicians can monitor transceiver status and performance metrics through Digital Diagnostics Monitoring (DDM).
