HPE J4859C Aruba - SFP (mini-GBIC) transceiver module - GigE

The HPE J4859C is a small form-factor pluggable (SFP) Gigabit LX transceiver designed to provide reliable, long-range fiber optic connectivity for enterprise and service provider networks. This module addresses the need for extending Gigabit Ethernet links well beyond the distance limitations of standard copper cabling, making it an essential component for interconnecting buildings, floors, or wiring closets. It delivers a full-duplex, 1 Gbps connection, ensuring a stable and high-performance data link for critical network infrastructure. The primary function of this transceiver is to convert electrical signals into optical signals for transmission over fiber optic cables, solving challenges related to distance and electromagnetic interference in sprawling network environments. Engineered for versatility, this transceiver utilizes a 1310 nm wavelength laser, enabling it to support both multimode and single-mode fiber optic cables. Over standard multimode fiber, it can achieve link distances up to 550 meters, which is ideal for campus network backbones. For long-haul connections, it excels over single-mode fiber, supporting distances up to 10 kilometers (6.2 miles), a capability critical for metropolitan area networks (MAN) or large-scale campus deployments. Its low power consumption of less than 1 watt ensures operational efficiency and reduces thermal load within high-density switches and routers. As a hot-swappable module with a standard SFP footprint, the J4859C simplifies deployment and maintenance, allowing network administrators to add or replace transceivers without service interruption. It plugs into any SFP-compatible port on a wide range of HPE and Aruba networking devices, including switches and routers, providing a flexible and scalable solution for network expansion. Management is straightforward, with Digital Diagnostics Monitoring (DDM) support that allows real-time access to operating parameters such as optical output power, input power, temperature, and supply voltage, enabling proactive network maintenance.
