J4859B HPE 1GBPS SFP 1000Base-LX - LC Full Duplex Plug-in Refurbished

J4859B is an Ethernet wired transceiver module, commonly known as an SFP (Small Form-factor Pluggable) module, manufactured by Hewlett-Packard Enterprise (HPE). It is designed to be used with HPE network equipment to provide a high-speed and reliable network connection.

The J4859B SFP module supports 1000Base-LX Ethernet standard, which enables data transfer at a speed of 1 gigabit per second (Gbps). It uses an LC connector to interface with the network equipment and is compatible with both single-mode and multi-mode fiber optic cables.

Full duplex communication is supported by this module, which means that data can be transmitted and received simultaneously, enhancing network performance and efficiency.

The J4859B SFP module is built to deliver high reliability and performance, ensuring that data is transmitted without any loss or delay. The module also supports digital optical monitoring (DOM) functions, which allows for real-time monitoring of the module's operational parameters such as temperature, optical power, and voltage.

J4859B is a 1Gbps SFP (Small Form-factor Pluggable) transceiver module manufactured by Hewlett Packard Enterprise (HPE). It is designed for Ethernet wired networks and supports the 1000Base-LX standard, which provides a data transfer rate of 1 Gbps over a single mode fiber optic cable.

The module features an LC connector, which is a small form-factor fiber optic connector commonly used in data center and telecommunications environments. The LC connector provides reliable and secure fiber optic connectivity and is easily interchangeable with other LC connectors.

Maintenance and troubleshooting of the J4859B module depend on the network environment and the issues encountered. Here are some general tips for maintaining and troubleshooting the module:

• Ensure that the module is installed correctly and securely in the SFP port of the switch or router. If the module is not inserted properly, it may cause connectivity issues.
• Check the compatibility of the module with the switch or router. Ensure that the device is capable of supporting the J4859B module.
• Ensure that the fiber optic cable is compatible with the module and is properly connected to the LC connector. Use high-quality fiber optic cables to ensure reliable data transmission.
• Use diagnostic tools to troubleshoot issues with the module. Many switches and routers have built-in diagnostic tools that can help identify issues with the module or the fiber optic cable.
• Check for any physical damage to the module or the fiber optic cable. If the module or cable is damaged, it may need to be replaced.
• Update the firmware of the switch or router to ensure that it is compatible with the J4859B module.
