Installation and Configuration of Ethernet Transceiver

The J4859A HPE SFP Gigabit Ethernet 1000Base-LX Transceiver Module is a Small Form-factor Pluggable (SFP) transceiver that can be used to provide Gigabit Ethernet connectivity over single-mode fiber-optic cable. To install the module, follow these steps:

  • Power off the device that the module will be installed in.
  • Remove the module from its static-protective packaging.
  • Carefully align the module with the SFP port on the device, and gently push it in until it clicks into place.
  • Power on the device.

For Configuration:

  • Log into the device's management interface.
  • Navigate to the interface configuration for the port that the J4859A is connected to.
  • Configure the port to operate at 1000Mbps full-duplex.
  • Configure the port to use the appropriate optical parameters for the fiber-optic cable in use (e.g. wavelength, maximum distance).
  • Save the configuration and verify that the link comes up and is operational.
Connector and Cable Compatibility

The J4859A HPE SFP Gigabit Ethernet 1000Base-LX Transceiver Module is a type of SFP (small form-factor pluggable) transceiver that is used to connect a network device, such as a switch or router, to a fiber optic cable. The module is compatible with 1000Base-LX standard, which specifies a data transfer rate of 1 Gbps over single-mode fiber optic cable with a maximum distance of 10 km (6.2 miles).

In terms of connector compatibility, the J4859A module uses an LC (Lucent Connector) type connector, which is a small, duplex connector that is commonly used in fiber optic networking. It must be matched with LC connector in the other end of the fiber optic cable.

Quality of Service and Performance

Quality of Service (QoS) and performance are key factors to consider when selecting a transceiver module for your network. The J4859A HPE SFP Gigabit Ethernet 1000Base-LX transceiver module offers high-quality performance for your network.

Quality of Service (QoS) refers to the ability of a network to provide a certain level of performance to specific types of data. In the case of the J4859A, it supports Quality of Service (QoS) by prioritizing certain types of data, such as voice and video, over other types of data. This ensures that important data is delivered with minimal delay and interruption.

Performance is another important factor to consider when selecting a transceiver module. The J4859A offers high-performance with a data rate of up to 1 Gbps and a wavelength of 1310 nm. It also supports a wide range of distances, up to 10km, allowing for flexible deployment options. Additionally, it has a robust design and is compliant with industry standards, ensuring reliability and stability in your network.
