FAQ
What is the difference between 1000BASE-BX20-D and other SFP transceivers?
The 1000BASE-BX20-D designation indicates this is a downstream bidirectional transceiver that operates on a single strand of single-mode fiber optic cable. Unlike standard dual-fiber transceivers, BX transceivers use wavelength division multiplexing to transmit and receive on different wavelengths over the same fiber, reducing fiber infrastructure requirements. The 'D' suffix specifically denotes the downstream direction in a bidirectional link pair.
Which HP ProCurve switches are compatible with this SFP transceiver?
This transceiver is compatible with multiple HP ProCurve switch models including the V1400-24G, 2520 series (J9137A, J9138A, J9298A, J9299A), E2650 series (J4899C, J8165A), E2626 series (J4900C, J8164A), and 2610 series (J9089A, J9086A). The module is MSA compliant and designed to work with HP switches that support 1000BASE-BX SFP transceivers without requiring special firmware or configuration.
What type of fiber optic cable should I use with this transceiver?
This transceiver requires single-mode fiber optic cable with LC connectors. Single-mode fiber has a smaller core diameter (typically 9µm) that allows light to travel in a single path, enabling longer transmission distances with less signal loss compared to multimode fiber. For 1000BASE-BX20-D operation, you'll need standard single-mode fiber patch cables with LC connectors that meet the distance requirements of your specific installation.
Does this SFP transceiver support digital diagnostics monitoring?
Yes, this transceiver includes digital diagnostics monitoring (DDM) capabilities as per the SFP MSA specification. DDM allows network administrators to monitor real-time parameters including optical transmit power, optical receive power, temperature, supply voltage, and laser bias current. This information can be accessed through the switch's management interface for proactive network monitoring and troubleshooting.
What is the maximum distance this transceiver can support?
The 1000BASE-BX20-D specification typically supports distances up to 20 kilometers over single-mode fiber, though actual performance may vary based on fiber quality, connector losses, and environmental conditions. This extended reach makes the transceiver suitable for campus networks, metropolitan area connections, and other applications requiring longer-distance fiber links between network devices.
Is this transceiver hot-pluggable?
Yes, this SFP transceiver is hot-pluggable, meaning it can be inserted or removed from a compatible switch's SFP port without powering down the switch. This feature allows for easy installation, replacement, or reconfiguration of network connections without disrupting other switch operations. Always follow proper electrostatic discharge (ESD) precautions when handling optical transceivers.
