Πομποδέκτης SFP HPE X121 1G RJ45 T

The HPE X121 1G SFP RJ45 T is a compact copper SFP transceiver designed for 1000BASE-T wired Ethernet connections. Supporting a maximum data rate of 1000 Mbit/s and compliant with IEEE 802.3ab standards, this module provides standard Gigabit connectivity in SFP form factor. With a typical power consumption of approximately 1 W and a small lightweight design, it is suitable for use in switches, routers and other networking equipment that accept SFP RJ45 modules.

Advantages

This SFP RJ45 module delivers standardized 1 Gbit/s copper connectivity in a small form factor compatible with SFP ports. Compliance with IEEE 802.3ab ensures interoperability with other 1000BASE-T equipment. Low typical power consumption reduces heat output and energy use in dense installations, while the lightweight and compact design helps save space in chassis-based systems.

Suitable for

• Upgrading SFP ports to support Gigabit copper connections
• Short to medium-length copper Ethernet links between network devices
• Data center top-of-rack switches requiring copper SFP modules
• Telecommunications and enterprise network edge devices

Key specifications

• Interface: 1000BASE-T over RJ45 (SFP form factor)
• Maximum data transfer rate: 1000 Mbit/s
• Standards compliance: IEEE 802.3ab
• Typical power consumption: ~1 W
• Weight: 0.03 kg
• Physical form factor: SFP (small form-factor pluggable)

How to use

Insert the transceiver into an available SFP port on a compatible switch, router or network appliance until it seats firmly. Connect a Category 5e/6/6a Ethernet cable to the RJ45 port on the transceiver and to the remote device. Verify link and activity indicators on the host device to confirm a negotiated 1 Gbit/s connection. Follow the host equipment manufacturer’s instructions for hot-plugging and firmware compatibility checks before deployment.

Recommendations

Use high-quality shielded or unshielded twisted-pair Ethernet cabling rated for Gigabit speeds (Cat5e or higher) and ensure connectors are properly terminated. For dense installations, check the host device documentation for supported SFP modules and power/thermal limits. Keep firmware and device compatibility information up to date to ensure stable links.
