Lenovo RJ45 1GBPS Transceiver

The Lenovo 00FE333 is a small-form-factor transceiver module that adds 1000 Mbps Ethernet connectivity to any switch, router, or server equipped with an open SFP or mini-GBIC slot. It follows the 1000Base-T specification, allowing you to take advantage of existing Category 5, 5e, or 6 copper cabling while delivering gigabit performance up to 100 meters.

Because the module is hot pluggable, you can install or replace it without powering down your equipment, a benefit that keeps busy networks online during upgrades or maintenance. Support for IEEE 802.3ab and 1000Base-X auto negotiation lets the transceiver detect link partners automatically and select the proper speed and duplex mode, reducing configuration time and helping prevent mismatches.

The design works well in dense rack installations where thermal management is a concern. Network administrators running data centers, campus backbones, or branch office wiring closets can rely on this module to deliver stable gigabit throughput while preserving valuable fiber ports for longer-distance links.

Whether you are expanding an existing copper infrastructure, adding redundancy to critical links, or replacing failed modules in production hardware, the Lenovo 00FE333 offers a straightforward, cost-effective path to wired gigabit performance.

Highlights:

• 1000Base-T SFP transceiver module for gigabit Ethernet over copper
• Plugs into standard SFP or mini-GBIC slots and is hot pluggable
• Supports IEEE 802.3ab and 1000Base-X auto negotiation
• Operates with Category 5, 5e, or 6 twisted pair cables up to 100 meters
• Suitable for rack-dense environments where thermal efficiency matters
