Lenovo RJ45 1GBPS Transceiver

Overview

The Lenovo 00FE333 is a small-form-factor transceiver module designed to provide 1000 Mbps Ethernet connectivity through existing copper cabling. It fits into any switch, router, or server with an open SFP or mini-GBIC slot, enabling gigabit performance over Category 5, 5e, or 6 cables up to 100 meters. This module supports hot plugging, allowing installation or replacement without powering down equipment, which helps maintain network uptime during upgrades or maintenance.

Key features

• 1000Base-T support enables gigabit Ethernet over standard copper twisted pair cables, making use of existing infrastructure.
• Hot pluggable design allows for easy installation or replacement without interrupting network operations.
• Automatic negotiation of speed and duplex mode via IEEE 802.3ab and 1000Base-X protocols reduces setup time and prevents configuration errors.
• Compact form factor suits dense rack environments where managing heat and space is critical.
• Preserves fiber ports for longer-distance connections by offloading short-range copper links.
• Reliable performance for data centers, campus networks, and branch office wiring closets requiring stable gigabit throughput.
