Fully plug and play—no coding, no configuration, no firmware updates.

3.Engineered for Reliability & Low EMI

Shielded RJ45 port minimizes electromagnetic interference

Die-cast zinc housing ensures superior heat dissipation

Gold-plated contacts enhance durability and signal integrity

Important Usage Notes and Safety Guidelines

To ensure optimal performance and long-term reliability of the RJ45 SFP copper transceiver, please observe the following guidelines:

1. Handle with care – guard against electrostatic damage

Avoid direct contact with gold-plated contacts or RJ45 pins when handling the module to prevent electrostatic discharge (ESD) causing permanent damage to internal circuitry.

2. Insert Only into Compatible SFP Ports

This module conforms to the 1000BASE-T SFP specification and is designed exclusively for 1G Ethernet networks. Never insert into SFP+ (10G), QSFP, or non-SFP slots. Forced insertion into incompatible ports may cause physical or electrical damage.

3. Use standard Ethernet cables

Only Cat5e/6/6a/7 specification cables are supported. Damaged, substandard, or excessively long cables may cause link instability and reduced data rates.

4. Normal operating heat generation

During standard operation, the module surface may become warm to the touch—this is attributable to the integrated physical layer controller's power consumption. Provided the switch is positioned in a well-ventilated environment with ambient temperatures maintained between 0°C and 70°C, moderate heat emission does not constitute a fault.

5. Avoid Dust and Moisture

Keep RJ45 ports clean and properly protected when not in use. Dust, moisture, or corrosion on connectors may degrade signal integrity.

  • 4 PCS RJ45 1000Base-T: The RJ45 optical module supporting 1.25G rate transmission. As an SFP transceiver, it operates with Cat5e/6/6a/7 cables for stable transmission up to 100 meters (328 Ft), compliant with SFF-8431 MSA standards and IEEE 802.3. Operating Temperature: 0°C to 70°C
  • Plug and Play & Hot-Pluggable Design：The network transceiver requires no software configuration, network downtime, or reboots. Simply insert the 1G-T-S module into a compatible SFP+ port, connect an RJ45 Ethernet cable, and it's ready to go—enabling rapid network upgrades
