SFP transceiver module BlueOptics E1MG-TX Copper 1250 Mbit/s

The BlueOptics E1MG-TX Copper SFP transceiver module supports a maximum data transfer rate of 1250 Mbit/s and is designed for use in devices with SFP interfaces. This compact module provides a copper electrical interface for short-reach connections over twisted-pair copper cabling, enabling integration into switches, routers and other network equipment that accept standard SFP form-factor devices.

Advantages

The module offers a standardized SFP form factor for easy hot-plug installation and broad compatibility with SFP-enabled network ports. Its copper interface eliminates the need for fiber cabling in short-distance links, simplifying deployment and reducing material costs. With support for up to 1250 Mbit/s data rates, the transceiver is suitable for typical Ethernet and telecom applications that require reliable, single-channel transmission.

Suitable for

• Short-reach Ethernet connections over copper cabling
• Upgrading or replacing SFP ports in switches and routers
• Network equipment testing and lab environments
• Single-channel links in telecom and data center access layers

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Interface: Copper electrical interface for twisted-pair cabling
• Maximum data transfer rate: 1250 Mbit/s
• Transmission mode: Single-channel bidirectional data
• Compatibility: Designed for SFP-compliant ports on network devices

How to use

Power down the host device if recommended by the equipment manufacturer, then insert the BlueOptics E1MG-TX module into an available SFP slot until it latches. Connect the appropriate copper patch cable to the module's RJ-style interface and to the corresponding network device. After insertion, confirm link and activity LEDs on the host device or check the management interface to verify the module is recognized and operating at the expected speed. Follow any device-specific configuration steps required to enable the port.

Usage recommendations

Use the transceiver with compatible SFP ports and CAT5e or better copper cabling for reliable operation at near distances. Ensure firmware and device compatibility where vendor lock or port validation is enforced. Store unused modules in antistatic packaging and avoid exposure to moisture or extreme temperatures.
