SFP transceiver module BlueOptics 1442140G2 Fiber optic 1250 Mbit/s

The BlueOptics 1442140G2 Fiber optic SFP transceiver module provides a compact, hot-pluggable solution for 1.25 Gbit/s single‑fiber connections in network equipment. Designed according to SFP form‑factor standards, this silver-coloured module weighs approximately 20 g and supports optical data transmission at a maximum rate of 1250 Mbit/s. It is intended for use in switches, routers and other network devices that accept SFP optics and enables fibre-based links with immunity to electromagnetic interference.

Advantages

The module’s SFP interface and lightweight metal housing allow easy insertion and removal from SFP ports while maintaining mechanical stability. Supporting a maximum data transfer rate of 1250 Mbit/s, the transceiver is suitable for standard 1.25 Gbit/s Ethernet or related optical protocols. The silver finish and compact dimensions ensure compatibility with typical SFP slots and rack‑mounted network hardware. Fibre optic transmission reduces EMI vulnerability compared to copper links and supports longer distances depending on fibre type and link design.

Suitable for

• 1.25 Gbit/s Ethernet links in switches and routers
• Inter-device fibre connections in data centers and server rooms
• Upgrading or replacing existing SFP optical modules
• Applications requiring EMI‑resilient optical links

Key specifications

• Interface type: SFP (small form‑factor pluggable)
• Maximum data transfer rate: 1250 Mbit/s
• Product colour: Silver
• Weight: 0.02 kg

How to use

Ensure the target device supports SFP transceiver modules and is powered down or in a hot‑swap state per the device manual. Remove the protective dust cap from the fibre connector before insertion. Insert the BlueOptics 1442140G2 module into the SFP slot until it latches, then connect the appropriate LC patch cable or mating transceiver. Verify link status through the host device’s management interface and confirm the operational data rate. To remove the module, release the latch mechanism and pull the transceiver straight out, then replace protective caps to protect the fibre port.

Recommendations

Handle the module and fibre connectors with care to avoid contamination. Use compatible singlemode or multimode fibre and matching patch cables per your network design. Confirm that the host equipment supports the required optical protocol and any digital diagnostics features before deployment. Store unused modules in anti‑static packaging and avoid exposing them to liquids or excessive dust.
