SFP transceiver modul BlueOptics 943 974-001-BO 1250 Mbit/s vlákno

The BlueOptics 943 974-001-BO SFP transceiver module is a single-mode fiber optic SFP designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. It uses an LC (UPC) simplex connector and supports optical links up to 20,000 m. The module is supplied at 3.3 V, comes in a silver housing and matches the compact SFP form factor with dimensions of approximately 13.9 mm (W) × 58.4 mm (D) × 12.6 mm (H). This device is compatible with Hirschmann platforms that accept the corresponding SFP type and is intended for Ethernet, Fibre Channel over Ethernet and SDH/SONET applications up to 1.25 Gbit/s.

Advantages

The transceiver follows MSA-compliant SFP mechanical and electrical specifications, enabling plug-and-play interoperability with Hirschmann hardware that supports equivalent SFP modules. It offers a long optical reach of up to 20 km over single-mode fiber and uses an LC (UPC) connector for reliable simplex connections. The module is compact and lightweight (about 0.02 kg), minimizing space and weight impact in dense networking racks. Where supported by the host hardware, digital diagnostics (DDM/DOM) provide real-time monitoring of supply voltage, laser bias current, output power, received power and temperature for easier maintenance and troubleshooting.

Suitable for

• Gigabit Ethernet uplinks and long-distance fiber links
• Switches, routers and storage systems that accept MSA SFP transceivers
• Fibre Channel over Ethernet and SDH/SONET links up to 1.25 Gbit/s
• Industrial and enterprise networks requiring single-mode LC simplex connections

Key specifications

• Maximum data transfer rate: 1250 Mbit/s
• Maximum transfer distance: 20000 m (single-mode fiber)
• Fiber optic connector: LC (UPC) simplex
• Supply voltage: 3.3 V
• Product colour: Silver
• Weight: 0.02 kg
• Form factor: SFP (small form-factor pluggable)

How to use

Insert the BlueOptics SFP transceiver into a compatible SFP slot on a switch, router or other network device while the host is powered down or following the vendor’s hot-swap procedure. Connect a single-mode fiber patch cable with LC (UPC) connectors to the module’s LC simplex port, observing correct Tx/Rx orientation. Verify link status and, if applicable, access the host device management interface to confirm detected link speed and digital diagnostic readings. Follow the host equipment vendor’s instructions for any required software or compatibility settings.

Recommendations

Use high-quality single-mode fiber patch cords and, when possible, patch panels or mate the module directly to another compatible SFP transceiver to achieve the specified 20 km range. Ensure the host device supports MSA SFP modules and DDM/DOM if you require real-time diagnostic monitoring. Keep connector end faces clean and protected when not in use to maintain signal quality and link reliability.
