Optický transceiver modul BlueOptics SFP-SR-LC25-BO SFP28 100 m hliník

The BlueOptics SFP-SR-LC25-BO SFP28 is a fiber optic transceiver module engineered for short-range, high-speed data transmission. It supports 25GBASE-SR protocols over multimode fiber and provides reliable optical links up to 100 meters. The module uses an LC duplex connector and is built in an aluminium housing, combining low weight (approx. 20 g) with mechanical durability suitable for rack and chassis installations.

Advantages

This SFP28 transceiver conforms to MSA standards for 25GBASE-SR operation and integrates 850 nm transmitter and receiver components optimized for multimode fiber. The aluminium housing offers physical protection while keeping the module lightweight. The device supports Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472, enabling real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware supports these features. Components from established suppliers are used to ensure consistent performance and extended operational lifetime.

Suitable for

• Data centre switch uplinks and server connections
• High-speed LAN links within campus or enterprise environments
• Storage systems and fibre-channel over Ethernet applications
• Short-reach optical links in routers, load balancers and modular chassis

Key specifications

• Interface type: SFP28 supporting 25GBASE-SR
• Fiber type: Multimode fiber (MMF)
• Wavelength: 850 nm (transmit and receive)
• Maximum reach: up to 100 meters (typical for multimode OM3/OM4 depending on link design)
• Connector: LC duplex
• Housing: aluminium
• Weight: approximately 0.02 kg
• Digital diagnostics: DDM/DOM (SFF-8472) support when enabled by host

How to use

Insert the SFP28 transceiver into a compatible SFP28 port until it seats firmly and engage any retention mechanism provided by the host. Connect an LC duplex multimode patch cable between the transceiver and the corresponding device or patch panel, observing correct transmit/receive orientation. Ensure the host device supports 25GBASE-SR SFP28 modules and enable DDM/DOM in management firmware if diagnostic monitoring is required. Follow standard ESD precautions when handling the module and keep dust caps on unused ports to protect optical interfaces.

Recommendations

For optimal performance, use OM3 or OM4 multimode fiber and high-quality LC duplex patch cords. Verify compatibility with the target switch, router or storage system and test the link after installation. If DDM/DOM values are required for monitoring, confirm the host device supports reading SFF-8472 parameters. Keep optical connectors clean and avoid tight bends in the fiber to maintain signal quality.
