Modulo ricetrasmettitore SFP28 BlueOptics 91C9R-BO LC alluminio

The BlueOptics 91C9R-BO LC Aluminium is an SFP28 fiber optic transceiver module designed for 25G high-speed data transmission over multimode fiber. It uses an LC duplex connector and an aluminium housing, and weighs approximately 20 g. The module implements 25GBASE-SR optical signalling with 850 nm wavelength for both transmitter and receiver, and follows MSA standards for form factor and interoperability with compatible 25G-capable network equipment.

Advantages

The transceiver provides a compact SFP28 form factor that supports up to 25 Gbit/s data rates, an LC duplex interface for simultaneous send and receive channels, and an aluminium housing that offers physical protection and thermal performance. It is manufactured to industry MSA specifications, enabling plug-and-play compatibility with equipment that supports 25G SFP28 SR modules. The module is lightweight and suitable for dense installation in switch and router ports.

Suitable for

• 25G Ethernet links over multimode fiber
• High-speed interconnects between switches, routers and storage systems
• Data center aggregation and top-of-rack connections up to ~100 m
• Environments requiring MSA-compliant SFP28 modules with LC connectors

Key specifications

• Interface type: SFP28
• Optical wavelength: 850 nm (transmit and receive)
• Supported data rate: up to 25 Gbit/s
• Connector: LC duplex
• Fiber type: multimode fiber (MMF)
• Typical reach: up to ~100 meters on suitable MMF
• Housing material: aluminium
• Weight: approx. 0.02 kg

How to use

Install the SFP28 transceiver into a compatible SFP28 port on your switch, router or storage device following the host equipment vendor’s handling guidelines. Connect LC duplex multimode fiber patch cords to the module and the corresponding port or patch panel, observing correct transmit-to-receive polarity. Ensure the host device firmware and software support 25G SFP28 SR modules and, if required, enable any vendor-specific settings. Verify link status and performance through the host device management interface after installation.

Recommendations

For optimal performance, pair the module with OM3/OM4 multimode fiber and high-quality LC patch cords; maintain clean connector end-faces and use dust caps when the transceiver is not in use. If digital diagnostic monitoring (DDM/DOM) is supported by your equipment, use it to monitor supply voltage, laser bias current, output power, received power and temperature for proactive maintenance.
