SFP-transceiver BlueOptics AFBR-5718PZ 1250 Mbit/s 850 nm

The BlueOptics AFBR-5718PZ is an SFP fiber optic transceiver designed for 1.25 Gbit/s (1250 Mbit/s) short-range links over multimode fiber. It operates at a wavelength of 850 nm, uses a duplex LC connector and is housed in a metal enclosure with a silver finish. The transceiver runs from a 3.3 V supply and has a compact SFP form factor and a lightweight design of approximately 20 g, suitable for integration into switches, routers and other network devices that accept SFP modules.

Advantages

This module supports 1000Base-SX Ethernet and is compatible with MSA-compliant SFP ports. The design includes separate transmitter and receiver components optimized for multimode fiber, enabling reliable data transfer at gigabit speeds over typical campus and data center distances. The metal housing provides mechanical robustness and EMI protection, while the low power supply requirement simplifies deployment in standard networking equipment.

Suitable for

• Short-range gigabit Ethernet links over multimode fiber
• Upgrading switches and routers with SFP ports to 1.25 Gbit/s
• Data center and campus backbone connections up to multimode reach limits
• Compatibility testing and replacement of original 1000Base-SX SFP modules

• Wavelength: 850 nm
• Connector: LC duplex (multimode fiber)
• Power supply: 3.3 V
• Housing: metal, silver colour
• Weight: ~20 g

How to use

Insert the BlueOptics AFBR-5718PZ into a compatible SFP slot of the network device while the device is powered according to the host equipment's instructions or hot-plug per the manufacturer's guidance. Connect LC duplex multimode fiber patch cords to the module, ensuring correct transmit-to-receive alignment between link endpoints. Verify link status via the host device management interface and configure the interface for 1000Base-SX operation if required by the equipment. Follow standard ESD precautions when handling the transceiver and keep the protective dust caps on the optical ports until fiber connection.

Recommendations

Use the transceiver with multimode fiber of appropriate grade (e.g., OM3/OM4 for extended reach) and LC duplex connectors. Confirm compatibility with the host device's supported optics list or perform an interoperability test before large-scale deployment. Store unused modules in anti-static packaging and avoid exposure to dust or direct sunlight to preserve optical performance.
