SFP transceiver module BlueOptics SIAE-E01428-BO 1250 Mbit/s 850 nm

The BlueOptics SIAE-E01428-BO SFP transceiver module is a compact fiber optic transceiver designed for 1000Base-SX networks. It supports a maximum data rate of 1250 Mbit/s over multimode fiber using an 850 nm wavelength and features an LC duplex connector that enables simultaneous transmit and receive channels. The module is housed in a durable metal casing, requires a 3.3 V supply, and weighs approximately 4 g, making it suitable for dense installations and environments where space and weight are important.

Advantages

This SFP module follows MSA standards and is compatible with devices that support the referenced form factor and protocol, providing plug-and-play replacement capability for systems that accept 1000Base-SX SFPs. Built with quality optical and electronic components, it supports reliable transmission over multimode fiber and offers digital diagnostics monitoring (DDM/DOM) when supported by host hardware. The small metal housing provides mechanical protection and EMI resilience compared with plastic modules.

Key specifications

How to use

Insert the SFP module into a compatible SFP port on a switch, router or other networking device until it clicks into place, then secure any retention mechanism the host provides. Connect an LC duplex multimode fiber patch cable matching the module's transmit and receive lanes. Ensure the host device is configured for the optical interface and that link speed/auto-negotiation settings match network requirements. If the host supports Digital Diagnostics Monitoring, enable or query the DDM/DOM registers for real-time information on optical power, temperature, bias current and supply voltage.

Recommendations

Use multimode fiber (OM1/OM2/OM3/OM4) appropriate for the intended link distance, keep connectors clean to avoid signal loss, and verify compatibility with the host device. For best results, test the link after installation and monitor DDM/DOM values where available to detect issues early.
