SFP transceiver BlueOptics 3FE28785AB-BO 1250 Mbit/s Fiber optic

The BlueOptics 3FE28785AB-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data transfer rate of 1250 Mbit/s. The module comes in a metal housing with a silver finish, weighs approximately 20 g and is specified with a high MTBF of 1,000,000 hours. It conforms to MSA SFP mechanical and electrical standards and uses an LC simplex optical connector with separate transmitter and receiver wavelengths for bidirectional single-fiber operation.

Advantages

This BlueOptics SFP transceiver is compatible with widely used hardware platforms that accept standard SFP modules and supports transmission distances typical for single-mode optical links. Built to MSA standards, it provides digital diagnostic monitoring (DDM/DOM) capability where supported by the host device, enabling real-time monitoring of supply voltage, laser bias current, transmitted and received optical power, and temperature. The metal housing and component selection aim to provide stable performance and a long service life suitable for continuous network operation.

Suitable for

• 1000BASE-BX-D single-mode Ethernet links up to typical single-mode distances
• Interconnects between switches, routers and storage systems that accept SFP modules
• Applications requiring DDM/DOM monitoring for remote diagnostics
• Replacement or upgrade of compatible vendor SFP transceivers in MSA-compliant ports

Key specifications

• Interface type: SFP
• Maximum data transfer rate: 1250 Mbit/s
• Optical connector: LC simplex (single-mode, bidirectional wavelengths)
• Transmitter/receiver wavelengths: typical BX pair (separate TX and RX wavelengths for single-fiber operation)
• Housing material and colour: metal, silver
• Weight: 0.02 kg
• Digital Diagnostics: DDM/DOM (when supported by host hardware)
• Compliance: MSA SFP mechanical/electrical compatibility; meets common industrial standards for optical modules

How to use

Install the SFP transceiver into an empty MSA-compliant SFP port on a switch, router or other host device while the host is powered according to the vendor guidelines. Connect a single-mode LC simplex fiber patch cord to the module and to the remote transceiver, ensuring the correct alignment of BX wavelengths for bidirectional single-fiber links. Verify link status and, if available, enable or read DDM/DOM parameters via the host management interface to monitor optical power, temperature and supply parameters. Follow the host equipment manual for any platform-specific configuration or compatibility settings.

Recommendations

Use this module in MSA-compliant SFP ports and pair it with appropriate single-mode LC patch cords and compatible remote transceivers. Confirm DDM/DOM support on the host device before relying on diagnostics. Store and handle the transceiver and fiber connectors according to standard ESD and optical cleanliness practices to maintain signal quality and module lifetime.
