SFP transceiver module BlueOptics 551077-BO Fiber optic 155 Mbit/s

The BlueOptics 551077-BO is an SFP fiber optic transceiver module designed for networking equipment that requires a compact, hot-pluggable interface. With a maximum data transfer rate of 155 Mbit/s and a compact SFP form factor, this silver-coloured module is suitable for legacy and industrial communication links where low-speed optical connectivity and small footprint are needed. The module is lightweight and rated with an MTBF of 1,000,000 hours, indicating a design aimed at long-term, reliable operation.

Advantages

The SFP form factor provides hot-swappable installation and broad compatibility with switches and routers that accept standard SFP modules. The 155 Mbit/s optical data rate supports synchronous optical network and legacy applications while consuming minimal physical space. A mean time between failures (MTBF) of 1,000,000 hours reflects predictable reliability for continuous operation. The module’s small weight and compact dimensions simplify handling and mounting in dense equipment racks.

Suitable for

• Low-speed fiber links in LAN and industrial networks
• Upgrading legacy equipment that requires 155 Mbit/s optical interfaces
• Compact or high-density switch ports where SFP modules are used
• Environments requiring long-term stable optical connectivity

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Maximum data transfer rate: 155 Mbit/s
• Product colour: Silver
• Weight: approximately 0.02 kg
• Reliability: mean time between failures (MTBF) 1,000,000 hours

How to use

Power down the host device or follow hot-swap procedures recommended by the equipment manufacturer, then insert the BlueOptics SFP module into an available SFP slot until it seats securely. Connect the appropriate fiber optic patch cable to the module’s optical receptacle, observing correct transmit/receive orientation. Restore power if required and verify link status using the host device management interface or indicator LEDs. For removal, follow the reverse procedure and handle the module and fiber connectors carefully to avoid contamination or damage.

Recommendations

Keep dust caps on the fiber connector when the module is not in use, and avoid touching the ferrule. Use compatible fiber cable types and follow the host equipment manufacturer’s compatibility list. Store and operate the module within the temperature and humidity ranges specified by the host device to maintain performance and the quoted MTBF.
