SFP transceiver BlueOptics 3CSFP81-BO Fiber optic 155 Mbit/s

The BlueOptics 3CSFP81-BO is an SFP fiber optic transceiver module designed for point-to-point data links and network equipment that accept SFP form-factor modules. With a maximum data transfer rate of 155 Mbit/s and a compact nickel-coloured metal housing, this transceiver provides a standardized interface for fiber connections while remaining lightweight at approximately 20 g. It is compatible with 3Com 3CSFP81 and complies with RoHS, CE, FCC and ISO9001 standards, making it suitable for integration into existing networking infrastructures that require reliable single-channel fiber links.

Advantages

The module offers an industry-standard SFP interface for easy hot-plug installation into compatible switch and router ports. Its modest power and physical footprint suit equipment racks and limited-space installations. Compliance with common regulatory and quality standards ensures interoperability and predictable performance characteristics. The metal housing provides mechanical protection and thermal stability for consistent optical performance.

Suitable for

• Short- to medium-distance fiber optic uplinks and linking between switches
• Replacing or extending legacy 155 Mbit/s fiber connections in existing networks
• Laboratory testing and development setups that require an SFP fiber interface
• Network equipment that requires RoHS/CE/FCC-compliant modules

Key specifications

• Interface type: SFP small form-factor pluggable
• Maximum data transfer rate: 155 Mbit/s
• Housing: metal, nickel-coloured
• Weight: 0.02 kg
• Optical medium: fiber optic (single-channel)
• Standards compliance: RoHS, CE, FCC, ISO9001

How to use

Insert the BlueOptics SFP transceiver into an empty SFP port on compatible network equipment until it seats securely and the device recognises the module. Connect the appropriate fiber patch cable to the transceiver's optical connector, ensuring correct connector type and polarity for the link. Configure the network device if necessary to use the 155 Mbit/s link speed and verify link status through the host device management interface or status LEDs. For removal, power down the port if recommended by the equipment manufacturer, then extract the module by disengaging any retention mechanism and pulling it straight out.

Usage recommendations

Use fiber patch cables and connectors that match the transceiver's optical interface and maintain clean connector end faces to prevent signal loss. Ensure that the host device supports 155 Mbit/s SFP modules and follow the equipment manufacturer's guidance on hot-plugging and ESD precautions.
