SFP transceiver module BlueOptics B243-BO 1250 Mbit/s Fiber optic

The BlueOptics B243-BO 1250 Mbit/s fiber optic SFP transceiver module provides a compact, metal-housed solution for single-port fiber connections in network equipment. Designed for use in SFP-compatible switches, routers and media converters, this module supports a maximum data transfer rate of 1250 Mbit/s and operates from a 3.3 V supply. With a lightweight silver metal enclosure, it offers standard small-form-factor connectivity for point-to-point optical links and short to moderate distance fiber runs.

Advantages

The module’s metal housing ensures mechanical robustness and thermal dissipation while maintaining a slim SFP form factor compatible with standard cages. Support for a 1250 Mbit/s data rate makes it suitable for Fast Ethernet and legacy Gigabit over certain link configurations. Low weight and a 3.3 V operating voltage enable straightforward integration into existing network equipment without additional power adaptations. The silver finish and standardized interface simplify identification and interchangeability in mixed-vendor environments.

Suitable for

• Upgrading SFP ports on switches and routers to fiber connections
• Connecting media converters or optical links in campus and branch networks
• Replacing or stocking spare SFP transceivers for maintenance

Key specifications

• Interface type: SFP small form-factor pluggable
• Maximum data transfer rate: 1250 Mbit/s
• Operating voltage: 3.3 V
• Housing material and color: metal, silver
• Weight: 20 g

How to use

Ensure the host device supports SFP transceivers and that firmware or vendor compatibility requirements are met before installation. Power down the port or follow hot-swap procedures recommended by the equipment manufacturer, then insert the BlueOptics B243-BO into the SFP cage until it clicks into place. Connect the appropriate fiber patch cable to the transceiver’s optical interface, verify link activity through the host device’s indicators or management interface, and configure link speed and duplex if required by the network. Follow safety procedures for handling optical fiber to avoid exposure to laser light.

Usage recommendations

Store and handle the transceiver in a dust-free environment and use protective caps on the optical ports when not connected. For reliable operation, use compatible fiber patch cords and verify link parameters after installation. Replace the module if physical damage or degraded link performance is observed.
