SFP transceiver module BlueOptics EX-SFP-1GE-SX 1250 Mbit/s 850 nm

The BlueOptics EX-SFP-1GE-SX is a small form-factor pluggable (SFP) fiber optic transceiver module that supports a maximum data transfer rate of 1250 Mbit/s and operates at an 850 nm wavelength. Designed for use in 1 Gigabit Ethernet links over multimode fiber, this SFP transceiver provides optical connectivity for switches, routers and media converters that support SFP interfaces. The module fits standard SFP ports and delivers reliable short-range optical transmission in enterprise and data center environments.

Advantages

The BlueOptics EX-SFP-1GE-SX combines compact SFP form factor compatibility with 850 nm multimode operation, offering straightforward installation and hot-pluggable convenience. Its support for up to 1250 Mbit/s ensures compatibility with Gigabit Ethernet links while maintaining low power consumption and modest thermal output. The module is suitable for replacing or expanding optical ports on compatible network equipment without requiring configuration changes on the host device.

Suitable for

• Short-distance Gigabit Ethernet connections over multimode fiber (OM1/OM2/OM3 depending on link budget)
• Upgrading switch or router ports to fiber uplinks
• Interconnecting network equipment in data centers, server rooms and campus networks
• Use with media converters and fiber access devices supporting SFP interfaces

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Maximum data transfer rate: 1250 Mbit/s
• Optical wavelength: 850 nm (multimode fiber)
• Transmission distance: typical short-range multimode links (depends on fiber type and link budget)
• Interface: hot-pluggable SFP electrical connector for 1G ports

How to use

Insert the BlueOptics EX-SFP-1GE-SX into an available SFP slot on a compatible switch, router or media converter until it clicks into place. Connect a suitable multimode fiber patch cable (with matching connector type) between the transceiver and the remote optical port. Ensure both ends use compatible multimode fiber types and that link distance falls within the supported range. The host device should automatically detect the module; verify port status and link parameters through the device management interface if necessary.

Usage recommendations

For reliable performance, use multimode fiber and patch cords in good condition, verify connector cleanliness before mating, and choose cable types appropriate for the intended distance (OM1/OM2/OM3). Avoid exposing the module to excessive mechanical stress or temperatures outside the equipment specifications. If interoperability issues occur, consult the equipment vendor documentation for supported SFP transceiver models and any required firmware updates.
