SFP transceiver module BlueOptics QFX-SFP-1GE-LX 1250 Mbit/s 1310 nm

The BlueOptics QFX-SFP-1GE-LX is a fiber optic SFP transceiver module engineered for reliable single-mode fiber links. It supports a maximum data transfer rate of 1250 Mbit/s and transmits at a wavelength of 1310 nm. The module uses an SFP interface, offering compact hot-pluggable connectivity for switches, routers and media converters that accept SFP form-factor modules.

Advantages

The module provides stable optical transmission for long-distance links on single-mode fiber, combining compact SFP size with a 1310 nm transmitter for lower attenuation over standard single-mode cabling. Its support for a 1250 Mbit/s line rate ensures compatibility with Gigabit Ethernet and related serial optical protocols. The hot-pluggable SFP interface simplifies installation and replacement without powering down equipment, and the standardized physical form factor enables broad interoperability with devices that support industry-standard SFP modules.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect a single-mode fiber patch cable with appropriate connectors to the transceiver’s optical port, ensuring correct transmit/receive orientation. Verify link status on the host device and confirm supported data rate settings. To remove the module, disengage any retention mechanism and pull the transceiver straight out while the device is powered or following the host equipment’s hot-swap guidelines.

Recommendations

Use clean, certified single-mode fiber cables and dust caps when the transceiver is unused. Check compatibility lists of host equipment for SFP module support and follow ESD precautions during handling. For best link performance, verify fiber attenuation and connector cleanliness, and keep spare modules in protective packaging when not installed.
