SFP transceiver module BlueOptics R9Q43A-BO 1250 Mbit/s 850 nm

The BlueOptics R9Q43A-BO SFP transceiver module is designed for short-range fiber optic connections and supports a maximum data transfer rate of 1250 Mbit/s. Operating at a wavelength of 850 nm, this compact module comes in a durable metal housing, accepts LC fiber connectors and runs on a 3.3 V supply. With a maximum reach of up to 550 m over multimode fiber and a lightweight construction of 20 g, it is suitable for installation in switches, media converters or other SFP-compatible network equipment where reliable high-speed links are required.

Advantages

The module provides a standardized SFP form factor for easy hot-plug installation and a silver metal casing that ensures mechanical protection and thermal dissipation. Its 850 nm wavelength and 1250 Mbit/s capability match common Ethernet and fiber channel interfaces for short-distance links. Low weight and compact dimensions simplify handling and reduce strain on chassis modules during installation.

How to use

Before installation, power down the host device if hot-plugging is not supported by the equipment. Remove any protective dust caps from the LC connector and insert the SFP module into the appropriate SFP slot until it clicks into place. Connect the LC fiber patch cable ensuring correct polarity and secure fiber routing to prevent bending beyond manufacturer-recommended radius. After insertion, power the device or allow the hot-plug to be recognized; verify link status LEDs or management interface for successful link establishment.

Recommendations

Use multimode fiber cable that matches the module's wavelength for optimal distance performance, avoid excessive bending or stress on fiber cables, and keep connector endfaces clean to maintain signal quality. Verify compatibility with the host device’s supported SFP modules and firmware before deployment.
