SFP-transceiver BlueOptics ET4201-SX-BO 1250 Mbit/s glasvezel

The BlueOptics ET4201-SX-BO 1250 Mbit/s Fiber optic SFP transceiver is a compact module for multimode fiber networks. In the SFP form factor it supports optical transmission and reception at 850 nm with LC duplex connection and a maximum data rate of 1250 Mbit/s. The module is compliant with CE, RoHS and FCC directives, weighs approximately 20 g and is designed for use in common network hardware such as switches, routers, storage systems and measurement devices.

Advantages

The transceiver follows MSA-compatible SFP standards, enabling straightforward hot-plug installation and broad hardware compatibility. Its multimode 850 nm transmitter and receiver pair deliver reliable optical links with low electromagnetic interference susceptibility. Built from quality components and tested for compatibility, the module offers long service life and stable performance in standard 1000Base-SX environments.

How to use

Insert the SFP transceiver into an empty SFP slot of a compatible switch, router or other network device while the device is powered on or according to the device manufacturer’s instructions. Connect LC duplex multimode fiber patch cables to the transceiver's LC ports, observing transmit (TX) and receive (RX) orientation. Configure the host device network settings as required for 1000Base-SX operation. If Digital Diagnostics Monitoring (DDM/DOM) is supported by the host hardware, enable and monitor diagnostic parameters such as optical power and temperature through the device management interface.

Recommendations

Use short, high-quality multimode LC duplex patch cords and avoid tight bends in fiber runs to preserve signal integrity. Confirm host compatibility with MSA-compliant SFP modules and enable DDM/DOM monitoring on compatible equipment for proactive maintenance.
