SFP transceiver modul BlueOptics PN54021K-BO 1250 Mbit/s optické vlákno

The BlueOptics PN54021K-BO is an SFP fiber optic transceiver module designed for 1250 Mbit/s data transfer over multimode fiber. Housed in a silver metal enclosure and weighing approximately 20 g, this module follows MSA SFP form-factor standards and offers LC Duplex connectivity for simultaneous transmit and receive channels at 850 nm. It is CE, RoHS and FCC compliant and intended for use in common network hardware that accepts SFP modules.

Advantages

This SFP transceiver provides a compact SFP interface with a 1250 Mbit/s line rate suitable for Gigabit Ethernet applications. The LC Duplex optical connection enables separate transmit and receive paths, and the module’s compliance with industry mechanical and electrical standards ensures broad compatibility. Built-in digital diagnostics (DDM/DOM) support allows real-time monitoring of parameters such as optical power and temperature when the host device supports the feature.

Key specifications

How to use

Insert the SFP module into an empty SFP slot on a compatible switch, router or other network device until it clicks into place. Connect LC Duplex multimode fiber patch cables to the module’s LC ports, taking care to align transmit to receive on the opposite end. Power the host device and verify link and speed status in the device’s management interface. If digital diagnostics are required, enable or query DDM/DOM via the host system to monitor optical power, temperature and supply voltage.

Recommendations

Use quality multimode LC Duplex patch cables and maintain proper bend radius of the fiber to ensure signal integrity; verify that the host device supports 1000Base-SX SFP modules and DDM/DOM if monitoring is required. For reliable operation, keep the module and connectors clean and store unused modules with dust caps.
