PLANET SFP port 100Base-FX transceiver single-mode 1310nm (MFB-TF20)

The PLANET MFB-TF20 is a high-performance SFP (Small Form-Factor Pluggable) transceiver designed for 100Base-FX Fast Ethernet networks. It operates on single-mode fiber at a wavelength of 1310 nm, supporting data transmission distances up to 20 km. This hot-pluggable module features an LC duplex connector and includes Digital Diagnostic Monitoring (DDM) for real-time performance tracking. Compliant with IEEE 802.3u and SFP MSA standards, it is ideal for extending network reach in enterprise, telecom, and industrial environments.

Advantages

The MFB-TF20 offers reliable long-distance connectivity with low power consumption (max 1W) and commercial-grade operating temperature range (0 to 70°C). Its hot-pluggable design allows for easy installation and replacement without network downtime. DDM support enables proactive network management by monitoring parameters such as temperature, voltage, and optical power levels.
