Optický transceiver modul PLANET MFB-F20

The PLANET MFB-F20 is an SFP fiber optic transceiver module designed for 100 Mbit/s duplex data links over optical fiber. Compliant with the SFP Multisource Agreement (MSA), the module is hot-pluggable and fits SFP MSA–compatible ports for easy installation without interrupting host equipment operation. Using a 1310 nm FP laser diode, this transceiver supports transmission distances up to 2 km on multimode fiber and up to 60 km on single-mode fiber. The MFB-F20 belongs to the MFB-T series intended for industrial Ethernet use, offering reliable performance across a wide operating temperature range (-40°C to 75°C) and resistance to electrically and climatically demanding environments.

Advantages

The MFB-F20 provides standard SFP form factor compatibility and hot-pluggable convenience, enabling quick module swaps and upgrades. Its 1310 nm FP laser supports long-reach connections suitable for both multimode and single-mode fiber links. The device is engineered for wide-temperature industrial environments, ensuring stable operation in harsh electrical and climatic conditions. The metallic housing offers durability and electromagnetic resilience appropriate for network equipment.

How to use

Insert the MFB-F20 transceiver into an SFP MSA–compatible port on the host device while the host remains powered, if supported, to take advantage of hot-pluggable capability. Connect the appropriate single-mode or multimode fiber cable to the transceiver’s optical connector, ensuring correct connector type and polarity. Verify link settings on the host device to match 100Base-FX parameters. Monitor the host equipment’s port status indicators or management interface to confirm a successful link and correct operation.

Recommendations

Use single-mode fiber for links approaching the 60 km range and multimode fiber for shorter distances up to 2 km. Select fiber connectors and patch cables that match the transceiver’s optical interface and maintain proper cable management to avoid bend losses. For installations in extreme climates or electrically noisy locations, follow the host equipment and site grounding guidelines to ensure reliable operation within the specified -40°C to 75°C range.
