A key advantage of the SFP/SFP+ modules is the straightforward configuration they provide, with four DIP switches to define the default configurations at start-up time between different modes.

‍

MultiGigabit SFP+ Module:

DIP Switch 1:  Master/Slave

DIP Switch 2: 10G/other

DIP Switch 3:  2.5G/5G

DIP Switch 4:  USXGMII on/off

‍

100/1000BASE-T1 SFP Module:

Dip switch 1: Master/Slave

Dip switch 2: 100/1000 Mbit/s

Dip switch 3: Reserved

Dip switch 4: Reserved

‍

The modules also a include the key I2C-to-MDIO gateway feature, which enables advanced Ethernet PHY management by allowing access to the underlying PHY registers via the I2C bus. It also adds a custom implementation to change the DIP switches default status at run-time so system integrator can change dynamically between PHY configurations offered by Technica, overriding default configuration status set in the physical DIP switches, and without needing the register-level complete technical information from the PHY manufacturer*.
