Small Form-factor Pluggable

SFP stands for Small Form-factor Pluggable, which is a type of connection defined by the SFP Multi-Source Agreement (not an official specification or organization). SFPs are small transceiver modules that can be inserted in the SFP carrier ports of any of OPAL-RT’s simulators that support SFP connections.

The following systems from OPAL-RT support SFP connections:

OP7000 with OP7361 carrier (8 SFP)

OP7020 (16 SFP)

OP4500 (4 SFP)

OP5607 (16 SFP)

SFP modules can also be used to convert electronic signals to optical signals, allowing multi-mode fiber optic cables to be used to connect devices together.

The term “High Speed” refers to communication rates of at least 1 Gbps (Gigabit per second); SFP modules used in OPAL -RT’s systems can usually reach 5 Gbps.

There are two main reasons for a user to be interested in using SFP communication with OPAL-RT products:
System expandability: using SFP transceivers, one can exchange data at fast speeds between the FPGAs from two or more OPAL-RT chassis.
Communication with third party systems: the protocols described in the following sections can be implemented in 3rd party FPGA cards, making it possible to exchange data at high speed between OPAL-RT products and 3rd party systems.
