Product Overview
6GK5991-2AB00-8AA0 adds two optical Fast Ethernet connections to compatible modular SCALANCE equipment using the MM991-2 BFOC media module.
The module uses multimode glass fiber and fixed BFOC optical connections, with a link reach of up to 5 km when the specified fiber properties and loss budget are met.
Key Functions
Fixed optical connectivity
Two BFOC ports provide 100BASE-FX connections without a separate SFP selection.
Multimode network extension
Both 50/125 µm and 62.5/125 µm multimode glass fiber are supported within the specified link budget.
Host-integrated power
The SCALANCE device supplies the module, and module fusing and signaling contacts are provided by the host equipment.

Frequently Asked Questions
Can I plug single-mode fiber into 6GK5991-2AB00-8AA0?
The BFOC version is designed for 50/125 µm or 62.5/125 µm multimode glass fiber.
How far can I run an optical link from 6GK5991-2AB00-8AA0?
A link can reach 5 km when the specified fiber attenuation, bandwidth and insertion-loss limits are met.
Do I need to buy SFP transceivers for 6GK5991-2AB00-8AA0?
The module has fixed BFOC optical ports rather than SFP slots.
Can I supply 6GK5991-2AB00-8AA0 from a separate 24 V source?
Power must come from the SCALANCE host device and no other power supply is permitted.
Can I use 6GK5991-2AB00-8AA0 in a SCALANCE S627-2M?
The BFOC media module is listed as a supported option for the SCALANCE S627-2M.
Can I use 6GK5991-2AB00-8AA0 for a Gigabit Ethernet optical connection?
The two optical ports operate at 100 Mbit/s using 100BASE-FX.
Does 6GK5991-2AB00-8AA0 provide its own fault relay contact?
The media module has no signaling contact of its own because signaling contacts are provided by the SCALANCE device.
