Application notes for SFP modules

The SFP is not sold by Beckhoff as an accessory and is not part of the scope of delivery.

A functional guarantee and compatibility with all SFPs available worldwide cannot be given by Beckhoff. When procuring the SFP individually, the following points must be observed:
- the suitable operating temperature range of the SFP
- no use of 100 Mbit modules, only 1Gbit SFPs are permitted
- no SFP+ modules (SFP+ means >1Gbit)
- Matching light wavelength

In EtherCAT operation, the SFP used must not impair operation (link control, timing).
