The following figure illustrates an SFP module:
Warning: Class I laser product.
You can use either of the following types of SFP depending on the
cable/fiber type you are using. You can purchase SFPs separately from
the NSG either from Harmonic or other sources. In this case it is strongly
recommended to purchase SFP models qualified by Harmonic:
Note: When using an SFP with a copper cable, enable the Auto
Negotiate and Last in Chain options via the Web client. Cascading is
unavailable and the automatic channel redundancy is activated only
when the alarm SFP not mounted appears. The copper SFP does not
trigger the GbE link down alarm.
