ADDITIONAL FEATURES |
- Link Fault Pass-Through (LFP):
LFP function only takes effect as S1-Bit4 is enabled. Disable S1-Bit4 will turn this media converter into a general one. The LFP function works only when both two converters own this capability in pairs. Furthermore, both LFP converters should be supplied only by the same manufacturer/vendor. The connection coming from LFP converters with odd models or non-LFP converters will cease the LFP function. For example:
- USB Self-powered:
With the optional USB cable (sold separately), power can be drawn directly from your notebook's or desktop's USB port without using an external power adapter.
