What sort of frame forward mechanism do EtherWAN media converters support?

Answer:

1. Store-and-Forward
   The entire frame is received and stored in memory in order to check whether it's error-free before any forwarding takes place. The frame will be discarded if the Cyclic Redundancy Check (CRC) and frame length are considered as invalid.
2. Cut-Through
   As soon as the media converter identifies the destination MAC address of a frame, it starts forwarding the frame before the entire frame is received. Any corrupted frames will also be forwarded.
3. Pass-Through
   Pass-Through simply converts a copper signal into a fiber signal without any error detection; therefore, it has the lowest transmission latency compared with the above three frame forward mechanisms. However, any corrupted frames will also be forwarded.
