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