FAQ
1. Why use BiDi?
A: The BiDi module can carry data in two directions using a single fiber,The module must be used in pairs, and its biggest advantage is doubling the network capacity and saving fiber resources.
2. What are the advantages of BiDi SFP?
A: BIDI is belong single-fiber bidirectional transceiver, only has 1 port, filtering through the filter in the optical transceiver, and finish the emission and reception at the same time.
