All the ports on the tap aggregation switch support both transmit and receive, while the optical splitter sends two unidirectional streams. These are connected to the RX side of two ports. The percentage diverted can vary from 10% to 50%. Fiber optic patch panels: Organizing fiber connections and splices. Fiber optic splitters: Passive optical splitters separate the fibers to distribute signals to. I've used passive TAPs in the past, which is just basically a 'splitter' that gives you a MON port, basically hardware level port mirror. So it's simple, you pass 50Gbps of traffic through the passive splitter, you get 50Gbps out in a monitor port. Leveraging mainstream Ethernet protocols, the Xingmai PEN solution uses optical fibers to implement passive data transmission without the need of any ELV room.
