Cubro's MTP/MPO TAPs are passive fibre breakout TAPs that make an identical copy of your network's data, allowing your monitoring tools to see every bit, byte and packet. The small form of the TAPs allows to combine up to three different Slimline (different splitting ratio, or different connectors) TAPs in one RU.
The challenge of tapping a 40 Gbit link or a 100 Gbit link based on a QSFP is that the QSFP is defined as a quad channel interface (Q = quad), thus the link is actually 4 x 10 Gbit or 4 x 25Gbit respectively. These 4 x 10 or 4 x 25 Gbit links are in a type of trunk where the Ethernet frame/ packet is being divided into four trunks sent in parallel over each of the four fibre links.
The reassembly of the divided frames/packets is handled by a special Layer 1 protocol at the receiving end. The TAP is connected inline with the 8-fibre MTP link. The MTP/ MPO monitor ports feed a copy of the traffic on the link to a set of QSFP receivers on a Cubro Network Packet Broker. The features of the Cubro Packetmaster and Sessionmaster Network Packet Brokers allow the traffic to be reassembled and separated down to 10G or 1G via traffic filters.
