The Preseem 10000 hardware platform is capable of intersecting 10Gbps of traffic via one or more pairs of 10G SFP+ links, copper 1G links or 40G QSFP+ links.
The Preseem 10000B has four 10G (SFP+) ports to enable intersecting up to two 10G links. A single pair of 1G copper ports can also be used to intersect a single 1G link.
The Preseem 10000C adds optical bypass capabilities to the Preseem 10000 platform.
The Preseem 10000E has two 40G (QSFP+) ports which enable intersecting a 40G link.
The Preseem 10000F adds two 40G (QSFP+) ports to the 10000B. This enables intersecting two 10G links and/or one 40G link.
