Metal module with precision machined base. On top, there are 3 exposed layers of thin pc board with a total of 17 connectors along all 4 sides of the module. All but one of the connectors have 8 pairs of connections with ground plains between the pairs. There are 8 cable retainer brackets located near the pc connectors. In the center is a large oblong octagonal cap held down by one long and two short diagonal retainer brackets. The base and brackets are all gold plated. There are 4 pairs of coax cables coming from the back of the module. A small green allen (hex) wrench is included with the packaging. It appears to fit the retaining bracket hardware.
