Architecture Overview
The Model 922-MES may be configured with optical links for long distance connections from subsea to surface
or long distance optical links (up to 200 km) connecting between subsea nodes. Copper ports support links to
short distance (up to 100 m) sensors and PLCs.
The 922-MES supports:
Two (2) SFP Ethernet ports for 100BASE-FX / 1000BASE-X operation
Eight (8) Copper Ethernet ports for 10BASE-T /100BASE-TX / 1000BASE-T operation
The Ethernet ports and media types available for the MES is shown in the figure below.
Figure 3-1: Model 922-MES Ethernet Ports
The 922-MES PCB has a Eurocard form factor with a 96-pin DIN header at the back for access to eight copper
ports (CU1 to CU8) and power. The two SFP transceiver cages at the front provide access to SFP1 and SFP2
ports.
