1.0 Introduction
A highly reliable managed Ethernet switch is required for use in subsea control networks to provide both copper
and optical links for 10/100/1000 Mbps communications using standard open protocols.
Focal’s Model 922-MES board is a layer 2 managed Ethernet switch (MES) with ten ports capable of
10/100/1000 Mbps link speeds. Two of these ports can be equipped with small form factor (SFP) transceivers
that support Fast (100Base-FX) and Gigabit Ethernet (1000Base-X).
The MES provides a configurable managed switch for use in subsea distribution units or Subsea Electronics
Modules (SEMs). Interchangeable fiber optic transceivers allow for port configuration as low-power optical links
to tie-ins and other subsea nodes or as high-power optical links to the surface via long optical umbilical cables.
Complete redundancy can be achieved using multiple cards within a distribution unit or SEM. Redundancy
protocols supported by the MES include MRP (Media Redundancy Protocol) and RSTP (Rapid Spanning Tree
Protocol).
Advanced diagnostics provide real time health monitoring of the system and include optical SFP information,
temperature, voltage, current, humidity, Ethernet link status, and Ethernet switch configuration. The MES
provides diagnostics access via Telnet and Modbus TCP.
Focal’s subsea qualified fiber-optic SFP transceivers are recommended for use with this board. Options available
include bidirectional transceivers and CWDM transceivers with support for 50 km, 100 km and up to 200 km
range.
Figure 1-1: Model 922-MES
The following features and processes are used to ensure reliability and increase product life:
Conductive cooling and detailed thermal analysis
Advanced diagnostics and health monitoring via Modbus TCP
Use of industrial temperature range electronic components
No fuses, electrolytic or tantalum capacitors
Environmental stress screening
Full qualification testing per API 17F / ISO 13628-6
Traceable components
Use of field-proven electrical and optical components
Design for vibration, shock and EMC

3.0 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.

Connection types shown as “User-External” (CU1-8 and SFP1-2) can be changed by the user as required to
accommodate system-specific requirements. The user must ensure that any switch configuration changes are
valid BEFORE saving it in EEPROM and that communications through all ports is as expected after
configuration.
