1 PRODUCT DESCRIPTION
The OptEnet 10/100 or 1000 Mb/s Media Converter with
Small Form-factor Pluggable (
SFP)
module is one of a family of modules that can be plugged into a OptEnet Media Converter
chassis. The module is designed to accept SFP transceivers with optical connectors. This
provides a number of optical signal choices. The module converts optical signals to electrical
signals. The module also performs the reverse function, converting electrical signals to optical
signals. A block diagram of the basic converter assembly is shown in Figure 1. Each module has
three connections fiber input, fiber output, and RJ45 Ethernet.

The OptEnet 10/100 Mb/s Media Converter module supports 10BaseT and 100BaseTX. The 1000
Mb/s Media Converter module supports 1000BaseT data rates with UTP cable.

1.1 Front Panel
Each module has three LEDs, a module power LED and two Link LEDs. Under normal
operation the module PWR LED is green. Front panel indicators and controls are defined in
Table 2. A module is shown in Figure 2.
