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. Table 1 lists the cable specifications. Refer to the OptEnet SFP Transceiver Specifications listed in Related Publications, for optical specifications.

Table 1. Cable Specifications

NETWORK	DATA RATE	MEDIA	LENGTH
10BaseT	10 Mb/s	UTP Cat 3, 4, or 5 (2-pair)	328 feet (100 m)

100BaseTX	100 Mb/s	UTP Cat 5 (2-pair)	328 feet (100 m)

1000BaseT	Gigabit	UTP Cat 5e (4-pair)	328 feet (100 m)

UTP = Unshielded Twisted Pair

Note: The maximum cable length is the cable length that the signal can travel without suffering from attenuation (degradation).

1.1Front 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.
