Introduction

Congratulations on purchasing a quality UNICOM product. 

Unicom’s 

VELOCITY Series

represents the newest, most advanced

generation of signal conversion technology. 

This conver ter is designed to expand your network through a fiber optic
connection extending a fiber link up to 60 km (Single mode in full duplex
mode).

The 10/100TX/100FX Conver ters offer the most popular fiber cabling
connectors: SC and ST formats in Multi-mode and SC in Single Mode.
The UTP por t suppor ts the Auto MDI/MDIX function and there are 4 DIP
switches to set the operation mode for the UTP, Fiber por ts and Link
Loss For warding function. These conver ters can be used in Unicom’s 10
bay media chassis or as stand-alone components.

Key Features

Complies with IEEE 802.3, 802.3u, 802.3x standards.

Conver ts between UTP cabling and Fiber Optic cabling.

One RJ-45 connector, Auto-MDI/MDIX for UTP por t.

Suppor ts 10/100 Mbps Auto-negotiation for UTP por t.

Fiber cabling connectivity up to 60Km.

Uses store-and-for ward switching to separate collision domains.

One fiber connector (SC/Single Mode, SC or ST/Multi-Mode) for
100Base-FX.

Prevents packet loss by suppor ting back-pressure & flow control.

Four DIP-switches for operation mode setup and Link-Loss
For warding function.

Per por t LEDs for diagnosis and maintenance

External DC power adapter, 5V/2.5A

Can be mounted in chassis or used as stand-alone.
