Telethon 3G

User Guide

Area A – SDI/DATA IN

Fig. 3-3: Four SDI/DATA In BNC Connectors

The Telethon 3G has four SDI/DATA In BNC Connectors. All four inputs operate identically
and are multiplexed for transmission on the fiber output of the unit for demultiplexing to
the four SDI outputs on the receiving unit.

The SDI/DATA connections can carry a variety of Baseband and Data type signals (see

Fiber

Cable Overview

on page 3).

Each input has an LED monitor that indicates the following:

Green: SDI signal is present

Unlit : nothing is connected

Area B – SDI/DATA OUT

Fig. 3-4: Four Fiber SDI/DATA Output BNCConnectors

The Telethon 3G has four SDI/DATA Output BNC Connectors. All four Outputs operate
identically and are multiplexed for transmission on the fiber output of the unit.

Each output has an LED monitor that indicates the following:

Green: the Telethon 3G is receiving a signal for the indicated channel over the

Multiplexed Fiber Optic Cable and SDI signal is present

Alternating between Red and Green: a Fiber Optic connection is detected for the

indicated channel, but no SDI is present.

Red: no optical connection is detected or the active optical signal has fallen below

-22 dBm

See

Area C– Fiber SDI/Data In

on page 12 for more information on understanding dBm

measurements.
