Area C– Fiber SDI/Data In
Fig. 3-5: Fiber SDI/DATA Input ST Connectors
The Telethon 3G has four Fiber Channel SDI/DATA Input ST Connectors. All four inputs
operate identically and are multiplexed for transmission on the fiber output of the unit. The
four Fiber signals are demultiplexed in the receiving unit and appear on the four ST
outputs.
The Fiber connections can carry a digital optical signal of not more than 3Gb/s.
Each input has an LED monitor that indicates the following:
• Green: fiber optic connection is present with active SDI signal
• Red: no optical connection is detected or the active optical signal has fallen below -22
dBm
• Alternating between Red and Green: a fiber optic connection is detected for the
indicated channel, but no SDI is present.
Area D– Fiber SDI/Data Out
Fig. 3-6: 4 SDI/DATA Output STConnectors
The Telethon 3G has four Fiber Channel SDI/DATA Output ST Connectors. All four Outputs
operate identically and are demultiplexed from the signals received from the sending unit.
The Fiber connections can carry a digital optical signal of not more than 3Gb/s.
The Fiber outputs do not have associated LED indicators.
