The Fiber Input Optical Power Meter serves two functions.

• The dBm scale indicates the relative strength of any Fiber Optic signal connected to the

Terrapin FTR-D6 unit. The meter covers a range of 0 dBM to -20dBm in 5 dBm
increments. The strongest signal is 0 dBm. The Terrapin FTR-D6 is designed to work
down to a signal strength of -20 dBm.

If these indicators fluctuate during operation, the system will continue to work.
However, if the signal strengthfalls below -20dBm, the Terrapin FTR-D6 may not
continue to pass the Fiber Optic signal.

• The Coax In indicator is a simple On/Off indication that an SDI signal has been

connected to the BNC Input of the Terrapin FTR-D6.
