INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RTM-1600P multimode mini video
transmitter. Please take a few minutes to read these installation instructions in order to
obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The RTM-1600P operates as half of a transmitter / receiver pair for the transmission of
baseband NTSC, PAL, RS170, or RS343 video signals and return control for Panasonic
‘up-the-coax’ systems. It is designed to operate with the MRM-1600P or RRM-1600P
video receiver over a single multimode fiber optic cable.
The RTM-1600P converts a single video input into a FM modulated optical output using
a 1300 nm wavelength source. The RTM-1600P also converts an optical control signal
returning on the same fiber into an electronic camera control signal using an 850 nm
wavelength detector. This electronic camera control signal is sent back to the camera on
the same coax cable that the video originated on. The M1600P Series product is
designed to operate over an optical loss budget range of 0 to 12 dB. Panasonic allows a
maximum transmission distance of up to 1.6 km (1 mile) for their ‘up-the-coax’ protocol.
The RTM-1600P operates on 50 um or 62.5 um multimode fiber. Refer to the data
sheets for detailed performance specifications.
This unit is designed for rack mounting in any of the three American Fibertek subracks
available. The subrack model numbers are SR-20/1, SR-20R/1, and SR-20/2. Slide in
rack mounting and LED indicators provide for easy installation and monitoring of video
and power.
The RTM-1600P is designed for rack mounting only. For a modular stand alone version
please see the MTM-1600P.
INSTALLATION
THE INSTALLATION OF THIS UNIT SHOULD BE MADE BY A QUALIFIED SERVICE
PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.
The unit slides into any open slot in the SR-20 subrack. Use a small screwdriver to push
and lock the two ¼ turn fasteners into place.
POWER SOURCE
Power to the unit is supplied by the subrack. Please refer to the SR-20 and PSR
instructions for further details.
POWER CONNECTION
Power is supplied to the unit via a four finger backplane connector. The RTM-1600P can
be inserted into the subrack or removed from the subrack with power applied to the
backplane.
INPUT / OUTPUT CONNECTIONS
The fiber optic connection is made via a ST connector located on the back of the unit.
Be sure to allow sufficient room for the required minimum bend radius of the fiber used.

The video input connection is made via a BNC connector on the back of the unit. The
video input should be connected to an appropriate 75Ω baseband VD-2 protocol video
source. For optimum performance the video cable should be the shortest length of coax
practical.
RTM-1600P STATUS INDICATORS
The RTM-1600P transmitter provides the following LED status indicators to aid in
installation and troubleshooting:
VLI
A bi-color LED indicator is provided for the video input to the RTM-1600P. DC power and
video status associated with this LED is summarized below.

OLI
A bi-color LED indicator monitors the optical input power of the data signal that is being
received at the RTM-1600P from the MRM-1600P or the RRM-1600P. DC power and
optical input status associated with this LED are summarized below.
Optical Level Indicator DC Power Status Optical Status
Green On Proper Optical Input Power Present
