1.0 Product Description
Meridian’s product series MT/MR-1HD-x and MT/MR-1HG-x are fiber optic modems that
transmit or receive one channel of real-time, uncompressed video HD-SDI for series
MT/MR-1HD and 3G-SDI for MT/MR-1HG series. This product supports one channel of
SMPTE 292M, 310M, 259M, 344M and 424M compliant digital video data rates, over one
optical fiber using digital transmission technologies. This system is available for use with
multimode or single-mode fibers and with CWDM lasers. System features Automatic Gain
Control - no adjustments are required for different lengths of cables
Both ST and FC optical connectors are supported and includes dust cover with chain. An ST
optical interface is available for both multimode and single-mode fiber applications wile the
FC optical interface is available only for single-mode products.
Optional conformal coating provides an additional level of protection from environments
with high moisture and humidity.
Meridian also offers product series MT/MR-1HD-xK and MT/MR-1HG-xK. This module
kit includes both the miniature transmitter and receiver modules and a pair of universal
power supplies all housed in a handy, rugged carrying case.
2.0 Installation
The package includes modules and power supplies.
This product is powered by WP-5 power supply (100-240VAC) and will accept 5VDC
power. A plug-in power connector is located on the side of the module see Figure 4.1
To install the Module, it is necessary to allow enough space to accommodate the bend radius
of the optical cable connected to it. The transmitter and receiver may be connected directly
to 75-Ohm cameras and monitors, or it may require BNC terminated coaxial cables to input
and output the video signal, see Figure 4.1. Maximum transmitting distance is up to 60 Km.

4.1 Operation LED Status Indicators
The front panel diagram is shown Figure 4.1 there are a number of indicator lights that
provide visual operational status of the modules and link. The receiver module has an LED
received power meter. These LEDs will light when the appropriate amount of optical input
power is detected. There are four LED that monitor and display the input power range 0 to 20dBm. The function of these LED indicators is as follows:
PWR
- Green (normal) - when power is applied to the module

6.0 CWDM Option
These modules are also available with a CWDM option. The MT unit will transmit on one
unique CWDM wavelength and receive on the complementary wavelength. The table below
shows these various wavelength combinations for this particular unit.
Please consult the part number for the transmitter unit to properly identify the wavelength
for your specific module. Matching part number for receiver will be MR-1HD(HG)-3

Wavelength Configuration
When using in a system with a CWDM multiplexer/demultiplexer, it is essential that the
specific wavelengths to and from these units be connected to the corresponding input/output
wavelengths on the CWDM mux/demux units. Otherwise, the individual wavelengths will
not pass through the CWMD mux/demux device.
When using higher power CWDM lasers, an external attenuator of 3dB minimum is required
when performing short distance testing to eliminate optical overload at the Rx unit.

For proper operation, it is necessary to match the transmitter (MT) with the associated
receiver module (MR).
6.0 Troubleshooting
Below is a listing of several problems that may arise during the installation & operation of
the modules. If you are having difficulty installing or operating the modules please refer to
this list below.
Problem:
Action:
Power LED does not light when power to the module is applied
Check power supply to ensure that it is plugged in. If symptom continues,
move module to another power location, if available.
Problem:
Action:
No video at output of module
Check to ensure that the monitor is ON and the video cable is connected to the
correct video port on the Rx module. Check to ensure that video input to the
channels is working and that you have the associated receive channel is being
monitored. With an optical power meter, verify that the wavelength for the
suspect optical channel is working properly at the input to the receiver (MR unit).
Problem: Tx signal light off
Action:
Check SDI input signal
Problem: Tx Laser light off
Action:
Optical module is defective, return to factory for repair.
Problem: Rx Level off
Action:
Received optical signal absent or low. Check fiber connection and optical
power at receiver.
If the problem still persists after reviewing the above items, please contact Meridian
technical support (516-285-1000)
