Installation Instructions

Installation Instructions

The Pure Digital Fiberlink® 3150 Series of fiber optic transmission systems are ready for

immediate use and do not require any special tools or equipment. However, an Optical

Power Meter, such as the Fiberlink® 6615, can be useful in determining optical loss budgets

during your systems design and maintenance.

The following instructions describe the typical installation procedure:

1)

2)

3)

4)

5)

6)

Connect the video source to the video input BNC connector on the transmitter unit.

Connect the video output cable to one of the two video output BNC connectors on

the receiver unit.

Terminate any unused BNC output connector at 75 Ohms.

Connect the fiber optic cable to the transmitter and receiver units.

Connect the Universal Power Supply to the transmitter and receiver units.

For box versions using DC power, please refer to figure 1.

When power is applied, the green POWER LED should illuminate, indicating the

presence of operating power. The HD/SD RATE LED will give an indication as described

in the Indicator LED’s and Alarm Circuitry section of this manual.

7)

The system should now be operational.

Note: The Rack Card version has an additional red LED for indicating the presence of an alarm

condition (loss of signal). Refer to Indicator LED’s and Alarm Circuitry sections of this manual.

The transmitting element in the Pure Digital Fiberlink® 3150

transmitter unit contains a solid state Laser Diode located

in the optical connector. This device emits invisible infrared

electromagnetic radiation which can be harmful to human

eyes. The radiation from this optical connector, if viewed at

close range with no fiber optic cable connected to the opti-

cal connector, may be sufficient intensity to cause instanta-

neous damage to the retina of the eye. Direct viewing of this

radiation should be avoided at all times!

Operating Pointers | Troubleshooting

Operating Pointers

The 3150 Series is available in versions that operate with 62.5u and 50u multimode (MM)

and single mode (SM) optical fibers. Be certain that the correct size fiber is being used for

this particular transmitter/receiver combination.

Also, remember to check attenuation of the fiber optic cable. The system will only operate

properly if these specifications fall within the range of the system’s loss budget.

Troubleshooting

Multimode fiber optic cable contains an optical fiber with a light carrying “core” that is

only .0025 inches (62.5 microns) in diameter. Single mode fiber optic cable has an even

smaller “core,” only .00032 to .0004 inches (8-10 microns). This is smaller than a human hair!

Therefore, any minute particles of dirt or dust can easily block the fiber from accepting or

radiating light. To prevent this from happening, always use the provided dust caps when

ever optical connectors are exposed to air. It is also a good idea to gently clean the tip of an

optical connector with a lint-free cloth moistened with alcohol whenever dust is suspected.

The status of the LEDs should provide the first clue as to the origin of any operational

failure. If these are off, it usually means that the fiber is broken or has too much attenuation.

Next, be certain that the input and output signal connections are correct.

An optical power meter, such as the Fiberlink® 6615, a visible light source, such as the

Fiberlink® 6610, and a Three Wavelength Light Source, such as the Fiberlink® 6620, can

greatly assist and expedite troubleshooting of fiber optic transmission systems and are

recommended tools all installers should have available.

Finally, although multimode and single mode devices may look the same, they will not

operate properly together. Using the wrong device or fiber can easily add more attenuation

than specified, resulting in poor overall performance. It should be noted that some of our

fiber optic products support both single mode and multimode fiber in the same unit.

If, after reviewing the above possibilities, the system is still not operating, please contact

the Customer Service Department for further assistance. If you suspect your problem is

caused by the optics or the fiber optic cable, and you have an optical power meter, please

take the appropriate measurements prior to contacting support.
