Applications
Telecommunications equipment in high voltage areas can be at risk due to Ground Potential Rise (GPR). A
copper network or phone cable referenced to a remote ground can become a path for high voltages
during a ground fault. Placement of an all-dielectric fiber optic cable and locating the CO ADSL fiber card
at either the 300 Volt Point (as determined by a GPR Engineering study) or at the nearest/safest telco
service drop completely eliminates the presence of a copper cable into a high voltage environment. This
design dramatically increases the overall safety of personnel and equipment involved.
The RLH ADSL system provides long distance service (up to 9.6km/6mi.) without any additional
equipment. Utilizing fiber for ADSL transmission has many advantages over copper wire. Fiber optic
cabling is immune to EMI/RF interference, ground loops, and high voltage surges from lightning or ground
faults, and is ideally suited for use in electrically noisy environments such as near large power sources,
electrical motors, and radio communications equipment.

Setting the Optical Gain
DIP switch positions 3 and 4 are used for setting the gain depending on the type of circuit the ADSL
system is connected to.
The factory default setting is OFF for positions 3 and 4, corresponding to 0dB gain, and will function
normally in most installations. The switch settings will not require adjustment unless the ADSL modem on
the SUB side fails to communicate properly with the signal from the fiber link card.
Before adjusting the gain, verify all copper and fiber connections. Refer to the LED status section to verify
correct fiber, power and ADSL operation.
To change the gain:
1. Estimate the effective maximum copper cable length from the CO or nearest repeater to the ADSL CO card.
2. Find the recommended CO and SUB gain settings using the gain charts.
3. Set switch positions 3 and 4 accordingly, using the switch settings table.
Check the ADSL modem for communication status after setting the switches. More than one setting may
be tried before finding the optimum gain setting. Using an incorrect gain setting will not harm the system,
but may prevent the ADSL modem from communicating properly with the fiber card.
Determining Effective Maximum Copper Cable Length
Estimate the maximum length of copper cable in feet, between the Central Office (or the nearest repeater)
and the ADSL CO Fiber Card. For best results, chose the gain setting where the estimated length falls in
the middle of the matching color bar.
