standards.

 

 

Note: Between the transmit and receive ends of the cable, at least 5db of attenuation is required for a reliable connection. This is equivalent to 20Km of the fiber-optic cable. For distances less than 20Km, you must add attenuators to bring the total attenuation to at least 5db. Most cable vendors carry attenuators.
