The diminished sale value of a title branded vehicle reduces the profitability of switching the registration and VIN from an accident vehicle to that of a stolen vehicle of the same make and model/year, in an attempt to register it as a rebuilt car and sell it. A consumer-protection warning.
The minimum length for the optical fiber on a cable is: L(min) = A(min) / a= 6.5dB/ 0.22dB/km = 29.5km. The maximum length for the optical fiber on a cable is: L(max) = A(max) / a = 21.5dB/ 0.22dB/km = 97.72km. where, a = attenuation for the optical cable (dB/km). On the basis of this calculation, the maximum hop distance for the OC48 LR 1550 card is between 29.5km and 97.72km. With this procedure as a basis, you can now calculate all others spans.
Modern fiber optic cables can carry a signal quite a distance -- perhaps 60 miles (100 km). On a long distance line, there is an equipment hut every 40 to 60 miles. The hut contains equipment that picks up and retransmits the signal down the next segment at full strength. See the next page for more information.
