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.
Re: RJ45 Maximum Cable Length. In theory, an ethernet cable can be run 100 meters (about 328 feet). However, cables can pick up electrical noise on long runs. Also, some cables are poorly made. The longer the cable, the more important it is for the cable to be properly shielded, and to be a good quality cable.
