1. The limiting factor is saturation of the receiver by the transmitter. When presented with a signal at a strength

above the saturation point, the receiver cannot distinguish between pulses, though no hardware damage

occurs.

10GBASE-LR-XFP SMF (Single Mode Fiber) 10 km (6.21 mi) 2 m (6.6 ft) LC

10GBASE-ER-XFP SMF (Single Mode Fiber) 40 km (24.85 mi)

2. Links longer than 30 km for the same link power budget are considered engineered links. Attenuation for such

links needs to be less than the minimum

2 m (6.6 ft) with

minimum of 5 dB
