because of the weakening of optical signals as they travel. Prevention of this signal loss would normally require amplifiers or repeaters, or in some cases, installing new and finer-quality fiber. Nortel overcomes this signal loss by using a signal modulation technology called dual-polarization quadrature phase shift keying (DPQPSK).
