s. The system supports high bandwidth demands from applications like IPTV, Internet Video, HD programming, and mobile video by increasing the speeds over existing fiber. Typically, increasing the speeds from 10G to 40G to 100G entails trade-offs such as shortening the distance of each network segment or increasing

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).
