Subject: significantly higher implementation penalty gen. Контекст"The high symbol rate will encounter significantly higher implementation penalty with today’s electro-optic technology for the same modulation type. Implementing a 1 Tb/s super-channel using 10 carriers divides both the required electronics performance and the Baud rate on the fiber by a factor of 10, and so 32 GBaud electronics is all that is required. Moreover, because the symbol rate of each carrier is (in this example) the same as a 100G PM-QPSK transponder, the optical performance is more than adequate for most terrestrial long haul and ultra-long haul links." Вопрос: "significantly higher implementation penalty" - ??? Спасибо! |

при нынешнем состоянии оптоэлектронной технологии и при сохранении того же типа модуляции, внедрение более высокой скорости не обойдётся без потерь |
