Abstract:
1. A method for optical communication, the method comprising: reducing dispersion loss along an electrical transmit path of a transmitter and an optical transmit path coupled to said transmitter via pre-emphasis; improving signal quality along said electrical transmit path of said transmitter and said optical transmit path coupled to said transmitter by equalizing signals received via an electrical receive path of a receiver communicatively coupled to said transmitter; determining said dispersion loss along said electrical transmit path of said transmitter; determining dispersion loss along said electrical receive path of said receiver; and if said dispersion loss along said electrical transmit path of said transmitter is similar to said dispersion loss along said electrical receive oath of said receiver, looping back said electrical transmit oath of said transmitter through an optical module coupled to said electrical transmit path back to a host Serializer-Deserializer (SerDes).
