Patent ID: 7720387

Claim:
In an optical transceiver that includes at least one processor, a persistent memory and a system memory, a method comprising the following: an act of accessing a temperature as measured by a temperature sensor, the temperature being associated with the optical transceiver; an act of calculating appropriate values for a laser bias current and for an operational parameter of a receiver portion of the optical transceiver given the accessed temperature using first and second formulaic relations, wherein the first formulaic relation is a relation between temperature and an appropriate value for a laser bias current, and the second formulaic relation is a relation between temperature and an appropriate value for the operational parameter of a receiver portion of the optical transceiver; and an act of adjusting the laser bias current and the operational parameter according to a result of the act of calculating, wherein adjustment of the laser bias current and the operational parameter, as well as calculation of the appropriate values, is performed without the use of a temperature table, wherein the act of calculating the appropriate values using the first and second formulaic relations is performed without feedback.
