Optical delay compensation in optical modules

Abstract: an optical module includes a transmitter assembly; a receiver assembly; and circuitry connected to the transmitter assembly and the receiver assembly, wherein the circuitry includes one or more delay elements each configured to add a respective configured amount of delay in one or more of a transmit direction and a receive direction within the optical module. the optical module includes (1) a transmit direction from a host device through the circuitry and the transmitter assembly, and (2) a receive direction to the host device from the receiver assembly and through the circuitry. the one or more delay elements can be configured to introduce a delay in one or both directions to minimize the delay uncertainty associated with the optical module as well as the delay uncertainty on a given link (connection formed between two optical modules).
