Abstract: The optical transmission module provided is designed to be simpler, smaller, and faster. It consists of a housing that holds one or more stacked substrates, partially exposed. Inside the housing, there is a light emitter that generates optical signals and an optical functional element that processes the transmission signal for driving the light emitter. Multiple terminals extend from the inside to the outside of the housing on the substrates. The terminals are divided into two groups: the first group connects to electrodes of a high-frequency circuit in the optical functional element, and the second group connects to electrodes of a low-frequency circuit. The length between the upper surfaces of the first group terminals and the high-frequency circuit electrodes is shorter than the length between the upper surfaces of the second group terminals and the low-frequency circuit electrodes, in the direction perpendicular to the substrates' major surface.

Abstract: The objective of the present invention is to quickly and precisely correct the measured value for light reception power to the actual value with few resources, by installing a correction device for a light reception power monitor for signal light in an optical module. The correction device is equipped with a correction table which is referenced when correcting the measured value for the light reception power of signal light, and in this correction table multiple correction values are stored in advance on the basis of the correspondence relationships between multiple reference values and multiple actual values. In the correction table, for segments wherein the change in the actual values with respect to the change in the measured values is small, the interval between the reference values is made smaller and more correction values are stored than for segments wherein the change in the actual values with respect to the change in the measured values is large. When an input value indicating the measured value for the light reception power of the signal light matches a reference value in the correction table, the correction device reads from the correction table the correction value corresponding to the reference value. When an input value does not match a reference value in the correction table, the correction device calculates a correction value in accordance with a prescribed calculation formula on the basis of the input value.

Abstract: Please delete the Abstract of the Disclosure, and replace it with the following: A wavelength variable optical transmitting unit is configured to be able to transmit a first channel setting optical signal including first channel information indicating a channel for the first channel setting optical signal. A wavelength variable optical receiving unit is configured to, when the optical transceiver receives a second channel setting optical signal from another optical transceiver, transfer second channel information contained in the second channel setting optical signal and indicating a channel for the second channel setting optical signal. A control unit is configured to control the wavelength variable optical transmitting unit and the wavelength variable optical receiving unit. The control unit sets, based on the second channel information that the wavelength variable optical receiving unit has transferred, a first channel indicated by the second channel information as a channel through which the wavelength variable optical receiving unit receives an optical signal.
