Description

technical field

[0001] The invention relates to the technical field of digital optical fiber transmission systems, in particular to a tunable direct-adjustable optical transmission module and a calibration and adjustment method thereof. Background technique

[0002] With the continuous development of optical communication technology, optical transmitting modules and optical receiving modules have been more and more widely used in optical transmission systems, which play the role of electrical / optical and optical / electrical conversion, and their performance is important to optical transmission system indicators. influences. The telecommunication equipment sends the high-speed electrical signal to the optical transmission module after processing, and the optical transmission module modulates the electrical signal to the optical signal output by the laser through the modulator, so that the signal can be transmitted in the optical domain. Medium and long-distance optical transm...
