Abstract

The invention provides an optical module. The optical module comprises a transmitting end, wherein the transmitting end comprises a laser, an optical splitter, a modulator and a light combiner; the optical splitter is arranged in an output light path of the laser and is used for splitting light output by the laser into a first light beam and a second light beam; the modulator is arranged in a transmission light path of the first light beam and is used for modulating the first light beam according to a received first electric signal; and the light combiner is arranged in a transmission light path of the second light beam and is used for combining the second light beam and the modulated first light beam and outputting the combined light. By adopting the optical module provided by the invention, the problem that the system power consumption is increased due to the fact that a modulator has relatively large on-chip loss in a traditional intensity modulation direct detection technology is solved.

Description

technical field [0001] The present application relates to the technical field of optical signal intensity modulation direct detection, and in particular to an optical module. Background technique [0002] The data center is composed of thousands of servers interconnected, and the connection distance is from a few meters (server to switch) to no more than 2 kilometers (switch to switch), and its connection rate is continuously increasing. The interface bandwidth of switches is steadily increasing according to Moore's Law, and since Gigabit Ethernet, optical communication technology has been widely used in the internal interconnection of data centers. [0003] Currently, the input / output (I / O) interface rate of the switch can reach 100G, and the modulation and demodulation method adopted is the traditional intensity-modulation direct-detection (IMDD), in which The pulse-amplitude modulation (PAM) electrical signal (PAM2) of the first stage is loaded onto the light through the...
