Abstract

The invention discloses a single-fiber bidirectional transceiving module. The module comprises a laser diode, a photodiode, a first lens and a second lens, wherein a light splitter is arranged between the first lens and the second lens and is plated with a transmission increasing film and a reflection increasing film; the first lens, the second lens, the laser diode and the photodiode are positioned on the same optical axis which is a straight line; and at least one of the first lens and the second lens is an aspherical lens. The invention further discloses a package for the module and a using method for the package. A spherical lens or the aspherical lens is used, so that the size of the optical module in the direction of the laser diode is reduced, and the size of the whole optical device is reduced; by utilizing the characteristic of high coupling efficiency of the aspherical lens, the requirement of high output power is met; and the spherical lens has the function of prolonging a light-gathering focal distance and is matched with the aspherical lens, so that products are coupled and packaged by laser diode (LD) TO components in different packaging modes.

Description

technical field [0001] The invention relates to an optical transceiver module and its packaging, belonging to the field of optical fiber transceivers. Background technique [0002] The most commonly used traditional communication methods are optical fiber communication and twisted pair communication. Among them, optical fiber communication signals have the characteristics of long transmission distance, small distortion, and small interference, while twisted pair communication has the advantages of convenient networking, simple access, and compatible equipment. Good sex and other characteristics. The optical fiber transceiver combines the characteristics of the above two methods, and can convert these two communication methods. The optical transceiver module is a key component of the optical fiber transceiver, which is used for mutual conversion between light and electricity. It determines the quality of the entire transceiver, which determines the communication distance, si...
