Anti-crosstalk coaxial optical transceiver integrated device

The invention discloses an anti-crosstalk coaxial optical transceiver integrated device, and particularly discloses a single-TO CAN coaxial optical transceiver integrated device applied to the field of optical communication. The device is composed of an TO tube seat with a groove, a WDM filter structure playing a role of isolating electric and optical signal crosstalk, a tube cap with a ball lens, and elements such as an LD, a PD, a TIA, a capacitor and a resistor. Emitted light by the LD is reflected by the WDM filter placed on the same plane as the LD and reaches the lens, the light is focused by the lens and coupled to an optical fiber; a receiving optical signal from the same optical fiber is focused by the lens, then passes through the WDM filter and a light transmission hole playing a role of shielding, and reaches a PD light receiving surface located in the TO tube seat groove subjected to shielding protection. The special structure of the invention uses the minimal number of elements and effectively solves electric and optical crosstalk between transmitting and receiving in tiny small space. Compared with a currently-used BOSA, the material cost is reduced, the production efficiency can be greatly improved, and the miniaturization requirements of the product can be realized.
