A novel single fiber four-transmission four-reception BIDI optical device and packaging process thereof

Abstract

The application discloses a novel single-fiber four-transmitting and four-receiving BIDI optical device and a packaging process thereof, and the single-fiber four-transmitting and four-receiving BIDI optical device comprises a metal shell, a four-transmitting TOSA, a four-receiving ROSA and a ferrule sleeve assembly which are welded into one body with the metal shell, a first mirror frame and a second mirror frame are arranged in the metal shell, 8-degree filter, 37-degree filter and LENS are arranged on the first mirror frame, and 45-degree filter is arranged on the second mirror frame. Compared with the prior art, the application has the positive effect that the application integrates the functions of the four-transmitting TOSA device and the four-receiving ROSA device into one body, four-wave signals are integrated into one optical fiber by using the wavelength division multiplexing function, and the four-transmitting and four-receiving TOSA and the four-transmitting and four-receiving ROSA functions are simultaneously supported. The application can use the existing terminal network equipment, does not need to change the existing network resources, and can replace the user demand according to the service package upgrade on demand, so that the rapid and smooth upgrade of the high-bandwidth service is realized.
