Embodiment

[0061] The present invention as figure 2 As shown, it mainly includes an optical fiber array 1 with n (n=1, 2, 3, 4) optical fibers, an optical fiber array 2 with 2n small bending radius optical fibers, and two focusing lenses ( figure 2 503, 506), a film filter ( figure 2 505), three glass tubes ( figure 2 501, 504, 508).

[0062] The optical fiber array 1 includes n (n=1, 2, 3, 4) optical fibers, which are mainly used for transmission after optical fiber demultiplexing;

[0063] The optical fiber array 2 includes 2n small bending radius optical fibers, which are mainly used for step-by-step separation and transmission of signals in the demultiplexing process;

[0064] The focusing lens 503 is mainly used for collimation of the mixed light beam before stepwise separation, and the focusing lens 506 is mainly used for collimation of the separated light beams of four wavelengths (λ1, λ2, λ3, λ4).

[0065] The thin-film filter is mainly used for stepwise separation of lig...

Abstract

The invention discloses an ultra-compact multi-channel wavelength division multiplexer for a 5G optical network, comprising: an optical fiber array with n optical fibers, an optical fiber array with 2n small bending radius optical fibers, two focusing lenses, a thin film filter, and three glass tubes, wherein the two focusing lenses are a first focusing lens and a second focusing lens, respectively; the three glass tubes are a first glass tube, a second glass tube and a third glass tube, respectively; the thin film filter is arranged between the first focusing lens and the second focusing lens, and the three are fixed in the second glass tube; the first focusing lens, the second glass tube, the thin film filter and the second focusing lens are collectively referred to as an intermediate component; the optical fiber array with 2n small bending radius optical fibers is bonded to the intermediate component through the first glass tube, and the optical fiber array with n optical fibers isbonded to the intermediate component through the third glass tube.

Description

technical field [0001] The invention relates to the field of 5G mobile communications, in particular to an ultra-compact wavelength division multiplexer for 5G optical networks. Background technique [0002] The 5G network is an inevitable choice for mobile operators in the future, and the 5G network is characterized by a denser network to achieve high throughput and low latency services. Achieving network densification requires deploying small cells every few hundred meters throughout the radio access network (RAN), or splitting existing macro cell sectors to increase capacity. Whether for small base stations or macro base stations, C-RAN is the enabling architecture for RAN and lays the foundation for 5G. Therefore, C-RAN is a major trend in the wireless industry today. [0003] WDM network systems can perfectly support fast-growing mobile applications such as distributed antenna systems (DAS), small cell base stations and Wi-Fi backhaul and / or C-RAN fronthaul. In order...
