Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical fiber communication, more particularly to a prefabricated end butterfly cable coupler. BACKGROUND

[0002] In the optical fiber communication system, the prefabricated end butterfly cable coupler and the LC duplex coupler play an indispensable role. The prefabricated end butterfly cable coupler belongs to a passive optical device. Through a specific designed optical structure, it can distribute, combine or separate optical signals. According to the demand, the input optical signal can be distributed to different output ports. It is one of the key components to build an optical fiber network. The LC duplex coupler, also known as duplex LC adapter or duplex LC connector, is a key connection device in the optical fiber communication system. It has two pairs of LC ports and a precise alignment mechanism inside, which can ensure the precise alignment of the optical fiber end face, thereby reducing signal loss and improving network stability and transmission efficiency. With the characteristics of connecting and coupling two optical fiber jumpers at the same time, the LC duplex coupler can realize bidirectional data transmission. Compared with simplex, it greatly improves the network efficiency and capacity.

[0003] However, the connection interface of the traditional coupler is usually sealed by a cap when the connector is not connected. The cap can effectively block dust, water vapor and other pollutants from entering the connection port, prevent the optical fiber end face from being scratched by dust particles, and prevent water vapor from causing optical fiber oxidation and corrosion, thereby reducing signal loss and transmission failure caused by pollution. However, since the cap is usually an independent component, when the connector needs to be connected, the cap needs to be removed. If the connector is not connected or is temporarily placed during the operation process, the connection port is directly exposed, and the cap cannot be found in time to protect the connection port. The lens used for optical signal connection inside the coupler is easily polluted by dust, which affects the quality of subsequent optical signal transmission and increases the risk of loss.
