Existing Fiber To The Home (FTTH) networks can be roughly classified into two types, Passive Optical Network (PON) and Active Optical Network (AON), according to different devices in the network structure. Among them, PON is more popular in FTTH deployment due to its low cost and high performance.

The traditional PON terminal equipment is of a box-shaped structure, and needs to be hung on a wall or be additionally provided with a weak current box, so that the attractiveness is influenced. In order to make the appearance of the PON terminal device fit the decoration layout of the use scene, panel-type PON terminal devices are gradually emerging. The panel type PON terminal equipment comprises a junction box embedded in a wall body and a panel installed on the junction box, the panel comprises a cover plate and an accommodating part which can be mutually detached, the middle part of the accommodating part is arched towards the back to form a containing pit with an opening at the front, and the containing pit sinks into the junction box when the panel is installed on the junction box. The light receiving and transmitting interface assembly is accommodated in the accommodating pit, and an optical fiber input interface of the light receiving and transmitting interface assembly penetrates out of the through hole in the side wall of the accommodating pit to be connected with an optical fiber in the junction box at the back of the accommodating pit. The optical fibers in the junction box are usually left with a certain length, and if the optical fibers are directly connected to the optical fiber access interface of the optical transceiver interface assembly on the panel without coiling, the optical fibers are likely to be sharply bent, which causes problems such as fiber breakage or signal conversion failure. In order to solve the problem, the panel is usually used with a junction box having a fiber winding post, the optical fiber in the junction box needs to be wound on the fiber winding post in the junction box, and the optical fiber is connected to the optical fiber access interface on the back of the panel after the winding is completed. If the junction box provided with the fiber winding column is not used, the side wall of the accommodating pit is required to be used as a fiber winding structure, and the optical fiber is wound around the side wall of the accommodating pit on the back surface of the accommodating part, and the winding mode has the following defects: (1) the optical fiber is difficult to keep fixed after being coiled around the side wall of the accommodating pit and is likely to scatter or fall off, so that the difficulty of fiber winding is increased; (2) the cross section area of the existing accommodating pit is large, the gap formed between the peripheral side of the accommodating pit and the junction box is small, and the optical fibers wound on the side wall of the accommodating pit occupy the gap between the peripheral side of the accommodating pit and the junction box, so that the accommodating pit is difficult to sink into the junction box, and the panel is difficult to mount on the junction box.

Detailed Description

The invention is described in further detail below with reference to specific embodiments.

As shown in fig. 1, the PON terminal panel includes a main body 1, and a receiving hole 131 is formed in the main body 1 so that the middle portion thereof is curved toward the rear. The receiving hole 131 receives an optical transceiver interface assembly having an optical fiber input interface 1212. The cross section of the pit 131 is in a shape with a recess 132 (see fig. 2, the dashed line frame at the upper left of the pit 131), and a fiber notch 1311 leading to the recess 132 is formed in the wall of the pit 131 for exposing the fiber input interface 1212 for connecting the fiber. The bottom wall of the pit 131 is provided with a ring groove 1321 on the back, the ring groove 1321 is provided with a fiber outlet 1322 leading to the notch 132, and four fiber clamping members 1323 are arranged on the bottom wall of the pit 131 along the ring groove 1321 at intervals. When an installer or a maintenance person needs to perform operations such as wiring and fiber winding on the PON terminal panel, the optical fiber in the terminal box is taken out first, so that the optical fiber is trapped in the ring groove 1321, is wound along the ring groove 1321, and is clamped and fixed by the fiber clamping member 1323. After the optical fiber is coiled, the optical fiber connector is led out from the fiber outlet 1322 to the notch 132 and is connected into the optical fiber input interface 1212. Because the optical fiber connector at the tail of the optical fiber has a certain length, if the recess 132 is not enough to accommodate the whole optical fiber connector, the optical fiber connector led out from the fiber outlet 1322 may need to be bent sharply to wind around the recess 132 to be connected into the optical fiber input interface 1212, which may cause problems such as fiber breakage or signal conversion failure. In contrast, the fiber outlet 1322 of this embodiment widens toward the fiber input interface 1212 compared to the annular groove 1321, and the fiber connector can be led out in the direction after being coiled in the annular groove 1321, and then is coiled to the notch 132 and is connected to the fiber input interface 1212 through the notch 132, so that the fiber does not need to be bent sharply (as shown by a line a in fig. 2). If the fiber outlet 1322 does not extend toward the fiber input port 1212, the optical fiber may be sharply bent as indicated by a line B in fig. 2 after being drawn out from the fiber outlet 1322, which may cause problems such as fiber breakage or signal failure. Since the annular groove 1321 is formed in the bottom wall of the accommodating recess 131, the optical fiber wound in the annular groove 1321 does not occupy a gap between the peripheral side of the accommodating recess 131 and the junction box, and does not prevent the accommodating recess 131 from sinking into the junction box, so that the PON terminal panel can be easily mounted on the junction box.

The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
