Integrated device based on POF and main gateway

Abstract

This utility model relates to the field of network equipment. To achieve simplified deployment and stable operation of FTTR networks, it provides an integrated device based on the fusion of POF and main gateway. By embedding the optical splitter, no additional optical fiber access is required. Compared with traditional FTTR optical signal transmission systems, the main gateway optical signal is directly coupled to it through optical patch cords. This reduces the length of optical fiber and the introduction of insertion loss from multiple equipment stages, better ensuring signal transmission and improving the user's network experience. Through power branching and the setting of a step-down module, only an AC 220V to 56V high-voltage power conversion adapter is needed, which saves manufacturing costs for manufacturers to a certain extent.

Description

Technical Field

[0001] This utility model relates to the field of network equipment, specifically an integrated device based on the fusion of POF and main gateway. Background Technology

[0002] Traditional FTTR power supply systems consist of three parts: a main gateway, an active optical splitter, and sub-gateways, such as... Figure 1 As shown. Among them, active optical splitters require consideration of power cabling, which is difficult to deploy in weak current shafts or corridors without power supply, and the cabling is complex (power lines and optical fibers need to be deployed simultaneously); active equipment has a high failure rate (statistically accounting for 32% of network failures), and may cause the entire branch network to be interrupted when power is lost or the power supply is unstable, resulting in high maintenance costs; the heat dissipation problem of the optical splitter leads to unstable performance; the series connection of multiple devices causes an additional 3-5dB loss to the system (including optical splitter insertion loss, connector loss), etc. Utility Model Content

[0003] To achieve simplified deployment and stable operation of FTTR networks, this invention provides an integrated device based on the fusion of POF and main gateway.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] The integrated device based on POF and main gateway includes a main gateway, a beam splitter, sub-gateway interfaces and cascade interfaces. The beam splitter is a passive beam splitter. The sub-gateway interfaces and cascade interfaces are all POF optoelectronic composite interfaces. It also includes a DC-DC step-down module. The external power adapter is input into the device and then splits into two paths. One path is connected to the main gateway through the DC-DC step-down module, and the other path powers the sub-gateway interfaces and cascade interfaces. The main gateway is connected to the passive beam splitter through an optical jumper.

[0006] Furthermore, each POF optoelectronic composite interface is also equipped with an overcurrent protection circuit.

[0007] Furthermore, the POF optoelectronic composite interface adopts an LC / UPC type optoelectronic composite connector.

[0008] Furthermore, the external power adapter is an AC 220V to DC 56V adapter.

[0009] Furthermore, the DC-DC step-down module reduces the voltage from 56V to 12V.

[0010] Furthermore, the passive beam splitter adopts a PLC planar waveguide type beam splitter.

[0011] Furthermore, the length of the optical jumper is less than 10cm.

[0012] Furthermore, it also includes a housing, in which the main gateway, splitter, and DC-DC step-down module are all housed.

[0013] Furthermore, the casing is made of aluminum-based heat dissipation fins.

[0014] The advantages of this invention compared to existing technologies are as follows: By integrating the optical splitter, no additional optical fiber access is required. Compared to traditional FTTR optical signal transmission systems, the main gateway optical signal is directly coupled to it via optical patch cords. This reduces the length of optical fibers and the introduction of insertion loss from multiple equipment stages, better ensuring signal transmission and improving the user's network experience. By splitting the power supply and setting a step-down module, only a 220V to 56V AC high-voltage power converter is needed, which saves manufacturing costs for manufacturers. Eliminating a power supply also eliminates the need for complex wiring layouts during installation, improving the installation efficiency of installers. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] like Figure 2 As shown, the integrated device based on POF and main gateway includes a main gateway, a splitter, sub-gateway interfaces, and cascading interfaces. The main gateway integrates routing, switching, and optical signal processing functions. The splitter is a passive splitter. The sub-gateway interfaces and cascading interfaces are all POF optoelectronic composite interfaces. It also includes a DC-DC step-down module, which is a Buck circuit that outputs 12V / 2A DC power with a ripple factor of <5%. An external AC 220V to DC 56V adapter is input into the device and splits into two paths. One path reduces the 56V to 12V through the DC-DC step-down module to power the main gateway, and the other path powers the sub-gateway interfaces and cascading interfaces. There are at least four sub-gateway interfaces, each of which transmits 56V DC power and optical signals simultaneously. The cascading interfaces are used to connect to downstream FTTR equipment. The main gateway is connected to the passive splitter via optical patch cords (such as G.657.A2 bend-resistant fiber optic patch cords) with a length of less than 10cm to avoid additional attenuation introduced by long-distance transmission.

[0019] By adopting a passive optical splitter and power supply branching, the complexity of wiring is reduced, effectively avoiding high-frequency failures caused by active optical splitters, and making the operation more stable.

[0020] To avoid short-circuit risks, each POF optoelectronic composite interface is also equipped with an overcurrent protection circuit with a protection threshold of ≤1.5A / channel. The POF optoelectronic composite interface uses an LC / UPC type optoelectronic composite connector, enabling simultaneous transmission of power (56V) and optical signals over a single cable, eliminating the need to distinguish between power cables and optical fibers during installation.

[0021] The passive optical splitter adopts a PLC planar waveguide type optical splitter, which directly couples the optical signal of the main gateway to achieve 1 to 5 (4 sub-gateways + 1 cascaded) optical distribution with an additional insertion loss of <0.5dB. When the input optical power is ≥15dBm, the optical power difference between each output terminal is ≤1.5dB, which reduces the loss by more than 3dB compared with the traditional active solution.

[0022] Furthermore, the enclosure houses the main gateway, splitter, and DC-DC step-down module, reducing the number of external connectors and minimizing potential failure points. For efficient heat dissipation, the enclosure uses aluminum-based heat sinks (thermal conductivity ≥200W / mK) to ensure stable operation of the 56V high-voltage power supply and the main gateway over extended periods. The entire device supports a wide operating temperature range of -40℃ to 85℃, making it suitable for environments without temperature control, such as corridors and low-voltage wiring shafts.

[0023] The solution of this utility model is compared with the traditional FTTR solution as follows:

[0024]

[0025] This invention integrates a passive optical splitter, eliminating the need for additional fiber optic connections. Compared to traditional FTTR optical signal transmission systems, the main gateway's optical signal is directly coupled to it via optical patch cords, reducing fiber length and the introduction of insertion loss from multiple stages of equipment. This better ensures signal transmission and improves the user's network experience. In traditional FTTR power supply systems, both the active optical splitter and the main gateway require separate adapters. However, this invention only requires a 220V to 56V AC high-voltage power converter, saving manufacturing costs for the manufacturer. Eliminating the need for an active optical splitter also simplifies the complex wiring layout during installation, improving installation efficiency and eliminating the uncontrollability and failure risks associated with active optical splitters.
