Description

Technical Field

[0001] The utility model generally relates to the technical field of optoelectronic signal transmission devices. Specifically, the utility model relates to a fiber optic network device with multi-network multi-standby function. Background Art

[0002] With the rapid development of fiber optic access network technology, fiber to the home (FTTH) technology has been widely applied at present.

[0034] The present utility model will be further described below with reference to the accompanying drawings in conjunction with the specific embodiments.

[0035] Figure 1 The schematic diagram of a multi-network multi-standby optical fiber network device in an embodiment of the present utility model is shown. As Figure 1 shown, the device includes an operator multiplexing device 101 and an operator separation device 102. The operator multiplexing device 101 is connected to the operator separation device 102 through drop wire optical fibers. Among them, the operator multiplexing device 101 includes a plurality of operator optical fiber input ports and an optical fiber multiplexing output port, and the operator separation device 102 includes an optical fiber multiplexing input port and a plurality of operator output ports.

[0036] The operator multiplexing device 101 can be arranged at the weak current optical fiber distribution point in the corridor. The operator multiplexing device 101 is configured to receive optical signals from multiple operators through the multiple operator optical fiber input ports, and combine the multiple optical signals through the fiber multiplexing output port and transport them to the operator separation device 102 through the drop fiber. The operator multiplexing device 101 accesses multiple operator optical fiber networks through the multiple operator optical fiber input ports. The operator optical fiber input ports can be connected to the optical line terminals (OLT) of multiple operators or the cable television network (CATV), for example.

[0037] The operator separation device 102 can be arranged at the user's place. The operator separation device 102 is configured to receive optical signals from multiple operators through the fiber multiplexing input port from the drop fiber, and transmit the optical signals from multiple operators to multiple output devices through the multiple operator output ports. The output devices can be optical network units (ONU) or cable television (RF CATV).

[0038] Due to the symmetry of the optical path, the operator multiplexing device 101 and the operator separation device 102 can be symmetrical, except that the input and output are exactly opposite. Figure 2 The structural schematic diagram of an operator multiplexing device / operator separation device in an embodiment of the present invention is shown.

[0039] As Figure 2As shown, the operator optical fiber input ports of the operator multiplexing device 101 may include a Gigabit Passive Optical Network (GPON) A port, a 10 Gigabit Symmetric Passive Optical Network (XGSPON) B port, and a Cable Television (CATV) C port. In addition, it is conceivable to set other operator optical fiber input ports. For example, a 50 Gigabit Passive Optical Network (50G-PON) D port may also be set. The A port filters out the GPON optical signals of operator A and deletes the remaining optical signals. The B port filters out the XGSPON optical signals of operator B and deletes the remaining optical signals. The C port filters out the CATV optical signals of operator C and deletes the remaining optical signals. The D port can also filter out the 50G-PON optical signals of operator D. Among them, the GPON optical signal is a 1490 / 1310 optical signal, the XGSPON optical signal is a 1577 / 1270 optical signal, the CATV optical signal is a 1550 optical signal, and the 50G-PON optical signal is a 1342 / 1286 optical signal. Here, the "1490 / 1310 optical signal" means that the upstream and downstream wavelengths of the optical signal are 1490 nm and 1310 nm respectively. The "1577 / 1270 optical signal" means that the upstream and downstream wavelengths of the optical signal are 1577 nm and 1270 nm respectively. The "1550 optical signal" means that the wavelength of the optical signal is 1550 nm. The "1342 / 1286 optical signal" means that the upstream and downstream wavelengths of the optical signal are 1342 nm and 1286 nm respectively. The A port can be connected to a 1490 / 1310 filter to filter the 1490 / 1310 optical signal. The B port can be connected to a 1577 / 1270 filter to filter the 1577 / 1270 optical signal. The C port can be connected to a 1550 filter to filter the 1550 optical signal. The D port can be connected to a 1342 / 1286 filter to filter the 1342 / 1286 optical signal. After multiple ports filter out multiple operator optical signals, the multiple operator optical signals are transmitted to the fiber multiplexing output port (COMBO). A multiplexer is provided at the fiber multiplexing output port to combine the multiple operator optical signals.

[0040] The fiber multiplexing output port is connected to a drop cable. The drop cable transmits multiple operator optical signals to the operator separation device 102 located in the user's room. The fiber multiplexing input port (COMBO) of the operator separation device 102 is connected to the drop cable to receive multiple operator optical signals. The multiple operator optical signals are transmitted to multiple operator output ports. Among them, the A port filters out the GPON optical signals of operator A and deletes the remaining optical signals. The B port filters out the XGSPON optical signals of operator B and deletes the remaining optical signals. The C port filters out the CATV optical signals of operator C and deletes the remaining optical signals. The D port filters out the 50G-PON optical signals of operator D.
