Problems solved by technology

[0002] At present, when a video conference is held, only one 2M channel is equipped, and due to the limitation of the transmission channel, when several video conference rooms are switched to use at the same time, it is necessary for the operation and maintenance personnel to transfer the 2M channel to the optical communication equipment of the ground network. The 2M plug is often switched at the signal input end, and then sent to the room where the TV phone is to be turned on.

Embodiment Construction

[0005] The embodiment is described in detail in conjunction with the above drawings. A 2-megabyte output line is drawn from the output end of the upper-end optical fiber network communication device to connect to the transfer switch, and three 2-megabyte cables are respectively drawn from the transfer switch to connect with the lower-end optical fiber network communication device. The 2 megabyte shielded cable on the input terminal is connected. When the provincial network video conference is held, the provincial conference signal can be transmitted through the ground network communication equipment to different conference rooms of the municipal bureau by simply flipping the switch.

Abstract

The invention discloses a signal repeater. A 2M outputting line introduced from an output end of an upper end optical fiber network communication device is communicated with a change-over switch. Three cables are respectively introduced out of the change-over switch and connected with 2M shielding lines of an input end of a lower end optical fiber network communication device. The signal repeater has the advantages that the signal repeater is introduced from a network optical fiber communication device of a superior level, arranged in a communication computer room and has several output connection with different places and the switch for controlling is connected above. A lower level can shift the switch to achieve connection with a television conference room where a conference is held based on actual needs of the conference. Thus, the signal repeater is simple, convenient, practical and capable of effectively ensuring that a television and telephone conference can be held.

Description

Technical field: [0001] The invention relates to a signal transponder, which is especially suitable for switching when a video conference is held. Background technique: [0002] At present, when a video conference is held, only one 2M channel is equipped, and due to the limitation of the transmission channel, when several video conference rooms are switched to use at the same time, it is necessary for the operation and maintenance personnel to transfer the 2M channel to the optical communication equipment of the ground network. The 2M plug is often switched at the signal input end, and then transmitted to the room where the TV phone is to be turned on. Invention content: [0003] The task of the present invention is to propose a signal transponder which is convenient, practical and does not require frequent plugging and plugging. The task of the present invention is accomplished in this way, and it is characterized in that: a 2-megabyte output line is drawn from the outpu...
