Embodiment Construction

[0050] Examples, please refer to Figure 7 , which is a structural diagram of an optical communication system according to a preferred embodiment of the present invention. The optical communication system 100 includes a first optical transceiver module 110 , a second optical transceiver module 120 and an optical function module 130 . The first optical transceiver module 110 includes a plurality of optical signal transmitters 112a, which are used to transmit optical signals with wavelengths λ1, λ3, . . Through the function of the optical multiplexer 114a, all the optical signals with the wavelengths λ1, λ3, ..., λ2n-1 (n is an integer) are combined, and transmitted to the three-port optical signal through the optical wave guide device. Circulator (three-port optical circulator) 116 . The three-port optical circulator 116 is a one-way optical path conversion device. For example, when an optical signal is input from port 1, it is output from the next port, that is, port 2; , ...

Abstract

The invention relates to a bidirectional wavelength optical functional module having multiple task optical communication systems, which comprises at least a wavelength management module containing a plurality of port ends, and coupled between a first optical transceiver and a second optical transceiver, which provide a first and a second optical channel respectively and can be used to transmit a plurality of optical signal of wavelengths, and at least a unidirectional optical functional module possessing the optical isolation function which is coupled between some of the port ends of the wavelength management module. The beneficial effects of the invention are easy expansion of the channel number, low plug-in loss and high optical insulation property.

Description

Technical field: [0001] The invention relates to an optical communication system technology, in particular to a bidirectional wavelength optical functional module with a multi-task optical communication system. Background technique: [0002] In the communication transmission of audio and video or other high-speed data transmission applications, the use of optical systems with high transmission efficiency is currently being adopted. This is because the optical communication system has a very wide bandwidth for the transmission of information signal channels. Although optical communication systems have broadband characteristics, in many existing systems, each optical fiber used to transmit information signals is only used for one-way transmission (one direction communication). Some current optical communication systems are briefly described below and their shortcomings are discussed. figure 1 It is a known dual-fiber transmission device 10 for transmitting and receiving opti...
