Description

Apparatus for tag recognizing of optical transceiver adapter.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to optical fiber connectors and optical transceivers in the form of receptacles used in optical communication systems and devices. The optical transmission / reception adapter has a function of recognizing the identifier, so that the information of the optical fiber connector to be fastened is recognized and stored therein or output to an external system. The present invention relates to an apparatus for recognizing connector characteristics of an optical transmission / reception adapter capable of implementing OAM (operation, administration, maintenance) functions such as operation, maintenance, and maintenance in an optical communication system and an optical communication network.

There are various types of optical transceivers in the form of optical fiber connectors and receptacles used in optical communication devices and systems.

Commonly used fiber connector types include SC type (square connector), LC type (local channel), ST type (straight tip), FC type (fiber transmission system connector), Bi type (biconic connector), and MU type (miniature unit). In addition, as the type of optical fiber used for the optical fiber connector, a single-mode fiber and a multi-mode fiber are used.

The type of receptacle-type optical transmit / receive adapter is a multi-source agreement (MSA) standard that defines the electrical and physical characteristics of optical components among optical communication companies and organizations for compatibility of optical transmitters and receiving devices of manufacturers. SFF (small-form factor), SFP (small form-factor pluggable), SFP + (enhanced SFP), XFP (10Gbps small form-factor pluggable), XPAK, X2, XENPAK. In addition, when two optical fiber connectors are fastened in two directions, a simplex is called a simplex, and when a separate optical fiber connector is fastened to perform transmission and reception functions, it is called a duplex.

The various optical fiber connectors mentioned above may be fastened or inserted into a receptacle optical transmission / reception adapter according to the type of the connector so as to transmit an optical signal transmitted from the optical communication network to the optical transmission / reception adapter, or optical signals generated by the optical transmission / reception adapter. It transmits to the communication network.

Figure 1 shows a state in which a conventional optical fiber connector is coupled to the optical transmission and reception adapter. With reference to this figure, the optical connection structure of the conventional duplex receptacle optical transmission / reception adapter and optical fiber connector is demonstrated.

The duplex receptacle optical transmitter / receiver adapter 10 is composed of an optical transmitter 100 and an optical receiver 101 formed in parallel, and the optical fiber connector 20 is connected to the first optical fiber connector 20a and the second optical fiber connector 20b. The first optical fiber connector 20a is connected to the optical transmitter 100, and the second optical fiber connector 20b is connected to the optical receiver 101.

 The duplex receptacle optical transmitter / receiver adapter 10 converts an input electrical signal S1 into an optical signal in the optical transmitter 100, and output light S2 of the converted optical signal is coupled to the optical transmitter 100. It is output to the optical fiber OF1 through the optical fiber connector 20a.

The optical signal S3 input from the optical fiber OF2 of the optical communication network is converted into an output electrical signal S4 through the optical receiver 101 fastened to the second optical fiber connector 20b and output. The above configuration is the same in the simplex receptacle optical transmission / reception adapter, except that one optical fiber connector is used to connect the input / output optical signal to the optical transmission / reception adapter.

In such a conventional optical transceiver, the optical fiber connector simply serves as a transmission medium that transmits or receives an optical signal to the optical transceiver, so that management information of a separate optical fiber connector may be allocated, collected, and monitored by the optical transmitter / receiver adapter for higher optical communication. There is no need to perform the function of transmitting to a system device or generating a warning signal in the event of a problem in a fiber optic connector.

However, the optical fiber connector does not merely serve as a transmission medium, but also manages functions such as wavelength management for selecting, dividing and combining optical wavelengths, which are the main communication resources of the optical network, or attenuating input / output light intensity and controlling the polarization state of input / output light. In this case, optical characteristics and fastening characteristics of the optical fiber connector need to be recognized and managed in the optical transmission / reception adapter.

As an example, Korean Patent No. 10-206179, “Bragg Grating Embedded Fiber Optic Connector”, proposes a connector in which an optical fiber Bragg grating is embedded, which reflects only a specific wavelength band inside the fiber connector. This Bragg grating built-in fiber optic connector is inserted into the transmitter optical subassembly (TOSA) of the receptacle optical transmitter / receiver adapter to form an external resonant laser, so that the optical signal is output only in the wavelength band selectively reflected by the Bragg grating. Dense Wavelength-Division Multiplexing (DWDM) optical communication network.

As another example, US Pat. No. 6,522,485, "Optical connector," discloses a structure in which an optical accessory having an optical attenuation function is inserted into an optical fiber connector. The optical accessory is structured to be integral with the optical fiber connector housing while being detachable in order to improve the optical fiber connector assembly process efficiency.

As another example, US Pat. No. 7,018,108 discloses an optical fiber connector structure in which a polarization axis can be used to finely adjust and then fix the polarization axis.

In the optical communication system using the optical transmission / reception adapter with the optical fiber connector fastened as described above, the optical fiber connector not only serves as a simple optical transmission medium but also has to apply information signals such as optical characteristics and fastening characteristics of the optical fiber connector to the system. There is. Specifically, when performing various functions such as OAM (operation, administration, maintenance) in order to maintain and maintain the system in the operation of the optical communication network, the characteristics of the optical fiber connector must be recognized by the optical transceiver module and transmitted to the upper optical communication system. There is a need to do so.

The connector identifier 30a includes a resistor 312 that outputs a DC voltage from the signal generator 300a that generates any fixed DC voltage to the connector identifier 40a.

The DC voltage output from the signal generator 300a is divided by the ratio of the resistance value of the connector identifier 40a and the resistance 312 of the connector identifier 30a. The voltage signal across the resistor of the connector identifier 30a is converted into a digital signal by a signal detector 301a, which is an ADC, and then input to the software-based signal analyzer 302a.
