Embodiment Construction
[0043] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0044] Such as figure 1 As shown, a multi-rate bit error detection system includes a user terminal, a control module, a detection module, a crystal oscillator module, a clock module and an optical module;
[0045] The user terminal is used to send operation instructions to the detection module through the control module, and is also used to receive error data sent by the detection module;
[0046] The crystal oscillator module cooperates with the clock module to generate the first reference clock or the Nth reference clock, and when the system starts, the first reference clock is generated by default;
[0047]The detection module is used to start system initialization according to the first reference clock, and the...

The present invention relates to a multirate error code test device and method. The device comprises a user terminal, a control module, a detection module, a crystal oscillator module, a clock moduleand an optical module; the user terminal is configured to send an operation instruction to the detection module through the control module; the crystal oscillator module s matched with the clock module and is configured to generate a first reference clock or an Nth reference clock; the detection module is configured to start system initialization according to the first reference clock, and the system responds to starting of a first operation mode by default, performs first error code test or the Nth error code test according to the operation instruction and sends a corresponding pseudo-randomcode sequence to the detection module after operation, an operation result sent by the receiving module is received to collect error code data; and the optical module is configured to receive the pseudo-random code sequence and sends the operation result to the detection module after operation. The multirate error code test device and method are low in hardware cost, simple in operation and high in error code detection efficiency, and can be used for error code detection of multirate optical communication products so as to reduce the production cost.
