Method and system for testing jitter compatibility

摘要

A method and system for testing jitter compatibility are disclosed in the present invention, which includes: an interconnection testing board configured with a non-NRZ optical transponder needing to satisfy the board jitter performance specification, and according to the specification, testing the jitter performance of the interconnection testing board to indirectly judge whether the jitter compatibility of non-NRZ optical transponder at a line side of the interconnection testing board is qualified, wherein: at the line side and a client side of the interconnection testing board, a non-NRZ optical transponder to be tested and an NRZ optical transponder with qualified jitter performance are configured respectively, and the jitter performance of interconnection testing board is tested; if the qualified jitter performance of interconnection testing board is obtained through testing, believing that the jitter compatibility of non-NRZ optical transponder to be tested is qualified.

1. A method for testing jitter performance of a non-No Return Zero (NRZ) optical transponder, comprising:
configuring an interconnection testing board by placing the non-NRZ optical transponder to be tested at a line side of the interconnection testing board and placing a NRZ optical transponder at a client side of the interconnection testing board, wherein the jitter performance of said NRZ optical transponder satisfies a pre-defined standard, and it has been tested that the jitter performance of said interconnection testing board, with two NRZ optical transponders whose jitter performances satisfy the standard being respectively configured at the line side and the client side of the interconnection testing board, satisfies a pre-defined board jitter performance specification; performing testing on the jitter performance of said interconnection testing board configured with said non-NRZ optical transponder and said NRZ optical transponder; when it is tested that the jitter performance of said interconnection testing board configured with said non-NRZ optical transponder and said NRZ optical transponder still satisfies the board jitter performance specification, determining that the jitter performance of said non-NRZ optical transponder satisfies a requirement of jitter performance; when it is tested that the jitter performance of said interconnection testing board configured with said non-NRZ optical transponder and said NRZ optical transponder no longer satisfies the board jitter performance specification, determining that the jitter performance of said non-NRZ optical transponder does not satisfy the requirement of jitter performance.
