Abstract:
The demand for integrated telecommunication network infrastructure has increased, and 100-Gbps optical transceivers are a critical part of this infrastructure. In this paper, an efficient firmware design scheme is proposed for a 100 Gbps C form-factor pluggable(CFP) optical transceiver based on the multi-source agreement standard for optical transceivers. In The proposed method, a field programmable gate array(FPGA) approach is used to integrate the CFP communication interface and register structure, and a microcontroller unit is employed to implement the operation of the CFP optical transceiver. This paper also proposed monitoring techniques using high-order polynomials for accurate optical power monitoring of CFP optical transceivers. To ensure that the implemented firmware satisfies the proposed design scheme, an actual testbed was constructed and the performance of the firmware was evaluated. The results demonstrate that the proposed design scheme not only satisfies standard items but also achieved an average monitoring accuracy of more than 90%. In addition, the proposed scheme can be applied to 200/400G CFP optical transceivers in the future. By implementing the CFP firmware using the proposed method, manufacturers can ensure quality while reducing cost and development time.
