CFP MSA 100G光模块管理接口设计与实现

摘要

The CFP MSA defines the hardware interface specifications and management interface specification of CFP/CFP2/100 g CFP4 Optical module. CFP MSA management interface specification is basical technical protocol between CFP module users and CFP module suppliers and user management of the CFP Optical module is through the implementation of this protocol. By comparing the current mainstream of two kinds of CFP MDIO interface implementation plans, given 100G CFP optical module cost, power consumption, and the direction of the evolution of technology factors, the article a 100G CFP MDIO management interface design scheme, and from the two aspects of software and hardware design, combined with CFP MSA speciifcation, expounds the details of the project. This design through the strict engineering experiment, the application of the scheme, 100G CFP/CFP2 optical module has batch supply customers.%CFP MSA定义了100G CFP/CFP2/CFP4光模块的硬件接口规范和管理接口规范。CFP MSA管理接口规范是CFP模块用户和CFP模块供应商之间的基础技术协议，用户对CFP光模块的管理即通过此协议实现。文章通过对比当前主流的2种CFP MDIO接口实现方案，从100G CFP光模块的成本、功耗以及技术演进的方向等因素综合考虑，提出一种100G CFP MDIO管理接口设计方案，并从软、硬件设计2个方面，结合CFP MSA规范，对此方案进行了详细的说明。本方案设计通过了严格的工程实验验证，应用此方案的100G CFP/CFP2光模块已经批量供应客户。
