Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] Generally, the supported interfaces of switches can be roughly divided into three types of packaging: SFP+, QSFP+ and XFP. The present invention currently supports module communication conversion between SFP+ and QSFP+. In order to further explain the technical solution of the present invention, these two types of packaging are first discussed here. difference. Such as figure 1 As shown, the system for communication between the compatible SFP+ optical...

Abstract

A system and method for communication between an SFP+ optical module and a QSFP+ switch interface, the system includes a transfer card, and the transfer card includes a set of SFP+ gold fingers conforming to the SFP+ protocol, a set of QSFP+ gold fingers conforming to the QSFP+ protocol, and a single-chip microcomputer; The adapter card communicates with the SFP optical module through the SFP+ gold finger, and communicates with the QSFP switch through the QSFP+ gold finger; Two different protocols are converted, so that the module under the SFP+ protocol can respond under the QSFP+ port to realize the data communication between the SFP+ optical module and the QSFP+ switch.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a system and method compatible with SFP+ optical modules and QSFP+ switch interface communication. Background technique [0002] In the communication network, the optical module at the physical layer greatly limits the transmission rate of the communication network. In the optical module industry, in order to improve the compatibility of the optical module, the Storage Networking Industry Association (SNIA) has formulated the optical There is a unified standard in the module industry, but under the demand for the continuous improvement of communication speed, the optical module has derived different packages of four channels and single channel. For switches, modules with different packages cannot be used, which greatly limits the optical module. practicality. [0003] In order to solve the practicability of optical modules and reduce unnecessary switch purchase expenses, the...
