Embodiment 1

[0011] Embodiment 1: Take the photoelectric multiplexing of a single Gigabit Ethernet SFP interface as an example. In this embodiment, a physical layer chip that supports both 10 / 100 / 1000BASE-T electrical port mode and 1000BASE-X optical port mode is used, and supports Two modes of automatic selection function, the PHY chip can work in the preferred 10 / 100 / 1000BASE-T mode or the preferred 1000BASE-X mode, or the mode in which the negotiation was successful first or the previous negotiation was successful. The flow chart of this embodiment is set to the automatic selection mode that gives priority to 1000BASE-X. circuit reference image 3 , consists of a PHY unit circuit and the multiplexing device (that is, the special connector). In actual use, users can insert SFP electrical port modules or SFP optical port modules into the SFP CAGE according to needs. The following is a detailed introduction to the multiplexing method flow and multiplexing device that constitute this paten...

Embodiment 2

[0014] Embodiment 2: Take the photoelectric multiplexing of a single Gigabit Ethernet SFP interface as an example. In this embodiment, a physical layer chip that supports both 10 / 100 / 1000BASE-T electrical port mode and 1000BASE-X optical port mode is used. Large system This port can be configured to work in 10 / 100 / 1000BASE-T mode or 1000BASE-X mode by default, and the in-position signal can be identified by timing query or interrupt. This flow chart takes the default 10 / 100 / 1000BASE-T mode and the method of regularly checking whether the optical module is in place as an example. The circuit reference image 3 (see the introduction of embodiment 1 for details). The following is a detailed introduction to the process of the multiplexing method that constitutes this patent:

[0015] 1) When the large system is initialized, configure the port to work in 10 / 100 / 1000BASE-T mode. If users need to use this mode for networking, they can directly insert the 10 / 100 / 1000BASE-T SFP electr...

Description

technical field [0001] The present invention relates to the field of Ethernet switching equipment and router equipment, and mainly relates to a space multiplexing method and device for an optical / electrical interface module of an Ethernet SFP interface. In order to facilitate users to flexibly select a 10 / 100 / 1000BASE-T interface module or Space multiplexing technology of 1000BASE-X interface module. Background technique [0002] In the current Ethernet SFP (Small Form_Factor Pluggable) port solution, only 1) 100BASE-X SFP module optical interface; 2) 1000BASE-X SFP module optical interface; 3) 1000BASE -T SFP module electrical interface. The defects of the above solution mainly include: 1) the SFP electrical interface solution of 10 / 100BASE-T cannot be provided; 2) the SFP electrical interface solution of 10 / 100 / 1000BASE-T cannot be provided. At present, with the increase in the density of optical interfaces and the popularization of mixed use of optical / electrical interf...
