Opto-electronic adapter and communication system

An optical connector has a first connection end configured to fit with a peer adapter. The electrical connector has a second connection end configured to fit with the peer adapter. The first connection end and the second connection end have a same opening direction. In addition, the first connection end may slide along a plugging direction of the peer adapter relative to the second connection end. The first connection end is configured to be connected to the peer adapter before the second connection end. The optical connector is connected to the peer adapter before the electrical connector. This ensures that a channel for transmitting an optical signal is communicated before a channel for transmitting an electrical signal is communicated, thereby avoiding fiber burning and improving security and reliability of 1. An opto-electronic adapter comprising:

• an optical connector and an electrical connector that are stacked, wherein
• the optical connector has a first connection end configured to fit with a peer adapter, and the electrical connector has a second connection end configured to fit with the peer adapter;
• the first connection end and the second connection end have a same opening direction;
• and
• the first connection end is configured to slide along a first direction relative to the second connection end,
• the first direction is a plugging direction of the peer adapter, and the first connection end is configured to be connected to the peer adapter before the second connection end.
