The first end connects a first connector, and the second end connects a second connector. At least one of the first end and the second end is located in the cooling tank. The protection tube is configured to separate the cable and the cooling liquid, and the protection tube includes at least one of a hard tube, a soft tube, or a thermal shrinking tube.

Abstract: A connector is provided, including a connector body, a fastener and an elastomer. The fastener is pivoted on the connector body with a hook end and a press end positioned on both sides thereof, respectively. The two ends of the elastomer contact the connector body and the press end of the fastener, respectively. The connector of the invention may accomplish plugging and unplugging of an electronic equipment in a single hand press way without bracer arrangement by a configuration of the press end, and may maintain an engagement state between the hook end and the electronic equipment with an arrangement of the elastomer.

Abstract: An optical-electrical converter includes a converter body, two optical-electrical conversion modules and a housing. One end of the converter body is provided with an optical fiber insertion port. The optical-electrical conversion modules are arranged on two sides of the converter body to perform conversion of optical-electrical signal, respectively. The housing is used for covering a portion of the converter body to shield the optical-electrical conversion modules. Because of multiple optical-electrical conversion modules provided by the optical-electrical converter, the arrangement number and volume of the optical-electrical converter in optical fiber network equipment may be reduced significantly to comply with the miniaturization trend of optical fiber network equipment.
