Abstract
An optical fiber sub-assembly and an optical fiber connector, where the optical fiber sub-assembly includes a connector component, where a first end of the connector component is used to connect an optical cable, and where a ferrule is disposed at a second end of the connector component. Additionally, a protection tube is disposed around the ferrule, where an end surface of the ferrule protrudes from an end surface of the protection tube or an end surface of the ferrule is level with an end surface of the protection tube. Further, the protection tube has a notch, and a beveled edge is formed at an outer end of the notch.
Claims19
An optical fiber sub-assembly, comprising:
- a connector component, wherein a first end of the connector component is to connect an optical cable;
- a ferrule disposed at a second end of the connector component;
- and
- a protection tube disposed around the ferrule, wherein an end surface of the ferrule protrudes from or is level with an end surface of the protection tube,
- wherein the connector component comprises:
- a ferrule connecting member, wherein the ferrule is disposed at one end of the ferrule connecting member;
- a connecting shaft connected to another end of the ferrule connecting member, wherein the connecting shaft includes a through hole extending in an axial direction, wherein the through hole is for a cable core of the optical cable to pass through to connect to the ferrule at the ferrule connecting member;
- and
- an optical cable fixing apparatus connected to a first end, away from the ferrule connecting member, of the connecting shaft, wherein the optical cable fixing apparatus is configured to fix the optical cable, wherein the optical cable fixing apparatus comprises a rear retainer, a heat shrink tubing, and a crimping structure, wherein the heat shrink tubing is sleeved over the optical cable, wherein the crimping structure is configured to rivet an aramid yarn layer of the optical cable and the connecting shaft together, and wherein the rear retainer is sleeved over the heat shrink tubing and is connected to the first end of the connecting shaft.
