AOFPLUS's breakout 6c singel mode fiber pigtail OS2 G657B1/B2 bend insensitive fiber optic pigtails have less attenuation when bent or twisted compared with traditional fiber optic pigtails and this will make the installation and maintenance more efficient. Pigtails can have female or male connectors. Female connectors could be mounted in a patch panel, often in pairs although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch fibers.
