Can fiber optic cables be pointed directly at the eye
Never look directly into a fiber optic cable — active or presumed inactive (verification impossible with the naked eye). Turn off the laser source before connecting or disconnecting a cable. The light that exits an optical fiber is also spreading out in a cone, so the farther away from the end of the fiber your eye is, the lower the amount of power your eye receives. If you are using a microscope, which can efficiently focus all the light into your eye, it should have infrared filters. Working with fiber optic cabling requires precision, skill, and a strong understanding of cabling safety.

Fiber optic cables can be directly fused with pigtails
Choose pigtails for permanent splicing into your fiber backbone. Get the wrong connector type, the wrong polish, or skip proper fusion splicing technique—and you're looking at elevated signal loss, increased back reflection, and a. Fiber pigtails are simple in appearance, yet essential in function. They are the bridge between fiber optic cables in the field and the equipment or patch panels that manage them. The connector end plugs into devices like transceivers or patch panels, while the bare end is typically fusion spliced to a fiber optic cable. A fiber pigtail is a short length of optical fiber that comes with a high-quality, factory-polished connector already installed on one end, leaving a length of exposed glass on the other.
