1- G.652D Optical Fiber
The G652D optical fibre is a type of fibre that transmits only a single beam of light, that is, it is a single mode fibre (SM).
2- G.657A1 Optical Fiber
A single-mode optical fibre (SM), the G657A1 has low sensitivity to curvature, less signal dispersion, and typical application in an external access network.
3- G.657A2 Optical Fiber
Used for optical cables and indoor environments, G657A2 optical fibre is a single mode fibre (SM), which allows less signal dispersion, with low sensitivity to curvature.
