Double Concave Cylindrical Lens
Double concave Cylindrical Lens has two outward surfaces.
Cylindrical lenses are typically applied to focus incoming light to a line, or to change the aspect ratio of an image. they are used for the optics, lasers, medical science, electronics, tele-communication and others.

Application:
Â
1. All types of fibre patch cord with different structures
2. High speed optical routes for Fibre-To-The-Home networks (FTTH)
3. Cables with extreme low bending requirements
4. Small-sized optical component
Â
Characteristics:
Â
1. Superior to standard ITU-T G.657.B3 fibre, bending radius down to as small as 5mm and full compatibility with all G.652.D fibres.
2. Low attenuation satisfying the operation demand in O-E-S-C-L band
3. Low microbending loss for highly demanding cable designs including ribbons
4. Accurate geometrical parameters and large MFD which insure low splicing loss and high splicing efficiency High nd value satisfying long service life in minimum bend radius
