Reduced Cladding Single Mode Fibre (RC-SMF)
This reduced cladding single mode fibre is a kind of bending insensitive SM fibre with higher NA. The reduced cladding/coating dimension decreases the sensitivity of the fibre to bending losses and allows extremely tight fibre coiling with low bending losses. According to the requirement of the customer, the fibres can be specially designed to obtain variable cut-off wavelength, MFD and bending sensitivity.
- Small size of cladding and coating,Low bending loss with tight fibre coiling
- High Numerical aperture (NA) to decrease the bending sensitivity
- High coupling efficiency
- Dual-layer coating to decrease micro-bending induced loss
