0.1dB Grade - SM Ultra Low Loss
The 0.1dB Grade is Diamond’s proposal for a Grade A definition for IEC quality grade standards. At this time there is no formal definition for the Grade A in IEC standards, nevertheless, Diamond is promoting this qual- ity grade under the 0.1dB Grade name.
0.1 dB Grade Optical Interface
􏰀 ACA, eccentricity
􏰀 Exit angle
􏰀 0.1dB Grade ferrules: low diameters tolerance
􏰀 Ultra polish with 100% Endface inspection
This quality grade retains it’s name for the performance obtained with ITU G.652 D fiber which corresponds to a 0.1dB at 97% limit, random mated according to IEC 61300-3-34.
Applications
􏰀 High quality networks
􏰀 High speed networks and equipments 􏰀 Interferrometry systems
VIS/NIR - SM Low Wavelength
Small core fibers used mostly for visible and near infrared wavelengths (VIS/NIR), have not been addressed by standard groups. The ACA technology allows Diamond to provide the following specifications.
VIS/NIR Optical Interface
􏰀 ACA, eccentricity
􏰀 Exit angle
􏰀 0.1dB Grade ferrules: low diameters tolerance 􏰀 Ultra polish with 100% Endface inspection
< 0.125μm < 0.6°
< 0.2μm
Applications
􏰀 Bio-Medical diagnostics and treatment 􏰀 Visible light laser
< 0.125μm < 0.4°
< 0.2μm
