4. Regulatory Information
LITELINK can be used to build products that comply
The information provided in this document is intended
with the requirements of TIA/EIA/IS-968 (formerly
to inform the equipment designer but it is not sufficient
FCC part 68), FCC part 15B, TBR-21, EN60950,
to assure proper system design or regulatory compli-
UL1950, EN55022B, IEC950/IEC60950, CISPR22B,
ance. Since it is the equipment manufacturer's
EN55024, and many other standards. LITELINK com-
responsibility to have their equipment properly
plies with the requirements of UL1577. LITELINK pro-
designed to conform to all relevant regulations,
vides supplementary isolation. Metallic surge
designers using LITELINK are advised to carefully
requirements are met through the inclusion of a Sidac-
verify that their end-product design complies with all
tor in the application circuit. Longitudinal surge protec-
tion is provided by LITELINK’s optical-across-the-
barrier technology and the use of high-voltage compo-
nents in the application circuit as needed.
