Classification of optical telecommunication equipment
Optical telecommunication equipment is generally classified as IEC Class 1 or
FDA/CDRH Class I, because under normal operating conditions the transmitter ports
terminate on optical fiber connectors. These are covered by a front panel to ensure
protection against emissions from any energized, unterminated transmitter.
The circuit packs themselves, however, may be IEC Class 1 or 1M or FDA/CDRH Class I
or Class IIIb.
