Regulatory Compliance
The transceivers have been tested according to American and European product safety and electromagnetic
compatibility regulations (See Table 1). For further information regarding regulatory certification, please refer
to Fiberxon regulatory specification and safety guidelines, or contact with Fiberxon, Inc. America sales office
listed at the end of documentation.

Note:
In light of item 5 in Annex of 2002/95/EC, “Pb in the glass of cathode ray tubes, electronic components and
fluorescent tubes.” and item 13 in Annex of 2005/747/EC , “ Lead and cadmium in optical and filter glass.” ,the
two exemptions are being concerned for Fiberxon’s transceivers, because Fiberxon’s transceivers use glass,
which may contain Pb, for components such as lenses, windows, isolators, and other electronic components.

EEPROM Information
The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,
standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial interface at
the 8-bit address 1010000X (A0h). The memory contents refer to Table 6.
