Pin Description
Regulatory Compliance
EYE SAFETY
This laser based single mode transceiver is a Class 1 product. It
complies with IEC 60825-1 and FDA 21 CFR 1040.10 and
1040.11.
To meet laser safety requirements the transceiver shall be oper-
ated within the Absolute Maximum Ratings.
Caution
All adjustments have been made at the factory prior to ship-
ment of the devices. No maintenance or alteration to the
device is required.
Tampering with or modifying the performance of the device
will result in voided product warranty.
Note
Failure to adhere to the above restrictions could result in a modifica-
tion that is considered an act of
“
manufacturing,
”
and will require,
under law, recertification of the modified product with the U.S. Food
and Drug Administration (ref. 21 CFR 1040.10 (i)).

APPLICATION NOTE
ATM transceivers and matching circuits are high frequency
components and shall be terminated as recommended in the
application notes for proper EMI performance. Electromagnetic
emission may be caused by these components.
To prevent emissions it is recommended that cutouts for the
fiber connectors be designed as small as possible.
It is recommended that the Tx plug and the Rx plug be
separated with a bar that divides the duplex SC opening.
