Operating and handling precautions
(1) This product employs open type package. Be careful not to touch directly to a gold wire, a laser chip, and a monitor sub-mount chip, or
characteristics may be damaged.
(2) The lead pins of this product consist of silver-plating.
Do not operate under the conditions of freezing or due formation. The use in such condition may cause short circuit due to silver
migration.
(3) Please finish soldering within 7 days, or keep the products in the N
2
-purged box after opening the package to prevent them from silver
oxidization or damage to solderability.
