Frequently Asked Questions
What is the maximum supported transmission distance for this module?
Using PCF (Note 4), the module can achieve a minimum of 0.2 m up to 1000 m.
What precautions must be taken when disposing of the TODX294 module?
Since it contains GaAs, do not break or dissolve the product, and ensure disposal follows appropriate regulations; never mix with general garbage.
How frequently should I check the light emitter's performance?
Because lifetime is influenced by operating environment, regular maintenance including checking the optical output amount is recommended.
