What is the normal value of current for optical modules?
Knowledge Base + 2024.02.02

Below 180mA, according to the working principle of optical module, normal 1.25G optical module working current is below 180mA to work normally, so the working current of optical module is below 180mA. However, with the increasing use of time limit, many of the old module operating current will be more than 220mA, so this module will be very hot in the working state, when the ambient temperature becomes high, it will reduce the sensitivity of its work, thus reducing the quality of communication.
