* Question
| What factors need to be considered in the design of optical transmitters? |
* Answer
| The design of the optical transmitter must take into account factors such as cost, size, and power consumption of all external modulators.In order to reduce engineering complexity, it is important to consider modulating the laser directly from the pump source.Despite this, even with the challenges of modulators, high-bandwidth optical communication systems are likely to still use lasers instead of LEDs. |
