FAQs
What are the design challenges for 400G/800G ethernet applications using optical interconnects?
- Optical modules have high power consumption. A 400G module consumes around 12W and a 800G module may consume up to 20W.
- Optical modules require advanced low loss materials which are expensive.
- Optical modules have a shorter lifespan and are less reliable compared to active copper cables. Data center operators need to constantly maintain and replace the failed optical modules.
