How does the 20 km transceiver differ from the 10 km version?

The 20 km version is designed for a higher optical budget, which allows it to compensate for the greater signal attenuation over the doubled distance.

Is it mandatory to use G.652 single-mode fiber?

The 40GBASE-LR4 standard assumes G.652D category single-mode fiber; using other types may degrade the reach or lead to transmission errors.

How critical is the cleanliness of the LC optical connectors?

The cleanliness of the connector end faces directly affects signal quality; it is recommended to use special cleaners and inspect connectors before connecting.
