Signal Attenuation in Long-Distance Optical Modules: A Complete Guide
When a long-distance module transmits signals over relatively short distances—or when the receiver is too close to the transmitter—the intense optical signal may directly saturate the

Long-distance Optical Modules Directly Connected to Short-distance
If directly connected to a short-haul fiber (such as a 10km fiber), the optical signal attenuation is insufficient, and the optical power at the receiver far exceeds the limit.

Long-distance Optical Modules Directly Connected to Short-distance
To compensate for signal attenuation over long transmission distances, long-haul optical modules (such as 40km and 80km modules) transmit at higher optical power.
