WebbIn a recirculating loop, a trigger-controlled setup sends an optical signal-under-test on several roundtrips around an optical fiber loop, enabling the simulation of long-haul transmissions (> 100 km) without the need for ultra-long spans of fiber or multiple amplification systems.1 WebbIn a dedicated loop, a circulation pump is mounted on a pipe connected to the water heater. The water is then constantly pumped past fixtures and appliances until a valve is opened at that point. Because it is kept continuously hot, hot water is literally available on demand at any time.
