EDFA Amplifiers: Low Latency

SKU: EDFL

The EDFL serials of erbium-doped fiber amplifier features a very short latency for applications which require minimum signal delay. The EDFL is built using semiconductor lasers, WDM, isolator, and erbium-doped fiber. The product has the advantages of high reliability, high power output, high gain, and low noise. Two configurations are available: A preamplifier for slight optical signal amplification and a Booster amplifier for maximum output power. We make both random polarization and polarization maintain versions. It has several package configuration choices. A Benchtop unit that is preset at the highest gain is suited for laboratory use. The Benchtop has a computer control interface and GUI. The compact module is suited for system integration with the universal control interface. The pluggable and the associated host net-control rack are standardized for local network build-out. Customer configurations are available.
The EDFAs have both ACC mode ‒ automatic current control or constant current control and APC mode ‒ automatic power control settable via GUI. In the ACC mode, the pump laser’s current is set by the user and automatically locked by the EDFA to achieve a constant pumping current. The EDFA’s output power is proportional to the input power and has output even though the input signal is weak. In the APC mode, the user sets the output power, and the EDFA automatically maintains the output constant in a feedback laser pump control way. When the input optical power fluctuates, the APC mode minimizes the fluctuation of the output power and is suitable for power type and line type EDFA.
The bench top or rack mount units can have multiple output channels in which the output is equally split into multiple outputs.
The EDFA has isolators on both input and output.
These Erbium-Doped Fiber Amplifiers (EDFAs) are engineered for a long operational lifespan, typically designed to function reliably for over 10 years. This durability is achieved through high-quality components and robust manufacturing processes. The design considerations include thermal management, component selection, and rigorous testing to maximize the amplifier’s longevity and efficiency.
