The optical amplifiers in the PON-EDFA series are designed with 1550nm RF overlay and RFoG PON applications in mind. This optical amplifier series features PON pass through connectors on each port and supports 16 or 8 outputs with optical output power per port of up to 21 dBm. Get more info about Segmentable Node
With the option to add a PON overlay network later or immediately, these units are perfect for the deployment of a RFoG architecture. Low ONT / RONU optical input levels enable best-in-class CNR, BER, and MER performance when combined with the high OMI transmitters from the Chromadigm series, lowering deployment costs while maintaining customer satisfaction.

How Do PON EDFA Optical Amplifiers Work?
An EDFA is made up of a length of Erbium-doped fibre (EDF), a WDM EDFA PON Combiner and a pump laser. The WDM combiner aids in the simultaneous propagation of the signal and pump wavelengths through the EDF.
An EDFA amplifier’s input receives an optical signal, like a 1550 nm signal. Using a WDM device, the 1550 nm signal is blended with a 980 nm pump laser. A section of fibre that has been doped with erbium ions conducts both the pump laser and the signal. Erbium-doped fibre is used by EDFA as a medium for optical amplification. The doping Erbium ions interacting help amplify the 1550 nm signal. This action boosts the signal strength by amplifying the optical signal and making it more powerful.
Advantages of PON EDFA Optical Amplifiers
These include:
- Pump power utilization at EDFA is high (>50%).
- With a comparatively flat gain, EDFA simultaneously and directly amplifies a broad wavelength band (>80nm) in the 1550 nm range.
- Optical filters that have been gain-flattened can increase flatness.
- Gain greater than 50 dB.
- Low noise figure makes EDFA ideal for long-distance applications.
- Comparatively speaking, EDFA deployment is more practical and cost-effective than other signal amplification techniques.
The most notable feature of an optical amplifier is that it can directly amplify optical signals as a component of long-distance data transmission, eliminating the need to first transform the signal into an electrical one. Erbium-doped fibre amplifiers (EDFA) are among the most widely used optical amplifiers which can amplify over long-haul optical communication.
EDFA optical amplifiers are used most widely and the technology demonstrates to be the most cutting-edge one dominating the market at present. WDM systems integrated with EDFA can benefit more from the use of WDM systems and the growing aggregate bandwidth of optical fibers.
