EDFA Output Power Adjustable
With one tap, you can switch to APC mode. It keeps the output power you set and adjusts from -10 ~+0.5dBm in real time. Use the touchscreen keyboard to change the target value for guaranteed, stable performance.
Startup Right Away, with Calibration
Get everything working in a matter of seconds. When EDFA starts up, it immediately shows the input power with an accuracy of ±0.2dB and automatically calibrates itself. It is ready from the start in the default, stable APC mode.

RF Video Overlay on XGSPON & GPON
The Cost-Effective Path to Triple-Play Revenue
RF overlay on xPON, As telecoms aim to reduce churn and increase revenue by providing triple-play services (video, telephony, and high-speed internet access), they must find a cost-effective way to deliver TV and video to customers.
How It Works: Combining RF Video with Premlink PON EDFA
Premlink’s PON EDFA can enable an RF overlay solution that allows standard point-to-multipoint xPON systems (such GPON, EPON, XGPON, and XGSPON) to deliver broadcast TV services efficiently. This approach uses the current optical infrastructure by adding a distinct wavelength for video, which is different from the data streams (downstream: 1490nm / 1577nm; upstream: 1310nm / 1270nm).
A Big Step Forward for Network Evolution and Efficiency
The addition of RF video overlay is a big step forward for the telecom industry. It lets service providers get the most out of their current network investments while also fulfilling modern consumer needs for a single platform that offers complete, high-quality video and data services.
Making it Easy to Move to Future Services
This mixed method gives you a lot of strategic freedom. Operators can smoothly go to full IPTV at their own speed, using both RF and IP delivery techniques at the same time. They don’t have to pay for expensive, outside set-top box conversions or a total network revamp right now.
Integrated Solutions for Triple-Play Networks
Triple play services can be defined as a high-technology combination of telecom, television, and the Internet that can be accessible through a single transmission platform or by operating a shared network. Three networks are proposed, but only one is used for TV, Internet, and telephone, utilizing all network resources. Premlink has series products for triple-play networks.
CATV Broadband
Getting with 1550nm from transmitter / EDFA to our optical receivers, subscribers are able to see CATV easily, or use our triple play ONU that has an RF output port to access CATV at once.
Passive Optical Network
Our optical receiver and EDFA are enabled with PON pass through port, the port is for 1310/1490nm or 1310/1490/ 1277/1570 nm wavelengths, which is available with GPON or XGSPON & GPON networks.
Fiber to the Home
Our xPON ONU is fit for FTTH applications, and also using with our FTTH optical receiver and optical Node, combines with regular PON ONU for different applications.

How does EDFA/EYDFA Work?
The working principle is based on the unique property of the erbium-doped fiber (EDF). The erbium-doped fiber (EDF) is exposed to a specified optical wavelength (either 980 nm or 1480 nm). Then, erbium ions within the fiber are activated to a higher energy state. The excited erbium ions return to their ground state and emit photons of the same wavelength as the transmitted optical signal, which is typically in the 1550 nm range (1525-1565 nm). This wavelength is the most often used for long-distance fiber optic communication.
