Explore Our Core Product Categories

Premium fiber optic and CATV equipment, engineered for reliability and designed to simplify your network deployment.

Optical Receiver

Made for FTTH / FTTB / FTTC networks and have GPON and XGS-PON pass-through. those receivers have AGC control and adjustable ATT, and deliver stable output levels from 76 to 110 dBµV

PON EDFA/EYDFA

Increase the reach and capacity of your PON network. Our EDFAs work with GPON, XGSPON, and Combo PON systems and come in 4 to 64 port sizes (1RU to 3RU). Some of its features are adjustable power, APC/ACC/AGC modes, and a backup power supply for carrier-grade reliability

xPON ONU

Works with all major OLTs (Huawei, ZTE, Fiberhome, Nokia). You can choose from GPON, XGSPON, or Combo versions with CATV RF for all-in-one triple-play installations

Segmentable Node

Get a high gain and output level for applications that need them. It has 2 or 4 output ports, adjustable attenuation/EQ pads, AGC/MGC options, and a high-performance CWDM DFB return laser

Optical Transmitter

Made with Ortel DFB laser technology for better signal quality. You can choose between internal and external modulation in 1RU chassis. SNMP and online management make it easy to keep an eye on things

CATV EDFA/EYDFA

The main part of high-quality CATV signal distribution. It comes in port densities of 4 to 64 and has adjustable output power, several control modes (APC/ACC/AGC), and full network management capabilities.

RF over Glass

Deliver CATV over PON. Our RFoG solutions meet SCTE 174 standards, have GPON/XGSPON pass-through, and use a CWDM DFB return laser to give off a lot of power (86/95 dBµV).

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.
