GPFD Cards - What are they and what are they used for?

GPFD cards are components used in fiber optic networks that enable the processing and transmission of data in the form of light. GPFD stands for "Gigabit Passive Optical Filter Device." These cards are employed in Gigabit Passive Optical Network (GPON) systems and ensure stable and fast data transmission. They are crucial elements in fiber optic networks and form the basic building blocks of network infrastructure.

In what situations is it beneficial to use GPFD cards?

GPFD cards are essential in GPON systems, which are increasingly common in the construction of fiber optic networks. With the use of these cards, data can be transmitted at speeds of up to 2.5 Gb/s in symmetrical technology and up to 1.25 Gb/s in asymmetrical technology. GPFD cards allow the division of the optical signal into multiple channels, enabling the transmission of signals to multiple recipients simultaneously. Therefore, GPFD cards are indispensable in the construction of fiber optic networks in residential, office, and public utility buildings.

Types of GPFD cards

Depending on network requirements, various types of GPFD cards are available. One type is the OLT GPFD card, which enables the processing of optical signals in Optical Line Terminal (OLT) devices. GPFD cards are also available in versions with one or two inputs and with different types of connectors, allowing them to be adapted to various network devices. It is also important to consider the technical parameters of GPFD cards, such as maximum data transmission speed, the number of optical channels, and signal attenuation.

Why choose GPFD cards?

GPFD cards are a crucial element in building fiber optic networks. The use of GPFD cards allows for the transmission of optical signals over long distances and to multiple recipients simultaneously. These cards enable high-speed data transmission and are also easy to install and configure
