Fully understand EPON, GPON

PON (Passive Optical Network) is a passive optical network, which means that the ODN (optical distribution network) between the OLT (optical line terminal) and the ONU (optical network unit) does not have any active equipment, and only uses optical fibers and passive components. PON mainly adopts... Read More

What do the fiber optic transceivers TX and RX mean, and what is the difference?

Optical fiber transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals.

Ten common faults and solutions of optical fiber transceivers

Fiber optic transceivers are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fibers to extend the transmission distance. They are usually located at the access layer of broadband metropolitan area networks, and are widely used in various mo... Read More

How to distinguish optical access network OLT, ONU, ODN, ONT

An optical access network is an access network that uses light as a transmission medium, replacing copper wires, and is used to access each home. An optical access network generally consists of three parts: an optical line terminal OLT, an optical network unit ONU, and an optical distribution net... Read More

How to judge whether there is a problem with the fiber optic transceiver?

In general, the luminous power of the optical fiber transceiver or optical module is as follows: multimode is between 10db and -18db; single mode is 20km between -8db and -15db; and single mode is 60km is between -5db and -12db between. But if the luminous power of the fiber optic transceiver app... Read More
