Optical fiber communication has rapidly developed into the main form of today’s information transmission due to its advantages of high-frequency bandwidth and large capacity. To realize optical communication, optical modulation and demodulation must be carried out. more attention. So, what is an ONU/ONT? How does ONU/ONT work?
- What is an ONU/ONT?
An optical Network Unit(ONU), also known as a single-port optical transceiver, is a product designed for special user environments. It uses a pair of optical fibers to perform single E1 or single V. 35 or single 10BaseT point-to-point optical transmission terminal equipment. As the relay transmission equipment of the local network, the equipment is suitable for the optical fiber terminal transmission equipment of the base station and the leased line equipment. For multi-port optical transceivers, it is generally called “optical transceiver”, and for single-port optical transceivers, it is generally used at the user end, and its work is similar to the commonly used baseband MODEM for WAN dedicated line (circuit) networking, but there are called “ONU, “ONT”, and “optical modems”. Optical Modem”.
What is an ONU/ONT? How does ONU/ONT work?
- Category of ONU/ONT:
There are E1 optical modems, Ethernet optical modems, and V35 optical transceivers, which are configured with corresponding service interfaces according to customer needs. E1 optical modems transmit E1 signals through optical fibers, and Ethernet optical modems transmit 2M Ethernet signals through optical fibers. V35 The optical cat transmits the V35 signal through the optical fiber. The optical cat is a device similar to the baseband MODEM (digital modem). Unlike the baseband MODEM, the access is an optical fiber dedicated line, which is an optical signal. It is a type of WAN access, which is often referred to as optical fiber access. As long as there is optical fiber, the optical cat needs to convert the optical signal.
- How the ONU/ONT works:
Optical cat equipment adopts large-scale integrated chips, simple circuits, low power consumption, high reliability, complete alarm status indication, and perfect network management function. The optical cat is a device similar to a baseband modem (digital modem). Unlike the baseband modem, it is connected to an optical fiber dedicated line, which is an optical signal. It is used for the conversion of photoelectric signals and the conversion of interface protocols in the wide area network, and the access router is the access to the wide area network. The photoelectric transceiver uses the conversion of photoelectric signals in the local area network, but only the signal conversion, without the conversion of the interface protocol.
