A TAP cassette usually integrates both network ports and monitoring ports in a module and it includes an optical splitter, which “splits” off a percentage of the input power and sends it to a monitoring device. Instead of connecting directly to each other, each of the two endpoint nodes (switches, routers, database, etc) are connected to network ports on the TAP cassette. Optical fiber is designed to send light from a transceiver through a thin glass cable to a receiver on the other end. Operation Principle of Fiber Optical TAP Cassette Thus, TAP cassettes are a key component of any visibility system. Then traffic is copied and once the traffic is tapped, the copy can be used for any sort of monitoring, security, or analytical use. Instead of two switches or routers connecting directly to each other, the fiber optic cassette sits between the two endpoint devices connected directly to each of them. Fiber optical TAP cassette is a passive device that integrates TAP functionality into cable patching system, which requires no power of its own and does not actively interact with other components of the network. Typically, the data is used to monitor for security threats, performance issues, and optimization of the network. If you are not familiar with this type of device, the article is going to explain it to you.įiber optical TAP is an access point installed in networks that provides real-time monitoring of ports. This hardware tool enables you to monitor every bit, byte and packet of your data information. Is there any device that can achieve both data transmission and monitoring at the same time? Certainly, fiber optical TAP (traffic access point) cassette is the ideal solution. In today’s intelligent data center, real-time monitoring has become an important part to secure the network for better performance. Different types of ONT and OLT equipment are provided with high integration, flexible adaption and great reliability to meet all your requirements.ĪBC of PON: Understanding OLT, ONU, ONT and ODN If you are considering to purchase the ONT or OLT devices, FS.COM is a good place to go. ONT and OLT are indispensable components in the GPON network system. If the network can not be restored after the above methods, maybe you need to consult professionals for help. If the problem still exists, you can reconnect the ONT power supply to clear its internal cache. You can use the Ethernet cable for connection. To troubleshoot the ONT, you should remember that the most important step is to connect your computer directly to the ONT to see if the problem goes away. You need to unbind the service first before delete the ONT. ONT can’t be deleted when it has been configured with other services. Then ONT configuration data is deleted with the deletion of the ONT and the online ONT is forced offline. When you need to delete the ONT on OLT, please use the delete command. The other is the downstream direction which gets data, voice and video traffic from metro network or from a long-haul network and sends it to all ONT modules on the ODN. One is the upstream direction to distribute different types of data and voice traffic from users. There are two float directions for OLT system.
In addition, it coordinates the multiplexing between the ONT conversion devices. OLT converts the standard signals used by fiber optic service (FiOS) to the frequency and framing used by PON system. Its basic function is to control the float information in optical distribution network (ODN) to go in both directions. Optical line terminal (OLT) is the endpoint hardware equipment located in a central office of the PON network.
ONU can work in different temperature and weather conditions. A small difference between them might be the application locations. They both refer to the user side equipment in GPON network. ONT is an ITU-T term, while ONU is an IEEE term. ONT is also known as optical network unit (ONU). Data received from the customer end is sent, aggregated and optimized by the ONT to the upstream OLT. It is used at end user’s premise to connect to the PON network on one side and interface with the user on the other side. Optical network terminal (ONT) is an optical modem that connects to the termination point with an optical cable. In this article, we will mainly discuss the functions of ONT and OLT in GPON network. To realize this technology, many devices are used to support the network, such as optical splitter, ONT, OLT, etc. Gigabit passive optical network (GPON) is a point-to-multipoint access mechanism providing end users with the ability to consolidate multiple services onto a single fiber transport network.
