  • Passive Fiber Optic User Access Equipment and Routers

    Passive Fiber Optic User Access Equipment and Routers

    A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. In this use, a PON has a point-to-multipoint topology in which an ISP uses a single device to serve many end-us. Components and characteristicsA passive optical network consists of an (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of (ONUs) or Passive optical networks were first proposed by in 1987. Two major standard groups, the (IEEE) and the. A PON takes advantage of (WDM), using one wavelength for downstream traffic and another for upstream traffic on a (ITU-T, typically OS2). BPON, EP.

  • Inter-switch access links

    Inter-switch access links

    The ISL is proprietary of Cisco and is used only between Cisco switches. It operates in a point-to-point VLAN environment and supports up to 1000 VLANs and can be used over Fast Ethernet and Gigabit Ethernet links only. When a switch port works in access mode, it is called an access port. Configuration of VLANs other than VLAN 1 then to carry traffic of these VLANs, user has to make a switch port trunk which is connected to another switch. Cisco recommends that you have knowledge of VLANs and trunking. ISL works by encapsulating a frame in an ISL.

  • What type of switch is used in the access layer

    What type of switch is used in the access layer

    The access layer consists of layer 3 switches, which take routed and switched data packets from the distribution switches and then route them to the access devices in subnets. The access devices in subnets can be modems, video display units, receiver audio phones, IP-based. The layer 2 switches collect the data from core switches, identify the type of data packet and the address of the access device. Therefore, this. An access switch is a network edge device that directly connects end-user hardware such as computers, IP phones, wireless access points, cameras, and IoT devices to the broader network. In a typical enterprise network architecture, the access layer serves as the entry point for end.
